The Great 2,470-Mile Kia Carnival California to Michigan Road Trip!

Is the GMA T.33 better than the McLaren F1? Gordon Murray smiles. "Oh, yes," he says. "The engine's better, the gearbox is better. It's lighter and has a slightly better power to weight ratio. The finish and the quality are much better."The McLaren F1, created by Murray in the early 1990s at the height of his fame as a rock star grand prix race car designer, is widely regarded as the seminal hypercar, a car that set absolute benchmarks for on-road performance. One sold last year for more than $20 million. The GMA T.33, Murray's new ultralight, driver-focused mid-engine coupe will be priced from about $1.85 million, plus tax, when production starts in 2024.In the context of today's McLaren F1 market, it sounds like a bargain.The T.33 is the follow up to last year's T.50, the car Murray designed specifically as a 21st century successor to the McLaren F1 and a halo for his GMA brand. Like the T.50, it's powered by a high-revving naturally aspirated V-12 and will be available with a six-speed manual transmission. But beyond elements of the powertrain—and the air conditioning system and interior switchgear—the T.33 shares nothing with the T.50. It's a completely different car, designed for a completely different purpose.The T.33's engine has less power, less torque, and a lower rev limit than the version used in the T.50 and T.50 Niki Lauda. Dubbed the Cosworth GMA.2 and distinguished by its yellow cam covers (the T.50's were orange and the T.50 Niki Lauda's red) it makes 607 horsepower at 10,500 rpm and 333 lb-ft of torque at 9,000 rpm, 47 hp and 11 lb-ft fewer than in T.50 spec. This is due to different cams, revised valve timing and engine mapping, and new intake and exhaust systems.The decision to lop 1,000 rpm from the engine's top end wasn't just a case of ensuring differentiation between T.50 and T.33. "To be really honest," Murray says, "the main reason is that 12,100 rpm in a 4.0-liter engine with valve springs is getting right up there on the ragged edge. Going to 11,100 rpm makes much more sense." Just for reference, in T.50 spec the engine makes peak power at 11,500 rpm.The other benefit is improved drivability. Murray says in T.50 spec the engine delivers 70 percent of its peak torque from just 2,500 rpm, but the T.33 version pumps out 75 percent of its peak torque at the same crank speed and 90 percent from 4,500 rpm. "I've never driven a V-12 with such low-down torque," he says of his test sessions in the T.50, "but the T.33 is on another level altogether."As in the T.50, the T.33 V-12 drives the rear wheels through a six-speed manual transmission designed and developed by British motorsport specialist Xtrac. The T.33's transmission, which weighs just 177 pounds, shares its ultralight casing with the T.50 unit, but all the internals are new.Unlike the T.50, the T.33 can be ordered with a paddle-shift transmission. Also developed by Xtrac, this transmission features the company's ingenious Instantaneous Gearchange System (IGS), which features an integrated ratchet and pawl mechanism between each gear hub and the main shaft so that two consecutive gear ratios can be selected and engaged simultaneously, but with only one set of gears driving. As there are no clutches to actuate, switching from one ratio to the next is, well, instantaneous, and there's no interruption to the torque flow.Murray says the paddle-shift T.33 will be significantly quicker than the manual car, both in a straight line and on the track, but notes that of the 60 cars already pre-sold—like the T.50, just 100 are being built—only three have so far been ordered with the IGS transmission.The T.33's chassis eschews the usual practice of bolting front and rear subframes to a central carbon-fiber tub. Instead, the car's central structure comprises Formula 1-style aluminum-core carbon-fiber panels bonded around aluminium tubes that run from front to rear. The carbon-fiber elements provide the essential torsional and bending stiffness, as well as a strong structure for crash safety, and the design eliminates the need for bolted joints."A bolted joint is messy and heavy, and it's flexible," Murray says. "No matter how well you do it, there's always a bit of joint movement at the transition from tube to carbon."Up front, supporting the suspension, steering rack, and stabilizer bar, is a single aluminum casting, which Murray won't describe in detail other than to hint it's similar in concept to the organic