2023 Chevrolet Corvette Z06 LT6 Engine-Tech Deep Dive: Ready, Set, Devastate
Late last year, we spent a couple hours peppering GM engineers with questions during a development drive of the 2023 Chevrolet Corvette Z06, then we interviewed a different set of engineers during a photo shoot of the car and its LT6 engine. Now Chevy has presented a 3.5-hour deep-dive webinar divulging even more of the enabling race-inspired technology behind the world's most potent naturally aspirated production-car engine. We've done our best to boil it down to 23 slides crammed full of the most essential knowledge—nuggets you'll need to explain to your pals at the pub why America's supercar has earned a place as one of history's greatest combustion-powered sports cars.

The mighty rose and fell in the auto industry in 2021. A critical shortage of microchips helped determine winners and losers in U.S. sales for the year more than any other factor. Aberration or not, the surprises are worth noting when companies deemed too-big-to-fail fall off their long-held perches and underdogs ascend to new heights.Business publications have splashed plenty of ink in the annual presentation of final U.S. auto sales as another year came to a close. We won't go all corporate and financial here at MotorTrend but there were some unexpected plot twists that deserve to be pointed out—regardless of any asterisks due to chip shortages.Toyota Topples GM For the First TimeThe biggie: after decades of U.S. sale supremacy, Toyota beat General Motors in 2021. GM sold 2.2 million vehicles, but Toyota had about 114,000 more for a total of 2.3 million.Toyota executives were quick to say the lead is not sustainable. GM will be back on top as chip supplies normalize. The semiconductor shortage hurt all automakers, but some were hit harder than others. GM and Ford were among the more heavily pummeled. Toyota was the poster child for how to—almost—survive the chip crisis.Toyota is no stranger to pinchpoints from key parts shortages. After the 2011 Tōhoku earthquake, Toyota put an early warning system in place to monitor its supply chain. The result is that the inventor of the concept of lean manufacturing and just-in-time delivery became a hoarder. Once warned, the Japanese automaker stockpiled chips and was able to keep building and selling vehicles full steam while the competition was playing whack-a-mole in determining which vehicles took priority in receiving chip rations and which plants faced temporary downtime on any given week.As the shortage stretched out and was exacerbated by a fire at the Renesas Electronics chipmaking plant in Japan, and then COVID-19 outbreaks that forced closure of facilities in southeast Asia that test and package chips, Toyota was finally forced to idle some plants. But in the end, Toyota saw 10 percent sales growth in the U.S. in 2021 while GM saw a 13 percent drop because it lost hundreds of thousands of units of production.Hyundai-Kia Leapfrogs Over HondaHyundai-Kia outsold Honda for the first time, moving up to the fifth spot with almost 1.5 million vehicles sold. That was about 22,500 more than Honda. The two brands under the Hyundai Motor Company umbrella continue to be a juggernaut. This one will be interesting to watch in 2022 because the Korean brands show no signs of slowing down and have impressive vehicles hitting the market.The Hyundai group still has work to do to catch Stellantis at just shy of 1.8 million, or Ford at almost 1.9 million.Ford EVs Coming for TeslaFord, which was considered a bit of an EV laggard until fairly recently, ended 2021 in second place when it comes to U.S. sales of electric vehicles. Credit goes to the new Mustang Mach-E; Ford sold more than 27,000 of the electric crossovers.King of the EV castle continued to be Tesla which had a banner year. How banner we don't know exactly as it the automaker does not break out U.S. sales.General Motors was out of the running in 2021, not because of the chip shortage, but because the Chevrolet Bolt was all but sidelined for much of the year by a recall due to risks of fire from bad cells in its batteries and a recommendation to park outside.Ford Mustang vs. Dodge Challenger vs. Chevy CamaroThe muscle car sales wars are legendary, and we never tire of the jostling, even though their makers don't always give them the love they once received.We have a cool toppling this year. The Dodge Challenger actually stole the title in 2021. The coupe is no spring chicken, and this wasn't a chip shortage win. Credit energetic execs behind the Dodge brand who never say die. Efforts to keep the Challenger fresh led to a 3 percent increase in sales, bringing the total to 54,314 muscle cars sold and the highest full-year share ever at 21 percent of the albeit-small segment. (Dodge Charger also grew market share to a career-best 30 percent, more testament to pixie dust being sprinkled liberally over at Dodge).That pushed the Ford Mustang to second place. A 14 percent drop resulted in a final sales tally of 52,414. For the bronze: the Chevy Camaro saw sales plummet almost 27 percent, netting 21,893 sales. The once-mighty Camaro must be missing its long-time engineer: Al "Mr. Camaro" Oppenheiser, who was reassigned to the GMC Hummer EVs and is busy crabwalking and hurtling 9,000 pounds of SUV from 0-60 in 3.0 seconds. It probably doesn't help that today's Camaro doesn't look all that different from the last one, or the one before that...Big Truck WarsNo surprises here: Ford took the title for best-selling truck in the U.S. for the 45th straight year, selling more than 726,000 F-Series. Ram came second at just under 570,000. The Chevrolet Silverado could get a needed boost from the electric version coming—the Chevy came third in 2021 with almost 520,000 U.S. sales.Who said following auto sales isn't fun?
