But, one major point in the mild hybrid vs. plug-in hybrid (PHEV) comparison is that a mild hybrid recharges via regenerative braking. PHEV models use regenerative braking, too, but the real difference, as the name suggests, is that you can plug one into a charging station to recharge the battery directly.

The mild hybrid, also known as MHEV or the integrated started generator (ISG), is a powertrain that utilizes both a combustion engine and an electric motor to minimize CO2 emissions, improve the fuel economy and provide performance benefits.

The mild hybrid system delivers great fuel economy benefits on some of our most popular models. For example, on the XC90, fuel economy figures jump by as much as 2 MPG in both city and combined in our 2023 XC90 B5 AWD.

Mild hybrid cars offer slightly better fuel economy and lower emissions than normal petrol or diesel cars. They can also offer a slight acceleration boost too.

Is a mild hybrid car worth it? Depending on your priorities, a mild hybrid car could be a great choice. They offer better fuel economy and lower emissions. While you won't get the zero emissions of an electric vehicle or even of a full hybrid, it's definitely a step in the right direction compared to a traditional car.

Unlike the mild hybrid, a full hybrid will allow you to travel short distances - usually no more than a mile or two - under electric power alone, letting the engine shut off briefly and save you fuel.

A Volvo mild hybrid model's ride is refined, as it will allow for an instant start and no more lurching from a standstill. The electric battery also gives the vehicle a little more power off the starting line, as you will see when comparing hybrid and non-hybrid models.

Cons of Mild Hybrid Vehicles:

• Like other hybrid vehicles, you'll probably pay more for insurance.
• You won't save as much money driving a mild hybrid versus a full hybrid and EV.
• You have two engines - gas and electric - so repairs will be higher than a gas car.
• There are no federal tax credits for a mild hybrid vehicle.

Typically, leading hybrid car manufacturers like Honda and Toyota state that hybrid batteries last between 80,000 to 100,000 miles. But with regular maintenance and servicing, some hybrid car owners claim their batteries have lasted up to 200,000 miles!

The main difference is that while a normal hybrid car can run on electric power alone, a mild hybrid cannot. The mild hybrid system just works alongside the petrol engine to provide a boost of performance and economy.

How much does a hybrid battery cost? Generally, a hybrid battery replacement cost can range from $2,000 to $8,000.

The batteries used in 48-volt mild hybrid systems are also considerably smaller than a standard hybrid's. As a result, they cost far less to replace if they fail. Some batteries cost as little as $1,000, and prices may continue to fall as manufacturers develop more efficient ways to produce them.

If the 12-volt battery system fails, the petrol engine will be unable to start and that will also generally put a stop to play even if the high-voltage batteries are fully charged. Some hybrids such as the Toyota Prius give you three attempts to start the petrol engine after which, the car actually needs to be reset.

Hybrid Battery Life Expectancy Most hybrid batteries should take drivers about 100,000 miles. With excellent maintenance, some owners are able to push this number to 200,000.
