You’ve always felt a bit of a thrill in the heart-thumping speed and pick up of a powerful V12 or V8, something with 500 or 600+ horsepower that makes the blood course through your veins just a little quicker. But you’ve been at war with your inner environmentalist, who dies a little inside each time a mighty twin turbo V12 is fired up and blasting down the highway. It’s a tale as old as humankind itself is. An angel on one shoulder, and a devil on the other. How do you make peace with this inner conflict?

Many don’t. If you’re a fan of powerful gas-guzzlers, you simply drown out the noise with the roar of muscular engines that will get you where you need to go with quickness while burning obscene amounts of fuel and spewing incomprehensible amounts of pollution behind them.

Let’s take a look at 15 wicked gas burners that definitely aren’t planning for the future, but are nearly impossible to walk away from today.

2016 Mercedes-AMG G65


Fuel economy: 11/13 mpg (city/highway)

Gas currently costs around $5.60 a gallon in Germany, but that didn’t stop Mercedes from building the AMG C65, a boxy abomination of an off-roader, with a 6.0-liter twin turbo V12 cranking out 621 hp and 738 lb-ft of torque. Mercedes also built the ultra-luxurious Maybach line until 2013, but now include this brand only as part of a Mercedes Benz-Maybach line. The 2016 Mercedes Benz-Maybach S 600 could have also been a contender in our top 15 gas hogs, with fuel economy of just 13/20 mpg (city/highway).
