Top 5 Gas Guzzling Cars In The World

These cars burn through gas at a staggering rate.

In these changing times, automakers can't just be obsessed with horsepower and 0-60 mph times. Fuel economy also has to be a top priority as stricter emissions regulations force automakers to build smaller engines that use up less gas. There are still a few automakers that continue to build gas guzzling cars that we love. If we had hundreds of thousands or even millions of dollars to spend on a car, we would put fuel economy on the bottom of our priorities list. That is why we made a list of the top five least fuel efficient cars in the world. We love these cars even though they are gas guzzlers.

The Bugatti Chiron is among the fastest cars in the world thanks to its 8.0-liter quad-turbocharged W16 engine. This engine is a masterpiece that develops 1,479 hp and 1,180 lb-ft of torque. Unfortunately, this massive engine drinks fuel at an alarming rate. The ratings for the Chiron are 9 mpg in the city and 14 mpg on the highway, with a combined rating of just 11 mpg. If we were willing to spend the roughly $2.7 million required to purchase a Chiron, fuel economy would be the least of our worries. The average Chiron owner has 42 cars, a jet, a yacht and three helicopters, so we are sure that they won't care about the car's abysmal economy.

Aston Martin has recently started to downsize with a and AMG-derived 4.0-liter twin-turbo V8. These new engines will improve on fuel efficiency, but Aston Martin still sells its old naturally aspirated 6.0-liter V12 in the V12 Vantage S. We love this car for its unique seven-speed dogleg manual transmission. However, even if you are frugal with the throttle and the gear shifts, this car will only get around 12 mpg in the city and 18 mpg on the highway. If we were driving this car, we'd constantly drop down gears to hear that glorious V12 engine. Hitting the EPA figures in this awesome sports car would not be easy.

Three of the five cars on this list are powered by V12 engines. The V12 may not be long for this world as we start to see it get replaced with smaller V8 and V6 engines in new supercars. Lamborghini is one of the companies that has pledged to stick to the old ways of building a supercar, however. The Aventador has a 6.5-liter V12 that only gets 11 mpg city and 18 mpg highway. We know that a , that could increase the V12's displacement to 7.0 liters and add a hybrid drivetrain. A hybrid flagship would have more power and get better fuel economy, but it would still be a heavy drinker.

In this spot we have actually included a tie between two V12-powered Ferrari models. The has a 6.5-liter V12 engine with 789 hp. It may be extremely powerful, but this car only gets 12 mpg city and 16 mpg highway. The Ferrari GTC4Lusso has a smaller 6.2-liter V12 with 680 hp, although it sends power to all four wheels. This car actually does a bit worse in the city, with 12 mpg and slightly better on the highway with 17 mpg. Both cars average out to 13 mpg combined, which leaves them tied on our list. If fuel economy is a concern, then the GTC4 Lusso comes with a V8 that gets 15 mpg city and 21 mpg highway.

The final car on our list is the only V8-powered car. The Bentley Mulsanne has been on the market since 2010 and is powered by a massive 6.75-liter twin-turbo V8. This engine is hand-made and takes around 30 hours to build. The blueprint for this engine, but has been updated throughout its life. The most powerful version of this engine produces 530 hp and 812 lb-ft of torque. The huge engine drinks fuel at a rate of 11 mpg city and 17 mpg highway. We aren't sure what replacement car Bentley has in store, but we will surely miss this legendary engine.
