smart set to roll out a full complement of Alternative Drive Systems

The quick response of the cdi engine is first and foremost thanks to the compact yet extremely effective turbocharger that is housed in the exhaust manifold. Its compressor wheel has a diameter of just 33 millimetres, yet it rotates at up to 280,000 rpm and thus builds up maximum charge pressure of approximately 1200 millibars. This gives the three-cylinder engine more air to "breathe" and enables it to develop impressive torque, even at low revs: 85 Newton metres are available even from 1500 rpm – more than three quarters of the maximum torque.

This torque curve plays an important part in the fun behind the wheel that drivers experience with every kilometre driven in a smart fortwo cdi. The new smart fortwo cdi accelerates from zero to 100 km/h in 19.8 seconds and reaches a top speed of 135 km/h. It therefore offers a combination of agility, economy and environmental compatibility that is unique in this class.
