Baleno with updated alloy wheels - What is Maruti testing?

A mysterious Baleno test mule has been spotted in Gurgaon. The test car appears to be based on the pre-facelift version of the hatchback, but it is riding on updated alloy wheels.

All the badges on the car have been tapped off. So, it's difficult to guess what Maruti could be testing.

Could they be testing the BS6 1.5L Diesel?

Reports suggest that Maruti could re-introduce the 1.5-litre diesel engine in BS6 guise sometime in 2021. The same engine could also power some Toyota branded cars in the future.

Could they be testing a proper hybrid with tech sourced from Toyota?

A Baleno with a full-hybrid powertrain was spotted testing back in July 2019. Maruti is said to be developing the 48 Volt "strong hybrid" powertrain in collaboration with Bosch.

Could they be testing an electric powertrain?

In 2018, Bosch had showcased a Baleno-based EV. It came with an electric motor that had an output of 115 BHP and 200 Nm and was powered by a 10 kWh battery pack.
