It
looks familiar. It sounds familiar. It is definitely a 911. But unlike
the 997, which was a cleverly cost-conscious metamorphosis of the 996,
the 2012 Porsche 911, code name 991, is an all-new car. Its body, which
now uses aluminum for the doors, fenders, and engine- and
luggage-compartment covers, features a much more modern, cab-forward
design. The new interior is inspired by six generations of 911s but also
takes cues from the Cayenne and the Panamera. In addition, the
engineers have prepared a new evolution of boxer engines, the world's
first seven-speed manual transmission, and a chassis with a bigger
footprint that creates a more confident stance for Porsche's icon.
"The
991 takes a step ahead in all key areas," states chief engineer August
Achleitner, a twenty-eight-year Porsche veteran who has been involved
with every 911 since the 1990-94 964-series.
"The
new model is even better balanced, even more compliant, even more
untouchable," claims Walter Roehrl, multiple rally champion now involved
with Porsche development. Both men will be demonstrating the new 911,
while we ride along to get our first taste of the latest Porsche.
Still
fit as a fiddle at age sixty-four, Roehrl is an eerily fast yet
incredibly smooth driver. Despite the light drizzle, the lanky Bavarian
establishes what felt like a new speed record on the sleepy Nockalm
pass, which is dotted with 90-degree hairpins, blind crests, and
pupil-widening sweepers. It was on this very road that Ferry Porsche and
senior designer Karl Rabe put their type 356 roadster through its paces
back in the late 1940s.
Seemingly
immune to g-force, oncoming traffic and wayward cattle, Walter keeps
talking while tap-dancing on the pedals and twirling the wheel. "There!
Follow the nose of the car. See? It turns in like a swoosh. And it
sticks, sticks, sticks. No more understeer. Incredible. All that tugging
and pulling is gone. This 911 no longer fights its driver. Instead, it
follows the line like a ruler, stays flat as a Dover sole, and is so
well balanced you would never believe the engine sits aft of the rear
axle."
Driver
change. Roehrl steps out, Achleitner hops in. The steering wheel whirs
into position at the push of a button. He adjusts the new eighteen-way
adaptive sport seat, which has adjustable side bolsters, heating and
ventilation, extendable cushions, and multidirectional lumbar supports.
My hope that Achleitner will select a more leisurely pace is squashed
the instant he takes off, revving to 7500 rpm in first and second gears
and using every inch of suspiciously slippery blacktop through the fast
sweepers that lead to the summit. "The wider front track makes all the
difference," claims the chief engineer. "It rivets the front end to the
tarmac, eliminates any trace of nervousness, and enhances stability and
confidence. The longer wheelbase helps, too. The 991 simply feels more
grown-up, more competent, more sure-footed. Those who regularly push the
car to the limit may appreciate special equipment packages that further
enhance braking, cornering and roadholding."
Extras
on our lime-gold metallic Carrera S include carbon-ceramic brakes,
Porsche Torque Vectoring Plus with dynamic torque distribution via a
side-to-side differential lock, active dampers with a lower sport
suspension, twenty-inch wheels, magnetorheological engine mounts, and
PDCC active roll compensation. This system employs hydraulic extension
elements that split the antiroll bars to reduce unwanted body movements,
flatten the ride, and enhance roll stiffness. Which of these options
are must-haves? Roehrl and Achleitner look at each other, mutually
search for words, and eventually agree that even the no-frills base 911
should satisfy most needs.
A
lot of controversy accompanied the gestation of the new electric power
steering that debuts here. It is lighter and more efficient than the
previous hydraulic system, but does it provide the same quality of
feedback and response? "Early on in the development process, we had
problems on low-friction surfaces," recalls Roehrl, who drove the car
near the Arctic Circle and on the Nuerburgring. "The phenomenon was
called snap-over, and it only showed at the limit when ultrafast
corrections were required. But engineering quickly fixed it, and the fix
was later backed up by various software updates. Although the new
steering may face an acceptance problem among some Porsche purists, in
my view it is superior to a conventional rack. In critical situations it
can support the driver, for example, by enhancing the self-centering
motion or the directional stability on split-friction surfaces." Extra
money buys Power Steering Plus, which can adjust power assistance at
speeds below 30 mph and in particular during parking maneuvers.
Our
roller-coaster drive through the most picturesque parts of Styria,
Carinthia, Salzburg, and Tyrol put the new 911 through a continually
changing set of paces. On the narrow and winding toll road that leads to
the top of the Malta valley, the Porsche impressed with newfound
maneuverability. Up and down the challenging Katschberg, we relished the
extra torque in combination with the higher rev limit, as well as the
more powerful brakes that benefit from bigger cooling ducts, lighter
discs, and six-piston front calipers.
