Alas, for Earth-firsters the Prius and hybrid Honda Insight represent irrefutable proof that cars can be practical, affordable, and stingy. We will not attempt to wrestle with that logic here, only some of the facts behind it. Over 900 miles of mostly typical daily commuting, our Prius motored an average of 35 miles and 844 feet on every gallon of gas. That's a zero-percent improvement over the Japanese home-market version we tested in February 1999 and 20 percent below the EPA's official city rating.
A Nissan Sentra GXE tested last June as part of a 13-car comparison of entry-level sedans turned in 28 mpg. Toyota's own five-speed Echo pulled a lofty 33-mpg on the same drive while offering nearly identical interior space, a 0-to-60-mph time 4.2 seconds quicker, and an as-tested price $6591 lower. And both do so without the motive aid and expense of an electric motor, a generator, a very nifty continuously variable planetary gear transmission, and four computers to run this sausage factory.
Toyota said it was a function of the cold weather...
The Honda Insight gets better mileage, but is much smaller and only a 2 seater.
I worry about the cost of replacing the Ni:MH batteries and none of the reviews I've read talk about it...
Good luck.
Cheers,
Scott.
