Gas Guzzlers: The 15 Worst Offenders

Motor Trend logo Motor Trend 10/17/2014 Kelly Pleskot

We've come a long way since the age of the Hummer. At a growing rate, cars are using lightweight materials and turbocharged engines to significantly increase overall fuel economy. Even some of the most inaccessible brands like Ferrari and Lamborghini are changing the auto industry's mindset toward efficiency by dishing out electric cars. Despite the progress that has been made, there are still plenty of inefficient vehicles on the market today. Take a look at some of the nation's top gas guzzlers.


Bugatti Veyron

Combined MPG: 10

Annual Fuel Cost: $5,500

Considering the Veyron is the world's fastest car, it is natural to assume it would also be the most inefficient. And that assumption would be correct. With it coming in at just 8 mpg in the city, we couldn't think of a more difficult daily commuter. The Bugatti's true home is the racetrack, where its 8.0-liter W-16 engine produces as much as 1,200 horsepower and can hit 60 mph in a mere 2.5 seconds.

Chevrolet Express 2500-3500

Combined MPG: 12-13

Annual Fuel Cost: $3,800-$4,150

We wouldn't expect a large van such as the Chevrolet Express to top any fuel economy records. But according to the EPA, buyers can spend $10,000 more in fuel costs over five years compared to gas costs for the average new vehicle sold today. Perhaps the culprit is the van's large 6.0-liter V-8 engine. Models such as the Ford Transit Connect and Nissan NV200 offer four-cylinder engines and achieve fuel economy numbers that are about double those of the Express.

Lamborghini Aventador Roadster

Combined MPG: 12

Annual Fuel Cost: $4,600

At first glance, the Aventador's carbon-fiber frame and aluminum body parts give it the semblance of efficiency. But there is no getting around the supercar's massive V-12 engine, which produces about 700 horsepower. Needless to say, buyers can expect to pay a pretty penny at the pump with this model.

Bentley Mulsanne

Combined MPG: 13

Annual Fuel Cost: $4,250

It's no wonder why Bentley's flagship luxury sedan is so inefficient. The Mulsanne tips the scale with a curb weight of 5,919 pounds, which makes it more than 1,000 pounds heavier than a Hummer H3. And while the Bentley's powerful 505-hp V-8 engine makes the model surprisingly fast, it certainly doesn't help in terms of fuel economy. At a price of more than $303,000, however, most buyers probably won't sweat paying a little extra money for gas.

Ferrari FF

Combined MPG: 13

Annual Fuel Cost: $4,250

It may be the world's coolest station wagon, but the Ferrari FF is also one of the most inefficient cars on the market. Its 4,145-pound curb weight puts it at a disadvantage in terms of fuel economy compared to other models. The FF is available with stop-start technology that turns off the engine at stoplights to conserve fuel, but this new feature doesn't change the car's 13 mpg combined rating. Despite its poor fuel economy, buyers will continue to admire this grand tourer's beauty and interior craftsmanship.

Chevy Camaro

Combined MPG: 14

Annual Fuel Cost: $3,950

It is an American classic, but the Camaro falls behind the curve in terms of fuel economy. When equipped with a 6.2-liter supercharged V-8 and paired with an automatic transmission, the Camaro only manages to score 14 mpg in city and highway driving mpg combined. The manual-equipped Camaro with this engine performs only slightly better. Lackluster fuel economy isn't a surprise in a muscle car, but competitors such as the Dodge Challenger and Ford Mustang have actually made significant fuel-efficiency improvements for the 2015 model year.

Nissan Armada 4WD

Combined MPG: 14

Annual Fuel Cost: $3,550

One of the few remaining body-on-frame SUVs on the market today is the Nissan Armada. It hasn't seen a full redesign in 10 years, which means it continues on with a hefty V-8 engine instead of the more fuel-efficient V-6 setup used on today's three-row crossovers. That said, it provides plenty of power to pass other large SUVs on the road. It can also tow a massive 9,000 pounds when paired with four-wheel drive.

Toyota Sequoia 4WD

Combined MPG: 14

Annual Fuel Cost: $3,550

Many formerly faithful Toyota buyers have abandoned the Sequoia in favor of sensible crossovers such as the seven-row Highlander. But while the Sequoia soldiers on with a V-8 engine that provides uninspiring fuel economy, it does offer advanced technology and surprisingly quiet ride .

Cadillac CTS-V Sedan

Combined MPG: 14

Annual Fuel Cost: $3,950

Despite its subtle appearance, this model is actually one of the most powerful sedans on the market. Its supercharged V-8 engine delivers 556 horsepower and allows this car to compete with the best of the best on the road and the track. The model also comes in a wagon version, although it is equally as inefficient.

Lexus LX 570

Combined MPG: 14

Annual Fuel Cost: $3,950

The Lexus LX isn't your typical luxury family-hauler. Equipped with a large 5.7-liter V-8 engine, the model pumps out 383 horsepower, which is plenty of motivation to help it fly past similar SUVs on the road. Not only is it an off-road king, but it also acts as a comfortable nest for eight passengers thanks to a rear-seat DVD entertainment system, four-zone climate control, and heated middle row seats. Unfortunately, something has got to give, and in this case, it's fuel economy.

Mercedes-Benz G550 4Matic

City/Hwy MPG: 13/18

Combined MPG: 15

Annual Fuel Cost: $3,650

It may not be ideal for city driving, but the Mercedes-Benz G-Class SUV makes a great off-road vehicle. Scaling 45-degree inclines is no problem thanks to the unique technology packed into this military-inspired vehicle. Its four-wheel Electronic Traction System and three sequentially lockable differentials help prove its credentials off the beaten path.

Aston Martin DB9

City/Hwy MPG: 13/19

Combined MPG: 15

Annual Fuel Cost: $3,650

The DB9 makes extensive use of aluminum and magnesium alloy to reduce weight. While the DB9 is more efficient than its DB7 predecessor, Aston Martin's grand tourer still ranks near the bottom in terms of fuel economy. The car is equipped with a 5.9-liter V-12 engine powering the rear wheels and delivering a whopping 510 horsepower.

BMW 760Li

Combined MPG: 15

Annual Fuel Cost: $3,650

To say there is a large variation among the different models in the BMW 7 Series would be an understatement. The base model offers a relatively efficient inline-six cylinder, but stepping up to the top-of-the-line 760Li brings power -- and inefficiency -- to another level. This range-topping model comes with a 6.0-liter V-12 that produces 535 horsepower. As expected, fuel economy takes a huge plunge.

Jeep Grand Cherokee SRT8

Combined MPG: 15

Annual Fuel Cost: $3,650

Opting for the most powerful engine available on the Grand Cherokee will end up costing you at the pump. Compared to the base Grand Cherokee, the SRT8 comes with a 5 mpg fuel economy penalty thanks to its powerful 6.4-liter eight-cylinder engine. The SRT8 version isn't meant for everyone, but those who have gasoline in their veins will trying the Track mode, which showcases the SUV's full capabilities.

BMW M6 Gran Coupe

Combined MPG: 16

Annual Fuel Cost: $3,450

BMW enthusiasts know that any model with an "M" in front of its name signifies it is one of the brand's top-performing vehicles. Among this group, the M6 is tied as the most powerful "M" in the entire BMW lineup. Considering this achievement, we wouldn't expect this 560-hp car to win any fuel economy awards. But at least its fuel economy isn't as low as many other cars with similar power.
