In a report released by Dun & Bradstreet, the auto sector is set to maintain its momentum in 2017 across all categories. Admitting that there will be some uncertainly around GST, and because of the impact of demonetisation, growth in 2017 as far as commercial vehicles are concerned, will be driven by replacement demand, the report mentions. Stressing upon 7.7 per cent growth achieved by the commercial vehicle industry in 2016, the report mentioned that sales growth will also be driven by construction and mining, increasing freight movement, moderation in fuel prices and firm freight rates. As per the report, increased government focus on infrastructure will drive demand for specialised heavy goods vehicles.