alfa-romeo stelvio Full OverviewProsPunchy engineStrong, beautiful designFun to drive ConsSmall infotainment screenToned-down cabinTight interiorEverything sounds better in Italian, and the badge applied to the 2022 Alfa Romeo Stelvio Veloce is no exception. "Veloce" means "quick" in English, but can you imagine a vehicle called, say, the Ford Quick or the Chevy Fast? Yeah, no. Yet in Italian, the same word sounds sexy. But best of all, the Stelvio Veloce is indeed fast, sporty, and spirited.The Veloce trim came on board for the 2022 model year, replacing the Ti Sport trim. It's the highest available model with the standard turbocharged 2.0-liter four-cylinder, which happens to be the most powerful base engine in the luxury compact SUV segment.Veloce but Not Molto VeloceWith 280 hp and 306 lb-ft of torque, there's no doubt the Stelvio has guts. Step on the throttle, and the response is immediate, and full torque is on tap from just 2,000 rpm. That's among the ingredients that make the Stelvio one of the sportiest SUVs, as is the eight-speed automatic transmission that likes to hold gears when Dynamic mode is active. Even the default Natural mode is a delight, though; the transmission is relatively snappy, and the perfectly linear steering delivers a wealth of feedback. In all modes, it's possible the Stelvio might ride a little too stiffly for some, but excellent damping takes the edges off the harshest impacts, and we enjoy having a better feel for the road.Unfortunately, there's a bit of un-veloce here: Despite that muscular turbo-four, at 5.9 seconds, the Stelvio Veloce is a little bit slower than some other compact luxury SUVs to 60 mph. The time is good overall, but in our testing it trails slightly behind the 2022 Porsche Macan (5.6 seconds), 2021 Audi Q5 (5.7 seconds), and even the last Stelvio we tested—a 2018 Ti Sport (5.4 seconds). But it's ahead of the 2022 Genesis GV70 2.5T (6.0 seconds), 2021 Acura RDXand 2022 BMW X3 xDrive 30i (6.4 seconds each).But the numbers aren't the full story. Combine its responsive powertrain with its capable, composed, and confidence-inspiring chassis, and the Stelvio Veloce is, in fact, perfectly veloce. Wherever you're driving it, the Stelvio behaves more like a lifted hot hatchback, feeling quick off the line and allowing drivers to attack back roads with a zeal that makes miles disappear faster than they might in a number of more appliance-like competitors. "I like that the steering is friction free and that the rim is thin," road test editor Chris Walton said. "This allows you to steer with your fingertips and not your palms."Overall, the experience behind that wheel is engaging, and the Stevlio's personality and captivating experience are what distinguish it from the rest of the segment—and make it the target of discerning drivers who need an SUV.Gorgeous Exterior, Subpar InteriorDespite being four years old, the 2022 Alfa Romeo Stelvio Veloce remains one of the best-looking SUVs in the segment. Like its Giulia sedan stablemate, the Stelvio has aged well and continues to look sharp even when newer models have entered the market. Unfortunately, that's not the case inside. Although there isn't anything wrong with the cabin, its plain layout lacks the attention to detail and sophistication of other SUVs in the segment.The 8.8-inch touchscreen is quite small for today's standards, and although we like its functionality and placement in the center console, the infotainment system feels antiquated and lacks updated graphics. There is no wireless Apple CarPlay or Android Auto, and it's a bit hard to explore or find what you need given the limited menu buttons.The rest of the cabin lacks the plushness we've seen in other SUVs, as well. There's nothing that will grab the attention of anyone getting into a Stelvio for the first time. The ergonomics are perfectly fine, with everything within reach of the driver, and there are hard buttons for the A/C and a volume knob, but designers missed an opportunity to make the interior more elegant and premium. In addition, interior space is a bit tight for those in the rear seats, with a big drivetrain hump that will make middle-seat passengers uncomfortable.If Alfa was aiming for a simplistic, driver-focused cabin that wouldn't draw attention from the sensational driving experience, then we suppose the layout, design, and technology make sense. But when compared against other compact luxury SUVs, the Stelvio stands out for lacking content important to buyers these days. Ventilated seats, for example, aren't an option on the Veloce, and some safety technologies standard in other SUVs (like lane keep assist) are part of a $1,495 package here. Given the excellence permeating the segment from the likes of, say, Genesis, Alfa would do well to up its game.Although lane keep assist is an option, the Veloce adds several driver assist features that were previously optional. Adaptive cruise control, blind-spot monitoring, lane departure warning, automatic high-beams, and front and rear parking sensors are now standard. Navigation, wireless charging, and heated front and rear seats are also included on all trims.Should You Buy a 2022 Alfa Romeo Stelvio Veloce?If you're looking for a sporty experience, an attractive design, and a cabin that delivers the basics, then the answer is assolutamente sì. But if you'd rather drive an SUV that focuses on comfort and interior amenities, there are better options.The 2022 Alfa Romeo Stelvio Veloce we tested checked out at $60,665, on the expensive side of the ledger. Compare that with the $64,670 of our long-term 2022 Genesis GV70 Sport Prestige with the optional 3.5-liter turbo V-6 engine, and the Stelvio suddenly feels short on value. The GV70 does a better job delivering a plush cabin with lots of attention to detail and premium materials, and it still feels sporty without sacrificing ride comfort.And yet, for a model that's only received light updates since it came out in 2018, the Stelvio is aging gracefully. It falls short in many objective areas, but every opportunity to drive it is another opportunity for fun, and that's high on our list of priorities. If it's high on yours, too, you'll likely think the Stelvio is simply spettacolare.Looks good!

