If all family vehicles in the United States were lined up bumper to bumper- they would reach from the Earth to the moon-and back.

Gasoline
 
Gasoline – While all California cars have advanced emission control systems, many new gasoline vehicles are designed to produce extremely lower levels of emissions. These vehicles have a smog score of 9 on a scale of 1-10 (10 being the cleanest). These gasoline vehicles have a 15 year/150,000 mile warranty and zero evaporative emissions.

Automakers are continually finding new technologies that improve their vehicles. Tremendous benefits have resulted alone by industry's ability to simplify, refine, and reduce the costs of their emission control systems. The cleanest gasoline vehicles are primarily four cylinder engines, however there are some five and six cylinder models available. Many of these cars utilize various combinations of multiple catalysts, several oxygen sensors, exhaust gas recirculation, and an air pump.

Environmental Benefits
With over 500,000 of these vehicles on California’s roads with more to come, gasoline vehicles with smog scores of 9 have an immediate air quality benefit because they are offered in popular models at affordable prices. In addition, the extended warranty provides you with the added security that your vehicle will be maintained for a longer period of time.

Perks and Conveniences
Nothing new here - just a much cleaner version of the conventional internal combustion engine vehicle. In many instances a car buyer may pay only $100 more for a cleaner vehicle model that comes with a better warranty. It is even possible to be driving a clean car and not even know it!

Facts:
  • Gasoline cars with a smog score of 9 have such tight pollution controls, and the burning of fuel is so complete, that in very smoggy urban areas, exhaust out of the tailpipe can actually be cleaner than the air outside.
  • The cleanest gasoline cars sometimes have even lower emissions than hybrid or alternative fuel vehicles
