OnStar 'ignition block' disables stolen vehicles

OnStar, General Motors' in-vehicle safety and communications system, has launched a service to keep car thieves from starting a vehicle that has been reported stolen. As of July 20, three stolen cars had been disabled by the technology, called "remote ignition block." The feature is available on select 2009 and 2010 GM models. Subscribers must report their vehicles stolen to police officials and request assistance from OnStar, which then sends a signal that prevents the car from restarting.

You wait ages for a new Corvette, and then six weeks after the new Stingray bows in at the 2013 Detroit atuo show, its soft-top sister is revealed at the Geneva motor show. The latest C7-generation Corvette drop-top uses the same mechanical package (big V8 up front, power sent to the rear wheels) as its fixed-head sister but adds an electrically-folding soft-top roof that you can lower remotely via pushing a button on the key fob. You can also drop the roof while on the move, at speed of up to 31mph.
