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 extending warranties on Cadillac CTS-V and Chevy Camaro ZL1 for supercharger issue

Okay General Motors, we've sat by and watched you recall the compact cars, crossovers and pickup trucks, and aside from reporting on it, we've been fairly quiet. This, though, this will not do. We can almost tolerate the recalls on the bread-and-butter cars, but leave the performance vehicles alone.
According to a report from The Car Connection, GM has discovered a problem with the superchargers of the 6.2-liter V8s found in the Chevrolet Camaro ZL1 and the Cadillac CTS-V. Apparently, the issue rests around the internal bearing shaft grease, which can become contaminated (we aren't sure with what). If left unchecked, it'll first lead to a rattle at idle, which goes away under slight throttle. The real warning stage is when a high-pitched squeal develops, signaling that the bearing shaft has failed. Naturally, severe engine damage is the next step (although it's possible that the engine will also just refuse to turnover, although neither case is desirable).
According to TCC, GM will replace the superchargers on vehicles that have exhibited symptoms of bearing shaft failure free of charge. It will also, allegedly, be extending the warranty on all supercharged ZL1s and CTS-Vs to 10 years or 120,000 miles (whichever comes first), from the date of purchase. Officially, only 2009 to 2013 CTS-Vs and 2012 to 2013 ZL1s are suffering from this issue.

2020 Cadillac CT5 loses the fake scoop

Well folks, the inevitable has happened. The 2020 Cadillac CT5 luxury sports sedan prototype has shed its hood scoop. Yes, we're as disappointed as you are that instead of being outrageous and brash, Cadillac is still going to try to be classy, understated and luxurious when it comes to its mainline models. And yes, we're being sarcastic here ... but there's a part of us that would kind of like to see the scoop survive. Anyway, the good news is that the scoop is only one of a few bits of fake bodywork and camouflage that the CT5 has shed. As such, we get our best look yet at the new Cadillac sedan, and it looks pretty good. The grille is very wide and not nearly as tall as the prominent prows of current Cadillacs. It actually doesn't even look as tall as the grille of the Escala concept that inspired the CT5's design. The profile of the CT5 isn't too radically different from existing Caddies, with a long hood and a short trunk. It is still a conventional sedan, though, and not a sedan-like hatchback like the Kia Stinger and Audi A5 Sportback and A7. This is evident by the open trunk lid our spy photographer caught. The taillights also continue to be slim and vertical, though we can't quite tell if they will have a horizontal elements at the bottom like on the XTS and XT4. The car also has very bold and thick angular exhaust tips. We expect the CT5 will go into production in 2019 as a 2020 model, and it will likely take the place of both the CTS and ATS, but not be much smaller than the CTS. It will likely use versions of existing Cadillac engines including the 2.0-liter turbo four-cylinder, naturally aspirated 3.6-liter V6, and twin-turbo 3.0-liter V6. We wouldn't rule out the 4.2-liter twin-turbo V8 for a potential CT5-V in the future. Related Video:
