Engine.
Located just above the tarmac and posi
tioned low down in the rear is the newly
developed water cooled six cylinder alu
minium engine with four valves per cylin
der, VarioCam and a separate engine
oil tank.
This high revving concept promises excep
tional
power. The engine has a maximum
speed of 9,000 rpm.
Maximum torque
of 440
Nm is available at 6,250 rpm and
maximum power output is
produced
at 8,250 rpm. Particularly light weight
Two hundredths of a second are worlds apart.
What are we waiting for?
titanium connecting rods facilitate the
unit’s impressive rpm capability.
The engine taps into its capacit y of
3.8 litres to generate a maximum power
output of 350 kW (475 hp). This corre
sponds to a power output per litre of
92 kW (125 hp). The new 911 GT3 tears
acceleration limits asunder: it sprints
from 0 to 100 km/ h in just 3.5 seconds –
0.6 seconds faster than its predecessor.
The 200 km/ h mark is also reached
0.9 seconds sooner, after precisely
11. 4 s e c o n d s .
How is that possible? Thanks to a weight
to power ratio of only 4.1 kg / kW
(3.0 kg / hp), a great deal of fine tuning
and the short transmission ratios of
Porsche Doppelkupplung (PDK). These
increase torque and acceleration potential
in all seven gears. Limits? The new
911 GT3 accepts that only the other side
of the 315 km/ h mark is beyond its reach.
Direct fuel injection (DFI), fitted in a
911 GT3 model for the first time, makes
a decisive contribution to the efficiency
of the engine – and its power output. It does it with millisecond precision and
a pressure of up to 200 bar for optimum
mixture formation and combustion in the
combustion chamber.
