The updated 2021 Volvo S90 and V90 will feature hybrid technology.

Volvo's current 90-series sedans and wagons have reached the midpoint of their life cycle, and the automaker has introduced a series of updates to keep them fresh.

The changes are nearly identical to those announced last year for the 2020 XC90, affecting both the exterior and the mechanicals.

The big news is that mild hybrid technology is now available for all models. This is essentially a belt-driven motor-generator that recovers energy during braking and stores it for later use, such as starting or assisting the engine. According to Volvo, this system can reduce fuel consumption by up to 15%.

Another notable change is that the name of the plug-in hybrid model has been changed from conventional twin engine to recharge. This means that the existing S90 T8 twin-engine sedan will be classified as the S90 Recharge T8 in an updated form. Volvo also uses Recharge to denote the battery-electric model, which now consists only of the XC40 Recharge.

In the U.S., the 90 Series currently has a 316 hp, 295 pd-ft T6 and a 400 hp, 472 lb-ft T8 twin engine. Presumably, the same models will be offered in the updated 90 Series.

Outside the vehicle, there is a new design for the lower front mask across the range; on the V90 and V90 Cross Country Wagon variants, the taillights have also been redesigned. New color options and wheel patterns will also be available.

Interior changes are even harder to find. In addition to an improved Bowers and Wilkins audio system featuring upgraded amplification and noise cancellation, there is a sensor-based air purifier that allows the driver to monitor air quality through the infotainment system. A USB charging point replaces the 12-volt outlet in the rear and allows wireless charging of mobile devices. Premium models are also available with leather-free trim.

The updated S90 and V90 will be in showrooms later this year as 2021 models. Specific details for the U.S. market will be announced closer to market launch.
