2009 Porsche 911 Carrera and Carrera S

Despite Porsche’s grandiose maneuvering
to take over Volkswagen, Europe’s largest car company, the tiny
The most important changes are in
the engines: Both the standard 3.6-liter six and the 3.8-liter S version move
from port to direct fuel injection. By injecting the fuel directly into the
cylinder at a pressure of up to 1740 psi, the intake charge is cooled very
effectively when the fuel atomizes. This allows the compression ratio to be
increased to 12.5:1 and for a little more air to be sucked into the engine with
each intake stroke. More air means more power, and higher compression aids both
power and efficiency.
In addition, the construction of the
water-cooled flat-six has changed to eliminate four major parts and improve
cooling and stiffness. There’s also an improved lubrication system [see Tech Highlight] that lowers the engine 0.4 inch, along with a
more compact intake manifold, lighter tappets, and bigger bore and shorter
stroke dimensions.
As a result, horsepower in the
3614cc base engine jumps 20, to 345, and torque grows from 273 to 287
pound-feet. The 3800cc S engine goes from 355 to 385 ponies and from 295 to 310
pound-feet. The bigger increases in the S engine come from larger valves,
greater valve lift, and a two-stage intake manifold.
Both engines come with the current
six-speed manual, but for an extra $4080, a new PDK transmission can be ordered, replacing the previous
Tiptronic option. This is a double-clutch gearbox with seven speeds, and it can
operate automatically, in a variety of modes, or manually via the shift lever
or switches on the steering wheel.
Top gear in the PDK gearbox is much
taller than in either the six-speed manual or the old five-speed Tiptronic for
lower rpm on the highway. European tests show the PDK to be about 12 percent
more fuel efficient than last year’s Tiptronic and even thriftier than the
manual.
Porsche says the PDK-equipped car
accelerates to 60 mph a full second faster than the Tiptronic when coupled to
the optional Sport Chrono package, which comes with launch control.
Other key additions to the ’09
models include a larger touch-screen LCD panel, standard bixenon headlights
(with optional cornering function), LED taillights and daytime running lights,
bigger front brake rotors and stiffer calipers on the base model, and an
optional new PASM sport suspension that lowers the car 0.8 inch.

Except for exhibiting a tiny
hesitation when moving away from a stop, the PDK gearbox is as smooth as a
torque-converter automatic, yet it has the tight connection between engine and
rear wheels that makes a manual transmission so satisfying. Unfortunately, the
PDK doesn’t ever relinquish full control to the driver. Even in the manual
mode, the transmission will kick down and upshift at the redline if you mash
the accelerator to the floor and hit the kickdown switch.
The shift controls on the steering
wheel are also a bit odd, not being quite as convenient for upshifts as we’d
like. But if the driver selects the “sport plus” mode, the PDK will slam the
shifts hard and unfailingly select the correct gear for the circumstances.
Base prices for the new models,
which arrive this month, range from $75,600 for a standard Carrera coupe to
$96,800 for a Carrera S Cabriolet. Four-wheel-drive versions will follow
shortly after. As always with Porsche, the prices are high, but if you can
afford the cars, you won’t be disappointed.
