Among the Tokyo-bound brigade will be Suzuki’s Regina concept, which the company says offers a vision of a next-generation global compact car, one displaying excellent fuel efficiency and low emissions through lightness of being and superior aerodynamics.

The Regina weighs just 730 kg, so it’s as light as a minicar, and aided by a clear focus on minimising weight, the company says this funky Suzy has a drag coefficient at least 10% lower than that of current models, all due to uncompromising efforts to heighten aerodynamic performance.

As a result, it offers a fuel economy of at least 32 km per litre (measured in the JC08 test cycle) and CO2 emissions as low as 70 g/km (under the NEDC) using a petrol engine. Of course, there’s no mention of exactly what mill the car uses – more when the 42nd running of the show takes place, one presumes.
