Test Driver Ratings & Comments

Acceleration commentsUsing the Porsche Launch Assist, the launches were inconsistent. Four of five attempts resulted in a "bog 'n go" experience. As the tires heated up and became stickier, it was more beneficial to shut off both traction and stability controls and use brain power to accomplish a good time to 30 mph. That said, I wouldn't characterize the GT2 as having turbo lag. It's still very quick prior to the boost surge at about 3,200 rpm. Luckily, each redline upshift drops engine revs to that max-attack rpm. Shifter requires commitment and high effort. Clutch is usefully firm, and offers linear (not spring-loaded) feedback.
Braking ratingExcellent
Braking commentsStunningly talkative, tremendously powerful and a little gravelly sounding. Pedal pressure -- not pedal travel -- determines effectiveness. Virtually no squat or dive under full ABS braking. Knowing it would require many stops to put useful heat into the brake system, I started with a 100-0-mph stop. Result: 99 feet on the first stop. By the third stop, it was down to 96 feet. Thereafter, it never went above 99 feet and showed no signs of fading, ever. New Inside Line 60-0 stopping distance record. Not surprised.
Handling ratingExcellent
Handling commentsThe GT2 is effectively neutral on the skid pad with a hint of understeer -- a remarkable achievement considering the 62 percent rear-weight bias. The arc can be adjusted with throttle input alone, and unlike the 2005 GT2, there's no threat of oversteer at all -- even when lifting abruptly out of the throttle. This is easily a 1.0g car on better pavement. Steering is so informative it can tell you what day of the week the pavement was poured. In the slalom, the GT2's amazing yaw response is like that of a racecar. Unfortunately, this less-than-ideal course has a slight dip at cone #3 which bumps the car off line slighly -- even in the softer of the two PASM modes. The result is that the car remains totally in control, but it arrives late at the fourth cone. Huge grip/capability and this time, it's also trustworthy.
