Sixth generation - Engines

The 3.6-litre boxer engine in the 997 Carrera now delivered 325 PS, and the newly developed 3.8-litre engine of the Carrera S produced 355 PS. This made the 997 the first 911 since 1977 to be offered with naturally aspirated engines with two different displacements and performance levels. In 2006, Porsche presented the 997-generation 911 Turbo. This was the first series-production car with a petrol engine to use a turbocharger featuring Variable Turbine Geometry (VTG). From the 2006 model year, Porsche offered a power increase to 381 PS exclusively for the 3.8-litre S models. After the model update in autumn 2008, Porsche offered the 911 with petrol direct injection and an optional dual-clutch transmission (PDK), which made the 997 even more efficient and powerful. More economical driving was made possible by enhanced boxer engines with an extended service interval of 30,000 km. With its 3.6-litre boxer engine the Carrera now delivered 345 PS, and the 3.8-litre managed 385 PS. In the new 911 Carrera GTS, which closed the gap between the Carrera S and the GT3, the boxer delivered 408 PS. In the 911 Turbo with a displacement of 3.8 litres, 500 PS was available, and the Turbo S even reached 530 PS. The top model was the 911 GT2 RS with 620 PS. The performance breadth of the 997 was the greatest ever for a 911.
