The company, which last week introduced the refreshed version of its popular hatchback Swift with 10 per cent enhanced fuel efficiency, will launch the new Alto K10 on Monday that will be 15 per cent more fuel efficient than the existing variant.
"Fuel efficiency is always on the top of our mind. For any model upgrade, we always try to improve it," Maruti Suzuki India (MSI) Executive Director, Engineering, C V Raman told PTI.
"Various steps like increasing thermal efficiency, reduction of frictional loss and usage of low viscosity engine oil have been taken up to improve mileage," Raman said, adding the fuel efficiency had been achieved by working on engines alone and not through aerodynamics.
When asked if refreshed versions of other models and future models that would use the current series of engines could also undergo similar change, he said: "This is a moving target that we have to meet customer demands to achieve top of the mileage."
