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.

Cadillac's Blackwing V8 was the best engine at the worst time

It should be clear that GM knows how to innovate and engineer excellent products when it wants to. Cadillac's 4.2-liter twin-turbo Blackwing V8 is recent proof of that. Yet, as related in an extensive Road & Track piece, the Blackwing became victim to some of The General's bugbears, like the reticence to — for whatever reasons — unleash its excellence everywhere, fund that excellence, and be consistent with that excellence over the long term beyond the Corvette and full-sized pickups and SUVs. The R/T story relates tales told by "several people deeply involved with the Blackwing project" about how an engine 18 years in the making was deprived of its reasons for being in less than three. Starting around 2000, GM spent a dozen years building Cadillac up to the point where the American luxury brand could rationally flip to the chapter called, "Taking the Fight to the Germans, but for Real this Time." The first steps in the plan meant an exclusive platform and an exclusive engine. The platform was called Omega. You know the engine's name. They were going to be the aluminum-blocked fist and velvet glove enabling Cadillac to break on through to the other side of luxury — proper luxury to global standards, that is — with a range of beautiful and dynamic crossovers and sedans. An engineer involved in the project estimates GM poured $16 million into the Blackwing's clean-sheet development. Many more seven-figure sums went into creating the first sedan on the Omega platform, the CT6. The automaker dropped millions again poaching ex-Audi and Infiniti chief Johan de Nysschen, and moving Cadillac's headquarters to New York City in 2014. Further pallets of cash funded the development and debut of the Escala concept at Pebble Beach in 2016. In 2018, GM revealed its dramatically named DOHC twin-turbo V8. Considering what came before, the Blackwing clearly wasn't designed for cars. It was designed for world domination. However, against the backdrop of plummeting sedan sales, the CT6 didn't sell like GM had hoped. The automaker hesitated to marshal another fleet of Brinks trucks to fund entries into a cratering bodystyle. Removing sedans from the world domination equation created more difficult math for the crossovers and the Escala.

2020 Chevy Tahoe High Country spied along with next-gen Escalade

Have no fear, the big grilles are here. Or, at least we think they're coming. One of our spy shooters caught the next-gen Chevrolet Tahoe and Cadillac Escalade out testing with more of their fronts ends exposed than before. Starting with the Tahoe, we can see what amounts to a blinding amount of chrome under the wrappings. We're guessing this would be a new Tahoe High Country trim level, mirroring the range-topping trim level currently offered on the Silverado and Traverse. The Tahoe's current range topper is the Premier. Although the rather ornate details in the grille are not found on the current High Country trims, they also seem like something that would be available on the priciest Tahoe available. The same could be said of the LED lighting details visible under the camo as the Silverado High Country, shown below, does indeed have unique LED elements. The next-generation Cadillac Escalade only shows up in two of the photos. As we can't see shiny chrome reflecting through the camo, we're guessing the Escalade will adopt a blacked out grille similar those found on the XT6 and other Cadillacs. We can also see horizontal lighting elements similar to those on other recent Cadillacs. As this is an Escalade, however, we'd imagine everything will be supersized. GM will be ushering these trucks out soon, with the independent rear suspension being the big story. Besides the improved ride and handling, it should result in substantially improved cargo space and third-row legroom. Doing so would at least close the gap with the biggest Lincoln and Ford SUVs.
