The New Subaru Impreza XV
Inside the Subaru WRX STI Sedan
The US model is powered by a 305 bhp turbo boxer paired to a 6-speed manual. The STI comes with Multi-Mode Driver Controlled Center Differential (DCCD) with three Auto modes, as well as a manual mode with six driver-selectable differential locking settings.
Both the front and rear suspension systems employ higher-rate springs and thicker front and rear stabilizer bars than the 2010 model: 21 mm vs 20 mm in front and 19 mm vs 18 mm at the back. Spring rates are up by 15.6% up front and 53% behind. Ride height has been lowered too. The standard 18-inch aluminum wheels are lighter too, but many will take the optional BBS forged aluminum-alloy wheels
