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.

GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.

Expect the Cadillac XT3 small crossover in late 2018

Cadillac's sedan-heavy lineup can't complete in this crossover-crazy market, it seems. The Detroit News spoke to Cadillac boss Johan de Nysschen and found out some more details about the brand's plan to alter its lineup to cater more to current consumer tastes. It's no surprise that these plans would include a small crossover, because de Nysschen has been talking about a vehicle smaller than the XT5 like this since at least 2015. The report also pins the Fairfax Assembly Plant, where GM builds the Buick LaCrosse and the Chevrolet Malibu, as the site for what could be called the XT3's production. That's not an immediately obvious choice, since the LaCrosse and Malibu are based on the latest evolution of the Epsilon platform, known as E2XX. And the XT5 is based on a crossover version of that same platform (known as C2XX), while XT3 is expected to be smaller than the XT5. So perhaps there's a different assembly line going into Fairfax, or the C2XX platform can be significantly shortened. We assume that the XT3 would be built on a smaller platform, perhaps the Gamma II that underpins the Chevrolet Trax and Buick Encore – which are built in either South Korea or Mexico, depending on which market they are to be exported to. The Encore is selling very well for Buick, with sales figures increasing through late last year. Another possibility is the D2XX platform that underpins the Chinese-built Buick Envision and the GMC Terrain and Chevrolet Equinox, perhaps with assembly happening at the CAMI plant in Ontario. At this early stage, without confirmation of GM as to what platform the XT3 will use or where it will really be built, it's too early to say what the Fairfax rumor means. This isn't the first time we've heard about a small Cadillac crossover. Back in 2015, de Nysschen told us to expect it sometime in 2018. But later that year, speaking to Reuters, he posited that it'd be closer to 2019. The Detroit News says de Nysschen told them it'll launch in the second half of 2018, splitting the difference between what we'd heard previously. Remember, Cadillac's only two vehicles in the segment are the XT5 and Escalade. We know that the brand is almost certainly scrambling to fill the holes in that side of the lineup. We think a three-row crossover will slot between the two, probably called the XT7.
