Natural-Gas and Hybrid-Electric Cars Top Green List

Honda's natural-gas-powered Civic GX is the greenest vehicle of model year 2004, according to the American Council for an Energy Efficient Economy (ACEEE), followed closely by the three hybrid-electric models: the Honda Insight, the Toyota Prius, and the Honda Civic Hybrid. The ACEEE released its latest environmental scorings of cars and trucks on February 10th, ranking all U.S. vehicles based on their tailpipe emissions, fuel consumption, and emissions of greenhouse gases. See the ACEEE press release and the online version of the ACEEE Green Book.

While a number of automakers are preparing to release hybrid-electric vehicles, Mazda Motor Corporation is the latest to unveil a hybrid electric concept vehicle. Mazda's Ibuki concept vehicle, which the company describes as "one future approach for a future MX-5 Miata model," is a two-seat sports car that combines a 1.6-liter, four cylinder engine with an integrated electric motor. The motor provides an assist while accelerating and also enables the engine to automatically shut off when the car is stopped. See the Mazda press release.

The Mazda Ibuki made its North American debut at the 2004 Chicago Auto Show, which ended on February 15th. To see more images of the vehicle, see the Chicago Auto Show Web site.
