Honda's new Civic Hybrid combines a frugal 1.3-litre petrol engine with back-up battery power to drop CO2 emissions to an ultra-low 109g/km.
There's no need to recharge its batteries they top themselves up by harnessing energy otherwise lost when you brake or coast.
The hybrid uses some parts from the new Civic hatchback but, like the IMA it replaces, it's a four-door saloon.
At £16,300, it's pricier than the hatch but equipment levels are high and the costs will eventually be recouped if you consistently hit the officially recorded 61mpg figure.
Run it as a company car and you'll save 3% off your tax rating for choosing a hybrid, while those travelling in London sidestep the Congestion Charge.
Price: From £16,300
MPG: 61.4
CO2 emissions: 109g/km
