Leading passenger car maker Maruti Suzuki is all set to come up with CNG compatible variants of its leading models across segments soon. It plans to introduce CNG variant of its recently upgraded Wagon R hatchback within the next three months, which could be about Rs70,000 costlier than the existing version. Maruti has an LPG variant of the Wagon R. "The movement is undoubtedly towards CNG and LPG powered vehicles in the times to come. Initially customers would be apprehensive as the cylinder would eat up boot space, but with rising petrol and diesel prices, the shift has to be towards these greener vehicles along with more fuel efficient vehicles. With our new K-series engine we are now able to offer around 10-15 per cent higher mileage compared to conventional engines", said Partho Banerjee, general manager, marketing strategy & development of Maruti Suzuki India Ltd. Popular models like Alto, Eeco, Estilo and SX4 are likely to be powered by CNG fuel.
