Its sport-tuned suspension, adaptive dampers, and limited-slip differential work together to provide crisp handling and minimal body roll. This makes it a joy to drive on twisty roads, where it feels planted and confident. The Si's performance is a well-rounded package that caters to driving enthusiasts.

This technology allows the car to provide a comfortable ride on smooth surfaces while firming up for more spirited driving.
