2018 Jaguar E-Pace Rollover Stunt:

In 2017 Brian G. McHenry was hired by Jaguar UK to design the 2018 Jaguar E-Pace Rollover Stunt. McHenry used computer simulation to modify the original spiral jump stunt for the 2018 Jaguar E-Pace vehicle. The stunt was where the 2018 Jaguar E-Pace was driven by a stunt driver up a ramp and rolled 360 degrees and landed on its wheels and continued driving down the road.
