The Holy Driver: When Virtual Meets Reality
EDITOR'S NOTE: "The Holy Driver"—chapter six from the book AI 2041: Ten Visions for Our Future by Kai-Fu and Chen Qiufan—tells the story of Chamal, a talented and cocky young gamer from Sri Lanka who is recruited by his uncle to take part in a mysterious Chinese project. At first, the game he's been tasked with playing is like other driving simulations he's mastered, but soon it begins to dawn on Chamal that something is very different—very real—about the game's increasingly more difficult scenarios. Set roughly two decades in the future, "The Holy Driver" examines the various ethical and moral issues around artificial intelligence and autonomy that are sure to arise as the world and technology moves forward. The following is an excerpt from the chapter.
JUST AS HE HAD at the VR Café, Chamal made it to the top of the training center's ranking list in no time.
He was no longer the beginner who panicked at the sight of traffic and pedestrians. And it wasn't just driving for driving's sake. Chamal began receiving missions, with instructions from the technicians in the training center. The missions were always similar in terms of structure, but with variations in story line. Sometimes they were outlandish, like an alien invasion. Sometimes they were chillingly realistic, like a terrorist attack that caused roads to crumble and cars to crash into one another.
Complex landscapes, erratic drivers . . . nothing could ruffle Chamal. He quickly tallied the most points among the group of gamers that Yang Juan had recruited from all over Sri Lanka. The young drivers became fast friends during their daily training. Still, his cohorts watched Chamal with jealous eyes as he swaggered out of the room each day—everyone knew that more points meant more money.
Other drivers tried to pry tips and tactics out of him. Chamal tossed his hair. "I was born to drive," he said, a little too cockily.
***
CHAMAL HAD DISCOVERED THAT the game did not give him infinite routes. The landscapes that came up the most frequently were primarily replicas of real-life cities, spanning the Middle East to East Asia: Abu Dhabi Satellite City, Hyderabad, Bangkok, the Singaporean man-made island, the Greater Bay Area of Guangdong-Hong Kong-Macao, Shanghai Lingang, Xiong'an New Area, Chiba of Japan—places that, until now, Chamal had only read about online.
One day Chamal received instructions to complete a mission on the Singaporean man-made island. A disturbance on the ocean floor in North Java had triggered a tsunami and the infrasound completely paralyzed the island's automated smart transportation system. A ten-meter tsunami would hit the island in exactly six minutes. Over a hundred dysfunctional autonomous cars and their passengers were careening down the roadway, likely to crash or, like sitting ducks, be washed away.
Chamal and the other racers were instructed to seize the wheels of these vehicles, turn on manual control before more accidents could happen, and help connect the cars to the emergency network infrastructure. The network would then take over, directing the cars to the nearest evacuation zone, saving the passengers' lives.
It was the most difficult and thrilling game Chamal had ever played.
His virtual avatar hopped from one driver's seat to another, taking control of the wheel in mere seconds, evading fallen debris as he sped to safer ground. Jump. The procedure was simple and natural, as if it was a part of his nerve reflex. Jump again. As the blood-red countdown was rapidly approaching zero, a shimmering white line emerged in the gray-blue horizon on the periphery of Chamal's view, and it advanced toward the shore, thickening and rising every second.
Chamal had no time to appreciate the sublime violence of nature, nor feel any fear. He was like a ghost that possessed those massive, sturdy bodies of steel and iron, connecting them to the network, and sending them on a path to safety. The delightful sound of coins clinking against one another rang on incessantly as his score rocketed at the top edge of the screen. The corners of his mouth twitched. He could feel the flow returning to his body.
The fatal Java tsunami was closer now. Faster. Chamal wanted to earn as many points as possible before the game ended. Every millisecond that slipped through his fingers meant less tuition money for his younger siblings and less living budget for his entire family. The world—and his family—depended on the speed of his mental and physical reactions.
As Chamal was about to leap into an SUV, the roaring wall of water and foam finally caught up to him. The graphics of the game were not the best; he could even see the jaggies and pixelation as the tide swallowed him whole. Before the screen went dark, he caught a last glimpse of a few cars in the near distance that were washed away instantaneously by the merciless wave. He let out a heavy, regretful sigh. Every car he didn't save meant fewer points.
