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.
The 992-era 911 GT3 confirms that Porsche is prepared to go to astonishing lengths to keep the hardcore faithful happy. The engine is a naturally aspirated 4.0-litre that revs to 9,000 rm and has little in common with the unit found elsewhere in the 992 range and a lot to do with the one in the GT3 Cup car. Power is up a modest 10bhp to 503 bhp, torque to 347 ft lbs. That’s more than enough. It’ll accelerate to 62mph in 3.4 seconds. It is the best sports car on the planet.
The Touring makes sense for those who envision their GT3 more as a daily mode of transportation than a track specialist (it can do both well). GT performance is good enough for any paved road but the Touring was created for a certain type of personality. There is no other car that can invoke a sense of connection and purpose like a GT3 Touring (with a 6-speed manual transmission) can. This is the car to buy and own forever.
Porsche introduced the 991 GT3 for the 2014 model year, as follow up to the multiple 997 GT3 variants. The 991 GT3 featured a new 3.8 litre direct fuel injection (DFI) flat-six engine developing 475 hp (354 kW; 482 PS) at 8,250 rpm, Porsche's Doppelkupplung (PDK) double-clutch gearbox, and rear-wheel steering. The 911 GT3 is claimed to be able to accelerate from 0-60 mph (97 km/h) in 3.1 seconds or less, and the quarter mile in 11.2 seconds at 126 mph (203 km/h). It evolved into the 991.2 GT3 for model year 2018.
The new Porsche 911 GT3 carries the same four-litre flat engine from the GT3 RS with its power increased by 25hp for a new total of 500hp. The chassis is also redesigned and now features a rear-axle steering and a lighter construction. The Porsche 911 GT3 type 991.2 comes in at 1,430 kg when its tank is full. Although it is a bit heavier than the previous model, it still manages to reach 0-100km/h in just 3.4 seconds and reach top speeds of 318km/h. What’s more interesting here is that Porsche finally decided to switch back to a 6-speed manual gearbox (7-speed PDK is standard).
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.
