Honda Insight

The Honda Insight is a 2-seat hatchback hybrid automobile manufactured by Honda. It was the first mass-produced hybrid automobile sold in the United States, introduced in 1999 (in Japan, however, the first generation of the Toyota Prius was launched in 1997). According to the EPA, the 5-speed manual transmission variant of the Insight is the most fuel-efficient mass-produced automobile sold in the United States. The Insight is also one of the cleanest: the CARB rated the 5-speed variant ULEV and the CVT variant SULEV. This trade off is due to the 5-speed's lean-burn ability which increases efficiency at the expense of slightly higher NOx emissions.

Developed from the original J-VX design study, it was introduced for the 1999 model year. Honda has announced that production of the Insight will end in September 2006. A new hybrid model, a car smaller and less expensive than the Civic is slated for release in 2009.

The Insight pairs a three-cylinder gasoline engine with a brushless electric motor located on the crankshaft. Behind the driver's and the passenger's seats there is a set of 144 V NiMH batteries. Under heavy acceleration, the electric motor provides additional power while during deceleration, the motor acts as a generator and recharges the batteries using a process called regenerative braking. A computer control module regulates how much power comes from the internal combustion engine and electric motor, to find the optimal combination of power or effeciency from the driver inputs. The current battery charge is shown on the dashboard, as is the instantaneous fuel efficiency and current state of the electric motor, whether it is assisting the engine or charging the batteries.

While the emphasis has been clearly placed on economy, Honda engineers have still managed to make the Insight pleasant to drive. Many new car reviewers have glossed over the lively steering and precise 'snap and click' gear lever offered in the 5-speed manual trim. The narrow low-rolling-resistance P165/65 R14 78S tires aid toward meeting the economy objective, while also exhibiting excellent ride quality characteristics.
