GM throttles back Chevy Malibu, Buick LaCrosse production over swollen inventories

As inventory of the Chevrolet Malibu and Buick LaCrosse continues to pile up, General Motors will be idling its Fairfax Assembly Plant for two weeks, according to Automotive News. This move comes about a month after the plant was shut down for three weeks in late December and early January for the same reason. As of January 31, the GM had a 94-day supply of Malibu stock while the LaCrosse was a little worse with a 117-day supply.
Just last week, GM announced that it would be investing $600 million in upgrading this plant, but it's unclear what future plans the company has in store for Fairfax considering slow sales of both the plant's models. We do expect a refreshed and more luxurious LaCrosse shortly and an early design update for the Malibu to be announced at some point this year, although we have had no official word as to when either will happen.

Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.

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.
