Top 10 Worst Vehicles for the Environment

3. Bentley Mulsanne

The Bentley Mulsanne will set you back over $300,000. The turbocharged 6.8-liter V8 makes 505 hp and 752 lb-ft of torque. It manages just 11 mpg in the city. Truthfully though, the people who buy cars like the Bentley Mulsanne probably don’t care about what GreenerCars.org says about the environmentally friendliness of any of its cars.
