Cockpit video shows driver Sean Kennedy taking the Hennessey Ford GT to the Texas limit.

This is a cockpit video of a Hennessey Ford GT taken up to 235 mph (378 km/h) at the Texas Mile Run on Monday May 30, 2011.

The driver is Sean Kennedy but the car belongs to Mark Heidaker. It is a 2006 Ford GT tuned by Hennessey and fitted with a custom twin-turbo system which can be configured to deliver up to 1,000 horsepower (745 kW / 1012 PS) on the GT.

If you ever happen to be sitting in the driver seat of one of these, just make sure you only drive the thing in a straight line. You may not want to take the full 1,000 horses into a heavy curve.
