Vitesco powered M-Two side-by-side vehicle showcased at EICMA 2023
The German Tier-1 major which is part of automotive giant Continental is bullish about the demand in the side-by-side and utility vehicle segments.
German Tier-1 supplier of advanced powertrain solutions, Vitesco Technologies, says its integrated electric axle drive EMR3 (3rd generation Electronics Motor Reducer), is powering the M-Two electric side-by-side vehicle (SSV), showcased by German's Mandrill, a leading player in the e-off-road segment.
The demo vehicle – a prototype that is already being used for test drives – is powered by the highly-integrated e-axle, which Vitesco Technologies has already put into series production in more than 20 passenger car vehicles by European and Asian manufacturers since 2019. The Mandrill 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. According to Torsten Bellon, Head of the Two-Wheeler & Powersports product line at Vitesco Technologies, “Based on the many talks we are having with customers regarding electrification in the powersports sector, we expect a strong increase in demand for electric drives in this segment.”
In the development of solutions for the two-wheeler or off-road segment, he adds, the company has the considerable advantage of having access to in-house automotive products. “And when adaptations or further developments are required, our more than two decades of expertise in two-wheeler and powersports applications really comes into play,” Bellon said.
“We are pleased to present Mandrill’s M-Two, the first application of the EMR3 in the off-road segment. It is impressive proof that our automotive background enables us to serve the growing global demand for electrification in this market, which is especially large in North America, with ready-to-use, proven solutions. We are also considering giving our customers access to individual components of the e-machine for future EMR generations.”
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 company claims 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.

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.