Bionicast structure used at the rear of the Mercedes-Benz EQXX concept. At the rear, aluminum tubes simply cradle the engine, which is attached with just four bolts. The rear suspension is bolted directly to the transmission, and although the engine is rubber-mounted to reduce noise, vibration, and harshness, a clever trapezoidal link setup is used to lock the engine and transmission into place when subjected to loads through the rear wheels.Murray reckons the innovative design of the T.33 chassis, which is loosely based on the iStream process he developed to build lightweight cars at low cost and high volume, makes it about 44 pounds lighter than a contemporary supercar chassis of a similar size. "It's taken two years to develop the technology, and we're thinking we might build the T.33 chassis ourselves to keep it in-house," he says. Like all Gordon Murray cars, the T.33 is light. Target weight is just 2,403 pounds, a mere 230 more than the T.50 despite the car being engineered to be built in both left- and right-hand drive and meeting all U.S. and European crash regulations. That means the T.33 doesn't need massive brakes, wheels, or tires. The standard brakes are carbon ceramic, with relatively modest 14.6-inch-diameter rotors in front and 13.4-inch units at the rear. The tires are relatively modest, too—235/35 Michelin Pilot Sport 4s on 19-inch forged wheels up front and 295/30 items on 20-inch wheels out back. Power steering is by way of a new hydraulically assisted system specially developed for the car.And like all Gordon Murray cars, the T.33 will have a relatively comfortable ride. "I never do stiffly sprung cars," Murray says. "I just don't like them. If you are going to drive it on a track, you're going to feel a bit of roll and pitch." However, for those customers who want to spend most of their time in their T.33s at track days, GMA will offer a sportier suspension setup. "The cars are so handbuilt, we can do virtually anything for the customers."It's difficult to judge from the photos, but the T.33 is about the same length overall as a Porsche 718 Cayman even though its roofline is 5.5 inches lower and its 107.7-inch wheelbase is an astounding 10.3 inches longer. The pictures don't show the subtlety of its design, either, the overall flavor of which has been inspired by Murray's passion for 1960s mid-engine sports cars such as the Ferrari 206 SP Dino and the Alfa Romeo 33 Stradale.The central driving position of the T.50 dictated a very cab-forward proportion. As the T.33 has a conventional driving position, which allows the pedals to be located farther rearward in the chassis, its cabin is, like those 1960s cars, more centrally located between the wheels. The wasp-waisted car also has a broad front air intake, pronounced haunches over all four wheels, and just the merest hint of a Kamm tail at the rear.The relatively clean and simple surfacing belies some truly clever design details. There are no visible door handles; access to the cabin is via touch-sensitive buttons in the Gordon Murray Automotive logos at the base of the B-pillar. The fuel and oil fillers are hidden behind the panels on the pillars. The small vent at the base of the vertically stacked headlights not only ducts air to the front brakes but also allows the car to pass low-speed crash requirements while echoing iconic 1960s headlight graphics."There's nothing just for styling's sake on the car at all," Murray says. "Every single element has something to do. "  The wide front air intake, for example, houses all the cooling hardware, which means there's no need for unsightly and un-aerodynamic ducts in the body side. Extra cooling air is ducted into the engine compartment from under the car.The ram air intake above the cabin is another case in point. While in other mid-engine cars such intakes are part of the bodywork, in the T.33 it's mounted directly to the engine and stands proud of the bodywork so it can move. That eliminates the need for a flexible coupling, which means the internals of the entire intake can be kept perfectly smooth.The other benefit, Murray explains, is more subtle: "If the intake is flush to the roof, you get a boundary layer buildup [of slow-moving air], which renders the bottom slice of the intake quite useless. By having the intake separate and floating above the car, we bleed off the boundary layer into the engine bay, which is low pressure, and then we can have a smaller, more aerodynamic duct."Although the T.33 doesn't have the downforce of