The Sports Car That Runs On Olive Oil

Just as it once did for Mars bars, cooking oil is primed to revolutionise the eco-conscience driving world, too.

Not that you would risk dropping anything deep-friend onto the plush interior of the Trident Iceni. Not only slick, its British makers believe it's the fastest and most efficient diesel sports car on the planet and capable of driving for 2,000 miles on a single tank of pure biodiesel (cooking oil, for short).

Yes, the sleek model you see before your eyes can happily thunder along on rapeseed, linseed palm, soya bean oil, soya bean oil, kerosene and paraffin, with its 6.6ltr Turbo Diesel V8 engine helping it to hurtle from 0-60mph in 3.7 seconds before hitting a top speed of 190mph.

The engine’s eco-credentials are even matched by a patented torque system which gives the lightweight roadster 20 per cent greater fuel efficiency than rival models in its class. And then there's the fuel cost...

Then again, because the striking convertible will set you back a hefty £96,000, not allowing for modifications, we'd understand if you wanted to stick to Unleaded for now.
