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 recalling over 40,000 Chevy, Pontiac and Saturn models over fuel pump woes

The National Highway Traffic Safety Administration has issued a recall for a number of General Motors cars and crossovers bought or currently registered in the hot-climate states of Arkansas, Arizona, California, Nevada, Oklahoma and Texas. As many as 40,859 units consisting of the 2007 Chevrolet Equinox, Pontiac Torrent and Saturn Ion and the 2007-2009 Chevrolet Cobalt (shown) and its Pontiac G5 twin are being recalled for potential fuel leaks.
This recall is being issued due to potentially faulty fuel pump components that can crack and cause gasoline to leak from the return or supply ports and possibly cause a fire. NHTSA has not indicated how many fuel leaks or vehicle fires have been reported. As a fix, GM will replace the fuel pump modules on all affected vehicles free of charge. Since Pontiac and Saturn have been shuttered, owners will be able to go to another GM-brand dealership to have their vehicles repaired.
While the list of affected cars and crossovers varies by state and model year, if you own any of these models and live in Arizona, California, Florida, Nevada, Oklahoma or Texas, be sure to check the official notice below for more details.

Helicopter crashes on Top Gear Korea set while chasing Corvette ZR1

The formula of Top Gear Korea is seemingly about the same as it is everywhere else in the world, including the flagship British original: involve interesting cars in fantastical situations with charismatic hosts. That prescription has proved to be pretty reliable over the years, and has lead to some truly memorable and exciting pieces of television.
Something like that was undoubtedly what the Korean producers were after when they lined up this segment - a drag race between a Chevrolet Corvette ZR1 and an AH1 Cobra military helicopter. The planners almost certainly did not expect the filming of the segment to go quite as wrong as it actually did, with the helicopter actually crashing into the dirt after the "drag race" had been completed. Thankfully, we're told that no one was seriously injured in the crash, but the footage, in the video below, is pretty damn chilling to watch, nevertheless.
