From 15kW to +50kW output power

PRODUCT DESCRIPTION

“Integrated Electric Transmission” (IET™) is an extremely compact, high performance mechatronic propulsion unit that emulates the feeling and performance of a traditional internal combustion engine.

A specially developed electric motor, clutch and gear shift, and software enables electric vehicles to accelerate hard from the line up to a high top speed, something that is just not possible to achieve with a single-ratio electric vehicle.

IET™ technology is the solution that takes electric power trains to the next level, making it equal in autonomy, feeling and performance to traditional combustion engines.

Competitive Advantages

  • High power with less dimensions and weight;
  • High acceleration at low gears / high speed at high gears;
  • Feeling is similar to thermal engine;
  • Less power consumption from the battery packs;
  • High efficiency regenerative brake.