Game over.
Chamal, now back to reality, found himself drenched in sweat. He was so exhausted that he couldn't even climb out from the cockpit. Two staff members had to carry him.
Alice told him to take some time off. In the days that followed, even tasks as simple as eating with a spoon gave Chamal trouble. His hands wouldn't stop shaking. The great, ferocious tide haunted him in his dreams. That mission seemed to have deprived him of all of his energy, creating a void in his mind and body.
Chamal normally had little interest in the news, but as he lay in his bedroom recovering, he overheard a report coming from the television in the kitchen, where his parents were sitting with Uncle Junius. The newscaster was talking about a tsunami that had occurred in Kanto, Japan.
Slowly, Chamal got up from the bed and staggered to the kitchen. On the TV screen, he watched surveillance footage recorded during the final moments before the tsunami hit the coastal highway. Cars, as light and powerless as toy figures made from paper and clay, were overturned and devoured by the waves, disappearing into the dark water.
Chamal's heart raced. The scene before his eyes was uncannily familiar. The status of the roads, the position of the cars, the scattered debris . . . it was an exact replica of the final scene in the game, which had been imprinted into his mind that day.
No! That's impossible! I only played a game!
"Uncle, that was only a game, wasn't it?"
Junius was silent a moment. "Chamal, I want you to meet someone."
***
BACK AT THE TRAINING facility in the ReelX Center, Uncle Junius led Chamal through a door and down a corridor that Chamal had never seen before. At the end of the hallway, they entered an office decorated lavishly with local folk art and ornaments, resembling an absurdly large collection of holiday souvenirs.
"Dear Chamal, we meet at last."
A woman dressed in all white stood from the sofa, bent down, and reached for Chamal's hand. Shyly, Chamal offered his own. The woman's grip was sturdy and her palm warm.
She motioned for them to sit.
"My name is Yang Juan. You can call me Yang, or Jade. I understand they call you 'the ghost,' Chamal."
Chamal blushed as Yang Juan continued speaking.
"I am in charge of ReelX's Sri Lanka branch. I've seen all of your game data. Without doubt, you're born to be a driver."
By now Chamal's cheeks were burning.
"Well, your uncle told me you might have some questions. I'll do my best to answer them."
Chamal bit his lip. What should I say? How can I sound respectful, polite, and dignified, like the way Mother taught me? He wanted to choose his words carefully, but he was too worn out to think straight. "The tsunami . . . it was real." Words slipped out before he could contain them. "All of this is fake," Chamal stammered.
"This isn't exactly a question, is it?" Yang Juan winked. "You're expecting a certain kind of answer from me. You want me to tell you that the game is either real or fake—choose one or the other, right?"
Chamal's head began to spin. "Is there a third possibility?"
"Let me ask you first: Do you think the tsunami was real?"
"Of course."
"Was the tsunami in the game real?"
"That was fake."
"How about the cars?"
"The landscape seemed real and the course of action they took seemed real, but the cars themselves were fake."
"Then, do you think you really helped save those cars and people?"
"I—I—" Chamal stuttered. "I don't know."
Yang Juan shrugged, but her expression was sympathetic.
"But I know you're lying!" Chamal blurted out. "If the tsunami happened in Japan, why did you have to tell us it was Singapore? If our actions affected reality, why did you have to tell us it was a game?"
Yang Juan sat silently, letting the question hang in the air. Finally, she spoke. "Before I answer, I need to ask you something first. Only answer with yes or no." Squatting, Yang Juan lowered her body to the ground, so that she could look directly into Chamal's eyes.
"Do you want to go to China?"
"What?" Chamal was taken by surprise.
"Remember, this is a yes or no question." Yang Juan grinned upon seeing the look of astonishment and awkwardness on the boy's face. "You are our best driver. A trip to China is the bonus reward for your work. I think you'll find the answer to your question there."
