In 2017, Volvo entered the luxury sedan market with its flagship four door, the S90. Its prominent mid body line and classic shape reinforce the brand's heritage while its sedan body offers a fresh and contemporary look. The S90’s Recharge variant uses the Volvo XC90 Recharge’s plug-in drivetrain. The S90 Recharge will run on smooth, silent electric power for about 38 miles before the gas engine takes over. The “twin engine” drivetrain mates the S90’s electric motor to a 2.0-liter, four-cylinder that is both supercharged and turbocharged, improving fuel efficiency while giving the engine plenty of power throughout its RPM range. The gas engine drives the front wheels while the electric motor powers the rear axle. Adding to the S90 Recharge’s overall efficiency is Volvo’s crankshaft-integrated starter generator, which starts and charges the car and seamlessly transitions between the vehicle’s gas engine and electric motor. The system also provides additional power to eliminate lag before the supercharger and turbocharger kick in.

The interior's Scandinavian-style design is uncluttered and sophisticated. Volvo’s soft Nappa leather seats wrap around safety features designed to prevent spinal injury in the event of a severe crash. A central nine-inch center touchscreen provides easy and intuitive access to all of the car’s infotainment and climate control features. Vertical air blades on the vents, Orrefors crystal in the shift lever, and diamond-cut metal on the knobs are subtle flourishes in the S90 Recharge’s otherwise serene cocoon.
