911 GT2 RS shows it prowess on the track compared to base Carrera. GT2 RS particularly strong on the long sprint to 150 mph (241 km/h).

Is the Porsche 911 GT2 RS really worth the price increase from the 911 Carrera?

Autocar sets out to test the two models side-by-side in this video.

First off, the GT2 RS is a full second faster than the Carrera in the 0 to 60 mph (96 km/h) sprint 3.7 seconds vs. 4.7 seconds. But the numbers get more impressive for the GT2 RS (and more disparate) after that. To reach 150 mph (241 km/h) the GT2 RS takes just 15 seconds flat compared to the 28.7 seconds of the Carrera.

Roughly twice as quick for about double the price - a balance, some may say.

And the adjustable dampers, standard on the GT2 RS, come in handy with the GT2 RS out-handling the Carrera and staying easily ahead of it on the track.

But the GT2 RS's price of €199,500 compared to even the €104,935 for the Carrera GTS becomes a moot point for consumers now - the 500 units that Porsche will build of the GT2 RS are already sold out.
