You don't have to buy a hybrid to go green – but it sure helps.

Honda Civic Hybrid

The Civic demonstrates the efficiency of Honda’s Integrated Motor Assist (IMA) system: a 1.3-liter engine combined with an electric motor that makes 49 city/51 highway mpg. Although the motor normally supplements the engine, an electric-only mode provides petroleum-free propulsion in certain cruising and low-speed situations. A combined 110 horsepower and 123 lb.-ft. of torque is achieved, mated to a continuously variable transmission. AT-PZEV certification is thanks in part to plastic-resin fuel tanks that produce zero evaporative emissions. An idle-stop feature on the engine shuts the unit off when motionless.