"You mean driving in China?" Chamal frowned. "If that's the case, then I've been to many places in China already."
It was Yang Juan's turn to be stunned. It took her a few seconds to realize that Chamal was talking about virtual reality. "I'm not trying to trick you." Yang Juan laughed. "I meant going to China for real. You will physically take a plane and go to China, breathe the air, eat the food, and test out the landscape with your own feet. Do you want to go?"
Chamal lowered his eyes and contemplated. Finally, he looked up at Yang Juan, nodded his head, and gave the woman a dignified smile.
***
A STRONG VIBRATION WOKE Chamal from his sleep. Thinking he was still in the game, he instinctively reached for his helmet, but there was nothing on his head. He opened his eyes and squinted at the bright morning sun coming in through the porthole-shaped window. Outside were endless rows of sleek jumbo jets.
The plane had arrived at the Shenzhen Bao'an International Airport. As Chamal and his uncle walked down the jet-bridge and into the terminal, he marveled at all he was seeing. Everything here was colossal and brand-new; rays of sunlight shone through the hexagonal carve-outs on the white ceiling like a heavy meteor shower, illuminating the travelers hurrying from one destination to another.
Zeng Xinlan, a talkative, cheerful young employee from ReelX's Shenzhen headquarters, picked them up at the airport. Upon meeting Chamal and Junius, she put her hands together and said "Ayubowan," greeting her Sri Lankan visitors in their native language. Junius returned the blessing and Chamal copied his uncle.
They walked to the autonomous vehicle pickup zone together. Almost as soon as they arrived, a white SUV glided into the lane and came to a stop before them. Its doors swung open. Chamal climbed into the spacious back seat with Junius. The cool breeze of the car's air-conditioning relieved the stickiness from the humid outside air almost instantaneously.
The car took off. Unlike the cars Chamal was used to, the engine of the SUV was nearly silent, and the acceleration was so smooth that he barely felt anything.
"Most of the roads and vehicles in Shenzhen support L5-level autonomous driving now. With the driver's seat no longer exclusive to the driver, not only can we fit more people into a car, but everyone can sit more comfortably as well. Minicars reserved for one or two passengers are also available." Zeng Xinlan smiled. "The smart control system decides which available car to send and calculates the optimal path to take based on the passengers' location and walking speed, to maximize airport efficiency and reduce passengers' waiting time. The road we're on right now is specifically designed to accommodate autonomous vehicles. The smart sensors installed along the road communicate in real time with the control system on every car and the traffic management infrastructure in the cloud, to ensure safety and orderliness."
Chamal thought she sounded a bit robotic, as she recited this explanation.
Junius pressed his face against the window. "Shenzhen looks so different from the last time I visited!" he exclaimed.
"You've been to Shenzhen before?" asked Chamal, surprised.
"Many years ago. I remember seeing a construction team working on the first of these 'smart' roads—they're everywhere now!"
"Typical Shenzhen development speed," Zeng Xinlan said with a grin. "Wait till you see more!"
Chamal stared out the window at the foreign city, dazed. Skyscrapers extended upward as if they were infinite, their tips disappearing into the clouds. The outer walls of the buildings were made from smooth, shiny material that reflected sunlight, making them seem as if they were wrapped in cloaks of light that changed patterns and design when the sun's angle shifted. Shenzhen was pristine and orderly. He couldn't figure out how this was possible. It was as if millions of invisible puppet strings were hanging from heaven, controlling every road, every car, and every person in this enormous city, weaving them into an all-encompassing web.
But who's pulling those strings?
"Look!" Zeng Xinlan shouted.
Chamal and Junius looked in the direction her finger was pointing. In the lanes of opposing traffic, the vehicles suddenly parted. One by one the cars glided to the sides of the highway, creating an empty lane in the middle. A faint siren grew louder as an ambulance suddenly sped through the gap in traffic. As soon as it had passed, the cars slid back into their original positions, as if nothing had happened. The entire process took mere seconds, and, apart from the siren, was nearly silent, without so much as a single honk.
"How is this possible?" Chamal was nearly speechless.
