Powering the new 911 GT3 is a
water-cooled six-cylinder Boxer
engine with four-valve technology
and enhanced VarioCam variable
valve timing (page 24). It gener-
ates 320 kW (435 hp) from a
total displacement of 3,797 cm 3 .
The maximum torque is 430 Nm.
The maximum engine speed is
8,500 rpm.
The new 911 GT3 reaches
100 km/h (62 mph) in just
4.1 seconds, with a top speed
of 312 km/h (194 mph).
The weight-to-power ratio is
3.2 kg per hp and the new
engine provides an output of
115 hp per litre.
In short: the popularity of the new
911 GT3 is assured due to this
increase in power, yet similar fuel
consumption.
This efficiency is demonstrated
by the vehicle’s compliance with
the stringent requirements of
the Euro 5 emissions standard.
The new 911 GT3 | Drive
A consistent supply of oil to the
engine, even at times of high
lateral acceleration, is ensured by
a dry sump lubrication system
(page 24) with an external engine
oil reservoir. The oil is cooled by
an oil-water heat exchanger. Both
of these systems have proven
themselves on the racetrack.
An extremely lightweight titanium
connecting rod and lighter pistons
reduce oscillating masses, thus
ensuring dynamic engine speed
development. The inlet and
exhaust valves are actuated by
extremely lightweight tappets
and hydraulic valve clearance
adjustment. This enables a maxi-
mum engine speed of 8,500 rpm
which, together with the short
sporty gear ratios, provides
plenty of performance potential.
Added to this is a variable intake
manifold with two resonance
valves (page 26) which work
together with the sports exhaust
system to ensure efficient cylinder
charging and high throughput
rates. The large volume of the
exhaust system supplements the
low-resistance intake manifold
to improve cylinder charging and
increase performance.
The development of the new
engine. A challenge as always.
Which is why it is proof of our
core values.
3.8-litre Boxer engine
Perhaps the clearest evidence of our core values.
