When it comes to the Porsche 911, you can't make a bad decision. All of them are powerful and, more importantly, handle beautifully, but seeing how they compare in a drag race is always interesting. The scenario in the video below sees the latest 911 Turbo S go up against the previous generation's insane GT2 RS. Although from the same family, these cars are very different.

The Turbo S produces 640 horsepower and 590 lb-ft of torque while the GT2 RS makes 700 hp and 553 lb-ft. Both have an eight-speed dual-clutch auto changing gears, but the Turbo S has the added benefit of all-wheel-drive, and with conditions looking damp, the lesser-powered Porsche should be in with a shot here.

Out of the gate, the rear-wheel-drive GT2 RS is still astonishing. When Porsche claimed a 0-60 mph sprint time of 2.7 seconds in a car with 700 hp, it seemed insane that such a thing could be achieved by powering just one axle, but even in the wet, the more powerful car quickly asserts its dominance. As always, however, power is nothing without control. With a different driver behind the wheel, the AWD Turbo S is able to pull ahead and stay there, and it takes another attempt for the GT2 RS to reclaim its position on top, which just goes to show that anything can happen in a race.

Despite the overall loss, the 911 Turbo S is an incredibly satisfying machine that can decimate lap records. It's pretty impressive if you find an unrestricted piece of tarmac to fully exploit its engine on too, so we doubt that this video will cause any sleepless nights for those who already own one. Still, there's no getting away from the fact that the GT2 RS is on another level. While we have seen it on a winding circuit on numerous occasions, this video just makes us respect the road-legal racer even more. Even in the rain and even away from its comfort zone, the GT2 RS is an animal. We can't wait for the next one.