"Think about it this way. We humans don't crash into one another when we run, because our eyes observe, our brains calculate distance, and our legs adjust speed and posture. The same goes for these cars," said Zeng Xinlan with a shrug. "The sensors, camera lens, and LiDARs are its eyes; the control system is its brain. All of the above are connected to the engine and gears, the car's legs."
"Chamal, imagine if this technology were available in Sri Lanka," muttered Junius. He remembered what had happened to his mother. She could've been saved from her heart attack if only the ambulance had been able to get her to the hospital in time. It was not the heart attack that killed her, but the traffic.
A new message alert popped up on the dashboard, and the message was broadcast in flawless standard Mandarin through the speakers.
"Oh, it's the marathon," Zeng Xinlan explained.
Before Chamal could press for details, their car changed direction, rerouting toward the nearest off-ramp. In fact, all the cars on the highway seemed to have received the same alert at once: Like a squadron of fighter jets changing formation, the traffic dispersed into new formations as the vehicles headed to the exits.
Chamal was stunned when his gaze landed on Zeng Xinlan, who had assumed the driver's seat. The autonomous vehicles back home in Sri Lanka, despite how widely they were deployed these days, were unable to shift around with such precision without the aid of human drivers. However, Zeng Xinlan, with her hands off the wheel, was obviously not operating the car.
"What's happening now?" asked Chamal.
"Aha! It's your lucky day. You're just in time to see the upgraded city traffic system in action. The city's annual marathon will soon begin, and we're all being rerouted."
Chamal stared dazedly at the traffic, trying to digest all that he was seeing and hearing. He felt immersed in a dream world.
***
BEFORE THEY VISITED REELX'S headquarters, Zeng Xinlan took them to a Cantonese restaurant in Qianhai.
Chamal stuffed his face with the foreign yet delicious cuisine, while Junius stared fixedly out the window.
"What's so interesting out there?" asked Zeng Xinlan as she picked up a shrimp dumpling and put it down on Junius's plate.
"Even . . . even the horizon has changed," murmured Junius, bewildered.
"Well, land reclamation is one of Shenzhen's long-term projects. I heard the same is happening in Sri Lanka?"
Every time Chamal passed by the coastal road in Colombo, he would catch a glimpse of the trailing suction hopper dredgers near the coast of Port City. Those behemoths lifted their long snouts and spat out arcs of mud and sand, which glistened like gold in the sun. All the dredgers came from China; they were helping Sri Lanka with the colossal feat of creating new land and reshaping the sea horizon.
"Sri Lanka, a bright pearl of the maritime silk road," Zeng Xinlan commented, mocking the tone of Chinese news broadcasters.
Chamal put down his chopsticks. "Are there any cars left for humans, then?" he asked, timidly voicing the question that had been on his mind for hours.
"Not all cars can be switched to manual mode," said Zeng Xinlan. "We have human drivers, too, but they are limited to human-only roads and they are required to use a complementary AI device while driving. It's so much more difficult to pass the driver's license exam these days. No place for hooligans."
"If that's the case, why are we needed?" Chamal turned to Junius, gazing directly into his eyes.
Junius and Zeng Xinlan exchanged glances. "Of course you're important," replied Zeng Xinlan. She looked at Chamal, her face solemn. "Even the most advanced AI makes mistakes. What if an explosion destroys a road, making it impossible to follow the digital map, or there's a natural disaster that suddenly creates chaos? This is when people like you come in—a hero to save the day."
"But I don't want to be a hero," Chamal blurted out. "I only want to play games, earn some points, and help out my family."
Junius evaded Chamal's gaze.
All of a sudden, Zeng Xinlan let out a giggle and broke the awkward silence. "Look at you two! Like uncle, like nephew. Chamal, when your uncle first joined our project, he told us the exact same thing! Am I right, Junius?"
Junius, now blushing, poked at his soup with his spoon.
"Wait, you also . . . ?" Chamal's eyes widened.
"He never told you?" Zeng Xinlan shot Junius a surprised look.
Chamal shook his head.
