New Car: 2010 Porsche 911 GT3


If the 911 is the quintessential Porsche, then the weight-optimized and more powerful—yet naturally aspirated—GT3 is the quintessential 911. But its aficionados needed patience; while the more humble versions of the 911 were updated last summer, the GT3 and Turbo have soldiered on without changes.
Now, Porsche has released pictures and information on the latest GT3, which debuts at the Geneva auto show in March. The Turbo will have to wait until the Frankfurt show in September, and then it may still be some time before the Turbo Cabriolet and the Turbo-based GT2 are updated. Porsche clearly intends to keep us busy.
Changes to the GT3’s exterior are subtle but clearly recognizable. Front LED daytime running lights and LED taillights are taken directly from the regular 911. The exterior mirrors have grown in size to conform to upcoming European regulations. We think the front has lost some of its aggressive edge. Two vertical strips in the lower central air intake are now painted black and thus seem to vanish; the small air intake just below the hood now is body colored to blend in more smoothly. The rear end, on the other hand, gets additional horizontal slits for ventilation. The provocative spoiler looks less stylized and more business-like, the GT3’s business being racing. The vertical slits on the extreme corners of the rear bumper are now uninterrupted—again, for a cleaner look.
The styling changes make sense insofar as they bring about aerodynamic improvements. Porsche says total downforce has been doubled. The wheels are now of the super-cool center-lock variety and weigh less than those they replace. Porsche’s active suspension remains standard.
Power output rises from 415 to 435 hp, achieved mainly by increasing displacement from 3.6 to 3.8 liters. The exhaust camshafts are now adjustable with Porsche’s VarioCam variable valve-timing system; previously, only the intake camshafts were so equipped. Porsche’s goal was to improve mid-range torque, but sheer performance figures have been improved as well: 0-to-60-mph times drop from 4.1 to 4.0 seconds, and 0–100 mph comes in 8.2 seconds, down from 8.7. Top speed climbs ever so slightly from 193 mph to 194 mph. The GT3’s engine still has true dry-sump lubrication and is still related to the motor in the Turbo; this family is distinct from the series powering other naturally aspirated 911s.
Porsche has been savvy enough to recognize that the cool-looking GT3 is not bought exclusively by experts and racers. To make the GT3 safe even for clumsy drivers, the stability control system is available on this 911 version for the first time. Beware: Once it’s turned off, there is no safety net. Unlike with other 911 models, PSM does not reintroduce itself when you hit the brakes—unless you push the button again very quickly (not something we’d recommend trying mid-skid). The GT3's standard brakes are larger, lighter, and better-ventilated, with carbon-ceramic discs continuing as an option.
Porsche has come up with two more innovations that make sense to us: An active drivetrain mount—called PADM—recognizes racing conditions and stiffens the engine mounts, which are usually elastic to keep the GT3’s chassis comfortable in normal driving. And there is an optional lift, similar to the Lamborghini Gallardo’s system, that lets you raise the front end by just over an inch. It keeps your chin spoiler happy on poor roads or when encountering a steep bump. Porsche is considering offering the system on other 911 versions but wants to prove it on the low-volume GT3 first.
What the GT3 doesn’t get: A dual-clutch transmission, which would be out of place in this racer, and, surprisingly, the automaker’s direct-fuel-injection technology. Expect future GT3 models to switch to the fuel-saving technology.
Europe gets the new 911 GT3 in May, but we will have to wait until October. It will be priced at $112,200 when it hits the States, a $4700 over the current model.
