- Certain 2022 Volvo models will add new 48-volt hybrid powertrains, badged B5 and B6.
- EPA ratings for the 2022 S60, XC60, S90, and V90 Cross Country show a boost in city fuel economy estimates.
- All models still use a 2.0-liter inline-four engine with either a turbocharger or a turbocharger and a supercharger.
Volvo is aiming to boost fuel efficiency by bringing its 48-volt hybrid system to certain U.S. models for 2022. EPA ratings for the 2022 Volvo S60, S90, XC60, and V90 Cross Country show new B5 and B6 designations with slightly higher city fuel economy ratings than the nonhybrid T5 and T6 predecessors. the S60, for instance, rises from 23 mpg city to 26 mpg city, while the V90 Cross Country goes from 20 mpg city to 22 mpg city.
These B5 and B6 powertrains already exist in other markets, and they use the same 2.0-liter inline-four found in all Volvo models in the U.S. The S60 and XC60 are offered as standard with the B5 powertrain, which has a turbocharged version of the 2.0-liter four, while there’s a more powerful B6 turbocharged and supercharged version of the engine available as an option on the XC60 and as standard in the larger S90 sedan and V90 Cross Country wagon.
Volvo has yet to release detailed U.S. specs for this new powertrain, but the horsepower ratings for the hybridized versions of these engines may change compared with the current models. Going by European specs, the B5 could have 247 horsepower and the B6 could have 295 horsepower, compared with 250 horsepower and 316 horsepower for the existing T5 and T6 models.
Look for more info to come as Volvo releases U.S.-specific details for these new B5 and B6 designations. For now, it appears that the XC40 and XC90 SUVs and the V60 Cross Country wagon won’t receive the 48-volt system yet.