"I didn't want to give you the wrong impression," whispered Junius, finally finding the right words. "I know what other people say behind my back. They think I've been helping ReelX do bad things, so the Buddha decided to punish me by crippling my leg."
Chamal was not a stranger to the gossip, but he had never imagined the truth.
"Your uncle used to be our best driver. Before he retired from the injury, he saved many lives."
"So you used to be a ghost driver, just like me," Chamal repeated. "But how can ghosts get injured?"
"This was a decade ago, Chamal. It was an earlier version of the program, a more primitive version," Uncle Junius said. "There have always been risks, but they are smaller now."
"That's why it's necessary we call the procedure a game," interjected Zeng Xinlan, her tone serious again. "The human species is far more delicate than machines. A human driver's reaction time and performance level can be affected by even the most insignificant emotional response."
"So that's why Uncle lied to me, telling me that I was only there to play a game," muttered Chamal. I used to believe that Uncle would never lie to me.
"Chamal," Junius said, letting out a sigh. "Let me tell you a story."
***
A DECADE AGO, JUNIUS was conducting a mission in the SichuanTibet region after a major earthquake. His objective was to transport emergency medical supplies to the trapped victims. The aftershocks were relentless; GPS was failing due to roads blocked by landslides. Ghost drivers were the only option. At first, Junius managed to evade danger, but after an especially powerful aftershock, debris began pouring down the mountain like a deadly rain. Struggling to dodge rocks and mud while maintaining control on the winding road, Junius failed to notice a giant boulder plunging down from his left. It landed on his car hood, smashing the car's left side into the ground.
A piercing pain shot down Junius's left leg; it was the force feedback at work. He knew that his physical body was unharmed. It was synesthesia. A healthy amount of body synesthesia—simulation of real senses through virtual reality—was beneficial to virtual rescue drivers, because it stimulated cognitive capacity and produced adrenaline, enhancing their performance level. However, what constituted "a healthy amount" varied from driver to driver, mission to mission. Upon seeing the disaster-stricken Sichuan-Tibet region, Junius had deliberately pushed the synesthesia values up. So many lives depended on him; he could not bear the thought of letting them down.
With his leg screaming in pain, Junius tried different ways to get the car moving again, but it wouldn't budge; the wheels would only spin uselessly. With every passing second, hope grew dimmer. He was overwhelmed with guilt and despair. I failed them. His injured leg felt numb now, as if it were no longer a part of his body.
In the end, the military was able to pull drones from other sectors and send out an emergency deployment. The medical supplies reached the people in need, after all. However, ever since that day, Junius's leg had been stuck in a limbo between the real and the virtual, as if time had forgotten it, freezing it forever in that moment of pain and regret.
***
"IF WE THINK OF it as a game, we'll feel less pain," said Chamal, after Junius had finished talking. He could understand where Junius was coming from now, yet there was still one thing he just couldn't wrap his head around. "But why? Why do we have to endure all this?"
"To make a living, I guess, and save some lives along the way. It's important to invest in our karma," said Junius with a self-deprecating smile. "One day we may need saving, too."
After lunch, they visited ReelX's headquarters. While they were in the lab, Chamal couldn't tear his eyes away from the newest force-feedback suit and brainwave-connected helmet displayed in the window. Zeng Xinlan, noticing the boy's widened eyes, promised him a set of tailor-made equipment—as long as he was willing to stay and complete ReelX's missions.
Chamal, caressing the graphene fabric that was as light as silk yet as impenetrable as steel, silently mulled over all that he had learned that day.
Indeed, Chamal felt that he'd witnessed the future in one afternoon—although he wasn't sure whether it was the same future that Junius had mentioned. The future, in his eyes, was foreign, grandiose, and immensely confusing. The autonomous cars and smart roads that he had seen on the trip were only the tip of the iceberg. Chamal used to think that technology was like Father's car, in which straightforward, countable components like bearings, gears, and cords had been assembled piece by piece, and everything was clear-cut and apparent to the eye. Now he realized that technology was more like Mother's favorite sari: The drape was delicate gossamer, embroidered with a variety of patterns, yet when Mother folded it and wrapped it around her body, the sari looked different, like layers of hazy clouds bundled together and solidified into a definite, concrete shape.

