Manufacturers often boast
of motorsport influence in
their powerplants but the
GT3’s motor is very much

alongside the company’s

stick with natural aspiration.
No, it can’t match the
whizz-bang performance of
turbocharged rivals – including
its own 911 Turbo sister – but,
although the engine doesn’t get
out of bed for much less than four
grand, its enthusiasm for revs –
and the savagely joyful noise it
makes at full chat – encourage the
sort of hard use the car seems to
revel in. Throttle response is also
sharper and keener than anything
with forced induction.
The standard PDK delivers
ultra-quick changes all of the
time, and adds a head-jolting
torque bump to upshifts in its
punchier Sport mode.
As usual, Porsche laid on a
track for its press debut. The tight
and technical 3km-long Circuito
Guadix in Granada, Spain, proved
that the dual-clutch ’box is ideally
suited to hard circuit use. While
the manual is noticeably slower,
and its six ratios are spread more
widely, it has the same near-
perfect shift action as the 911R,
and the engine’s screaming top
end masks the gaps.
Track use also demonstrated
the GT3’s near total resistance
to understeer, certainly once the
super-sticky Pilot Sport Cup 2

in the GT3 Cup racer. Power has
increased by 18kW to 368kW,
torque has risen by 20Nm to
460Nm and is available across a
broader spread of the rev range.
More importantly, the redline
is still set at a dizzying 9000rpm,
750rpm beyond where peak power
arrives, making the GT3 – by our
reckoning – the highest-revving
sportscar currently on sale.
Design has been given a
nip-and-tuck, with redesigned
bumpers and a slightly higher-
mounted rear wing which, in
conjunction with a new diffuser,
has increased peak downforce
by around 20 percent while also
cutting drag. Oh, and there are
now some very cool ram-air ducts
to direct more flow through the
engine cover.
Other differences, although
plentiful, soon fade to invisibility;
apart from the welcome arrival of
an improved touchscreen interface


  • and the same steering wheel that
    was fitted to the 918 Spyder – the
    cabin feels unchanged.
    But while the driving
    experience is familiar, it’s
    noticeably sharper. The engine
    remains a masterpiece and five
    minutes in its company is enough
    to vindicate Porsche’s decision to


tyres were warmed through. It’s
a car with the security to tolerate
serious abuse, not something
that could be said of pre-GT3
lightweight 911s, but also with
more than enough finesse to
reward accuracy and precision.
On road, it is even more
impressive; the dampers
deliver an unexpected level of
compliance and the steering
remains chatty even without
track loadings. On dusty Spanish
roads the track-focused tyres
were often short of grip, but the
GT3’s helm flags the front end’s
battle between grip and slip better
than a semaphore school.
It’s noisier than a regular
911 when cruising, economy takes
a bit of a hit over the standard
car’s fuel-sipping turbo engines
and it does without rear seats,
but it’s definitely more everyday
viable than anything else this
track-focused.
While this 911 will doubtless
spawn an even faster – and even
more expensive – RS sister, the
regular car could well be the
better piece of engineering.
If we had to choose just one
performance car to keep forever,
it would be this one.
