In a major blow to the automobile industry in India, the Supreme Court on Wednesday banned registration of all diesel-run SUVs and luxury cars with engine capacity of 2000cc in Delhi and National Capital Region (NCR).

The ban, which will be effective till 31 March, 2016, has been issued in the wake of increasing pollution in Delhi, which has been ranked as the world's worst polluted city by the World Health Organisation.

The key question now is which cars fall under the ban criteria. We have compiled a list of vehicles that cannot be registered in Delhi till 31 March. Mahindra and Mercedes-Benz seems to have been affected the most by the ban. The best-selling SUV in India, the Bolero, cannot be registered in Delhi along with the Scorpio and XUV500. All three of these SUVs are among the top ten best-selling SUVs in India that will see a dent in sales.

On the other hand, Mercedes-Benz uses above 2000cc diesel engine right from its most affordable A-Class hatchback. Almost the entire line-up of the German manufacturer is affected by the ban. The worst affected manufacturer would be the Mitsubishi India. Mitsubishi sells only one product, the Pajero Sport, which is an SUV as well as comes with over 2000cc diesel engine.
