Suzuki Vitara, Swift Sport, S-Cross Get 48V Self-Charging Hybrid System

Suzuki Vitara Hybrid

Japanese automaker, Suzuki has introduced a new 48V self-charging hybrid system in its globally popular models. The new hybrid system will come in early 2020, around March. The new 48V self-charging hybrid system will include the launch of the new K14D Boosterjet petrol engine.

The new Hybrid powertrain will be offered on the Swift Sport, Vitara and S-Cross models. It is claimed to offer up to 20 per cent lower CO2 emissions, a greater level of torque and 15 per cent improved fuel efficiency. These models will directly replace the current 1.4-litre Boosterjet derivatives with manual transmission.

Similar to the 12V Hybrid SHVS system, the newly developed 48V hybrid powertrain will remain lightweight in design and the components add less than 15kg to the overall weight of the vehicle. The new system comprises of a 48V lithium-ion battery, Integrated Started Generator and 48V-12V (DC/DC) convertor to power components requiring lower voltage including lights, audio and air conditioning. The ISG acts as both a generator and starter motor, is belt driven and assists the petrol engine during vehicle take off for a higher level of torque with 235Nm available from 2,000rpm.

The lithium-ion battery stores electrical energy recovered from deceleration and braking and incorporates an idle stop function operated via the Integrated Starter Generator (ISG). The battery is placed under the front seats. The new 48V Hybrid System also gets electric motor idling function when the clutch is disengaged and the engine speed is approximately 1,000rpm. This feature replaces fuel injection with power from the electric motor to then control and maintain idling at vehicle speeds below 10mph (16kmph) and when stationary.

This function therefore eliminates fuel consumption under these conditions as engine momentum is electrically controlled by the ISG unit and the car is ready to re-accelerate on request with no engine restart delay.
