Experimental mid-engine XP-819 Corvette going up for auction

It seems to be commonplace that when a new Corvette is in development, rumors swirl about a possible mid-engine layout. As is the case of Chevy's most recent C7 Corvette, these rumors never pan out.
In any case, the idea for a 'Vette with an engine mounted behind the driver can probably all be traced back to a single car, the 1964 XP-819 prototype. Built as an "engineering exercise" back in 1964, the prototype was designed with a rear-mounted engine. History tells us that the idea of a rear-engine Corvette fizzled, and the XP-819 was eventually cut up into pieces and stored at a shop in Daytona Beach, FL.
After sitting for untold years, a restoration project started on the car, and while it isn't yet fully completed, the current owner of the car, Mid America Motorworks, will have the car on display at the 2013 Amelia Island Concours d'Elegance as a "driveable chassis" with hopes of having a fully completed car ready to bring to next year's show.

Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.

These cars are headed to the Great Crusher In The Sky

It happens every year. We bid adieu to some cars and trucks that will be missed, and say good riddance to others wondering how they stayed around so long. Whether they're being killed off for slow sales or due to a new product coming along to replace them, the list of vehicles being discontinued after 2012 is surprisingly long and diverse.
CNN Money has compiled a list of departing vehicles, to which we've added a few more of our own. In the slow sales column, cars like the Lexus HS 250h, Mercedes-Benz R-Class and the full Maybach lineup appear, while the Ford Escape Hybrid, Mazda CX-7 and Hyundai Veracruz are all having their gaps filled with more modern and more fuel-efficient alternatives. Obvious exceptions to the rule include models that still sell in decent numbers like the Jeep Liberty and the Chrysler Town & Country (which will eventually be replaced by a crossover-like vehicle).
