Ashok Leyland, the Indian flagship of the Hinduja Group, has announced an increase in the prices of its Medium & Heavy Duty vehicle models by about 3% with immediate effect. This will translate into a rise of between Rs. 20,000 in the cost of vehicle on some models up to Rs. 50,000 on others. This price hike has been necessitated to partially recover the increase in the price of raw material like steel, tyres, castings, etc.
