HONDA has begun a campaign to find the driver who has clocked up the most miles in its pioneering petrol electric IMA vehicles. And the company is prepared to offer a free replacement Civic IMA to the owner of the best presented original model with a recorded mileage of 100,000 or more.

"We want to highlight how much money IMA drivers will have saved in fuel bills and tax - as well as demonstrating how much CO2 has been prevented from entering the atmosphere," said Faye Burton, Environmental Manager from Honda UK.

Since its introduction in 1999 the Insight has consistently been the most fuel efficient mass produced car in the world. Five years on from its launch, it still comfortably beats all competition, returning a staggering 83.1mpg on the EU combined cycle test - with a yet-to-be-surpassed carbon dioxide (CO2) emission figure of just 80g/km.

Over a three year period a company car Insight driver clocking the standard 20,000 miles per annum would have saved nearly £3,400 in fuel and benefit-in-kind tax and over 8 tonnes of CO2, over a standard 1.6 petrol hatch.
