Fuel Economy The Great national Delusion.









I have reached the stage of life where “fuel economy” is no longer a technical concept but a personal lifestyle, like yoga, except with more swearing.

Every time I get behind the wheel, I become a one‑man scientific experiment in how far a car can travel on a thimbleful of petrol while the dashboard computer screams, “YOU’RE DOING IT WRONG.”Modern cars claim to help you save fuel by offering “eco‑driving feedback,” which is a polite way of saying the vehicle constantly judges you. My car has a little green leaf icon that lights up when I’m driving sensibly. This sounds wholesome until you realise the leaf goes dark the moment you accelerate even slightly, as if the car is saying, “Well done, Jim, you’ve just murdered a rainforest.”

Manufacturers insist these systems are there to “encourage efficient habits,” but what they actually encourage is rage. You find yourself trying to coax the leaf back on by driving like a Victorian governess guiding a horse-drawn carriage. Meanwhile, the drivers behind you are expressing their own views on fuel economy by attempting to ram you into a hedge.Of course, the real problem is that fuel economy figures are created in laboratory conditions that bear no resemblance to the real world. The official test assumes you will be driving on a perfectly flat road, with no wind, no traffic, no passengers, no luggage, no weather, and no will to live. 

The car is also driven by a professional who weighs approximately the same as a helium balloon. Under these conditions, the vehicle achieves a miraculous 78 miles per gallon.In the real world, you get 34.And that’s only if you’re going downhill.With a tailwind.And the engine switched off.I once tried to improve my fuel economy by following online advice. The first tip was “remove unnecessary weight.” This sounded reasonable until I realised the only unnecessary weight in the car was me, and I needed to be there to drive it. The next suggestion was “avoid harsh acceleration,” which is difficult when you live in Britain, where every junction requires you to accelerate from zero to “oh dear God” in three seconds to avoid being flattened by a bus.Then there was “maintain steady speed.” This is impossible in the UK, where the roads are designed by someone who clearly hates humanity. You can’t maintain a steady speed when every 200 yards there’s a roundabout, a speed bump, a pothole the size of Wales, or a man in a fluorescent jacket digging a hole for reasons known only to him and the council.

I also tried “coasting,” which is when you let the car roll without accelerating. This works brilliantly until you remember you live in a country with hills. Coasting downhill is fine, but coasting uphill is basically a slow-motion re-enactment of the Titanic, except with more grinding noises and fewer violins.Electric cars claim to solve all this by offering “regenerative braking,” which means the car recharges itself every time you slow down. 

This sounds futuristic until you realise it encourages you to brake constantly, which is not ideal when you’re on the motorway and the lorry behind you is close enough to read your dental records.
In the end, the only truly reliable way to improve fuel economy is to drive less. But that’s not practical, because life insists on happening in places that are not your sofa.

So we soldier on, clutching our receipts from the petrol station like war medals, telling ourselves that next time we’ll do better, next time we’ll drive more efficiently, next time the little green leaf will stay on.It won’t.But hope, like fuel, is something we continue to burn through at an alarming rate.
