Top Trumps - first launched in Britain 30 years ago - is going green.

A new limited edition version of the iconic school playground game has been produced that includes only eco-friendly vehicles.

It has been developed by climate change charity Marches Energy Agency in association with Winning Moves, the Top Trumps company.

Whereas engine size and horsepower used to be winning features on the key trump cards, now lowest CO2 emissions, fuel efficiency and greatest number of seats are superior.

So, out go the Porsches and the Ferraris and in come hybrids and electric motors.

A pack of the cards will be distributed free to every secondary school in the country.

Fleet managers and travel co-ordinators across Britain will also receive a 20-page Green Driving Guide.

The whole initiative, part funded by the European Union, is supported by Toyota, Honda, Blooming Futures, Organic Power, The GreenBus, and Vectrix.

Kris McGowan, the senior project manager at Marches Energy Agency who helped to develop the new game, said: "Eco Vehicles Top Trumps is a fun and entertaining way to educate youngsters about the new range of climate friendly options available for transport.

"There are also vehicles in there for the 'petrol heads', like the Tesla, that has a top speed of 133mph, or the Killacycle that does 0-60mph in under one second. Both of these are electric."
