From October 2008 the standard equipment of the 45 kW/61 bhp and 52 kW/71 bhp petrol-engined smart fortwo models will include micro hybrid drive (mhd) technology with a user-friendly automatic start-stop system. This reduces the NEDC consumption of the two naturally aspirated engines by an average of 8 percent. In city traffic fuel savings of almost 20 percent are even possible. Furthermore, from the autumn of 2008 the smart fortwo cdi will be equipped with a closed diesel particulate filter that almost completely eradicates particulate emissions. The equipment of the innovative two-seater is being upgraded by an instrument cluster with a new design featuring enhanced indicating instruments and new door net pockets among other things. Two new colours "grey metallic" and "rally red" are a fresh new highlight, as are the optional new sporty six-spoke alloy wheels.
