Maruti Suzuki is actively working on developing its own strong hybrid powertrain for smaller vehicles while continuing to use Toyota’s advanced hybrid technology for its premium hybrid SUVs. Models like the Maruti Grand Vitara, Toyota HyRyder, Innova HyCross, and Maruti Invicto, which are powered by Toyota’s Hybrid System (THS), have gained significant traction in India. These models, produced by Toyota, utilize the more sophisticated series-parallel hybrid system. However, for its compact cars, Maruti is focusing on creating a simpler and more cost-effective series hybrid solution.
Key Differences Between Maruti and Toyota Hybrid Systems
Toyota’s series-parallel hybrid system offers versatility, enabling vehicles to switch between hybrid mode, electric-only mode, and internal combustion engine (ICE)-only mode. While highly efficient, this system is complex, requiring additional components like planetary gear sets and larger battery packs. It also takes up more space and is costlier to produce, making it less suitable for smaller vehicles—a key segment for Maruti.
To address this, Maruti is developing a more straightforward strong hybrid system optimized for compact cars. Unlike Toyota’s setup, Maruti’s system uses a petrol engine solely as a generator to charge the battery, which then powers an electric motor that drives the wheels. This “range extender” setup simplifies production and reduces costs by eliminating the need for the ICE to directly power the vehicle.
The first model to feature Maruti’s new strong hybrid system will be the facelifted Fronx, scheduled for a 2025 launch. This hybrid system will be paired with a 1.2-liter three-cylinder Z12E engine, which is also found in the newly launched Swift. The next-generation Baleno is also expected to adopt this hybrid powertrain.
While this approach is new for Maruti, the technology isn’t entirely unique. Nissan has implemented a similar system in models like the Note hatchback, which received the series hybrid setup in 2016. Although the Nissan Note was tested in India, it never made it to the market.
For its larger SUVs, Maruti will continue to utilize Toyota’s strong hybrid technology. However, Maruti’s in-house hybrid system could be a game-changer for compact vehicles in the competitive sub-4-meter segment, where brands like Tata Motors and Hyundai are also focusing their efforts.
Maruti’s comprehensive powertrain options—including petrol mild hybrids, CNG, pure petrol, and Toyota-sourced strong hybrids—allow the company to adapt to the evolving automotive landscape. With the upcoming launch of the eVX electric SUV by the end of the year, Maruti is positioning itself as a versatile player during this transitional period in the industry.
