Watch how Corvette Racing's new collision-avoidance radar system works

When it comes to technology used in racecars, we generally expect it to trickle down to production cars, not the other way around. Well, Pratt & Miller has developed a new rear-facing radar that operates in a similar fashion to what we're used to in modern blind spot detection systems, only it is also capable of tracking cars as they approach and relaying vital information to the driver via a large display screen.
The innovative radar system debuted at last weekend's 12 Hours of Sebring for Corvette Racing, and this system makes perfect sense for endurance races like this since the cars sometimes have to drive through the night and in poor weather conditions.
The radar can detect cars even with poor visibility, and uses easy-to-distinguish symbols for the driver to identify.

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.

2014 Chevrolet Corvette Stingray priced from $51,995*

After months of speculation, Chevrolet has finally revealed the official starting price of the 2014 Corvette Stingray. The base MSRP for the 450-horsepower Stingray Coupe will be $51,995, while the Stingray Convertible will go for $56,995 (*both prices include a $995 destination fee). This means that the price increase from 2013 to 2014 is just $1,400 for the coupe and $2,395 for the convertible - pretty modest increases considering the upgrade in specifications. Of course, neither price accounts for the sort of dealer markup that might grace early C7 window stickers, especially since less than a third of all Chevrolet dealers will be allocated Corvette models to sell at the car's launch.
Now, these prices are for the base car, so if you're wondering how much a fully loaded Stingray will run, Chevy has given us a good indication of that as well. The coupe we saw on display at the Detroit Auto Show (shown above), for example, would run $73,360 including options such as the $2,800 Z51 Performance Package, $2,495 competition sport seats and the $1,795 Magnetic Ride Control option - just to name a few. Stepping up to the 3LT trim level that brings a full leather interior will run an extra $8,005 over the base price.
While $20,000 in options may seem like a lot, this "as-tested" price still has the C7 competitively priced against rival coupes like the Porsche 911 and Nissan GT-R. Speaking of price comparisons, Chevrolet also points out that the C7 Stingray Z51 costs $2,200 less than the C6 Grand Sport while delivering better acceleration (0-60 mph in less than four seconds) and improved track performance (including more than 1 g in cornering).
