Have you ever put petrol in a diesel car? If so you’re in good company – the AA reckoned there were 100,000 miss-fillings in 2005.
But now there's an answer, or at least there's an answer if you've got upwards of £53,995 to spend on the new Range Rover TDV8.
Land Rover claims to have come up with the world's first petrol guard. The system is incorporated into the TDV8's filler. In the event of a thinner petrol nozzle being inserted into the aperture, a mechanical shutter activates, preventing petrol from entering the tank. This is because petrol nozzles are thinner and go further into the aperture than diesel nozzles.
Chief programme engineer Paul Walker said: "The new TDV8 engine in the Range Rover is so powerful and refined we feel that there is a danger, more so with this vehicle than with any we have sold in the past, of the driver mistaking the vehicle for a petrol-powered derivative – especially if the driver isn't the vehicle's regular user."
We've yet to try putting petrol in the TDV8, but if you do, let us know.
