The 2007 Volvo XC90 is a luxury midsize SUV offering a host of comfort and safety features. Available in three trims: the 3.2, the V8 and the V8 Sport, the 3.2 trim is powered by a 3.2-liter inline six-cylinder engine that produces 235 horsepower, while the V8 trim has a 4.4-liter V8 that generates 311 hp. Both engines are mated to a six-speed automatic transmission with manual shift control. Notable safety features include antilock disc brakes, stability control with anti-roll control, front-seat side airbags, full-length head curtain-type airbags, and anti-whiplash front head restraints. Volvo also introduced a tire pressure monitor for the 2007 model. Other standout attributes include an ultra-comfortable ride quality and the availability of an optional navigation system with a screen that pops up from the dashboard.
