Swift Plug-in Hybrid is meant for drivers who travel low mileages of around 20 km every day and is designed to be driven primarily on electric power. It is fitted with a compact 660 cc engine and equipped with a generator to charge the lithium-ion battery if capacity level drops. Further recharging when parked is by means of a domestic plug socket. The type of petrol engine used for the Hybrid is similar to that fitted to Suzuki's compact dimension and low tax 'Kei' cars in Japan.
Also on display as part of Suzuki's longer term future is the SX4 FCV (Fuel Cell Vehicle) which combines a General Motors produced high performance fuel cell with a Suzuki developed high pressure hydrogen tank and a light and compact capacitor. The capacitor helps to promote driving performance by recovering energy during braking and using it to reduce fuel cell loading under acceleration. The FCV is currently under test on public roads in Japan.
