Track Tested: 2010 Porsche 911 GT3 vs. 2010 Porsche 911 Turbo


2010 Porsche 911 GT3 vs. 2010 Porsche 911 Turbo

Edmunds.com tests hundreds of vehicles a year, but not every vehicle gets a full write-up. The numbers still tell a story, though, so we present "Track Tested." It's a quick rundown of all the data we collected at the track, along with comments direct from the test drivers. Enjoy.

When it comes to track stars, these are two of the finest you'll ever see. Actually, you may never see either of these cars, as their prices guarantee a certain level of exclusivity. On the "low" end is the 2010 Porsche 911 GT3 at $112,200. Seems expensive until you realize that the 2010 Porsche 911 Turbo starts at $132,800.

A bit steep, yes, but these are cars that make those prices seem almost reasonable given what you get. Consider that the Turbo turned in the quickest quarter mile we've ever recorded. And the GT3 wasn't far behind. Both deliver nearly untouchable performance, yet they go about it in slightly different ways.

The GT3 is the raw track car: rear-wheel drive, minimal weight and a manual transmission. If all you want to do is go fast on weekends, there's no reason to look any further. The Turbo is the ultimate GT. All-wheel drive, a seven-speed dual-clutch transmission and all the luxury you would expect in a six-figure sports car. Oh, and it's blindingly fast, too. How fast? See for yourself on the next page.

Acceleration Comments: Difficult to achieve perfect launch with this much power and grip. Fortunately, the GT3 has a nearly indestructible clutch. It demands deliberate shifts and doesn't care about being beaten on during acceleration testing.

Braking Comments: Outstanding pedal feel and stopping distances. Feels like it could do this all day.

Handling Comments: Slalom: Not a gentleman's Porsche. Rather, a potent, communicative, immediate and somewhat intimidating Porsche that demands respect and delivers a proper reward to those who treat it properly. Skid pad: Won't lift-throttle oversteer at this speed, but nonetheless generates outstanding numbers. Again, rewarding if you can master it.

Skid Pad Lateral Acceleration (g): 0.97
Handling Rating: Excellent
Db @ Idle: 54.2
Db @ Full Throttle: 86.4
Db @ 70 mph Cruise: 74.0

Acceleration Comments: Holy crap! This is fast. And the amazing part? It could easily be faster. A surface with more grip would allow the PDK to hold 1st and 2nd gears longer and likely yield quicker times. Here, it just upshifts immediately when it senses wheelspin. PDK is, again, amazing. Launch control produced the best run.

Braking Comments: Perfect feel, confidence and impressively short stops.

Handling Comments: Slalom: Lively to the point of big slip angles even with PASM on. Therefore, I prefer the confidence of stability control in fast transitions. Skid pad: Likes stability control in this situation. It's receptive to lift-throttle, perhaps due to individual brake application. Too stiff in its hardest suspension setting -- both here and in the slalom.
