S90/V90 styling is attractive, and cuts wind drag at speed. Under the clean lines are a strong chassis and competent suspension. The 2.9-liter inline six produces its power and torque peaks at low rpm for better driveability. What's the S90/V90 got going for it? A full load of standard equipment, for starters. Leather interior, alloy wheels, power sunroof, antilock brakes, automatic climate control, premium sound system, heated exterior mirrors, dual power seats and a multitude of power accouterments are all included in the base price. Rear-wheel drive for better balance and dry-weather handling is a plus.
