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 Chevy Cruze Diesel arrives with 42 mpg for $25,695*

The last time General Motors had a diesel passenger car in the US, it was the 1.8-liter 1986 Chevette. At the 2013 Chicago Auto Show today, GM is unveiling the much-anticipated 2014 Chevrolet Cruze Diesel. The compact bows with a 2.0-liter turbo-diesel four-cylinder engine that boasts 148 horsepower and 258 pound-feet of torque, with full twist coming on at just 2,000 rpm. What's more, the common-rail, direct-injection diesel features an overboost function that allows the engine to deliver up to 280 lb-ft of torque for 10 seconds at a time. Even with 10 more horsepower and 110 more pound-feet of torque than the available turbocharged 1.4-liter four-cylinder in the Cruze, the 2.0-liter diesel engine can return up to 42 mpg (highway) bolted to its six-speed automatic transmission.
If you're counting, that figure meets the less powerful Cruze Eco with a six-speed manual transmission. More importantly, the auto transmission Cruze Diesel matches its main competition, the Volkswagen Jetta TDI, in highway fuel economy. The Cruze 2.0 TD (as it will be badged) can also handle up to 20 percent biodiesel (B20), whereas the Jetta is rated only for B5. General Motors has not released city fuel economy for its newest diesel, but we do know how much it will cost you to jump behind the driver's seat.
GM will kindly ask for $25,695, plus an $810 destination fee. That marks a $2,115 premium over a loaded Cruze LTZ Auto and $2,640 more than the Jetta TDI, though the MSRP will net you a leather interior, 17-inch alloy wheels and an Aero Performance Package, as well as a two-year maintenance plan and five-year, 100,000-mile powertrain warranty. Compared to the gas-powered Cruze, you also lose a couple cubic feet of rear cargo space thanks to a 17-liter diesel emission fluid tank. That urea fluid, which helps put the clean in clean diesel, will need to be refilled at least every 10,000 miles.

Why the Corvette is Chevrolet's billion-dollar baby

Edmunds has worked up a piece that tries to figure out just how much the global Chevrolet Corvette economy is worth, a spitballed guesstimate putting the number at more than $2.5 billion with the proviso that the number is probably low. It starts by taking Corvette's new car sales of 14,132 units last year, which would equate to $714,725,900 (including destination) assuming ever car sold was a base coupe with no options. In the final tally, a little extra padding gets that number up to $750,000,000.
But that's not all. Consider this: Many of the almost 1.4 million Corvettes produced over the model's history are still on the road. There are new parts being produced and aftermarket companies like Mid-America Motorworks deaing business, that single Illinois company doing more than $40 million a year in sales. There are the Corvette events large and small, restorers who do nothing but Corvettes, salvage yards that deal only in used Corvette parts and the Corvette magazines where owners find all this stuff.
And then there are the Corvette-themed tchotchkes, every single one of which provides a tiny contribution to the huge licensing royalties that General Motors collects every year. The article admits there's no way to come to an accurate number, but it just goes to show how valuable one specific model can be to a company.