On
paper, the 400-hp new 911 Carrera S is only a blink of an eye faster
than last year's 385-hp 997. At 4.3 seconds, the PDK-equipped version
accelerates to 62 mph 0.2 second quicker than the model it replaces. In
terms of top speed -- 188 mph versus 186 mph -- it's basically a dead
heat. In real life, however, there is much more between these two
siblings than the numbers suggest. In direct comparison to our
best-of-the-old 911 GTS chase car, for instance, the new 991 was lighter
on its feet, more agile, more stable, and more homogenous overall. But
what exactly are the elements that make the difference? Chief engineer
Achleitner: "Depending on specification, we took out between 30 and 45
kilos [66 to 99 pounds] in weight, and it shows. In addition, we
extended the wheelbase, widened the track, lowered the suspension in two
steps by up to 20 millimeters [0.8 inch], and modified the proportions.
These measures permit higher cornering speeds, help to speed up
turn-in, and allow only a relatively small measure of understeer and
oversteer." It seems as if the days of tricky-handling 911s are over.
Since
Austria has embraced the mobile radar trap, Roehrl was careful before
he put his foot down and let the car fly. In the 911, part throttle is
by no means a joyless anticlimax. Thanks to a variety of new fuel-saving
techniques (including automatic stop/start), it is actually fun to
squeeze extra miles out of the 16.9-gallon tank. Perhaps the most
intriguing is the free-wheeling mechanism, which decouples engine and
transmission. To summon it, you can either lift off -- but not quickly
-- or select the highest available ratio via the upshift paddle. In
response, the engine speed drops to idle and the gear indicator displays
the ratio in which the journey is going to continue.
At
the end of day one, the onboard computer readout indicated an average
of 31.7 mpg. These numbers were influenced by slow-moving traffic from
Stuttgart to Gmuend. The thirst increased quite a bit on day two, but
despite Roehrl's habit of pushing the engine to its 7800-rpm fuel
cutoff, there was no need for a second pit stop. Surprisingly, the
elevated rev level does not seem to affect consumption. The 3.8-liter
flat six needs 7400 rpm to dish up 400 hp, which compares to 385 hp at
6500 rpm for the old engine. Perhaps even more significant is the shape
of the torque curve; it now peaks at 5600 rpm, where 325 lb-ft of torque
is on tap. In the previous car, 4400 rpm was enough to produce 310
lb-ft. The same high rpm ceilings apply to the base Carrera engine,
which has been downsized from 3.6 to 3.4 liters but nevertheless has
gained 5 hp and a claimed sixteen percent in efficiency.
Roehrl
and Achleitner whipped the new 911 through the historic hunting grounds
with so much verve and ambition that Ferry Porsche would have been
proud. Although the passenger seat was definitely the second-best place
for this experience, I was able to learn a lot about the new car's many
virtues and few vices. Perhaps the most significant dynamic asset is the
almost total absence of understeer. The 997-series 911 would grab every
opportunity to shy away from the apex. Only the very brave -- or stupid
-- pushed the 997 into oversteer. Mastering the monster made you feel
like a hero, but the 997 was never quite as quick as this incredibly
balanced 991-series 911.
When
we asked Roehrl to put in a couple of sideways stints, his face lit up
and he instantly shifted down a gear or two. But we soon found out that
this 911 is now a talented carver, no longer a casual slider. "This
can't be true," he said. "Maybe I need first gear. No, we're running out
of revs much too soon. Second then, perhaps, let's try again. Go, go,
go! Still does not want to do it. Just does not want to do it. Maybe
it's my driving style. I always need to have the car absolutely straight
again at the exit of the bend. That's better now, much better. But I
was expecting more attitude, much more attitude." It was not to be.
According to Achleitner, tail-out mode is not only counterproductive,
"it also is no longer part of the car's character the way it was in
older 911s. The 991 is more communicative than its predecessors, but it
is never tail-happy. It won't lose its temper, preferring to deliver
rather than to show off. Don't forget, however, that this is only the
first chapter of an even more complex story. Although there will be
sharper and faster variations of the theme, accessibility remains a
prime objective."
Of
course, this Porsche is not devoid of flaws, but at this point it's
difficult to decipher them. The front suspension of our example felt a
bit stiffer than it should; Sport Plus again makes sense only on the
racetrack, where its extreme calibration pays off; the stability control
system still lacks a user-friendly in-between mode; there is no
indicator to alert you that you are in coasting mode; and the long
options list lacks any camera-based driver-assistance systems. In a
nutshell, there is not much to complain about but plenty of reason to
wax lyrical. After all, this 911 epitomizes the fine art of evolution.
It is both trendsetting and tradition-conscious, and it is a promising
sequel to one of the planet's greatest sports cars.
