The greenest convertible in the UK revealed

This time it was the turn of the Green Apple Awards, a series of titles awarded by the Midland Group of Motoring Writers, to find the best green cars in the UK.

The Fiat 500C was named the best green car in the coupe and cabriolet category thanks to the introduction of a petrol engine which is so green, owners do not have to pay road tax or the London congestion charge.

The engine, named TwinAir, even won the International Engine of the Year award this year because it is the only two-cylinder engine currently on sale in the UK.

The Fiat 500C TwinAir returns fuel economy of 68mpg on the combined cycle but it was not just running costs which inspired the judges to choose the retro-styled city car.

“We were looking for cars that are not just green on paper, but are green in the real world too, and are also fun to drive,” says Ian Donaldson, of the Midland Group of Motoring Writers. “The Fiat 500C TwinAir totally encapsulates those thoughts and was a worthy winner.”

The soft-top, three-door Fiat 500C is based on the Fiat 500, the hard-top version of the car launched in 2005.

The Fiat 500 is a name from the Italian car maker’s past and the styling is a modern take on the small 1970s car of the same name.

The Fiat 500C is instantly recognisable on the road, not least because it is available in a number of special editions such as the eye-catching Fiat 500C Pink or the stylish Fiat 500C by Gucci.

Prices for the standard Fiat 500C start from £12,900 but petrol TwinAir versions start from £14,300.

The Fiat 500C and the hard-top Fiat 500 are both available now in Fiat dealerships across the UK.
