Vitesco Technologies Supplies Electric Axle Drive for High-Performance Three-Wheeler Twike 5
- First use of the highly integrated EMR3 system outside the passenger car sector, where it has already been chosen for more than 20 vehicle models
- Twike 5 combines power and efficiency: 0 to 100 km/h in 3.8 seconds, power consumption 6.9 kWh per 100 km; start of production planned for mid-2022
Regensburg (Germany), November 18, 2021. Vitesco Technologies is using its EMR3 electric axle drive for the fir st time outside the passenger car sector: The highly integrated system, which has been in production since 2019 and has already been chosen for over 20 vehicle models from European and Asian manufacturers, will drive the Twike 5. The three-wheeled high-performance vehicle is a combination of an electric car, trike and recumbent bi ke, and is scheduled for limited production from mid-2022. In the current development status, the two-seater wi ll accelerate to 100 km/h in 3.8 seconds, with a top speed of 190 km/h. In addition to this impressive performa nce, the Twike 5 is also distinguished by very high efficiency. The combined power consumption according to WL TP is only 6.9 kWh per 100 kilometers, and the combined range will be more than 400 kilometers (information based on current simulations, depending on the selected battery variant).
The third generation of the EMR (Electronics Motor Reducer) is a compact, lightweight unit that consists of a permanent magnet synchronous motor, the 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 kilo grams, and its dimensions (40 x 35 x 55 cm) are barely larger than a piece of carry-on luggage. The highly inte grated system does not need any plugs or cables when connecting the motor and inverter, which also cont ribut es to its robustness.
“The integrated electric axle drive from Vitesco Technologies is an innovative yet fully developed technology, as shown daily by the many production vehicles equipped with it,” says Hilko Hakvoort, head of the High Voltage Dr ives product line at Vitesco Technologies. “The use in the Twike 5 shows how diverse the potential applica tio ns of EMR3 can be. With its minimal space requirements, low weight and riding pleasure, it’s tailor-made for this small, lightweight high-performance vehicle.”
Martin Moescheid, managing director and shareholder of Twike GmbH, based in Rosenthal, Germany, undersc ores this. “In addi tion to performance, efficiency was also of central importance to us. The EMR3 has a high degr ee of efficiency in all load ranges, wh ich means that we can achieve very low consumption values. In addition, thi s drive unit is particularly lightweight, extremely robust and easy to modify. The background of existing high-qu ality volume production also made a significant contribution to our decision.”
The Twike – a portmanteau word from Twin and Bike – goes back to students from ETH Zurich, who developed the prototype of this enclosed two-seater recumbent bike in 1986. To this day, the pedals have remained a fea ture of this vehicle type. While the current Twike 3 production model uses this to mechanically support the drive shaft, in the Twike 5, pedal force is used to generate electrical energy. In both cases, this relieves the burden on the battery and increases the range. Above all, however, the pedals are intended to allow sporting activity duri ng riding. With an output of 70 kW and a torque of 1,800 Nm on the drive axle, the Twike 5 will be by far the most powerful model in the brand’s history.
