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.

MIT puts V2V technology on its 2015 Top Ten list

Of all the technologies swimming around the automotive world, it is vehicle-to-vehicle communication that the Massachusetts Institute of Technology has fished out as one of its Ten Breakthrough Technologies of 2015. It joined emerging tech like brain organoids, supercharged photosynthesis, and Project Loon on the list, and got the nod over autonomous driving because, as the MIT Technology Review wrote, V2V communication "is likely to have a far bigger and more immediate effect on road safety." How so? Because actual cars transmitting data like their location, speed, steering angle, and state of braking to one another at least ten times per second provides a greater degree of awareness than sensor readings and algorithms. The US Department of Transportation and the National Highway Traffic Safety Administration have been working for years on standards and a regulatory schedule for introducing V2V to the marketplace, and Cadillac plans to incorporate V2V into at least one of its vehicles by 2017. Since we've begun the year with a number of stories of cars being hacked into, that got us wondering about the security of V2V communications. In a recent piece by our own Pete Bigelow on what motorists should know about getting their cars hacked into, he wrote that although cyber break-ins are extremely difficult, expensive, and time-consuming to do remotely, V2V is "one more conceivable avenue a hacker could use to impact multiple cars at a given time." So we spoke to Wilmington, Massachusetts-based Security Innovation about it. The automotive consultancy company has been working with the DOT since 2003 on V2V technology and the issues around it - namely security and privacy - and its chief scientist, William Whyte, is the technical editor of the Institute of Electrical and Electronics Engineers (IEEE) 1609.2 standard outlining its security protocols. Those protocols are expected to be finalized by the DOT toward the end of this year and then come into effect in 2016, and the company's Aerolink product is the security solution Cadillac will use. Whyte said, "If you hack into a car, V2V is the hardest place to start," and Pete Samson, the general manager of Security Innovation's automotive team, said "There are ten or 12 alternate attack surfaces" around the car that would make much easier targets.

Cadillac gives enthusiasts an early look at its next high-performance sedans

Cadillac will introduce a pair of sport sedans named CT4-V Blackwing and CT5-V Blackwing, respectively, at 7 p.m. Eastern today (February 1). While car companies routinely drum up excitement for new models by releasing tightly-cropped or blacked-out images, Cadillac surprised us with a photo, and a TV spot that aired during the Rolex 24 at Daytona, that shows both cars in their entirety. Somewhat confusingly, the CT4-V and the CT5-V are not direct replacements for the ATS-V and the CTS-V; they're mid-range models, and they're powered, equipped, and priced accordingly. It's these flagship Blackwing variants that will pick up where the last-generation Vs left off with a significant bump in power, numerous chassis tweaks, and a more aggressive-looking design. They'll arrive in showrooms in time for the 2022 model year. Blackwing drivers won't draw unnecessary attention to themselves, because the visual changes are relatively subtle. Riding on model-specific wheels, the CT4-V Blackwing gains bigger air intakes on the front end, vents punched into the fenders, and a low-key body kit that adds a front splitter, front winglets, and a trunk-mounted spoiler. Cadillac gave the CT5-V a similar treatment, and it mounted the rear wheels on surprisingly wide tires. Cadillac pointed out the Blackwing sedans benefit from the world's fastest-reacting suspension system. It's likely the fourth evolution of its magnetic ride control technology, which it detailed in October 2020.  While full specifications remain under wraps until the duo's unveiling, we know that both sedans will be available with a six-speed manual transmission. It's reasonable to assume that an automatic (likely the familiar 10-speed) will be offered as well. As for what's under the hood, our crystal ball tells us that the CT5-V will land with a V8 engine, though it won't be the short-lived twin-turbocharged Blackwing unit that gave both cars their name. Enginers might have selected an evolution of the CTS-V's 6.2-liter. As for the CT4-V, it will receive the ATS-V's 3.6-liter turbocharged V6. Both models will be exclusively available with rear-wheel-drive. Enthusiasts who want to secure an early built slot will have the chance to reserve a 2022 CT4-V Blackwing or a 2022 CT5-V Blackwing by visiting Cadillac's website shortly after the sedans are unveiled on February 1. As we previously reported, the first 250 units of each car will wear a numbered plaque on the steering wheel.