the fan-forced T.50, learnings from that car have been incorporated into the floor design. Two big diffusers at the front of the car help deliver downforce to the front axle. And while testing the T.50, Murray's team found the unique stepped diffuser at the rear of the car, which had been designed to work in conjunction with the fan drawing air through it, delivered 30 percent more downforce than expected with the fan switched off.A revised version of the stepped diffuser layout is now a feature of the T.33's floor. "It was a happy accident," Murray says of the discovery. "But it means most of the downforce is developed at the front of the diffuser, near the car's center of gravity."Combined with the two-thirds total downforce developed by the front diffuser, that means the T.33 doesn't need a splitter protruding from underneath the front air intake. The only active aero device on the car is a rear wing that tilts to maintain aero balance at high speed and flicks to near vertical under braking.All this careful attention to aerodynamic detail has resulted in one very practical benefit: luggage capacity. In addition to being able to accommodate two cases in its full-width frunk, the T.33 can also carry two each in either side of the car, in compartments between the door opening and the rear wheel. To access the compartments, the entire rear quarter panels are hinged at the rear.The GMA T.50, with its central driving position and fan-forced active aerodynamics, is a trophy car, the state-of-the-hypercar-art as expressed by the man who invented the concept 30 years ago. The GMA T.33 has been designed to similarly celebrate light weight and ultimate driving thrills, but also to have the ride quality and ground clearance and luggage capacity that allows it to be driven every day."I could see myself using one all the time," says Murray, whose current daily driver is the delightful, delicate Alpine A110. "If you had to have only one supercar, the T.33 is it."There's another reason to desire a T.33, too. More V-12-powered GMA cars are coming—another two are planned over the next decade—but all will have some form of electrification to enable them to meet emissions regulations. "This will be our last nonhybrid car," Murray says. "If anybody wants the last, beautiful V-12 without any hybridization, this is the one."

The 2023 Chevrolet Colorado is a brand-new midsize pickup truck. If you're thinking, "well, that's obvious," you're right. But we do point it out because, when Chevy resurrected the previously compact Colorado as a midsize truck for 2015, it introduced a not-quite-as-new rig, a modified version of a truck it had been selling for years in global markets such as Thailand and Brazil.Alas, with a Silverado-derived frame, American-market-specific powertrains and cabin appointments, the Colorado was hardly some cobbled-together beast. The outgoing pickup is one of the best midsize pickups out there—to be accurate, it is the best, despite its age. Snatching an existing truck from Thailand proved to be such a savvy move that Ford basically did the same thing when it brought back the once-compact Ranger from the dead as a larger midsize truck—and Colorado competitor—for 2019. Given how the old Colorado was in some ways already several years old when it landed stateside eight years ago, the 2023 Colorado's ground-up newness, therefore, is one of its biggest standout features.New Is as New DoesJust looking at the new Colorado, the styling clearly benefited from this redesign. Where the old Colorado was soft-edged and fairly generic-looking, in keeping with the more budget-conscious global model, the new truck adopts a bold, assertive new look that positively screams "America, truck yeah!"Chevy moved the front axle forward, lengthening the wheelbase 3.1 inches in the process and shortening the front overhang. The net effect is a longer, more horizontal hood and improved approach angles for the nose, a boon off-road. The designers capitalized on this blocky new shape with a Silverado-like mug with slim headlights and bold inserts that give the impression of a full-width, full-height grille yawning from the bumper to the hood. (Also like on the Silverado, that mug is slightly different on nearly every trim level.) Along the body sides, there is a deeper channel cut into the door skins, which help visually puff out the squared-off fender bulges front and rear.Another big change? The previous-generation Colorado's entry-level extended-cab body style was pitched