Analysts believe Maruti's move to stop manufacturing diesel cars could result in loss of market share. "We see risk to Maruti's market share and expect it to decline 200 bps over FY19-22 on exit from diesel segment and limited portfolio gaps in existing segments," analysts at Axis capital said. Citing huge costs of upgrading diesel engines to be compliant with BS-VI emission norms, Maruti had announced it will stop manufacturing them, but will evaluate options of 1.5 litre diesel engines. SUVs account for over 25% of the total car sales, with average monthly volumes ranging between 85,000-1 lakh units. While Maruti holds over 60% market share of the passenger cars, it's share in the SUVs stands at around 24%. With most of the SUVs and MPVs converted to petrol engines, there is a risk of Maruti losing market share as rivals including Hyundai, Mahindra & Mahindra will continue selling diesel cars.
