Your vehicle's emissions are comprised of both your vehicle's base output and your driving habits combined. While driving habits can make a noticeable difference in both emissions and fuel economy, the vehicle's overall capacity to produce clean emissions is by far the most important consideration. Don't be fooled into thinking you can make a rather large polluting vehicle economical through the use of good driving practices and aftermarket parts. Electric vehicles are the cleanest and meanest form of zero emission transportation you can get today. Hybrids are the next best thing, offering a smart combination of gas-power and electric assistance. The trickiest vehicles to choose between will be your gasoline vehicles which range from good to bad depending on the engine, weight, and powertrain design. A few of your best bets according to GreenerCars.org are the Toyota Prius, Honda Civic Hybrid, Toyota Yaris, Honda Fit, Ford Escape Hybrid, and Hyundai Sonata.