Tokyo Auto Salon returned after a one-year, Covid-induced hiatus that saw the cancellation of 2021's expected event. And along with the various tuning firms, parts distributors, and always interesting mom and pop shop-created display vehicles, some of the OEMs take part and show off some of their more enthusiast-focused projects.One of those automakers is Toyota, which regularly attends TAS and always brings something worth a closer look. For 2022, the Toyota Gazoo Racing group went all-in for the annual auto salon with a line of can't miss display cars, throwback parts, and some high-level motorsport competitors.Toyota GR GT3 ConceptThe world premiere of the group's GR GT3 Concept is much more than an exercise in design language and a pop of performance. The idea was to take all the technology, knowledge, and experience that Toyota Gazoo Racing has earned in various forms of motorsport and put them into a single race car. Most expected a modified MkV Supra, but what they got was something entirely different.With Batmobile like proportions, the front fascia isn't like any other Toyota product, using slender lighting that sits within a small gap along the upper portion of the front bumper. The pronounced splitter, accompanied by dual canards on each end, stretches the car out a little further. Out back, a massive carbon fiber wing sits over the rear with a sculpted vents under each side of the full-width taillight. Further down you'll spot diffuser with sharp blades and, in between, the GT3 Concept badging and GR logo.The slippery coupe sports vented front fenders that add considerable width, the rear portions connected to bulky side skirts that carry into the rear quarters. Exhaust exits are integrated into the front portions of the side skirts and the sharp cuts of the aerodynamic side mirrors are an elegant touch. Rolling stock is based on center-lock wheels wrapped in Bridgestone race meats and the suspension places the car's aero just a few inches off the ground. TGR states that they'll be implementing feedback and technologies refined in motorsports competition to develop their GT3 program as well as mass-produced vehicles.GR Yaris: Bite-Sized DynamoThe fan favorite GR Yaris is on display but it's the GRMN model that everyone is talking about. Limited to just 500 units, the three-door hatchback goes on a diet, including ditching its rear seats, and the body gets increased rigidity with additional spot welds and longer structural adhesive. The car's width is increased, and its ride height reduced, both by 10mm. Upon the rear hatch is a unique carbon fiber wing that sits well above the roofline with pedestals that mount to a carbon fiber base. Oh, did we mention the entire roof is also carbon fiber to drop some weight? It is.The transmission gets closer gearing with a low final drive and a mechanical LSD will be added to the mix, while grip and cornering were also improved upon based on feedback from professional drivers who helped TGR further refine the already potent GR Yaris. Toyota says they'll be offering an Update and Personalization Program to help end-users make changes to their cars as they increase their seat time. The Update Program promises additional parts and software updates will be offered along with engine upgrades, while the Personalization Program is based on the owner's driving habits, offering steering control and shock updates, additional aero, and more.Within that group of limited-edition Yaris, 50 models will include the Circuit Package which TGR says will focus on road performance based on feedback from Super Taikyu - Asia's top endurance race series. Available only in a Matte Steel color, the package includes that interesting rear spoiler, specific side skirts and front lip, Bilstein shocks, huge 18-inch brakes under BBS GRMN wheels. An airbag-equipped, fixed-back Recaro bucket seat with motorsport-grade side mounts is available as well. The Circuit Package, along with the standard GRMN Yaris Package will be made available through GR Garages in Japan this summer using TGR's lottery system.Old Is GoldFor those that are enamored with iconic Toyota models of yesteryear, the announcement of remanufacturing OEM-spec Toyota parts for fan favorites like the MkIII and IV Supra, 2000GT, and Corolla AE86 have been celebrated by enthusiasts attempting to restore or give these older vehicles a second life. TGR announced 56 items for the group's six chosen vehicles will be added to the already 33-piece line up as production begin to ramp up. The vehicle list includes those mentioned above, along with the Land Cruiser 40 and 2000GT.
