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.

Chevy up to old EVs-equal-range-anxiety tricks in new Volt Olympics ad

General Motors is at it again with a new Chevrolet Volt TV commercial. Viewers of the Winter Olymics (at least in some markets) recently saw a TV ad in between the skating and the skiing that made no mention of the environmental benefits or freedom from the power of Big Oil that electric vehicles provide. No, this one was based on pure survival instinct. In the video, a father is driving down a highway, perhaps through the Mojave Desert. His young son is sitting in the Volt's backseat and asks what happens when the EV's battery runs out. "We'll have to cross that burning desert with snakes and cactus until we make it back to civilization," the dad tells his son as they pass the skeleton of a fallen bull. The fine print makes it clear that the actual maximum range is 342 miles. But there is hope. The father tells his son, with a beaming smile on his face, that the gas generator has kicked in and they're going to make it through the desert. As they wend their way to the horizon, a voice over says that Volt drivers who charge up regularly are making it 900 miles between fill ups. The fine print makes it clear that the actual official maximum range before you need to either plug in or fill up is 342 miles. This theme that emphasized range anxiety has been utilized by GM since the extended range Volt was launched in late 2010, despite the fact that Chevrolet now offers an all-electric vehicle in the Spark EV. Volt fans are praising the commercial, called The New Freedom, on the GM-Volt forum and you can see for yourself below. This content is hosted by a third party.