in the dustbin. You can now only purchase the Colorado as a four-door crew cab with a short bed (5-foot, 2-inch bed). Chevy says this move simplifies things on its manufacturing end, but primarily gets in line with the configuration that attracted the most buyer interest on the last Colorado. One Little Engine that CanAlso simplifying the lineup is the 2023 Colorado's move to a single engine choice. A 2.7-liter turbo I-4 engine replaces the old Colorado's entry-level 2.5-liter I-4 (which was limited to base Work Truck models anyway), 3.6-liter V-6, and 2.8-liter turbodiesel I-4 options. This engine isn't entirely new; it was introduced a few years ago on the larger Silverado 1500, and strategy-wise, it is comparable to the Ford Ranger's single, lineup-wide 2.3-liter turbo I-4 engine.Unlike the Ranger's four-cylinder, the Colorado's is available in three states of tune, offering up at least some choice. Entry-level Colorado Work Truck and LT models make 237 hp and 259 lb-ft of torque. Optional on those Colorados and standard on the Z71 and Trail Boss models is a 310-hp, 390-lb-ft version. And limited to the range-topping Colorado ZR2 (which we've covered in depth here), the ultimate off-road iteration of the new truck, is a 310-hp, 430-lb-ft 2.7-liter I-4. Chevy says that, for the most part, the power differences are achieved via tuning of the computers, though the lowest-output version has some minor hardware differences. Every Colorado mates its 2.7-liter I-4 to an updated eight-speed automatic transmission.Fuel economy estimates for the new engine are forthcoming, but the power story—both compared to the old Colorado and its primary competitors—is interesting. With 310 hp in top guise, the Colorado is the most powerful midsize pickup you can buy. Granted, the old V-6 held the same title (in both the Colorado and its GMC-badged twin, the Canyon), with 308 hp; the now-discontinued diesel engine produced a mighty 369 lb-ft of torque, but that figure's easily eclipsed by the midrange 2.7-liter I-4. Even the new base models generate nearly as much torque than the old V-6, albeit at a higher rpm (5,600 vs. 4,000). The higher-output 2.7s deliver their peak torque at just 3,000 rpm.The 2.7-liter turbo is a truck engine through and through, having been designed from the outset for duty in the full-size Silverado (and playing an unusual secondary role in the Cadillac CT4-V). In the smaller, lighter Colorado, it should prove quite burly. It also includes standard cylinder deactivation, which can shut down two cylinders under light loads. Yep, that means this'll be the only (temporarily) two-cylinder midsize pickup you can buy.Five Grades, Mostly Off-RoadEven though the Colorado comes in Work Truck, LT, Z71, new-to-Colorado Trail Boss, and hardcore ZR2 guises, all five models share key standard features, including a new (sharp-looking) 11.3-inch touchscreen with wireless Apple CarPlay and Android Auto, an 8.0-inch fully digital gauge cluster, eight bed tie downs, and a segment-exclusive electronic parking brake. Chevy says the base Work Truck and mid-grade off-road Trailboss models share a more "rugged aesthetic that is ready for work and play" inside, which we take to mean more basic, abuse-resistant, and plastickier cabin materials. The LT swaps in silver trim, plusher accents, and a leather-wrapped steering wheel, while the Z71 gets a "sportier ambiance" with black and red accents and a mix of cloth and vinyl on the seats.Again, like the newly bold exterior, the Colorado's interior goes from uninspired to competitive, with a brash, full-width dashboard panel and its round outboard air vents giving us plenty of Camaro feels. The new touchscreen perches in the middle, tombstone-style, but close to the steering wheel for what looks like a comfortable reach. There are more upmarket details throughout, though most examples—the stitching on the dashboard and padded panels around the center console—are limited to the higher trim levels. And like the Camaro, the central air vents are buried low on the dash; that pays off for the ergonomics of the climate controls, which nestle up under the touchscreen, but is probably not great for airflow above chest height for front-seat occupants. A drive mode selector lives on the left of the console on models so equipped (mostly the off-road models), pushing the shifter to the right.Other differences between the models are clearer from the outside. The Work Truck gets an all-black-plastic face like the larger Silverado WT, 