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.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.

Chevrolet Chaparral 2X Vision Gran Turismo could only work in a video game [w/video]

There's something wondrous about the Vision Gran Turismo series of concepts that has let companies go wild with completely imaginary concepts for Gran Turismo. For Chevrolet's crack at the idea, it has taken a page out of its performance past with the Chaparral Can-Am racers of the '60s and '70s, with its designers having reinterpreted that period look for the future of motorsports as the Chaparral 2X. In real life, the 2X looks even better than in earlier photos. The design takes inspiration from someone in a flying suit with head down and arms outstretched, an influence you can really see that in the vehicle's shape. The driver lies facedown inside with the instruments projected onto a visor. Unfortunately, the powertrain here is a complete flight of fancy and works purely in the video game world. It imagines a laser propelled by lithium-ion batteries and an air-powered generation to make 900 horsepower. The 2X has a theoretical top speed of 240 miles per hour and hits 60 mph in a lightning-quick 1.5 seconds. Scroll down to see the concept on video with Chevrolet designers describing their inspiration and read the company's full announcement. It's also downloadable in Gran Turismo 6. Chevrolet to Show Chaparral Vision Gran Turismo Concept Boundary-pushing, Chevy-powered race cars changed motorsports design DETROIT – When racers Jim Hall and Hap Sharp founded Chaparral Cars in 1962, few could have guessed how they would shake up the conformities of the racing world – and fundamentally change it. Through pioneering applications of aerodynamics and aerospace technology, and a partnership with Chevrolet Research and Development, Chaparral Cars advanced the science of racing cars. It also triumphed on the track over well-established sports car companies from around the world, using Chevrolet horsepower. It was that spirit of innovation that inspired the Chevrolet Chaparral 2X VGT concept race car developed for the Vision Gran Turismo project, which celebrates the 15th anniversary of PlayStation® racing game Gran Turismo by inviting manufacturers to give fans a glimpse into the future of automotive design. It will debut at the Los Angeles Auto Show, Nov. 19, and gamers will be able race the Chaparral 2X VGT following the release of an online update for Gran Turismo 6 during the holiday season.
