- New K14D petrol engine to replace the existing K14C range.
- New 48V self-charging powertrain to be 15 percent more fuel-efficient.
- Maruti Cars with this system to run exclusively on electric mode up to 16kmph.
Maruti Suzuki is working on an all-new 48V self-charging motor for a few of its upcoming models in the Indian market. It is expected that Swift, S-Cross and Vitara Brezza will be powered by this new 48V hybrid setup. Internationally, the new powertrain setup will be offered with the 1.4L turbocharged K14D Boosterjet petrol engine which will replace the ongoing K14C range of engine in the Indian market.
Maruti Suzuki engineers are of the view that K14D engines are capable of cutting down the CO2 emission levels by up to 20 percent while at the same time being fuel-efficient by up to 15 percent. In addition, the 48V system will also assist in torque generation.
For those asking, the K14D powertrain is being nearly 15 kgs lighter than the K14C which subsequently results in improved performance due to the better weight-to-output ratio. Hence, the company might also introduce this system to its premium range of vehicles as well.
The foremost components of the new K14D petrol engine include the 48V Lithium-ion battery, an Integrated Starter Generator (ISG) and a 48V-12V converter. The ISG plays a substantial role in generating low-end torque - 235Nm from as low as 2000rpm. Additionally, the cars with a K14D petrol engine with a 48V battery will run on all-electric mode up to the speeds of 16kmph. Presently, a few Maruti Cars such as Ertiga, Ciaz, S-Cross, Baleno, and XL6 boast of SHVS (Smart Hybrid Vehicle by Suzuki) mild-hybrid technology with both petrol and diesel engines.