17-inch steel wheels, and that's pretty much it. LT models distinguish themselves with more streetable 17-inch wheels and tires, more body color elements on the front end, and more chrome. Finally, there are the trio of off-road versions, ranging from the relatively tame Z71 to the Trail Boss (which gets a 2.0-inch suspension lift and burlier tires) to the ZR2 (which sits 3.0 inches higher than WT/LT/Z71 models and has a wider track). The grille and bumper treatments get wilder the closer to the ZR2 you get, with the ZR2 out-crazying the rest of the lineup with flared fenders, meaty bumpers, and even an available bed-mounted roll bar with lights and beadlock-capable wheels via a special-edition Desert Boss package.Off-road equipment varies from optional four-wheel-drive on the WT and LT to a standard limited-slip rear differential (standard on Z71 and Trail Boss) to power-locking front and rear diffs on the ZR2, which also once again rides on Multimatic DSSV spool-valve, frequency selective dampers. Those fancy shocks passively take the edge off the worst terrain with valving that slows faster inputs and handles slower amplitudes more softly. The net result is better wheel control over washboard surfaces and more controlled bump stop events. Ground clearance tops out at an outstanding 10.7 inches for the ZR2, with the Trail Boss standing 9.5 inches off the deck and the other Colorados perched at 7.9 to 8.9 inches.If you're thinking Chevy's inclusion of three off-road models and switch to more aggro styling and the single crew-cab bodystyle signals an intent to chase after adventurous types with the new Colorado, you're right. The automaker also hopes the new truck bed's available 110-volt household outlet, motorcycle-tire indents in the forward bed wall, and newly available in-tailgate storage will appeal to weekend warrior types. That tailgate storage, in particular, carries whiffs of the Honda Ridgeline's in-bed "trunk," an underfloor, watertight cubby with a drain that doubles as a cooler. The Colorado's lockable, weathertight hollow tailgate is less useful, probably, but at 45 inches wide and 4 inches deep can still probably be stuffed with ice and some cold snacks.If Chevy can keep the current truck's decent road manners and roomy interior in place while improving things with the new 2.7-liter engine and expanded off-road offerings, consider the 2023 Colorado a ringing success. But it'll have stiff competition: Ford is on the cusp of launching its also-all-new 2023 Ranger, and Toyota's sales-leader Tacoma is about to be redesigned, as well. We'll see how the new Colorado shakes out when it goes on sale midway through 2023.2023 Chevrolet Colorado Specifications BASE PRICE $28,000-$50,000 (est)  LAYOUT Front-engine, RWD or 4WD, 5-pass, 4-door truck ENGINE 2.7L/237-310-hp /259-430-lb-ft turbo DOHC 16-valve I-4 TRANSMISSION 8-speed auto CURB WEIGHT 4,750-5,300 lb (mfr) WHEELBASE 131.4 in L x W x H 213.0-212.7 x 84.4 x 78.8-81.9 in 0-60 MPH 7.0-7.5 sec (MT est)  EPA CITY/HWY/COMB FUEL ECON TBD  EPA RANGE, COMB TBD miles ON SALE Spring 2023 Show All

Update March 3, 2022: After just of a day of angry tweets, irate Reddit threads, and order cancellations stemming from price hikes on the original quad-motor Rivian R1S and R1Ts,  electric vehicle startup Rivian is reportedly backing off on increasing the price of its electric pickup and SUV for existing reservation holders. "Earlier this week, we announced pricing increases that broke the trust we have worked to build with you," Rivian CEO RJ Scaringe said in a letter to reservation holders and shared with the media, "We wrongly decided to make these changes apply to all future deliveries, including pre-existing configured preorders. We failed to appreciate how you viewed your configuration as price locked. "For anyone with a Rivian preorder as of the March 1 pricing announcement, your original configured price will be honored. If you canceled your preorder on or after March 1 and would like to reinstate it, we will restore your original configuration, pricing and delivery timing. Our team will be sending an email in the next few days with more details"For those who haven't yet plunked down a refundable $1,000 deposit on a Rivian R1S or R1T, the new pricing structure for dual- and quad-motor R1s detailed below applies. If you're one of the thousands who've pre-ordered or are interested in purchasing the 2022 MotorTrend Truck of the Year (not to mention the only electric vehicle to cross the Trans-America