Fuel and Ignition System

General Information - Engine Type M97.01

The 3.8 liter engine of the 911 Carrera S (997) is designed for a high specific output with a high torque over a wide rpm range as well as for very low emission levels and consumption values. The fuel/air mixture is electronically controlled by the Motronic control module ME 7.8.

Development goals for the 911 Carrera S:
- High specific output
- High torque over a wide rpm range
- Reliable fulfilment of all statutory emission demands
- Low specific fuel consumption
- Unique Porsche exhaust note
- Reduction of maintenance costs
- To offer an additional 911 Carrera S model with even greater performance thanks to a new engine with a significantly higher equipment level than the basic model

911 Carrera S

The 911 Carrera S has a newly developed 3.8 liter engine and is essentially based on the 3.6 liter engine of the 911 Carrera. An increase in displacement and extensive fine-tuning work, particularly on the gas cycle, has resulted in a maximum output of 355 bhp (261 kW) and a maximum torque of 295 ft lbs (400 Nm). The high specific torque of 77.3 ft lbs (104.6 Nm)/l (911 Carrera 3.6: 76 ft lbs (102.9 Nm)/l) and the balanced torque curve of the 3.8 liter engine, which is considerably above the values of the 3.6 liter engine across the rpm range, facilitate better performance and superior flexibility.

The engine is characterized by the unique Porsche exhaust note and fulfills the emission demands EU4 or LEV (USA).
