Tokyo motor show 2011 - Suzuki concept cars
Aerodynamic efficiency was a priority, so it features partially covered rear wheels and small, rearview cameras instead of door mirrors. Suzuki claims that the Regina’s drag coefficient is at least 10% lower than that of current models.
This impressive figure is combined with a 730kg kerb weight, which means the Regina is 155kg lighter than Suzuki’s current city car, the Alto. That saving is equivalent to chucking out two people.
According to Suzuki, these improvements should help the Regina average around 90mpg and emit just 70g/km of CO2 when fitted with a small-capacity petrol engine.
Like the Renault Twizy, Suzuki’s Q-concept is a cross between a four-wheeled scooter and a Smart car.
It’s 2.5 metres long, has two seats arranged in a tandem configuration and is powered by a small electric motor. However, the claimed range of about six miles is significantly less than the 62 miles that the Twizy can do.
Even so, Suzuki sees the Q-concept as ideal for city commuters because it’s more manoeuvrable than a car, but safer and more comfortable than a motorcycle.
Other cabin layouts are possible. For example, it could have a single seat for a parent at the front and a two-person child seat behind. Alternatively, it could be configured as a delivery vehicle with a cargo area instead of rear seating.
Suzuki Swift EV Hybrid
It might look like any other version of Suzuki’s Swift supermini, aside from its gaudy green wheels and slightly more intricate headlights and grille, but this concept is actually a hybrid.
According to Suzuki, a small car like the Swift is typically driven for between 12 and 18 miles a day (in Japan), distances that the EV Hybrid can cover on battery power alone.
The EV Hybrid can also extend its electric range because the 658cc petrol engine drives a generator.
When the batteries, under the boot floor, no longer have enough energy to power the car, the presence of the engine mean you can keep driving as long as there’s petrol in the tank. As a result, the EV Hybrid isn’t limited to the short, pre-planned journeys that fully electric cars are.
It takes 90 minutes to recharge from a 200v supply and four hours from a 100v supply. The car can also double as a supply to household electricity.
