Hybrid Vehicle Guide

In a "mild" system, the gas engine starts up again when the manual-transmission gear selector is moved into gear, or when the driver's foot moves from the brake to the gas pedal of a model with an automatic transmission. Full hybrids start off on battery power each time, but typically start the gasoline engine within a second or two.


Honda is the only manufacturer that offers manual shift in a hybrid car. Most use a continuously variable transmission (CVT), which is similar to an automatic but operates a bit like a dimmer switch, producing an infinite number of drive ratios.

No Plug Required
Hybrids never need to be plugged in anywhere. Typically, when a hybrid vehicle is cruising, the gasoline engine acts as a generator to recharge the batteries. The charging process is most pronounced when the vehicle is slowing down, making use of what's called regenerative braking.


Because urban stop-and-go driving takes best advantages of the hybrid powertrain, especially with a CVT, mileage estimates from the Environmental Protection Agency (EPA) are typically higher for urban operation.


Dashboards usually include a display screen that can show how the hybrid system is operating. A quick glance reveals whether the vehicle is running on gasoline or electricity (or both), how frugal it's been in recent driving, and other details. Beware, though: some of the displays are almost mesmerizing, and it's hard to keep your eyes off them. Fortunately, you can shut off the screen.


Let's take a look at the hybrid models that are now on sale, and will be arriving soon.

Honda Insight
Honda paved the way for hybrids with its futuristic-looking Insight, a two-passenger front-drive vehicle that debuted in the 2000 model year and remains on sale today. In its Integrated Motor Assist system, the Insight's 1.0-liter, three-cylinder gasoline engine is supplemented by a small electric motor, which kicks in to deliver a boost for quicker acceleration. Aero-profiled for efficiency and fitted with low-rolling-resistance tires, the Insight has a rounded teardrop shape. The battery pack fits behind the seats.


Both a five-speed manual gearbox and a continuously variable transmission (CVT) are available. Current CVT-equipped models earn an EPA fuel-economy rating of 57 mpg in city driving and 56 mpg on the highway. Manual-shift models get an estimate of 60-mpg city and 66-mpg highway. Fun to drive, the Insight performs energetically with manual shift, though the CVT version is tamer. Cargo space is minimal, and ultra-lightweight construction takes its toll on ride comfort.
