The new Porsche 911 Turbo S is an impressive car when it comes to performance. At 641 horsepower coming from a twin-turbo flat-six engine, the 911 Turbo S is just as fast as much more powerful supercars, largely thanks to its AWD system and tremendous launch control. But how does it compare to other cars that have similar output and power-to-weight ratio? Well, the McLaren 600LT, for instance, is no match for the German coupe in short sprints.

It also packs a lot less torque at 457 pound-feet, a significant 133 pound-feet behind the Turbo S.

On the other hand, the McLaren is 520 pounds lighter than the Porsche. At the same time, it wins the power-to-weight ratio with 428 horses per tonne versus the 911's 397 horsepower per tonne. The McLaren should be quicker in theory, but the Porsche's all-wheel-drive and launch control systems cancel McLaren's superior power-to-weight ratio.

In this comparison by Carfection, the 600LT has no chance against the 911 Turbo S when racing off the line. While the 600LT struggles to find traction in the first couple of seconds under full throttle, the 911 takes off without breaking a sweat. A couple more seconds in the race and the 911 Turbo S becomes unbeatable to the quarter mile. The 600LT has the ability to catch up in a 0 to 124 mph sprint, as both cars are rated at 8.4 seconds, but the Porsche will win every short sprint battle against this McLaren.
