The 2022 Volvo S90 comes with two powertrain options that deliver power satisfactorily to give the driver a smooth, quiet, and comfortable drive. The base engine is a supercharged and turbocharged 2.0-L I-4 engine with a power output of 295 hp and 310 lb-ft of torque. This engine variant is coupled with a mild hybrid system of 48 volts to give it a higher efficiency level and power.
Another available powertrain is the turbocharged and supercharged 2.0-L engine with two electric motors delivering 400 hp and 472 lb-ft of torque. The primary drivetrain is all-wheel drive, while the transmission is an eight-speed automatic. The standard powertrain of the S90 has the most powerful base engine in its class, with punchy acceleration and a smooth transmission. Volvo has improved the stop/start operation to make it nearly undetectable, and the vehicle is quicker and more responsive than previous models.
