Powerful. Save. Environmentally sound. The QUANT 48VOLT shows the evolution of the nanoFlowcell® electric drive, away from inherently dangerous high-voltage towards safer low-voltage based drive systems.  48VOLT indicates the presence of flow cell technology in the lower voltage range low range. QUANT 48VOLT is the world's first sports car with an innovative low-voltage drive, which shows exceptionally high performance at extremely low voltage. The 760 hp strong electric rocket with a torque of 2,000 newton metres per wheel  accelerates from zero to 100 km/h in 2.4 seconds. In combination with the QUANT 48VOLT, the nanoFlowcell® 48VOLT drive shows self-confidence. While its performance underlines the fun factor of a electrically powered sports cars, the flow cell electric drive also presents itself here as the lightest, safest, most environmentally compatible and economical powertrain system currently available anywhere for electric vehicles.



Development progress in flow cell technology allows for extreme performance (>560 kW) for the very first time from a low-voltage architecture (up to 48 V). The surface of the flow cell’s membrane structure had been nanotechnically optimised for increased reactive surface, without significantly changing the overall dimension of the nanoFlowcell®. Additionally, the QUANT 48VOLTS has six flow cells working simultaneously to generate more drive power by maximise discharging capacity for bi-ION electrolytes. 

The drive engines are a complete new development. Other than traditional electric motors with copper winding, QUANT’s innovative 45-phase, 140 kW strong low voltage drive motors have a solid stator structure made of light alloy. Motors become lighter, more compact and more economical. Additionally, they provide the electric sports sedan with tremendous acceleration, reaching is electronically limited top speed of 300 km/h speed with playful easiness and without acceleration gaps. Drivable range can be expected to be more than 1,000 kilometres – a plus of 25 percent compared to the QUANT FE with high-voltage drive system.

A unique VCU controls the complex electric powertrain and regulates the drive current. Depending on drive modus and the respective power requirements, the VCU switches on or off three of the six flow cells in the nanoFlowcell® 48VOLT drive system of QUANT 48VOLT.

QUANT 48VOLT not only meets arguments of those who are sceptical a about performance of electric cars, but also those who worry about electrical safety. With the implementation of a low voltage drive system, the QUANT 48VOLT becomes the electrically safest EV on the market today.


Characteristic for QUANT sports coupés prototypes are the details in the overall concept of such pioneering electric sports cars. One special feature of the new QUANT 48VOLT is the control panels made from genuine wood with sensor functions hiding underneath and only light up when the car is starting up.

The new sensorFLOW® technology creates a visual highlight never before seen in this form for car controls. To begin with, all you can see is the clean, smooth surface of the natural ash. Haptic without apparent functionality. Once activating the vehicle electrical system, the controls (in the form of capacitance switches) become clearly visible through the wood.

The wooden veneer is so thin that lightly pressing a finger on the sensorFLOW® technology icons is all it takes to trigger the corresponding function. This innovation forms a fingertip connection between the inimitable feel of real wood, and the purely digital operating system.


Modern display technology at a width of more than 125 centimetres and a height of more than 16 centimetres, informs the driver about all relevant vehicle functions. The single unit front display shows the status of the instrument panels, the head unit with specific EV info and the entertainment system.

Flowing lines front to rear form another strong visual element. The consistently horizontal division of all the instruments creates clarity. Classic “pointers” are replaced by a modern pie-chart look. A torque read-out replaces the classic rev counter, with the torque figures from all four electric motors individually recorded and displayed. The driver can also use the display to follow the vehicle’s overall energy management in real-time.

All instrument functions in the cockpit interact with a smartphone of tablet PC for recording and checking vehicle data or individualizing digital cockpit appearance.
