Learn More About Electrified Powertrains

Volvo Cars has committed to a carbon-neutral future by 2040; the all-new Volvo Mild Hybrid System (MHEV) is one of the ways it plans to make it happen. It's all about creating sustainable mobility, but Volvo Cars has the wisdom to realize that the steps taken to achieve that goal must also be sustainable. The Volvo Mild Hybrid System allows for remaining internal combustion engines (ICEs) to have the support of battery power, which reduces engine load & carbon emissions while boosting performance & mpg. Compare the MHEV technology found on this page to the current PHEV technology in our current Volvo XC60 Hybrid inventory and see which powertrain is right for you! Read on for more.

What Is the New Volvo Mild Hybrid System?

Enhancing T5 & T6 engines, B5 & B6 propulsion systems will implement an electric motor that works in tandem with a 48-volt battery. Unlike a traditional hybrid or plug-in hybrid, the Volvo Mild Hybrid System is designed to add efficiency and power exclusively to the engine — not the transmission and drive gears. In other words, a traditional hybrid or plug-in hybrid can use electricity to physically power the wheels, whereas the Volvo Mild Hybrid System squeezes the most energy out of a traditional engine.

So that's how Volvo Mild Hybrid cars differ from other electrified Volvo vehicles. But how are they the same, if at all? Great question. Let's take a closer look at the other electrified systems and see if we can identify the unifying characteristics.

  • Volvo EV Technology - This propulsion system resembles the future of all Volvo vehicles. There is no internal combustion engine of any kind on a pure EV. All fully electric Volvo models come standard with full-time eAWD, thanks to electric motors found at each axle. Charging occurs either at home via a conventional wall outlet (Level-1 charging), at a public charging station with fast-charging capabilities (Level-2 charging), at a high-speed charging station (Level-3 charger), or through the vehicle's regenerative braking capabilities. "Regen braking" captures energy that is otherwise lost in traditional powertrains. As you slow down, regenerative braking sends "lost" energy back to the vehicle's battery.

  • Volvo Plug-In Hybrid (PHEV) Technology - As the name suggests, this hybrid battery/ICE propulsion system can be plugged into a charging source and implement regen braking just like an EV. Unlike a pure EV, Volvo Cars PHEVs use a conventional engine most of the time but can enjoy a limited range of pure EV driving on command. This range is usually sufficient for most local errands.

  • Volvo Mild Hybrid Technology - Also uses regen braking to charge up the onboard battery. The battery is paired with an electric starter/generator that aids in acceleration by reducing load on the engine. As a result, less fuel is required, and performance is enhanced with reduced emissions. No external charging is needed on a Volvo Mild Hybrid vehicle.

So there it is. If you had to point out the similarities, what would they be? All systems either significantly reduce or eliminate CO2 emissions. All models reduce or eliminate the need for fossil fuels. All variants implement a regen braking system to capture kinetic energy otherwise lost in conventionally powered vehicles.

Volvo Mild Hybrid FAQs

Now that you know more than most about the Volvo Mild Hybrid System, the next and most obvious question is, "Which models are available as an MHEV?" Volvo Cars makes the answer easy. A recent portfolio-wide upgrade uses the Belt Integrated Starter Generator (or BISG) to enhance all remaining ICE models. In other words, even if you don't get a plug-in hybrid vehicle from Volvo Cars, you'll still be getting one that benefits from electrified technology. Here are some more answers to the most common questions that our EV specialists have been getting:

What is a Mild Hybrid Volvo car?

A Mild Hybrid Volvo vehicle uses an integrated 48-volt battery to power a starter/generator that enhances the performance of a traditional engine while reducing carbon emissions.

Are all Volvo vehicles Mild Hybrid?

Yes and no. Moving forward, all new models with an internal combustion engine will have the Volvo Mild Hybrid System operating underneath. If you choose a model that is a plug-in hybrid or a fully electric vehicle, then the mild hybrid system is replaced. Check out our Volvo C40 Recharge specs for the latest model to go EV all the way!

How does Volvo Mild Hybrid work?

The Volvo Mild Hybrid System is a pairing between an internal combustion engine and a 48-volt battery. The two power sources (the engine and the battery) are linked by a belt-driven integrated starter/generator (or BISG). Without any input required from you, the BISG will perform intuitively when required to aid in acceleration or reduce engine load. This operation reduces carbon emissions, extends fuel consumption, and saves your wallet some worry, as well as the environment.

Are there any hybrid Volvo cars?

Yes and no. All Volvo vehicles that are referred to as a "hybrid" are all plug-in hybrid models. Unlike conventional hybrids (or even mild hybrids), a Volvo Cars plug-in hybrid has the unique advantage to run in fully electric mode for a certain time while also benefiting from external charging capabilities. If you want the most efficiency without having to worry about plugging anything in, then you'll find the perfect vehicle from our alluring Volvo S60 and Volvo XC60 Mild Hybrid inventory.

Which Model With the Volvo Mild Hybrid System Is for Me?

Great question! If you live in our neck of the woods, it seems like many of our customers prefer to have vehicles with the most agility. In that case, we'd recommend the Volvo S60 Mild Hybrid, which gives you the perfect blend of comfort and sport-sedan performance. All of the amenities that you've come to expect from Volvo Cars are still standard, like leather, adaptive LED headlights, autonomous braking, blind-spot monitoring, and more!

If you need a little more space and capability, then you'll want to take a look at the Volvo XC60 Mild Hybrid. This legendary family SUV is packed with wonderful features like a standard panoramic glass roof, easy entry and exit, over 22" of digital screens, and more.

The future is already here at Volvo Cars. The only question that remains is which electrified model will you claim as your vehicle of tomorrow, today?
