Letter from J J Irani, Tata Motors

September 20, 2017

You may recall that during our interaction at the Track II Meeting in Delhi just over a month ago, I had mentioned to you that the bias against the use of diesel in automobiles may be unjustified as with cleaner fuels now available and the upgradation in the efficiency of diesel engines, the difference between them and engines which use petroleum may be marginal. You were not convinced of this view, and maintained that diesel engines, by their very nature, are more polluting than the petroleum engines now available.
