Its futuristic Ionis concept car is powered by a fuel cell and features sophisticated drive-by-wire control systems in a sleek, futuristic body.

Ionis converts hydrogen into electricity to drive this compact but spacious commuter vehicle while emitting nothing but water vapour.

Although not intended for production, Ionis gives a glimpse of where Suzuki might soon be heading with eco-friendly production vehicles.

Its brakes, throttle and steering all feature drive-by-wire technology which allows the controls to be positioned for maximum interior space efficiency.

Combined with the space-saving, under-floor fuel cell installation, this allows Ionis to seat four adults in unusual comfort for such a small car.

Four large sliding doors make for easy access to a cabin that is as luxurious as it is modern, with dark brown leather seats, wooden floors, ebony and metal trims and LED lighting.

Clever technology is also applied to an in-car entertainment system that allows passengers to download music via wireless Internet access and to watch satellite TV.
