Not all newer vehicles are clean vehicles, experts have noted.

According to recent articles, less than 5.7 % of the energy that is burned in fuel to power vehicles is consumed by cars that run on alternate fuel. Models that run on E85/Flex, electricity, gas/electric hybrids, hydrogen fuel cells, natural gas, etc. consist of a yet small amount of vehicles on the road. By 2040, experts believe that alternative fuel vehicles will utilize 13.7 % of all light-duty vehicle fuel.

According to some studies, vehicles considered to be the dirtiest in America usually have the lowest scores in three EPA categories known as Air Pollution Score, Combined Fuel Economy and Greenhouse Gas Score. Experts have decided to come up with a list of the dirtiest vehicles in the country by looking into newer models and their EPA ratings. According to the report, rates regarding air pollution scores are linked to the amount of pollutants that cause smog the vehicle’s tailpipe emissions are releasing into the air. Vehicles were rated in scales from 1 to 10 and according to experts, ten is the best and cleanest vehicle while 1 is the dirtiest.

Details regarding these ratings may be found at the U.S. Department of Energy and U.S. Environmental Protection Agency’s website.
Although the EPA classifications may produce incoherent results if the consumer is looking into models that have either been discontinued or replaced, experts decided to list the dirtiest vehicles available.

Some of the models found in the list include the Bugatti Veyron that gets 10 miles per gallon and has received a 5 out of 10 air pollution rating. The Mercedes-Benz SLS AMG Coupe and the Mercedes-Benz C63 AMG have received 5 out of 10 in air pollution ratings. Both models get about 15 miles per gallon, reports indicate. Experts have also placed the Chevrolet Suburban as one of the dirtiest vehicles available. The Suburban will get 12 miles per gallon and like the previous models and it was rated 5 out of 10 when it comes to air pollution. The Cadillac CTS-V Sedan gets 14 miles per gallon and despite the fact it was rated 2 out of 10 when it comes to greenhouse gas, it was rated 5 out of 10 for air pollution.

Ferrar’s FF model and the Maserati Quattroporte share Cadillac CTS-V’s air pollution and greenhouse gas ratings.

Both Mercedes-Benz S600 and Chevrolet Camaro ZL1 get 14 miles per gallon and rate 5 out of 10 when tested for air pollution.