Trail), the Rivian R1T pickup, and its SUV sibling, the R1S, we have some mixed news. The good news is that the company is expanding its R1T and R1S lineup, now offering dual-motor variants and a new battery pack. The bad news is that it's going to cost more for less Rivian, as quad-motor prices rise to make room for the new two-motor versions of the R1T and R1S, which will cost the same as the entry-level quad-motors did before—at least for those who lack an existing reservation, per the update above.New Homebuilt MotorsAs we long suspected, Rivian-built dual-motor variants are now slated to join the R1 lineup. Available starting in 2024, these new Rivian designed, engineered, and built motors (one installed at each axle) are said to be good for over 600 hp and 600 lb-ft of torque, and Rivian promises a 4.0-second 0-60 mph time, making the dual motor R1T about a second slower to 60 mph than the quickest four-motor R1T we've tested. Current quad-motor Rivians produce 835 hp and 908 lb-ft of torque.Rivian also says that its new motors are simpler, lighter, and cheaper to build than the supplier-sourced motors on today's R1S and R1T.The California-based automaker isn't publicly committing to utilizing its new motors on the quad-motor R1S and R1T, but sources at the company have told us that Rivian is currently hard at work on a quad-motor R1X super SUV that makes 1,200 hp and 1,200 lb-ft. We're not math experts, but we're fairly certain that if you put four of Rivian's new motors together, the output would add up to 1,200 ponies and pound-feet.We suspect that in addition to the R1X, a detuned quad-motor R1S and R1T featuring the new motors is in the cards given CEO RJ Scaringe's desire to bring core competencies in-house.Rivian's new battery packIn addition to the new twin-motor models, Rivian today announced its new Standard battery pack will go on sale in 2024. Available only on dual-motor R1S' and R1Ts, the Standard pack joins the Large pack (on-sale now), and Max pack (slated for 2023). Dual motor R1s will be able to travel about 260 miles on a charge with the Standard pack, 320 miles with the Large pack, and over 400 miles with the Max pack, all pending EPA certification.Quad-motor R1Ts will continue to be available with only the Large and Max packs. The Large pack is the only one currently available; it nets the R1S an EPA-estimated range of 316 miles and R1T 314 miles.Price increases for the R1Although Rivian is keen to point out that base prices for the R1T and R1S remain unchanged at $68,575 and $73,575, respectively, that's a bit disingenuous, as the dual motor, standard pack is the new base configuration for the R1 line. Previously, those prices applied to quad-motor, Large pack models.Those quad-motor prices rise from $68,575 for a Large pack R1T Explore model to $80,575, and from $73,575 for a Large pack R1S Explore to $85,575. Max pack prices rise as well. The cheapest quad-motor R1T Max pack is now $90,315. The R1S, which has a shorter wheelbase than the pickup (and therefore less underbody space for batteries), is unavailable with the Max pack.Dual-motor Large pack R1Ts will begin at $74,575, and R1S' will begin at $79,575. Prices for the dual-motor R1T Max Pack start at $84,575.What does this mean for current Rivian reservation holders?Rivian chief growth officer Jiten Behl points to global supply chain shortages, increasing component parts, inflation, and semiconductor delays as the primary reason for the price changes. "This rise in cost and complexity due to these challenging circumstances necessitate an increase to the prices of the R1T and R1S models we offer today — prices which were originally set in 2018. This decision will allow us to continue to offer competitive products that maintain the high standard of quality, performance, and capabilities that our customers expect and deserve from Rivian," he said in a statement issued to the media.A source at the company initially told us that customers who are already in the final steps of completing their R1T orders won't be affected, and at the time of the March 1 announcement, unfortunately for the vast majority of existing Rivian reservation holders, the price increases were going to apply. However, given how those price changes (understandably) did not sit well with existing R1 customers and reservation holders, Rivian has made right and announced it will honor the original prices, and no doubt hopes that the new two-motor variants will cushion the blow for everyone else.
