Indian Autos claims that it has official confirmation of the launch of a BSIV Tavera towards  the end of the year.  There has been a lot of noise about this vehicle which will probably have a new grille and will have the engine sourced from ICML (Sonalika), makers of the Rhino, plonked into its engine bay.  The engine is of 2 litre capacity and makes more power than the existing Tavera engine and is BSIV compliant.
