2011 Nissan Micra DIG S

The 2011 Geneva Motor Show is turning into a regular environmental fair - with the exception of the Lamborghini Aventador LP700-4 of course - and now Nissan is joining the bunch with a special Micra model. The new Micra DIG S will be powered by a petrol engine, but that engine will only produce 95g/km of CO2. Sales will begin Summer 2011.

The new Micra DIG S is powered by a 1.5 liter four-cylinder Direct Injection Gasoline-Supercharger engine that delivers a total of 98 HP and 142Nm of torque, while emitting only 95g/km for the manual version and 115 g/km for the CVT version. The car can hit a top speed of 112mph when coupled with a manual gearbox. The DIG-S uses the Miller cycle and direct petrol injection to raise the compression ratio to 13 to one for greater combustion efficiency and a supercharger for instant throttle response and added power.

"Ultra low emissions with no compromise when it comes to drivability means the Micra DIG-S sets new standards for the current generation of city cars. No other petrol-powered compact hatchback can beat its overall efficiency... and it is more than a match for an equivalent diesel. We have been able to achieve this ultra low CO2 figure in a cost effective package and without the complication of particulate filters needed to clean up diesel engine emissions and which are not entirely compatible with a car that spends much of its life in the city."
