MHEV and Hybrid 48 Volt Vehicles, Testing, Repair and Rebuild
Major car manufacturers using 48V mild hybrid technology (MHEV) include BMW, Mercedes-Benz, Audi, Volvo, Hyundai, Kia, Ford, and Jaguar Land Rover. The system replaces the traditional 12V system, using a 48V battery and motor-generator to improve fuel efficiency, reduce emissions, and provide extra torque during acceleration, with many new models using it as standard.
Key Manufacturers and Examples:
BMW: Widely implemented in models like the X3, X5, X7, 3 Series, and 4 Series.
Mercedes-Benz: A leader in this space, using it on cars such as the C-Class, E-Class, S-Class, and GLC.
Audi: Utilizes 48V in models like the A6, A7, A8, and Q7.
Volvo: Features this technology in vehicles like the XC40 and V60 Cross Country.
Hyundai & Kia: Used in models like the Hyundai Tucson, Santa Fe, and Kia Sportage/Ceed.
Ford: Used in the Ford Puma and other models.
Jaguar Land Rover: Extensively used in the Jaguar XE and Range Rover lineup, including Defender, Range Rover, Evoque, Velar and Range Rover Sport for example.
Other/Future Adoption: Stellantis (via Peugeot/Fiat), Proton, and Tesla (for the Cybertruck/future vehicles) are adopting or utilizing 48V systems to enhance efficiency and reduce power demands.
The 48-volt system works by supporting the combustion engine, offering quieter stop-start functionality, and powering electrical components, which helps increase power by over 10 horsepower in some models while aiding in better mpg.
MHEV Testing, Repair and Overhaul Specialists
Many 48v vehicles are now suffering with failures of modules such as DCDC Converters, Lithium Batteries, Alternators, Starter/Alternators BeCM and all manner of control modules that are rarely understood by regular garages and workshops.
Turners are specialists in 48v systems and are regularly contacted by ordinary garages and even main dealers to assist with problem vehicles.
We repair most 48v control units in-house and offer testing for DCDC converters, alternators, starter/alternators and batteries.
We can test, charge, equalise and rebuild lithium and other 48 volt batteries. We even offer 48 volt chargers and testers to the motor trade.
You can book your MHEV or 48 volt vehicle system into our workshop or alternatively send components to us for testing and repair, please email us at
