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.

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).

Chevy Volt owners log half a billion electric miles, 2015 production starts

As General Motors gets ready to start 2015 Volt production Monday, Chevrolet is looking back at some of the numbers that got the car to where it is today. The headline number is that Volt owners have collectively put more than a half-billion electric miles on their cars. The unsurprising upshot is that, if you went out and bought a Volt, you're pretty keen on getting as many electric miles out of it as possible. 90 percent of all Volt trips are done purely on electric power. The typical Volt driver goes 970 miles between fill-ups, GM says, and that means that 63 percent of all miles are done on battery power. General Motors executive director Larry Nitz gave AutoblogGreen a few more details on the usage habits of Volt drivers, including that 81 percent of commuting miles are electric. Two-thirds of US Volt drivers charge their vehicle 1.4 times a day, a clear indicator of drivers trying to maximize electric miles through opportunity charging. In fact, Nitz said, 90 percent of all Volt trips are done purely on electric power. GM also says that the Volt's official 35 miles of electric range is still doable for many owners who have had their car for more than 30 months. Looking ahead, we know that one upgrade for the 2015 Volt will be 4G LTE connectivity that can turn the car, like others in the GM family, into a mobile wifi hotspot. We're of course much more interested in when GM is finally going to start production of the next-gen Volt, but GM officials would only tell us that they're very excited about the still-secret vehicle, promising we'll be learning more "soon." Nitz did confirm that today's Volt drivers are most interested in three things from the next-gen model: more range, a lower price and a fifth seat. He did not say whether or not GM will be able to deliver on those requests. Chevrolet Volt Owners Surpass Half a Billion Electric Miles After 30 months of use, a sampling of Volts shows consistent all-electric range 2014-06-19 DETROIT – Since its launch in late 2010, Chevrolet Volt owners have accumulated more than half a billion all-electric miles. Additionally, based on a General Motors' study of more than 300 Volts in service in California for more than 30 months, many owners are exceeding the EPA-rated label of 35 miles of EV range per full charge, with about 15 percent surpassing 40 miles of range.
