Video: Onstar gives Hennessey a ring after pulling .99 G launching a 700 HP CTS-V

Just last week we reported about how the satellite service Onstar stopped its first car jacking by disabling a 2009 Chevrolet Tahoe only 16 minutes after it was taken thanks to their Stolen Vehicle Slowdown system. Well this time the little blue button was still on alert, except that there was no cause for concern. The American tuning house Hennessey was testing their 700 HP Cadillac CTS-V at the drag strip when a hard launch measuring as much as .99 G of longitudinal force triggered one of Onstar’s safety parameters and caused an operator to contact the driver mid run down the 1320. Luckily no one was actually in need of assistance at the time, but this is just more reassuring proof that Onstar has you covered.
