The 2007 Volvo XC90 SUV is available with three rows of seating for up to 7 passengers and with two different engines. Gone is the entry-level inline five-cylinder, replaced by the previously optional 3.2-liter, 235-horsepower six cylinder that gets 17 mpg city, and 22 mpg highway. At the top of the range is a 4.4-liter V8 good for 311 horsepower, as well as 15/20 mpg. Both engines come mated to a six-speed automatic transmission. Volvo pioneered rollover stability control with the XC90, which senses and stops a rollover before it occurs. The XC90 comes equipped with standard front side airbags and curtain airbags for all three rows.
