Suzuki has announced plans to introduce three concepts at the Tokyo Motor Show. They are all relatively compact and focus on having low emissions.

Suzuki has announced plans to introduce three concepts at the Tokyo Motor Show.

First up, the Regina weighs 730 kg (1,609 lbs) and "embodies Suzuki's vision of a next-generation global compact car." Power comes from an undisclosed engine which enables the concept to return 75.2 mpg US (3.1 L/100km / 90.3 mpg UK) while having CO2 emissions as low as 70 g/km.

Next up, the Q-concept, which seems to mimic Nissan's Pivo concept, is designed to blend motorcycle maneuverability with car-like convenience. The company says the vehicle is "ideal for everyday journeys within a radius of about 10km (6.2 miles)," so it likely uses an electric powertrain.

Lastly, the Swift EV Hybrid can travel 20-30 km (12.4-18.6 miles) on electricity alone. When the battery is depleted, an engine acts as a generator to extend the concept's range.
