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 521,817 cars in two campaigns

General Motors is issuing two, separate recalls covering a total of 521,817 vehicles worldwide. The larger campaign covers 468,887 units of the 2011-2012 Chevrolet Malibu. Specifically, 437,045 of these are in the US, and the rest are outside the country. In these sedans, a steel cable that connects the seat belt to the vehicle can fatigue and separate. GM knows of 36 claims about the problem but only one minor injury. According to The Detroit News, this happened when a taxi driver hit his head. To fix things, dealers will replace the "outboard lap mounting bracket," which will move the tensioner rearward. They'll also inspect and if necessary replace the steel cable and lap pretensioner. In the second campaign, 52,930 examples the 2015 Chevy Colorado and 2015 GMC Canyon have seat frame attachment hooks that were installed incorrectly during assembly. GM hasn't received any reports of crashes, injuries, or fatalities about this problem. Dealers will inspect the affected trucks and repair as necessary. GM spokesperson Alan Adler told Autoblog that he didn't yet have a specific date when affected owners would receive official mailings about either of these recalls. GM Statement General Motors is recalling 48,309 2015 model year Chevrolet Colorado and GMC Canyon midsize pickup trucks in the U.S. because certain seat frame attachment hooks were not properly attached to the vehicle body during assembly. Dealers will inspect the potentially affected seats for proper installation and repair if necessary. GM knows of no crashes, injuries or fatalities related to this condition. The total vehicle population of the recall is 52,930 including 4,620 vehicles sold in Canada. General Motors is recalling 437,045, 2011-2012 model year Chevrolet Malibus in the U.S. because the flexible steel cable that connects the safety belt to the vehicle can fatigue and separate over time as a result of occupant movement in the seat. Dealers will replace the outboard lap mounting bracket to relocate the tensioner slightly rearward. Dealers will inspect the cable and, if necessary, replace the lap pretensioner. GM knows of 36 claims, no crashes or fatalities and one minor injury reportedly related to the condition. The total vehicle population of the recall is 468,887 including Canada, Mexico and exports.

GM execs fired over fraudulent India emissions testing

General Motors hadn't had a recall in India since 1995. That changed when it was discovered that certain employees were playing tricks with local emissions testing in order to ensure passing grades for engines. More than ten GM Powertrain employees in India and the US have been let go over the ensuing emissions flap, including Sam Winegarden, VP of global engine engineering, a man who has been with the company since 1969, leading development of some marquee powerplants.
According to Automotive News, an internal investigation revealed that employees "violated testing procedures," sometimes swapping specially prepared low-emissions engines during testing regimes for the Chevrolet Tavera SUV equipped with the 2.0-liter and 2.5-liter engines. Employees were also manipulating weights in order to get vehicles placed into different emissions categories. The discovery has led to GM recall the 114,000 Taveras produced over an eight-year period and halting their production and sale.
The Economic Times of India reports that the issue is due to "a faulty component." GM has developed a solution to the issue, and once it is validated in testing and approved by the Indian authorities, the recalled vehicles will be fixed at dealers and production will resume.
