Ex-Formula One racer Mark Webber and tennis ace Maria Sharapova recently jumped into the driver’s seat of a yellow Porsche 911 GT2 RS to experience the car and scare each other to death.

Unveiled in the middle of last year, the GT2 RS the most powerful road car to ever wear the famous 911 badge and holds the Nurburgring Nordschleife production lap record with a blistering 6:47 lap. For almost anyone that holds a driver’s license, the RS offers simply out-of-this-world performance.

However, for a racing expert like Mark Webber, driving one is simply another day in the office.

The Australian played a part in the development of the car and is very familiar with the way it handles and the performance it provides. By comparison, Maria Sharapova isn’t as experienced behind the wheel but has driven some serious metal in the past thanks to her role as a Porsche ambassador.

Powering the 911 is a 3.8-liter twin-turbo flat-six engine delivering 690 hp and 553 lb-ft of torque. This engine is mated exclusively to a seven-speed PDK dual-clutch transmission that allows the car to hit 62 mph (100 km/h) in a blistering 2.8 seconds. With enough room, the car will keep on accelerating until 212 mph (340 km/h).

Other key components of the car include its rear-wheel steering, variable locking rear differential, various lightweight components, and custom aero parts.
