"It looks like some kind of deformed fish," said Autocar's picture editor Ben when I showed him a picture of the new Toyota FT-Bh shortly after the dust sheet was pulled off the new car at the Geneva motor show today.

Hmm, one man's boeuf is clearly another man's poisson, because I was smitten by the detailed, intricate lines of Toyota's new eco-concept and intrigued by the technology that underpins the machine.

Like any self-respecting car manufacturer, Toyota is preparing to mount a major 'green' offensive over the coming years, with wide-reaching plans to slash CO2 emissions, and introduce a range of fuel cell, plug-in and full hybrid production cars.

"One year ago I challenged our engineers and designers to come up with a vehicle that was totally designed around fuel efficiency," explained Toyota Europe boss Dider Leroy. "The FT-Bh is the result."

The name stands for "Future Toyota, B-segment hybrid‚" and is the firm's vision of the kind of vehicle we might see in the car market's most hotly constested segment in the future.

The front-drive car is powered by Toyota's Hybrid System with a one-litre two-cylinder petrol engine. The FT-Bh seats four, is less than 4000mm long and weighs just 786kgs - 33 per cent less than a Yaris. The shape, those distinctive wheel covers and some new low-drag Michelin tyres mean the FT-Bh has a drag coefficient of just 0.235Cd.
