The new 911 GT3 RS and the 911 GT3 |
You can't get much closer to the truth.

The engines.

Powering the 911 GT3 models is a
liquid-cooled six-cylinder Boxer
engine with four-valve technology
and enhanced VarioCam variable
valve timing (page 36). The vehi-
cle's high-performance concept
produces an impressive maximum
engine speed of 8,500 rpm.
In the 911 GT3, the engine gener-
ates 435 hp from a total displace-
Drive
ment of 3,797 cubic inches,
corresponding to an output of
114 hp per liter. The maximum
torque is 317 lb.-ft. at 6,250 rpm.
The 911 GT3 accelerates to
60 mph in 4.0 seconds with a
top track speed of 194 mph.
The 3.8 liter engine in the new
911 GT3 RS delivers even more
power: 450 hp. The output is
118 hp per liter. This increase is
due to the two new double-flow air
filter housings and the new vari-
able intake manifold with larger
intake tubes than those used on
the 911 GT3. The greater through-
put of air increases engine power.
In terms of performance data,
the maximum torque of 317 lb.-ft.
is reached at 6,750 rpm.
