Those most extreme gas-guzzlers that would rather start a bonfire on a polar icecap than temporarily deactivate its monstrous V12 engine when faced with a red light.Here, we look at the least economical cars you can buy right now, in descending order:Bentley Flying Spur – 19.8mpgThe first of three Bentleys on this list and confirmation that you\u2019ll be seeing nothing above 20mpg here. The Flying Spur\u2019s 6.0-litre W12 engine cares not for your silly global warming.Bentley Mulsanne – 19.3mpgBigger and heavier than the Flying Spur, the \u00a3229,360 Mulsanne uses a 6.75-litre V8 but considering it weighs more than 2.7 tonnes, we won\u2019t be too harsh. One peculiar side point though, the extended wheelbase Mulsanne – which is 50mm longer, 45kg heavier and \u00a346,000 more expensive – uses just as much fuel. Must be that Bentley witchcraft\u2026Aston Martin V12 Vantage – 19.2mpgYou may have spotted the theme now: all the least economical cars are made by uber premium high-end manufacturers, and the types of people that can afford to buy them probably don\u2019t spare a second\u2019s thought for how much fuel it uses. Spoiler alert: the next car isn\u2019t a Dacia…Aston Martin DB9 – 19.0mpgWe\u2019re showing you the Bond Edition DB9 here, limited to just 150 units and created to celebrate the release of the James Bond\u2019s 24th theatrical outing Spectre in 2015. Why? Because Bond reasons, that\u2019s why.Ironically, the DB9 has never appeared in any 007 movies, yet with a six-litre V12 633bhp engine hurtling it to 62mph in 4.1 seconds, we can\u2019t think why.Bentley Continental GT Speed Convertible – 19.0mpgOh god, more Bentleys? \u2018Fraid so but this is the last one, promise. This one only weighs 2.5 tonnes though.Rolls-Royce Phantom extended wheelbase – 19.0mpgThe ultimate in luxury motoring. One of these is probably double what your house is worth. Coincidentally, this stretched-out Phantom – which costs \u00a3378,824 – is actually about as easy to drive as a bungalow.Ferrari GTC4Lusso – 18.8mpgWe had plenty of nice things to say about the GTC4Lusso in a recent feature but it\u2019s hard to be kind about its pocket-crippling fuel economy. Still, nought to 62mph in 3.4 seconds justifies every penny of its \u00a3230k asking price.Ferrari F12 TDF – 18.3mpgThis limited-run Ferrari is sold-out and it\u2019s just as well because it\u2019ll probably kill you before you come close to running out of fuel. Point and laugh as you watch Top Gear\u2019s Chris Harris try to tame this 6.2-litre monster.Maserati GranTurismo S – 18.2mpgIt\u2019s crazy to think that this two-door four-seat grand tourer coupe glugs more petrol than any Ferrari but it actually incorporates elements of Ferrari\u2019s 599 GTB.Vauxhall VXR8 GTS – 18.0mpgThe cheapest car on our list is the second thirstiest, and again, it\u2019s slightly bewildering that a Vauxhall is more expensive to run than an Aston or Bentley. For the price of one extended Rolls-Royce Phantom, you could have six of these.Lamborghini Aventador – 16.4mpgOf course, Britain\u2019s biggest gas-guzzler had to be a Lambo! To be honest, this 6.5-litre V12 750-4 Superveloce Roadster was the first car we thought of when compiling this list and evidently, no car could out-glug it.Hitting 62mph in under three seconds sounds amazing but with a 90-litre fuel tank, you won\u2019t get very far. Even if you achieved the official 16.4mpg, it wouldn\u2019t be able to complete a London to Manchester round trip without at least one fuel stop."},{"@context":"https:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Blog","item":"https:\/\/smart-motoring.com\/blog\/#breadcrumbitem"},{"@type":"ListItem","position":2,"name":"Britain\u2019s least economical cars","item":"https:\/\/smart-motoring.com\/blog\/britains-least-economical-cars\/#breadcrumbitem"}]}]
