Punch's success marks a growing consumer inclination towards alternative fuel options, which now make up nearly half of the top five car sales. Notably, electric and CNG (compressed natural gas) variants account for 47 per cent of Punch's total sales. Similarly, CNG has become a crucial factor in the sales of Maruti Suzuki's WagonR (45 per cent), Brezza (27 per cent), and Ertiga (58 per cent).
