Ever since its debut in 1974, the Porsche 911 Turbo has symbolized extreme performance (beaten only by the completely bonkers GT2). While the original 930 was an absolute handful to drive because of its massive turbo lag and propensity for oversteer, force-fed 911 Turbos have grown quite compliant over the years while producing increasingly mind-blowing performance numbers.
At first glance, the 991 2014 911 Turbo doesn't appear to be that big of
an improvement over the 997. Output from the 3.8-liter twin-turbo
flat-six goes up by 20 hp and 7 lb-ft to 520 and 487, respectively. The
Turbo S gets a 30-hp bump to 560 from the 997's 530, but torque is
unchanged at 516 lb-ft. Curb weight of both remains at slightly over
3500 pounds, with the Turbo S closer to 3550 pounds. One big powertrain
change is the departure of the manual transmission, with all 2014 911
Turbos offered exclusively with Porsche's seven-speed PDK twin-clutch
automatic. Purists may balk, but even the most skilled drivers will be
hard-pressed to hit the claimed 0-60 marks of 3.2 seconds (Turbo) and
2.7 seconds (Turbo S) without the PDK's lightning-quick shifts.
Speaking of those performance numbers, the last
997 911 Turbo we tested needed 3 seconds flat, and the last Turbo S went
into Veyron territory by hitting 60 in just 2.7 seconds, beating
Porsche's estimates. We wouldn't be surprised if we saw 2.5 seconds out
of the 2014 Turbo S -- aside from being astounded by just how quick that
is. Quarter-mile times should be similarly jaw-dropping -- we saw 10.9
seconds from the 2012 Turbo S and 11.2 seconds for the 2010 Turbo, which
was equipped with a manual rather than a PDK. Claimed top speeds are
196 mph for the Turbo and 198 mph for the Turbo S.
Handling performance should increase as well,
with the 2014s fitted with active aerodynamics (a three-stage front
spoiler and deployable rear wing with three positions), rear-wheel
steering, and the new Porsche Traction Management all-wheel-drive
system, which can send more power to the front wheels than before. The
991s also get
