- The new 48-volt system will be called “mild hybrid”
- Not to be confused with T8 Plug-In Hybrid models
- It’s not a plug in system
- It was offered on US 2019 XC60 and XC90 SUVs
- It will be available on all 2021 Volvos
The new system Volvo calls “mild hybrid”. It’s a 48-volt system that doesn’t have plug-in support, rather it uses regenerated electricity from braking.
Because the new system isn’t a plug-in, it’s obviously not to be confused with Volvo’s T8 Plug-In Hybrid powertrain option that has been available on most Volvos since the 2016 XC90 (second generation XC90).
On the new system, the recaptured energy charges up a battery, which then powers an integrated starter generator. The generator in turn helps the combustion engine temporarily, which lowers emissions, and it also powers the car’s stop/start system.
This update means Volvo will have three levels of electrification: this new mild hybrid, the aging T8 Plug-In Hybrid, and the new, almost-available-to-buy XC40 Recharge.
