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.

GM profits threatened by glut of pickups

Automotive News reports that General Motors may slash production or ramp up discounts in order to deal with an oversupply of pickup trucks. GM currently has more than double the standard supply of pickups, and the vehicles are threatening to dampen the automaker's profits for 2013. Typically, automakers try to sustain a 60- to 75-day supply of vehicles, but GM is currently loaded with a 139-day supply, as of last month. At the end of November, the automaker was sitting on 245,853 units.
The manufacturer says that it will adjust production accordingly before laying any incentives on the profitable pickups. Even so, there's some concern that the inventory swell could hurt the roll-out of the next-generation Chevrolet Silverado and GMC Sierra. GM actually began slowly stepping back production in August, but it's clear the company will take further action as it heads toward the end of the year and into the next. Analysts predict the automaker could reduce pickup manufacturing by nearly half in the first quarter of 2013.
That still may not be enough to keep GM from laying extra cash on the Silverado and GMC Sierra. While the company's incentive spending was down in November compared to the same month in 2011, both the Ram 1500 and Ford F-150 saw double-digit percentage increases in sales last month while the Silverado and Sierra numbers slid compared to a year prior. Incentive spending could help move more trucks and add some balance to the GM inventory surge.

Pure Vision Design TT Camaro has 1,400 reasons to want it

We've talked about Pure Vision Design before, a California-based company that made waves at last year's SEMA show with its Martini-liveried, Indy-car-powered Ford Mustang. That same car later starred in a Petrolicious video we showed you just a few weeks back. The company's latest creation is a menacing car it calls the Pure Vision Design TT Camaro. Based on a 1972 model, this car shares the Martini Mustang's clean styling and obsession with details.
Unlike the Mustang, which draws its power from a mid-60s Lotus-Ford Indycar engine, the "TT" in this Camaro's name implies something far more potent. The Nelson Racing Engines 427-cubic-inch V8 has been fitted with a pair of turbochargers, with a claimed output of 1,400 horsepower. That's almost 1,000 more than the Martini Mustang.
A six-speed Magnum transmission dispatches that power to the ground, while Pirelli PZero tires are tasked with (somehow) trying to grip the road. Baer brakes hide behind those HRE rims, while JRI coilovers and HyperTech springs bless the Camaro with some degree of competency in the bends.
