General Information
The model year 2010 911 Turbo will receive a completely newly developed engine based on the naturally aspirated engine of the 911 Carrera 2nd generation. The displacement has been increased from 3.6 l to 3.8 l compared with the previous Turbo model.
The engine still retains the following important basic characteristics:
- 6-cylinder horizontally opposed engine
- Turbocharger with variable turbine geometry (VTG)
- 4-valve technology with hydraulic valve clearance compensation
- Intake camshaft control and valve lift adjustment (Vario-Cam Plus)
The development objectives for the new 911 Turbo engine were:
- Increased power and torque over the entire engine rpm range
- Reduced fuel consumption and CO2 emissions
- Improved responsiveness
- Extended usable engine rpm range
- Reduced system weight to increase performance
These objectives were achieved with the following new features and enhancements:
- Completely new, weight-reduced basic engine
- Increased displacement from 3.6 l to 3.8 l
- Direct fuel injection
- Weight-reduced valve and timing drive mechanism (to increase the maximum engine speed from 6750 rpm to 7000 rpm)
- Overboost function with higher maximum torques (in combination with the optional Sport Chrono Package Turbo)
- Cylinder heads with tumble intake ports
- Expansion intake manifold
- Integrated dry-sump lubrication
- Electronic demand-controlled oil pump
