Video: Mark Webber Porsche 991.2 911 GT3 RS onboard

Mark Webber is so relaxed fanging the fastest naturally aspirated Porsche of all time, on a racetrack, that he leaves the PDK shifter in automatic mode.

As you ride onboard Porsche's new 991.2 911 GT3 RS for a lap of the Nurburgring GP circuit, if you watch carefully he's not using the paddles and it's a surprise at all he doesn't yawn as he races down the straights at up to 240km/h.

Of course, in his duties as a Porsche ambassador, Webber is plenty familiar with cars like the new GT3 RS and it's one vehicle you can leave in full auto mode no matter how hard you're driving, such is the intuitiveness of its gearchanges in max-attack mode.

Webber belts the 383kW/470Nm naturally aspirated GT3 RS around the 5.148km circuit like it's a cakewalk. That's no surprise given his F1 experience, and the fact that the Nurburgring was the scene of his first F1 win in 2009.

Interestingly, the Aussie F1 legend takes a very different line around the circuit than the Porsche instructors who were chaperoning journalists at the GT3 RS's international press launch. For all his precision and calmness behind the wheel, there's no denying this is the quickest way around the track in the new race-bred Porsche.

Webber, who won nine grands prix and finished on the F1 podium 42 times, is driving a Weissach Package-equipped GT3 RS which features exotic weight-saving materials such as titanium exhaust tips, magnesium wheels, carbon-fibre swaybars and droplinks and special carbon-fibre reinforced plastic.
