Fuel Efficient Vehicles and Alternative Fuels Smart Choice Guide:
How to Choose a Vehicle
Green Vehicle Guide assists users in choosing the cleanest and most fuel-efficient vehicle that meets your needs. Green vehicles have high fuel economy, low greenhouse gas emissions, and low criteria pollution emissions. These pollutants cause smog and soot – include oxides of nitrogen, volatile organic compounds (VOCs), carbon monoxide, and particulate matter. Green vehicles can run on low-carbon fuels, such as grid-supplied electricity and sustainable biofuels. Examples include high efficiency hybrids, plug-in hybrids, battery electric vehicles, flex-fueled vehicles that actually run on sustainable biofuels, flex-fuel plug-in hybrids.
In partnership with the West Coast Collaborative (WCC) the Advanced and Alternative Vehicle and Fuel Technologies: User Guide for Medium- and Heavy-Duty Truck Fleets was developed to address needs expressed by industry consumers regarding the availability and performance of vehicle technologies and fuels for reducing diesel emissions and improving fuel economy. The guide includes descriptions of available vehicle and fuel technologies, benefits relative to conventional diesel internal combustion engines (ICEs), lessons learned from real world applications, funding and financial incentives, and tools to help owners, operators, and managers pick the right technology for their business or fleet.
On-Road Vehicles and Engines has links to information about highway vehicles (cars and light trucks, heavy trucks, buses, engines, and motorcycles) including fuel economy, emission standards and regulations, emission recall programs, new vehicle certification and in-use vehicle compliance, inspection and maintenance programs, diesel retrofit programs, evaluating the benefits of inventions designed to reduce emissions, and importing vehicles to the United States.
Vehicles listed on the DOE and EPA sponsored Fuel Economy site have gas mileage estimates and more information for 1984-2010 model year cars. Selecting which vehicle to purchase is the most important fuel economy decision you'll make.