I did not win the efficiency contest here in Immendingen, Germany, home of the sprawling Test Center of Mercedes-Benz even though I had a handicap: the supremely slippery Mercedes-Benz Vision EQXX, a drivable concept car that can travel more than 1,200 km (745 miles) on a single charge.The problem was not the car, it was me. I could not help busting out of the recommended conservative driving habits to gun it when the speed limits on the handling course allowed, which hurt my score, as did the need for manual braking when a speed limit was momentarily exceeded, prompting a warning. The benchmark was 7.9 miles per kWh; I recorded only 6.4 kWh of average consumption over the 10-mile course. On the plus side, after each burst of acceleration, I used the most aggressive of the four settings for regenerative braking and racked up more than three times the extra energy and range of the benchmark driver.Which is to say, the beauty of the EQXX is that it can be fun, with a mighty torque pull, as well as efficient—I still recorded a single-digit consumption figure—so best of both worlds.And that is good because this Vision concept is the future of Mercedes EVs. The learnings and stylings will show up in new vehicles coming in 2025 and beyond from the new Mercedes Modular Architecture or MMA. The EQXX is a street-legal prototype and the only one of its kind in the world. At 110.2 inches, it is a compact car, roughly the same wheelbase as the Mercedes-Benz EQB.Its impressive range, beating the Lucid Air Grand Touring's 516 miles and the Tesla Model S Long Range at 405 miles per EPA, is attributable to a number of factors. The EQXX has a 100-kWH battery pack, similar to the one in the Mercedes-Benz EQS large sedan, but in the EQXX concept the unit is half the size and weighs 30 percent less, the cells are packaged differently and it has a carbon fiber top cover. The anodes use more silicon and hold more energy. While the rest of the Mercedes EV lineup have a 400-volt system, and some competitors have 800V, the EQXX system is more than 900V. Stumbling onto the Teardrop ShapeThe design team came up with the car's teardrop shape with the rear track two inches narrower than the front, a tapered cabin, and a long tail with an active diffuser which extends almost 8 inches. "We didn't set out to create this shape, we found it," Malte Sievers, project manager for the Vision EQXX tells us.The result: a claimed drag coefficient of 0.17—more streamlined than a football—making the EQXX the most efficient model Mercedes, or perhaps anyone, has built. It could become a car for the ages as 0.17 will be hard to beat, physics is physics, says Sievers. And this slippery missile could never be built if it had to accommodate an internal combustion engine. "The whole thing falls apart," he says. "It shows the capability EVs brings to the industry."Engineers say 62 percent of the EQXX's efficiency is from aerodynamics; meaning every change to aero affects everything else by 62 percent. You can make changes to rolling resistance, for example, but your efforts will never impact more than 20 percent of the total efficiency. And everything else amounts to an 18 percent impact. The team looked at every part to see if it was necessary and if so, how to make it light, efficient, and not heat up. The cooling plate underneath allows the car to be cooled by airflow and the overall efficiency means there is little to cool.The summation of all the engineering efforts is a car where 95 percent of the energy sent from the battery makes its way to the wheels. For reference, the EQS sends 90 percent of its energy to the wheel well, which means the team had to make the EQXX twice as efficient.First Outsiders to Drive the Mercedes-Benz EQXXWe were part of a media program that let non-Mercedes people drive the Vision EQXX for the first time. To date, only Mercedes employees have put it through its paces. That includes two road trips, the first April 5 from Singelfingen, Germany, to Cassis in northern Italy, 1,008 km (626 miles) and using 8.7 kWh/100 km or 7.1 miles per kWh, with 140 km (87 miles) left at the finish. The second run, June 21-22, was from Stuttgart to Silverstone in France, a distance of 1,202 km (747 miles) in summer heat requiring the air conditioning to run for 11 hours. Average consumption was 8.3 kWh/100 km or 7.5 miles/kWh, and it included 11 laps on the track when the car reached Silverstone to empty the remaining energy.To work out the bugs, the team created a test mule by squeezing a 100-kW battery, DC/DC converter and DC charging controls, battery management system, other