If the 996.1 911 GT3 was all about the engine, in the 997.1 completes the rest of the formula. The surgical clarity of its transmission, steering, brakes, pedal weights and heights, and overall chassis balance represented a clear step-change from its regular 997 911 siblings. But the engine was still the heart of the car, the water-cooled 3.6-liter flat-six boasting a new intake and a new exhaust compared with the 996 versions. Official output was 415 hp, though insiders admit some engines made close to 430 hp. Launched in 2006, today this is in many ways the sweet-spot GT3, way more affordable than the later 4.0.
This is the best 911 Porsche has ever made. The headline power figure and the ability to rev to 8,500 snare your attention, but the most staggering aspect of this engine is actually its tractability. Mid-range lunge is marvelous, even if the peak number of 339 pound-feet doesn't sound huge in the context of short gear ratios, lightweight, and a compact frontal area. In third gear, the way this thing flies between 4,500 and 8,500 rpm is scintillating. Plus, the utter progression of the delivery makes it vastly easier to take advantage of compared to the GT2's ridiculous turbo surge. This is one special car.
Even more powerful, faster and more dynamic than ever before, the updated 997 Porsche 911 GT3 (differentiated from the earlier with a new 997.2 designation) is about to prove its enhanced potential. The Porsche 911 GT3 now reaches an even higher standard in its two main qualities: power and driving dynamics. The naturally-aspirated six-cylinder now increased in size to 3.8 litres is 435 bhp (320 kW), up 20 bhp over the previous model. In particular, the flat-six power unit carefully upgraded for even more muscle and performance offers a significant increase in torque at medium engine speeds. Road performance is spectacular.
