Maruti Suzuki appears to be developing a “Series Hybrid Technology” for its mass-market offerings which is scripted to debut on the Fronx Facelift as the company informed last year.

Maruti Fronx Boosting Strong Hybrid Engine
Ahead of its expected launch by the year-end, the test mule of the Fronx strong hybrid recently spied testing in Gurgaon.
So far, the car manufacturer has two strong hybrid models in its portfolio including Grand Vitara and Invicto.
Both of these models make use of Toyota’s series-parallel hybrid system combining both series and parallel hybrid functions.
Moving ahead this engine can either drive the wheels directly or charge the battery, depending on the driving conditions.
It simply means that the electric motor and engine can work independently or together, optimising efficiency.
While it’s a different story for the Series Hybrid System as the engine doesn’t directly drive the wheels.
Range Extender Hybrid
This system solely works as a generator to charge the battery to provide power to the electric motor, which is actually the only source of propulsion.
It is also known as the “Range Extender Hybrid” as it can potentially improve fuel efficiency, especially in city usage, and reduce emissions compared to traditional ICE vehicles.
Reportedly, Maruti Suzuki is planning to use the brand’s latest 1.2-litre, 3-cylinder Z12E engine with its series hybrid system.
Besides the Fronx, you can also witness this new hybrid setup to power the new Baleno, a Spacia-based MPV (codenamed YDB), and Swift.
In addition to this, Maruti Suzuki is expected to introduce a three-row version of the Grand Vitara (codenamed Y17).
But, the company has planned to continue with Toyota’s more advanced series-parallel hybrid system.
Talking about the upcoming Maruti Fronx Hybrid, it is expected to boast a few cosmetic changes over the ongoing model along with a few new features.
Additionally, it is expected to claim a fuel efficiency of around 35-40 kmpl.
Earlier, Maruti Suzuki was in news as the brand is all set to launch its first all-electric offering, the eVitara, in March 2025.
This launch holds a great significance as it offers extended powertrain options, including petrol, CNG, mild-hybrid, strong-hybrid and electric, thus catering to a wide section of the audience focused on fuel efficiency.
