The diesel-powered smart fortwo cdi demonstrates how economical and environmentally-friendly a car can be. Now, with its micro hybrid drive (mhd) technology, smart can offer a fuel-efficient solution for its petrol engines, too.

The micro hybrid drive technology in the smart fortwo mhd uses a start/stop function that automatically switches the engine off at traffic lights or in a traffic jam, and back on when things get moving again. The mhd switches the engine off as soon as you brake and fall below a speed of 5 mph. When the time comes to set off again, take your foot off the brake pedal and the engine will start again seamlessly with first gear automatically engaged so that you can continue your journey. This reduces consumption and CO2 emissions. In fact, the smart fortwo mhd's start/stop generator enables a fuel saving of 8%[1] or up to 11% in city traffic[1], all without compromising on performance or comfort.

Combined fuel consumption for fortwo coupé 71bhp mhd of 65.7 mpg / 4.3l/100 km[2], combined CO2 emissions of 103g/km[2]; combined fuel consumption for fortwo cabrio 71bhp mhd of 64.2 mpg / 4.4 l/100 km[2], combined CO2 emissions of 105g/km[2].

[1] The figures stated were determined in accordance with the stipulated measuring method (directive 80/1268/EEC the currently applicable version). The data do not relate to an individual vehicle and do not form part of an offer, but are intended solely for the purpose of comparison between different types of vehicle. The figures stated depend on the tyre dimensions.

[2] Calculation basis: A comparison of the official fuel consumption figures for the smart fortwo coupé 71bhp (52kW) and smart fortwo coupé 71bhp (52kW) mhd showed that the smart fortwo micro hybrid drive coupé consumed approx. 11 % less fuel in the urban cycle and approx. 8 % less in the combined driving cycle. The consumption figures may vary depending on the actual traffic situation and individual driving style.
