There are two hybrids now commercially available: The
Honda Insight
and the Toyota Prius. Again,
these are not true electric cars,
but do offer decent gas milage and exceptionally clean exhaust.
When extra power is needed for
acceleration or hill-climbing, an electric motor operates to supplement the
gas engine. A small pack of NiMH batteries is recharged by regenerative
braking and/or from the gas engine acting as a generator. Some differences
between the two cars incldue:
The Prius is an SULEV; The Insight is only an ULEV*.
The Prius can travel short distances as a pure EV (gas engine off);
The Insight can not move without the gas engine running.
The Prius seats 5; The Insight seats 2.
The Prius has a steel frame with 4 doors, the Insight has an aluminum frame with 2 doors.
The Prius has a larger 1.5 liter gasoline engine;
The Insight has a 3-cylinder 1.0 liter gasoline engine.
The Prius gets a modest 50 mpg or so; The Insight can break 70 mpg.
The Prius comes with a CVT [Continuously Variable Transmission]
automatic transmission; The Insight presently comes
with a 5-speed overdrive manual transmission,
although a CVT option is expected next year.
The Prius is a more practical, family oriented car; The
Insight is more sporty, with lots of "techie" readouts and displays on the dashboard.
Both sell for nearly the same price, around US$20,000.
Which is "better" is a matter of personal taste. If you need
to travel long distances on a regular basis, either would
be a good choice. For shorter distances, a true EV is still the ideal choice. Remember that a
genuine electric car can be filled up by plugging into an electric outlet.
This electricity can be from the grid, or from a local source such
as solar, wind, or micro-hydro. No matter what the license plate says or what it is
parked in front of, you can't fill up either of these hybrids with renewable energy!
