Mazda is working on what is in effect a tri-fuel vehicle. A Mazda5 fitted with a rotary engine which can run on hydrogen or petrol and is also linked to an electric motor is front-wheel drive, so becomes the first front-wheel drive, rotary-engined Mazda. “It’s very much in the prototype stage at the moment,” Jeremy Barnes, group manager for product communications at Mazda North American Operations, told reporters at the Detroit Motor Show.

Mazda says rotary engines are well suited to hydrogen because in conventional engines, hydrogen can cause pre-ignition due to their higher operating temperatures. Mazda currently has four dual fuel (hydrogen and petrol) vehicles running in Japan and is launching its 2008 Tribute HEV with a hybrid petrol-electric engine in the USA in the middle of this year.


Mahindra unveiled India's first SUV with the advantage of a hybrid powertrain called Scorpio-HEV (hybrid electric vehicle) at the ongoing New Delhi Auto Expo.

A new generation of Honda's Integrated Motor Assist (IMA) technology helps the Civic achieve an estimated fuel economy rating of 4.7 L/100km (city) and 4.3 L/100km (highway) - improved from the 2005 Civic Hybrid's figures of 4.9 and 4.6 L/100km.

The new Civic brings a roomier interior, more spunk under the hood, and fuel mileage around 40 mpg on the highway.
