Engine Speed (rpm)
911 GT2: 680 Nm from 2,200 to 4,500 rpm, 390 kW (530 hp) at 6,500 rpm
The benchmark sprint to 100 km/h
(62 mph) is completed in
3.7 seconds; 200 km/h (124 mph)
requires just 11.2 seconds.
Maximum speed – if you really
want to put it to the test – is
329 km/h (204 mph). Even more
impressive is the power-to-weight
ratio of 361 hp per tonne and
the specific power output of
147 hp per litre. Fuel economy
is also exceptional for a car
with such high performance.
There is nothing ordinary about
the 911 GT2 and it exceeds even
the highest expectations. In
other words: everything you'd
expect from the most powerful
road-going 911.
