German luxury carmaker BMW on Thursday said it is working to make its petrol portfolio in India compliant to the BS-VI emission norms ahead of the schedule. The automaker on Thursday launched the petrol version of its Coupe X6 M Sport at Rs 94.15 lakh. It also introduced updated versions of M3 sedan and M4 Coupe priced at Rs 1.3 crore and Rs 1.33 crore, respectively (all prices ex-showroom). “We are working towards making our petrol portfolio BS-VI norms compliant over the next few months,” BMW Group India president Vikram Pawah told reporters. Although shift to the BS-VI emission norms kicks in from April 2020, many automakers are trying to get their products conform to new regulations ahead of the schedule.
