Overview

The 957 Cayenne S uses a larger naturally aspirated 4.8L V8 that delivers stronger torque and a broader powerband than the earlier 4.5. Tuning improves the urgency of the V8, cleans up throttle mapping, and helps the heavy Cayenne feel lighter on its feet.

Key Features

  • Sharper naturally aspirated response
  • Stronger midrange punch
  • Improved throttle calibration
  • Better power delivery in a heavy chassis
