Smart Fortwo Electric Drive

Environmental friendliness and contemporary functionality have been defining features of the smart fortwo ever since it was launched more than ten years ago. Since then its innovative concept has combined sustainable, forward-looking technologies with individual urban mobility. With a length of just over two and a half metres the extremely compact vehicle can also park perpendicular to the flow of traffic. In addition, the space-saving and environmentally friendly two-seater currently has the lowest fleet consumption and brings its occupants to their destination comfortably and safely. Its design is fresh, youthful, modern and yet sophisticated and has made it an automotive lifestyle icon which shows that mobility, responsibility to the environment and joie de vivre are compatible with one another. The smart fortwo has established a class of its own.

Electric drives have been part of the smart concept right from the start. The later integration of the components needed for electric drive was planned at a very early stage. For example, there is space for the battery in the underfloor between the axles where the tank is located in other smart models . The electric drive module does not limit the space available in the smart fortwo electric drive in any way; there is just as much interior and luggage compartment space as in a smart fortwo with a combustion engine.

A 30 kW magneto-electric motor is installed at the rear of the new smart fortwo electric drive and reacts immediately and without delay. Powerful torque of 120 Newtonmetres is immediately available. This results in a surprising amount of power when pulling away. The smart fortwo electric drive accelerates from 0 - 60 km/h in 6.5 seconds – just as quickly as a petrol model which it initially leaves behind it. Its maximum speed has been deliberately limited to 100 km/h, a suitable speed for the city. Thanks to the power characteristic of the electric motor, the smart fortwo electric drive needs just one single fixed gear ratio. There is no need for any gear changing – a major advantage in dense city traffic. To reverse, the engine's direction of rotation changes.

The second generation smart fortwo electric drive is powered by a lithium-ion battery from Tesla Motors Inc. with capacity of 14 kWh. It is simple to charge at any fused 220 Volt socket. 
A fully charged battery is sufficient for up to 135 kilometres of driving fun (NEDC). This range is more than enough for city traffic as studies have shown that cars drive an average of 30 - 40 kilometres per day in towns and cities. For this, the vehicle only needs to be charged for three hours. Plugging the car in overnight will fully recharge the battery.
