Porsche 911 GT2 RS top speed run on Autobahn

If you’ve ever wanted to know how long a 991 Porsche 911 GT2 RS takes to hit its top speed, wonder no more.

In 57 seconds, the Widowmaker hits 342km/h, or an indicated 356km/h.

At 1:01 in the video above, produced by German outlet sport auto, the vicious 911 launches from a standstill, and hits 100km/h in what looks like less than three seconds.

It then rockets on to 200km/h in around 8 or 9 seconds, the mix of speedo timing and filming angle makes it a challenge to be properly accurate here. 300km/h isn’t far out of reach by this point, taking only another dozen seconds or so to reach from 200.

At this point, the Autobahn would be flying past outside, with any traffic on the road likely just seeing a winged silver blur.

But the driver’s not done, pushing the GT2 RS for another 35 seconds until the dial reads ‘356km/h.’

Considering Porsche claims the GT2’s top speed is 340km/h, that’s not a bad effort. But a shot of a GPS beside the car’s own readout clears things up. “Max tempo” (or ‘max speed’ to us) on the GPS reads 342km/h, just two kays over the ‘top speed’.

As a side note, the average speed for the full trip this GT2 RS has taken, including the lead up to the top speed run – and likely some driving afterwards – averages out to 136km/h. That’s for 1 hour and 38 minutes of driving, over 222km.

If your trip computer ever tells you that in Australia, you’ve probably just lost your licence.