aspects of the EQXX powertrain, as well as testing equipment, into a Mercedes-Benz EQB. The mule is known as EMMA (the MMA for Mercedes Modular Architecture). EMMA made the Sindelfingen to Cassis trip first in a test run with its share of breakdowns, a learning curve that proved to be a total success as the EQXX did not have a single mishap in either of its long-distance tests.We drove EMMA, who was a little clunky as the suspension was not adapted for the weighty equipment added or the fact that most of it bears down on the rear axle, throwing off the balance.Then we hopped in the EQXX which was much quieter, balanced, nimble, and downright supple by comparison, riding on Ultralight 20-inch forged magnesium wheels with Bridgestone Turanza tires that are also lightweight and have ultra-low-rolling resistance. The car cornered nice and flat, the suspension was not challenged by the course, but neither did it stumble.Impressive Regenerative BrakingBoth cars have one-pedal driving with four degrees of regenerative braking—mild, two aggressive settings, and the option to have no reclamation at all, which works infinitely better on the EQXX. On one long straight in EMMA, we turned off regen and saw our speed drop about 9 mph within seconds. In the EQXX the speed never dropped at all.Manual braking was harsher in EMMA, it was less grabby in the EQXX, but engineers wince if a foot ever touched that pedal because it means energy is being lost. We used the most aggressive regen setting for most of the EQXX drive; it was highly effective without being too harsh.There is a satisfying weight to the EQXX's steering and the vehicle is not flighty at all. Input and response are nicely married. Acceleration on the 21-minute lap was not neck-snapping but the car picked up speed quicky and smoothly. It was easy to exceed the course's varying speed limits that were being closely monitored.The big takeaway is that it felt like a production model more so than a concept.Attempting the ImpossibleThe EQXX prototype was pulled together in 18 months, a project launched with a request in June 2020 from the board of management to build an electric vehicle capable of driving 1,000 km (621 miles) on a single charge. Almost all the teams involved worked to achieve the seemingly impossible target of 10 kWh/100 km, Sievers said. The car relied on expertise from Mercedes' Formula 1 and Formula E race engineering groups as well as the research department and production development team.There are 117 heavy solar panels on the roof that send energy into a 12V system that powers many of the car's ancillaries which equates to a roughly 25-km (15-mile) bump in range. Engineers say the energy gains from the panels are greater than the losses due to the extra weight.You cannot see out the glass of the back window; nor are there cameras for the rearview mirror—they would consume too much energy.It all adds up to a highly efficient EQXX that exceeded the mandate.Loving the Luxury InteriorThe beautiful navy and white interior of the EQXX is serene and modern without looking too sci-fi or clinically cold, with sustainable vegan materials that look high end. There are 47.5 inches of curved OLED screen, perfect for using the real-time 3D navigation display—but only when absolutely necessary. The mini LEDs that backlight and dim the screen make for crackling crisp graphics. Dimming zones save power by not illuminating the parts of the screen not in use; there is zero energy consumption when the LEDs shut themselves off.Mercedes provides eco guidance. The car knows the route conditions of the trip programmed into the nav system and tells the driver to speed up or slow down to be more efficient. The driver can look at data to show energy usage, solar energy produced, air pressure and wind direction, and forecast how much energy the trip will require. Almost ready for production is an Intelligent Avator to suggest movies to watch or restaurants to stop at, saving the driver from scrolling through menus on the screen and using energy.They are tools I clearly need. Said the engineer who tried to keep a straight face as he analyzed the data spikes in my EQXX run: "I think you had fun." Then he confirmed Mercedes would not be hiring me anytime soon for their EV testing.BASE PRICE Not for sale LAYOUT Front-engine, RWD, 2+2-pass, 4-door sedan ENGINE MOTOR DC DC induction, electric, 100-kWh battery TRANSMISSION 1-speed auto CURB WEIGHT 3,900 lb (mfr) WHEELBASE 110.2 in L x W x H 195.9 x 73.6 x 53.1 in 0-60 MPH EPA CITY/HWY/COMB FUEL ECON 250 mpg-e (est) EPA RANGE, COMB 747 miles ON SALE never Show All
