Asia Bizz: The demand for diesel cars might have gone up due to the rising prices of petrol, but these days certain ambiguity in the prices of the diesel, has forced the car makers to hold back their plans to expand their segment in diesel.

Several car makers including Maruti Suzuki is now forced to go slow or even abandon the plans to expand the diesel segment due to the uncertainty. In the past few months, it was observed that the demand for the diesel cars have gone up and the petrol cars are available at heavy discounts due to a drop in sales.

So as to escape from the ambiguity in the prices of diesel and petrol, companies like Mahindra & Mahindra and Tata, who are known for their diesel models, are now planning to come up with new petrol cars.
