Nissan has upgraded its Micra DIG-S compact car with a new supercharged engine and low-emission technologies.
The 1.2-litre, three-cylinder petrol engine on the model has had its output boosted by as much as 23% - from 79bhp to 97bhp.
Fuel efficiency improvements on the Micra DIG-S include a direct fuel injection system, valve timing control with an eco-mode, redesigned pistons and increased compression ratio.
As a result the new car promises a combined fuel economy of 68.9mpg, which puts it in the league of small diesel cars.
Emission improvements, including better exhaust gas recirculation, give the car a maximum CO2 output of 99g/km, which means buyers will not need to pay taxes on it.
Nissan is targeting city users with the new Micra DIG-S, which comes equipped with a stop/start system optimised for heavy traffic conditions and the intelligent alternator control system to recharge the battery when braking.
