The ultra-low-slung Ryuga features a 2.5-litre flex-fuel engine that can use either gasoline or E85, a blend of 85 per cent ethanol and 15 per cent gasoline. It has a six-speed automatic drive train and headlights that use advanced LED and fluorescent tube technology.

Each side has a large, gull-winged door that allows access to both the front and rear seats. The Ryuga, which is Japanese for ``gracious flow,'' resembles a two-seater on the outside but actually seats four.

There are no immediate plans to release the Ryuga, although Mazda plans to incorporate many of its advanced features in other vehicles, said Laurens van den Acker, general manager of the company's design division.
