As automakers begin warming up to the 2011 Tokyo Motor Show, we’re getting our first intel on the new models that will make their way to the Makuhari Messe convention center in Chiba City, Japan at the end of the month.

Today, Suzuki released initial details and photos of a new concept model for a small city car placed under the Swift.

The Japanese carmaker says that the Regina represents the firm’ vision of “a next-generation global compact car with excellent fuel efficiency and low emissions thanks to lightness and superior aerodynamics”.

According to Suzuki, it tips the scales at just 730kg (1,609 pounds) and has a drag coefficient at least 10% lower than that of current models in the category.

While the concept doesn’t feature a powertrain, the Japanese company says that with a conventional petrol engine, the Regina could return a fuel economy of at least 32km/lt in the JC08 test cycle (72.3mpg US and 3.1lt/100km) and CO2 emissions as low as 70g/km (measured in the New European Driving Cycle).

The Regina measures 3,550mm long, 1,630mm wide and1,430mm tall, while riding on 2,425mm wheelbase. It can seat four passengers in its interior, which features a rather minimalistic styling highlighted by all sorts of shades of green.
