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 Corvette Stingray "colorizer" lets you chase the rainbow

After you've convinced your better half to let you buy a new Corvette, then comes the hard part... actually figuring out which 'Vette you want. While Chevrolet has yet to release the official configurator for the 2014 Corvette Stingray, it did give us something else to kill some time playing around with.
The C7 Corvette "colorizer" recently went online, and it lets you look at the car in all of its available colors and wheel options from four different angles so that when this car does go on sale, you know exactly which one you want. It includes the Corvette's full pallet of colors including Torch Red, Laguna Blue and the hue you see above, Velocity Yellow. Toss in the black wheels, and we're sold. If you have some time this afternoon, be sure to check it out the Corvette colorizer for yourself, and even if you don't have the time, we've put together a gallery with all of the possible color combinations.

Detroit Three's lucrative pickup war intensifies as Ram makes big gains

DETROIT — The battle for profits from sales of large pickup trucks is intensifying among the Detroit Three automakers as sales of small cars in the United States shrivel. For decades Ford has had the single best-selling truck brand in its F-Series trucks. General Motors' Chevrolet brand was a solid No. 2, and Fiat Chrysler Automobiles' Ram was a distant third. Now, that hierarchy may be in flux. Sales figures for December and the fourth quarter released on Thursday show Ram tied with GM's Chevy for the No. 2 spot, as sales of the redesigned Ram pickup surged, fueled in part by demand for an optional 12-inch (30.48 cm) dashboard screen. Chevy not long ago held second place to Ford by a wide margin. GM executives said on Thursday they are bullish on their new GMC and Chevy trucks for 2019.Related: How the Detroit Three's pickups compare on paper 2019 Ram 1500 Laramie review 2019 Chevy Silverado 2.7L four-cylinder review 2019 Ford F-150 2.7L EcoBoost review "There's no doubt this segment (pickup trucks) is one of the epicenters of the auto wars," said Sandor Piszar, director of marketing for Chevrolet at GM. "It's been that way forever, and we wouldn't have it any other way." On Wall Street, investors give electric car leader Tesla a higher valuation than any of the Detroit automakers. But in the nation's heartland, big pickups remain far more popular and profitable than any electric car — and most other consumer vehicles of any kind. Large pickups generate at least $17,000 a vehicle in pretax profit for GM, the company has indicated in disclosures to investors. By contrast, many Detroit Three sedans are so unprofitable, their manufacturers have decided not to build them anymore. 'Hotly contested' Sustaining sales and pricing in the large-pickup segment will be critical in a year when most forecasters expect overall U.S. car and light truck sales to fall. Ford's U.S. sales chief, Mark LaNeve, on Thursday called the F Series "the backbone of our franchise" during a conference call, and added the "segment will continue to be strong, but hotly contested" in 2019. Automakers are banking on pickup truck sales to stay strong even if U.S. interest rates continue to rise. Rising interest rates translate into higher monthly car payments and are expected to deter some buyers in 2019. GM has said 27 percent of Chevrolet and GMC trucks — which can haul trailers by day and substitute for a luxury sedan by night — sell for more than $55,000.