It's finally happening: The iconic Meyers Manx is being reborn for a third time, now as a pure electric vehicle. No, it's not the ID Buggy concept Volkswagen cruelly teased us with a few years ago before crushing our dreams, it's an all-new model from the original outfit. Meet the Meyers Manx 2.0 Electric.Real DealLest you think this is another one of those startups that has nothing to do with the original, the EV dune buggy is being produced in California by the Meyers Manx company in partnership with "a U.S.-based manufacturing entity." Manx fans will know that founder Bruce Meyers died in February 2021 at age 94, and a year prior had sold his eponymous company to Trousdale Ventures to ensure its continuation after his passing. Trousdale founder and Meyers Manx chairman Phillip Sarofim hired legendary car designer Freeman Thomas, who penned the Volkswagen New Beetle among other notable projects, to create this next-generation Manx EV.Thomas' work is refreshingly true to the original while incorporating modern components and working around a wildly different drivetrain. Even so, it likely has more in common with the original Manx than the later models you know. The first Manx featured a custom fiberglass monocoque body with embedded steel mounting points and reinforcements. Too expensive to mass produce, Meyers switched to using a shortened Volkswagen Beetle platform with a fiberglass body after 12 unprofitable cars were built.Small Battery, Lightweight, And Plenty Of RangeThis new model utilizes an aluminum monocoque covered with a body made of an unspecified material. Indeed, a number of technical details are unclear or unannounced at this time. Regardless, hidden somewhere under the retro body work is a choice of two battery packs, one 20 kWh and one 40 kWh. Those are small by EV standards, but unlike a Tesla, the Manx 2.0 Electric only weighs an estimated 1,500 to 1,650 pounds depending on battery size.Thanks to its low weight, Meyers Manx estimates the buggy will go 150 miles with the small battery and 300 miles with the big battery. A Level 2 (6 kW) onboard charger is standard and DC Fast charging capability is optional, though only at 60 kW. Here again, the stats are unimpressive for a road-going EV, but the Manx 2.0 Electric's batteries are so small they shouldn't take too long to charge even at those speeds. We can't say for sure, though, because the company has not shared charging times.Regardless of battery size, power will be sent to a pair of electric motors mounted on the rear axle, one driving each rear wheel for precise traction control and torque vectoring. Meyers Manx doesn't have specs on the motors paired with the smaller 40 kWh battery but says that model buggy will hit 60 mph in an estimated 4.5 seconds. Go for the big battery and the motors will put out 202 horsepower and "up to" 240 pound-feet of torque. The company didn't provide a zero-to-60 estimate for that model but it'll certainly be quicker.Ready To Go Off-RoadLike the original, the Manx 2.0 Electric will feature independent front and rear suspension, but we don't have any details on the design used. Photos indicate a trailing arm front suspension like the original air-cooled Beetles and the original Manx. The rear, however, appears to be a modern multi-link design rather than old swing arm setup. Both look to have plenty of travel as an off-roader should, but the company hasn't provided those specs or official ground clearance.Unlike the old Beetle-based kit car, this new one features disc brakes all around instead of drums and also adds regenerative braking on the rear axle, not to mention an electric parking brake. Up front, the Manx 2.0 Electric gets electric power steering and even windshield wipers.In all the most important ways, though, it's true to the original. It's rear-wheel drive, has knobby off-road tires, seats two, and the roof comes off. Inside, the seats appear to be wrapped in a vintage tweed pattern and the minimalist dashboard features a single retro-modern round gauge. The roof appears to be one piece that lifts off the car and gets left in the garage. Like the old days, there are no doors. We hope there's more lockable storage in the front and rear now that there's no engine or gas tank in those spots.No Price Yet, But You Can Be An Early AdopterThe biggest unanswered question we have is what the price tag will be for this adult-sized beach toy. Meyers Manx says they haven't set one yet, but if you don't care and want to get your name on the list now, reservations will open on the company's website after the car's public debut at The Quail show on Friday, August 19, during Monterey Car Week. Deliveries will begin in 2024.If you want to be a real early adopter, though, 50 buyers will be selected to participate in a beta program in 2023. In return for special access, you have to agree to provide feedback to the company while they work out the final kinks before full production begins.
