Power for the 2007 Volvo XC90 V8 Sport comes from brand's transversely-mounted 4.4-liter, dual overhead cam V8 that pushes 311 horses at 5,850 rpm and 325 lb.-ft. of torque at 3,900 rpm. Fuel economy is EPA-rated at 15 mpg city and 21 mpg highway, aided in part by a standard six-speed automatic transmission. Behind the scenes is a suspension that's been tweaked with stiffer shocks and larger stabilizer bars to provide a sportier response. Likewise, the steering has been tightened up for improved response. A self-leveling suspension is also featured on the 2007 Volvo XC90 V8 Sport.
