LONDON, England – Suzuki Britain is to add three 48-volt self-charging hybrid derivatives to its range in early 2020 along with a K14D Boosterjet petrol engine.
The automaker says its new Hybrid Powertrain is in line with plans to further reduce CO2 emissions across its entire model range.
The changes will involve Swift Sport, Vitara, and S-Cross units with a target of as much as 20% less CO2 emissions, better torque, and a 15% reduction of fuel consumption. These models, Suzuki adds, will replace the current 1.4-litre Boosterjet manual derivatives.
The new 48V Hybrid Powertrain is said to be ”very lightweight” in design and the components add less than 15kg to the overall weight of the vehicle.
The powertrain is similar in basic principle to the Suzuki 12V Hybrid SHVS (Smart Hybrid Vehicle by Suzuki) system that the brand pioneered in 2016 and fitted to all manual transmission Ignis and Swift SZ5 models,
The new and higher-powered Suzuki SHVS system consists of a 48V lithium-ion battery, starter/generator and 48V-12V (DC/DC) converter to power lights, audio, and aircon.
The starter/generator is belt-driven and assists the petrol engine during launch with more torque (235Nm) from 2000rpm.
The compact and high-performance lithium-ion battery stores electrical energy recovered from deceleration and braking and incorporates an idle/stop function. This battery and the DC/DC converter unit under the front seats to assist overall weight distribution.
A further benefit of the new 48V Hybrid system, Suzuki says, is the introduction of electric motor idling when the clutch is disengaged and the engine speed is about 1000rpm. This replaces fuel-injection with power from the electric motor to then control and maintain engine idling at vehicle speeds below 15km/h and when stationary.
This function 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.
- More details and full specifications of the three new UK Hybrid models will be announced in advance of media and public launches in March 2020.
