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 rolls out Silverado HD High Country

It's been a good week for heavy-duty truck buyers. First, Ram revealed the Black Package for its HD trucks, then it rolled out its new Power Wagon, and now Chevy's getting in on the action with its Silverado High Country HD. Okay, so it may not pack quite the attitude of Ram's latest 2500-series offerings, but the High Country HD will come as a welcome addition to the Chevy Trucks range to those looking to pull their horse, boat or other trailer without skimping on creature comforts.
Rolled out a little under a year ago, the High Country trim is Chevy's answer to the likes of the GMC Denali, Ford King Ranch and Ram Longhorn. It has until now only been offered on the light duty, 1500-series Silverado, but now extends to the 2500 and 3500-series HD models, as well.
So what sets a High Country pickup apart from lesser Chevy trucks? You'll be able to pick it out based on its chrome horizontal grille, body-color bumpers, 6-inch tubular side steps, 20-inch chrome wheels (18-inch on the 3500 and 17-inch on the dualie) and, of course, plenty of special badging. But it's inside where the High Country makes its mark, with a cabin decked out in saddle brown perforated leather, seats that are both heated and cooled, eight-inch touchscreen with full MyLink suite, Bose audio and park assist functions front and rear to keep those color-keyed bumpers looking fresh. (Though Chevy hasn't yet showed us the interior of the HD model, it'll presumably look mostly the same as the cab in the 1500 High Country in the gallery below.)

General Motors shaking up its marketing... again

One of the things that dogs the full comeback of General Motors is the instability of its marketing. That part of the automaker got yet another big shakeup today when GM confirmed what I have been tweeting for a few days - strong rumors that the Chevrolet and Cadillac ad accounts are walking to new ad agencies.
Cadillac, GM's luxury brand, is going into review from Fallon Worldwide, Minneapolis and the indications are that Campbell-Ewald, Chevy's old ad shop, will end up with most or all of it. C-E just announced that it was moving from its long-time home in Warren, MI to a new downtown Detroit office next to Ford Field, just blocks from GM.
The other shoe to drop shortly will be the shift of GM's most important brand, Chevy, from Goodby, Silverstein & Partners of San Francisco to McCann-Erickson of Troy, MI. McCann used to be the agency for Buick and GMC, as well as GM's corporate advertising, and has retained some pieces of business over the last few years. Sources have even told us that it was McCann that did a lot of the creative work on Chevy's new ad platform, Find New Roads. (Not to be confused with a former McCann tagline for Saab, "Find Your Own Road.")
