America’s dirtiest vehicles

How dirty are the cars on our roads – even though most of the Dodges and Chevrolets aren’t sold here.

Just because a car has low fuel efficiency doesn’t mean it’s the worst polluter on the road. The Chevrolet Suburban and Dodge Challenger are some of the biggest gas-gulpers available, but they don’t cause quite the environmental harm other cars do.

That title is reserved for vehicles that combine their poor gas mileage with high tailpipe and greenhouse gas emissions. Think along the lines of some of the bulkiest cars on the road, like the Jeep Grand Cherokee, Chevrolet Trailblazer and Dodge Dakota.
