Video: 2014 Porsche 911 GT3 at Goodwood 2013

The 2014 Porsche 911 GT3 recently made its dynamic debut at the Goodwood Festival of Speed 2013 and Porsche has put together the following short clip of the car running up the legendary Goodwood hillclimb. Making the GT3’s run all the more impressive is the fact that the Porsche 911 was being celebrated for its 50th anniversary at the Goodwood Festival of Speed 2013.

The Porsche 991 GT3 gets a 3.8-litre flat engine developing 475hp at 8,250 rpm. It is an adaption of the engine used in the current generation Porsche Carrera S but with only a few common parts. The engine weighs around 25 kg less than the previous unit with a power output of 125 hp/litre of displacement.

The crankshaft and valve train, were specially adapted or developed for the GT3. The GT3 uses titanium connecting rods attached to forged pistons. Performance is as follows: 0 to 100km/h is passed after just 3.5 seconds, and 200km/h in less than 12 seconds with the car maxing out at an impressive 314km/h. The lap time on the Nürburgring-Nordschleife was a very impressive 7:30 minutes. The last statistic is particularly important. Around 80 per cent of Porsche 991 GT3 customers also drive their cars on race tracks.

The GT3 features new cylinder heads with larger intake and exhaust ports, large valves, and separate valve control with rocker arm. It features valve actuation via rocker arms with hydraulic valve clearance compensation.
