The power is sent 41:59 front to rear and depending on driver inputs, power can also be sent side-to-side.

The interior STI comes standard with Alcantara seats with red and black leather bolsters and red stitching and a flat-bottom steering wheel. Dual-zone climate control, heated seats, heated exterior mirrors and heated windshield wipers are standard. There is an optional navigation system with a 6.1in LCD screen.
