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 recalls select Tahoes, Yukons, Escalades for rear driveshaft issue

GM is recalling a number of its full-size SUVs due to an issue with the rear driveshaft assembly that could ultimately result in driveshaft failure. The actual number of total vehicles involved in the recall is small at just 1,789, but it’s spread out across the entire 2021 model year full-size GM vehicle lineup. That means a small number of every model is being recalled, including the Chevrolet Tahoe, Suburban, GMC Yukon, Yukon XL and the Cadillac Escalade and Escalade ESV. GM traced the issue back to certain driveshaft assemblies with ball bearings that were not properly heat treated. If theyÂ’re not properly heat treated, GM says that the balls may deform over time, causing noise and vibration. Continue to drive in this condition, and GM says the affected joint in the driveshaft assembly could seize, causing loss of drive power. However, the problem wonÂ’t present itself all at once, as GM says there will be a gradual increase of noises and vibrations before total failure. For those few owners with affected vehicles, GM says that it will replace the left and right rear driveshaft assemblies with properly-built units. Per usual with recalls, this will be done at your local dealership at no cost to the owner. If you have one of the recalled SUVs, expect to be notified mid-March. Related video:

2016 Chevrolet Camaro First Drive [w/video]

The Autoblog gang was downright stoked to learn the 2016 Chevy Camaro was next on our test-car docket. Then we found out it was the V6 model. Buzzkill. We were hoping for the snorting V8, or at least the spunky new turbo four-cylinder. The V6? Meh. We've been driving V6 Camaros for, like, six years. It's what you buy if you can't afford anything better, or so say horsepower snobs as they wrinkle their noses and cut their coffee with 93 octane. But after a week with the six-pot Camaro, we'll admit it: we were wrong. The all-new 3.6-liter V6 is strong, sounds good, and is damn fun to drive. Its 335 horsepower and 284 pound-feet of torque appear modest by modern standards, but they power the Camaro to 60 miles per hour in 5.1 seconds with the automatic, or in the case of our manual-equipped test car, 5.2 seconds. That's almost half a second quicker than the new turbo four-cylinder model. Yes, it has the same displacement as the old V6. No, it's not the same engine. Upon closer inspection, the V6's potency shouldn't come as a surprise. This engine is from General Motors' newest family of dual-overhead cam powerplants that launched in the Cadillac CTS and ATS. Yes, it has the same displacement as the old V6. No, it's not the same engine. Don't be fooled, and don't underestimate it at stoplights. The strapping V6 is unsuspectingly good, but it's just one of many improvements for the sixth-generation Camaro. Chevy's coupe is lighter, faster, and more modern looking inside and out. It starts with a rear-wheel-drive chassis donated from the Cadillac ATS, though about 70 percent of the components are unique to the Camaro. The 2016 model is about two inches shorter in length (thanks to a shorter wheelbase) and about an inch has been removed from height and width compared to the 2015 model. These lighter underpinnings jumpstarted the Camaro's weight-loss plan, and thanks to extensive use of aluminum, the V6 with the new eight-speed automatic transmission weighs 3,435 pounds – 294 less than its predecessor (the manual-transmission V6 Camaro weighs 3,448 pounds). The V8, meanwhile, sheds 223 pounds. One by one, these elements would merely enhance how the Camaro drives, but taken collectively, they invigorate the new model. It feels much more confident and agile in all circumstances. Put simply, it's a sportier car.
