India-bound self-charging 48V SHVS variant of S-Cross showcased at Vienna Auto Show

Suzuki Motor has developed a new 48-volt self-charging hybrid system that it will introduce in models including Swift Sport, Vitara and S-Cross from March 2020. The new hybrid system offers up to 20 per cent lower CO2 emissions, better torque and 15 per cent overall improvement for the same engine. The 48V hybrid system just adds 15 kg to the overall weight of the vehicle.

A long-time friend and Austrian follower Raphael Gürth sent us these exclusive photographs of the Suzuki S-Cross ‘Hybrid’ and the Suzuki Vitara ‘Hybrid’ from the 2020 Vienna Auto Show.

The latest development of the SHVS (Smart Hybrid Vehicle by Suzuki) consists of a 48V lithium-ion battery, Integrated Starter Generator (known as ISG) and 48V-12V (DC/DC) converter to power components requiring lower voltage including lights, audio and air conditioning. As a natural progression to the current 12V system, the new system is more powerful and offers additional torque up to 235 Nm available from 2,000rpm.

The benefits of the 48V system is that it will offer up to 20 per cent lower emissions, extra torque, and 15 per cent higher fuel efficiency for the same engine.

The 48V hybrid system sees the introduction of electric motor idling when the clutch is disengaged and the engine speed is approximately 1,000 rpm. Replacing the fuel injection, the motor controls and maintains engine idling at low vehicle speeds and when stationary.

In India, Maruti Suzuki offers the 12V SHVS system with petrol models of Ciaz, Baleno and Ertiga. Media reports in the past have pointed to MSIL gradually switching to higher voltage systems to keep improving fuel efficiency and meet higher emission norms. While there is no confirmation yet for this system’s launch in India, we can expect Maruti to talk about ‘stronger’ hybrids during the advent of the tighter CAFE norms around 2022.

Suzuki will make use of its upcoming Gujarat battery manufacturing plant for the production of its next-generation hybrid systems. Phase 1 of the plant is set to start operations by the end of 2020.
