A plethora of Volvo’s 2022 models will be offered with 48-volt mild-hybrid powertrains in the U.S.
These models will feature B5 and B6 badges and be used by the 2022 S60, S90, XC60 and V90 Cross Country and will replace the non-hybrid T5 and T6 powertrains. Data from the Environmental Protection Agency (EPA) confirms that the 2022 S60 B5, for example, returns 26 MPG city, 35 MPG highway, and 30 MPG combined, compared to the 23 city, 34 highway, and 27 combined of the outgoing 2021 model.

Volvo already sells its B5 and B6 powertrains in other markets. Both use a 2.0-liter four-cylinder that is turbocharged in B5 guise while the B6 variant is both turbocharged and supercharged. The B6 powertrain will be available as an option on the XC60, Car and Driver reports, and standard in the S90 sedan and V90 Cross Country wagon.
Details for the U.S.-spec models haven’t yet been confirmed, but the B5 model sold in Europe has 247 hp, slightly less than the T5 powertrain with its 250 hp. Similarly, the B6 is rated at 295 hp in Europe compared to the 316 hp of the T6.
For the XC60, fuel consumption data reveals that the B5 model provides a 1 MPG increase over the city cycle compared to the T5. Similarly, the higher-powered B6 is 1 MPG better in the city and 1 MPG more efficient over the combined cycle compared to the 2021 XC60 T6.
