A list of the top ten fuel-guzzling cars.

Looking for a green, economical vehicle? Best not opt for any of these cars then!

Currently the fashion is to espouse the benefits of cars which are energy efficient and economically friendly, however there is still room in the market place for cars that consume a large amount of fuel.

Fans of cars will love these speed machines regardless of the how environmentally unfriendly the car’s emissions are.

Here for the benefit of petrolheads everywhere is the top ten least economical cars which can be purchased as a guilty pleasure.

Zooming into 10th place is the Ferrari 599 GTB Fiorano which is priced at a cool £212,016 and comes with a six litre V12 engine. This Ferrari may have been designed with many specifics in mind but economical fuel consumption was not one of them. All of this results in the car averaging 15.8 miles per gallon.

One of the reasons for the poor miles-to-gallon ratio is the speed that this model can reach. The car can travel up to 330 kilometres an hour and can reach 100 kilometres per hour from a standing start in 3.7 seconds.

Coming in at ninth place is the Germanic Maybach 57 5.5 V12 which is a favourite of movie stars such as Samuel L. Jackson. This luxury sedan model has 550 horsepower and goes from 0-100 kilometres per hour in 5.2 seconds. The top speed of the car is a relatively modest 250 kilometres per hour with the fuel consumption figure working out at 15.9 miles per gallon.

Unlike many luxury cars, the Maybach can blend in with its surroundings meaning that it is often a favourite of high-flying businessmen who use their cars to attend meetings and other business functions.

In eighth place and with a price tag of £150,900 is the Bentley Flying Spur Speed. The firm have always been known for its quality and this vehicle is no different, although its consumption rate is 16.6 miles per gallon. Bentley’s four door car can go from 0-60 miles per hour in just 4.5 seconds and has a top speed of exactly 200 miles per hour.

This particular Speed follows on from a long line of Speed models which were originally produced in 1923 under the name of the Continental Flying Speed Spur. As times progressed so did the cars. This particular incarnation of the Spur has 600 brake horse power and a 12 cylinder engine. This car is the first of three appearances in the top ten for Bentley.

Bentley’s next model comes in seventh place with the arrival of the Mulsanne. The car costs £200,000 and features a V8 engine which gives the car the power and elegance for which Bentley’s models are renowned for. With a consumption rate of only 16.7 miles per gallon, the car does little for energy efficiency.

The lack of energy efficiency has a lot to do with the size of the car’s engine which is a twin-turbo V8. The car does have the capacity to drive with four of the cylinders turned off. The car is designed, built and manufactured in Crewe and can be ordered in a range of colours.

At a cost of £135,760, Bentley’s final offering in this top ten list is the sixth placed Continental GT, which was at one time the fastest four-seated car in the world. The car’s consumption rate is a slightly more respectable 17.1 miles per gallon when compared to its fellow Bentleys and can go from 0-100 kilometres per hour in 4.8 seconds.

The Continental GT can reach a maximum speed of 198 miles per hour thanks to its W12 piston engine, a name deriving from its 12 cylinder motor which bears a likeness to the letter W. Bentley’s 2011 Continental GT model has 567 brake horse power and compared to its predecessors has been made substantially lighter thanks to the material used.

In to the top five comes another famous British name, Aston Martin. Their DB9 two door sports coupé is available for £125,050 and its combined consumption figure is 17.2 miles per gallon. Like other cars which are listed in this top ten, the DB9 is powered by a V12 six litre engine and has an array of different settings fitted around its interior.

Gadgets which would befit a James Bond car include cruise control, heated front seats, a trip computer and rear parking sensors. The vehicle also comes with optional extras such as a wide range of wheels and alloys as well as a tracking device.

Maserati’s GranTurismo S storms into fourth place thanks to its rather low efficiency rate of 17.2 miles per gallon. The car is actually comparatively cheap when compared to the rest of the vehicles on this list, costing £92,360. For this price a motorist receives a car whose top speed is 295 kilometres per hour and can go from 0-100 kilometres per hour in five seconds.

It was at the 2007 Geneva International Motor Show that Maserati unveiled their original GranTurismo, with the GranTurismo S designed and displayed at Geneva’s Motor Show a year later. The car was built as a ’2+2′ coupé car and is found largely on European markets after the company withdrew it from North America in 2009.

Aston Martin makes its second appearance in the top ten, powering in at number three. The company’s V12 Vantage costs £135,000 and consumes fuel at a rate of 17.3 miles per gallon. The car’s V12 six-litre engine produces 510 brake horse power and has a top speed of 190 miles per hour. The V12 Vantage can race from 0-60 miles per hour in 4.2 seconds.

The Vantage has been continually honed to perfection to ensure it offers the motorist the best possible drive of their life. For a car which is built so close to the ground, the space afforded to the driver and passenger is substantial in relation to the car’s size.

In second place is the second Aston Martin model to make the list. The DBS, James Bond’s favoured choice of car in Casino Royale, is just beaten to the title of least economical cars to buy. This then is one of the rare instances when Bond doesn’t claim the top prize.

Although it tops out at 191 miles per hour, the high performance Aston Martin DBS is less economical with its fuel consumption, with the car only able to do 17.3 miles per gallon. Priced at £175,891 the car is easy to handle as would be expected of an Aston Martin and comes with a 1,000 watt sound system which has 13 speakers throughout the car’s interior.

Rolls-Royce’s Phantom extended wheelbase is not only an upgrade from the Phantom but also top of the least economical cars to buy. This luxury motor has a fuel economy rate of just 17.9 miles per gallon. At a price of £366,700, the motor vehicle is £51,500 more than the original Phantom model.

Traditionally seen in black, the Phantom extended wheelbase has a walnut and leather interior which has impressed even the most ardent car critics. The car’s frame is constructed from aluminium which is both strong and supple. Not only does the car make for comfortable driving but it also has enough room for the passengers sitting in the back to stretch out in the vast space provided.
