Fifth generation - Engines

Porsche engineers developed a completely new engine for the 996. With a displacement of 3.4 litres, the six-cylinder boxer engine – now water-cooled – delivered 300 PS thanks to its four-valve-per-cylinder layout. After the model update in 2002, a displacement of 3.6 litres delivered 320 PS, and the ‘40 Years of Porsche 911’ anniversary model even managed 345 PS. The 911 Turbo (from 2000) was also given a new, water-cooled boxer engine. Two turbochargers enabled it to deliver 420 PS, making this 911 Turbo the first series-production model from Porsche to break the 300 km/h barrier.

In the 911 GT2, the engine delivered up to 462 PS. For all series Carrera models and the Turbo, Porsche therefore offered an increase in power. Porsche also developed the 911 GT3 as an uncompromising sports car with 360 PS and a naturally aspirated engine. This was introduced from 1999 on. From 2004, the 911 GT3 RS with 381 PS was added to the range as a homologation model for motorsport.
