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.

Lincoln Aviator vs Cadillac XT6 | How they compare on paper

There have been big, three-row family crossovers for quite a while now, but until recently the luxury market hasn't fully embraced them. Sure, you could literally get one with a third row, but unless you were a kid, chances are the term "dungeon-like" was going to be tossed around. Things are changing now, however, as new and redesigned entries are starting to hit the market. We've recently had a chance to get our first drives of the 2020 Lincoln Aviator and 2020 Cadillac XT6, two all-new three-row crossovers from American luxury brands. We also got a turn behind the wheel of the updated 2020 Volvo XC90. However, since none of our editors have yet to drive to drive them all, we wanted to see how they compare on paper, examining their engine specs and interior dimensions. We also included the 2020 Acura MDX, the original three-row luxury crossover, which continues to sell well despite approaching the end of its current generation. That it offers a hybrid model makes it that much more applicable given the Aviator and XC90 also offer gasoline-electric powertrains, albeit of the plug-in variety. 3 Row Luxury Crossovers Powertrains View 1 Photos Non-hybrid MDX has a 5,000-pound max tow rating. How do their performance and fuel economy compare? This one is absolutely no contest. The 400-horsepower Lincoln blows away its competitors despite having a price tag that's similar to the 310-horsepower Cadillac and in between the XC90's T5 and T6 models. At least the Acura is considerably cheaper. Besides the eye-popping output, the estimated 0-60-mph time of 5.5 seconds (gleaned from the mechanically similar Ford Explorer ST) is appreciably quicker than the others. Now, fuel economy is a bit lower, but the efficiency of Volvo's four-cylinder engines are likely more susceptible to varying due to driver differences. It should also be noted that the Cadillac gets the same combined fuel economy estimate as the Aviator despite having 90 fewer horses and 144 fewer pound-feet of torque. Just one of the ways where the XT6's prospects dim in the presence of its cross-Michigan rival. The Cadillac is also not available as a hybrid model. The others are, but are disparate. The Lincoln Aviator Grand Touring and Volvo XC90 T8 are similar in concept: range-topping models that are as much about adding performance as they are fuel economy. Their hefty price tags certainly reflect that as well.

Car and Driver 10Best list cracked by Tesla Model S, BMW 3 Series left off

Car and Driver is keeping new blood pumping into its annual 10Best cars list with three new entries making it on for 2015 and a perennial favorite falling off. Among the biggest shocks this year is that the BMW 3 Series and 4 Series are no longer named, despite years of some portion of that lineup earning a mention. In another surprise, the Tesla Model S (specifically in S 60 trim to fit under the $80,000 cost cap) makes it to the 2015 roster and is the only electrically motivated member of the group. Despite the loss of the 3 Series, BMW isn't entirely shut out this year, because the M235i gets its name on the list. Car and Driver argues that the little coupe feels like a welcome throwback to the E46 chassis M3 of the early 2000s. In addition to the Model S, the final newbie to the annual group is the 2015 Ford Mustang GT. The inclusion of these new members knocks the Audi A6/A7 family and Ford Fiesta ST out from the 2014 rundown. The other seven models carry over from last year, including the Cadillac CTS, Chevrolet Corvette Stingray, Honda Accord, Mazda3, Mazda6, Porsche Boxster/Cayman and Volkswagen Golf/GTI. The 2015 10Best cars list certainly seems to have something for everyone from the hot hatch fan to the family man and even the green car driver, thanks to the addition of the Tesla. Head over to Car and Driver to read its detailed explanations for each vehicle's inclusion, but if you've got a difference of opinion or just really like the list, let us know in Comments.
