700HP CADDY DIALS 'SOS' AFTER 11SEC 1/4 MILE

Pulling 0.99g on a drag strip after putting in a quarter-mile run in just 11 seconds triggered this Caddy's onboard 'OnStar' safety system to call for help!

As you'd expect, this is no ordinary Caddy - the CTS-V in question has a 700bhp tuning package from Hennessy Performance, and is described by Hennessy as a 'four-door ZR1'.

But still being a CTS at heart, it retains the 'OnStar' assistance package fitted to higher-end GM cars. Amongst its other features, OnStar is designed to automatically call for assistance when it detects a crash has taken place.

As this video shows, the forces caused by the modified Caddy's extreme acceleration triggered such a call, with amusing results. You can watch the run in the video below, and bear in mind as you watch that this isn't even the fastest CTS that Hennessy makes.
