Overview
The 997.1 Carrera S uses the larger 3.8 litre flat six and has noticeably stronger factory torque than the base Carrera. Calibration work helps the engine feel more eager off corner exits and gives the car a crisper, more immediate character across the rev range.
Key Features
- Larger displacement NA flat six
- stronger mid range than base Carrera
- sharper turn in support through better throttle modulation
- excellent with plenum and exhaust mods
