Suzuki will introduce a new 48-volt self-charging hybrid powertrain early next year, which will be offered in the Swift Sport, Vitara and SX4 S-Cross models.
The Japanese automaker claims that their new hybrid powertrain will offer up to 20 percent lower CO2 emissions, more torque and a 15 percent improved fuel economy in the WLTP combined cycle.
The new 48-volt hybrid powertrain will directly replace the current 1.4-liter Boosterjet engine offering more power as well, although the company didn’t share any numbers at this point.
The newly developed powertrain is very lightweight in its design, with the company claiming a weight penalty of less than 15 kg. It consists of a 48-volt lithium-ion battery, an integrated starter generator (ISG) and a 48V-12V converter. The system will be attached to the new K14D Boosterjet engine, an improved version of the outgoing unit.
The ISG is belt-driven and will assist the petrol engine with extra torque from low down, offering 173 lb-ft (235 Nm) from 2,000 rpm. The battery, together with the converter unit, will be located under the front seats for better weight distribution. The upcoming 48V self-charging hybrid system will also be able to use electric power alone at city speeds below 10 mph (16 km/h) to further improve fuel consumption.
Suzuki will announce all the details and specifications of the new 48-Volt hybrid versions of the Swift Sport, Vitara and S-Cross in advance of their launch in Europe, which is planned for March 2020.
