Regensburg, November 7, 2023. Vitesco Technologies, a leading international supplier of advanced powertrain technologies and solutions for e-mobility, is presenting a world premiere at EICMA 2023 (November 9-12, press and trade visitor days on November 7-8): The M-Two electric SSV (side-by-side vehicle) by German manufacturer Mandrill, one of the pioneers in the e-off-road market. The demo vehicle – a prototype that is already being used for test drives – is powered by the highly integrated electric axle drive EMR3 (3rd generation Electronics Motor Reducer), which Vitesco Technologies has already put into series production in more than 20 passenger car vehicles by European and Asian manufacturers since 2019. The all-wheel-drive vehicle uses one EMR3 each on the front and rear axles. Another component from the passenger car sector is the PDCU (Powertrain Domain Control Unit), which the two-wheeler and powersport specialists at Vitesco Technologies have further developed for use in the M-Two. The company anticipates significant growth in electric off-road vehicles such as SSVs and also UTVs (Utility Task Vehicles), which are SSVs where the main focus is utility.

Compact, powerful, and robust axle drive 

The EMR3 is a compact, lightweight unit that consists of a permanent magnet synchronous motor, power electronics (inverter) and a reduction gear (reducer). This scalable electric drive mobilizes up to 150 kW of power and a torque of up to 2,900 Nm, weighs only 76 kilograms, and its dimensions (40 x 35 x 55 cm) are barely larger than a piece of carry-on luggage. The highly integrated system does not need any internal plugs or cables when connecting the motor and inverter, which also contributes to its robustness.   

The automotive axle drive was integrated in the M-Two with no modification required. For this purpose, the off-road specialists at Vitesco Technologies further developed the PDCU control unit to allow the software integration of the EMR3 in SSV applications. Here, the PDCU serves as an interface box containing full functionality and can be adapted to the specific purpose of the off-road vehicle. Compared with their use in passenger cars, the software adaptations required included the development of special algorithms, for example for torque management. Since two EMR3s are used in the M-Two, CAN communication between the PDCU, the two motors and the battery is very complex.  

100 km/h in 2.3 seconds and sights set on the Dakar Rally 

Mandrill Automotive GmbH develops high-performance electric SSV vehicles for industrial and powersport applications. The forerunner of the M-Two is the prototype M-One, which has been in use as a test and promotion vehicle since mid-2021 and received road approval in May 2022. “Mandrill is pleased to have Vitesco Technologies, one of the leaders in electric drive systems and components, on board. Together we will set a milestone in the completely new segment of electric SSV and UTV vehicles,” said Heiko Bölstler, CEO of Mandrill. “Our vehicles are designed to perform in tough conditions in extreme terrain, whether at minus 30 degrees in a ski resort equipped with a track set, in the desert at 45 degrees, or climbing vast inclines with a full load. The best components on the market were selected for this, and these include the Vitesco Technologies’ EMR3 unit.”  

Unlike conventional SSVs the M-Two does not need a drive belt because both axles are driven directly by an EMR3. The all-wheel drive vehicle therefore also provides its maximum output of 150 kW in pure rear-wheel drive. The total torque of 5.800 Nm catapults it to 100 km/h in 2.3 seconds (top speed: 135 km/h). The 43 kWh battery (400 volts) provides a range of up to 300 kilometers and can be charged to 80 percent in 30 minutes.   

The waterproof off-roader (to IP67/69 standard) will initially be launched in Germany, Austria, and Switzerland. From 2025, Mandrill plans to market the vehicle worldwide, including in North America, the main market for SSVs. The company has also received inquiries from teams who would like to deploy the M-Two in the Dakar Rally.
