Drive

Powerful and efficient.

The powerful 55 kW electric motor and the lithium-ion battery with capacity of 17.6 kWh are the central components of the high-performance and efficient drive concept. With torque of 130 Nm immediately available, the smart fortwo electric drive accelerates from 0 to 60 km/h in just 4.8 seconds, from 0 to 100 km/h in 11.5 seconds, and quickly reaches a top speed of 125 km/h.

Depending on factors such as driving style, traffic situation and use of heating, air conditioning and other electrical consumers, a range of up to 145 km can be achieved.

Electric motor.

The magneto-electric motor has a lightweight design and fits compactly in the rear of the vehicle. Unlike a combustion engine, the electric motor consists of a small number of components that barely show any signs of wear, thus keeping maintenance costs to a minimum. There is no need to change the oil or to replace spark plugs, toothed belts or belt pulleys. Other advantages offered by the electric drive are the smooth, even and virtually noiseless power development and the shift-free driving.

Battery.

The lithium-ion battery in the smart fortwo electric drive was developed by Deutsche ACCUmotive, a Daimler AG subsidiary specially set up to develop and produce batteries. This battery offers a number of advantages compared with conventional lithium-ion batteries. For a start, it can be used in a wider range of outside temperatures and it has both a higher cycle strength and a longer service life. Partial charging is also possible at any time – because lithium-ion batteries have no memory effect which means that the range is not reduced. In this way, the smart battery meets all the demands made on an electric car designed for everyday use.

Power consumption.

Driving with 100% electricity is easy not only on the environment[1] , but also on your pocket. This is because the smart fortwo electric drive consumes only 15.1 or 14.3 kWh per 100 km, depending on whether the battery is charged at a household socket or a wallbox.
So now all you need to do is to check the price of electricity per kilowatt hour – and you will find that electric mobility is very cheap indeed.

Recuperation.

In deceleration mode and during braking, the electric motor works as a generator that converts part of the surplus kinetic energy into electrical energy. This then flows back into the battery, ultimately increasing the range.
