VW, Rivian, Nissan, BMW, Genesis, Audi and Volvo lose EV tax credits starting tomorrow

The U.S. Treasury said Monday that Volkswagen, BMW, Nissan, Rivian, Hyundai and Volvo electric vehicles will lose access to a $7,500 tax credit under new battery sourcing rules. The Treasury said the new requirements effective Tuesday will also cut by half credits for the Tesla Model 3 Standard Range Rear Wheel Drive to $3,750 but other Tesla models will retain the full $7,500 credit. Vehicles losing credits Tuesday are the BMW 330e, BMW X5 xDrive45e, Genesis Electrified GV70, Nissan Leaf , Rivian R1S and R1T, Volkswagen ID.4 as well as the plug-in hybrid electric Audi Q5 TFSI e Quattro and plug-in hybrid (PHEV) electric Volvo S60. The Swedish carmaker is 82%-owned by China’s Zhejiang Geely Holding Group. The rules are aimed at weaning the United States off dependence on China for EV battery supply chains and are part of President Joe Biden's effort to make 50% of U.S. new vehicle sales by 2030 EVs or PHEVs. Hyundai said in a statement it was committed to its long-range EV plans and that it "will utilize key provisions in the Inflation Reduction Act to accelerate the transition to electrification." Rivian declined to comment and the other automakers could not immediately be reached for comment. Treasury also disclosed General Motors electric Chevrolet Bolt and Bolt EUV will qualify for the full $7,500 tax credit. GM said earlier it expected at least some of its EVS would qualify for the $7,500 tax credit under the new rules, including the 2023 Cadillac Lyriq and forthcoming Chevrolet Equinox EV SUV and Blazer EV SUV. Treasury said all GM EVs will qualify. Earlier, Ford Motor and Chrysler-parent Stellantis said most of their electric and PHEV models would see tax credits halved to $3,750 on April 18. Treasury confirmed the automakers' calculations. The rules were announced last month and mandated by Congress in August as part of the $430 billion Inflation Reduction Act (IRA). The IRA requires 50% of the value of battery components be produced or assembled in North America to qualify for $3,750, and 40% of the value of critical minerals sourced from the United States or a free trade partner for a $3,750 credit. The law required vehicles to be assembled in North America to qualify for any tax credits, which in August eliminated nearly 70% of eligible models and on Jan. 1 new price caps and limits on buyers income took effect.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Our favorite mid-engine Corvette theories and rumors

The mid-engine Corvette! We just saw blurry photos through the foliage, and are hearts are all aflutter because it means that this car is real. And it's the most " never before" Corvette since 1984. Which leads us to all kinds of wacky theories and speculation. Everybody knows something or heard from a guy. None of those guys (or gals) from GM are talking to Autoblog, to be clear. But that won't stop us from stirring the pot. Let's go over a few point-by-point. The pushrod engine will be replaced by an overhead-cam V8 Car and Driver has repeatedly reported that an overhead-cam engine will come after the mid-engine Corvette's debut with an old-school pushrod. We've heard the same thing firsthand, albeit from a source with no connection to the development of the Corvette or powertrain. "At some point two valves can't pass future emissions regulations," said the guy we know. While the pushrod engine is compact, the design makes it difficult - if not impossible - for sophisticated variable valve timing (and lift) systems that control combustion with more precision. Hasty conclusion: The pushrod engine has a finite life in front of it. This one's a lock, it's a just a matter of when. Bowling Green's new paint shop is really the mid-engine assembly line Credit to Reddit for this one. Like we said, everybody knows a guy. But let's look deeper. The new paint facility costs $439 million dollars and adds 450,000 square feet, almost half the size of the existing plant. Plus GM announced another $290 million in upgrades at Bowling Green Assembly. That sure sounds like a lot of money, but you can actually spend that much on a paint booth. Porsche spent 500 million Euros (about $561 million dollars) to add the Macan assembly to its Leipzig, Germany plant in 2014. Chrysler shelled out $850 million for a paint shop in Sterling Heights, Michigan. GM spent $600 million for a new paint shop at the Fairfax (Kansas City) plant. Honda, on the other hand, is working on a thrifty $210 million project in Marysville, Ohio that includes a 300,000 square foot expansion, and the low-volume Acura NSX facility only cost $70 million. Hasty conclusion: The square footage and cost could easily mean a new assembly line instead of (or in addition to) a paint line. And if the NSX plant was really that cheap, GM could have hidden a similar sum in its existing announcements.
