Maruti's entire line-up at present runs on the F and G series petrol engines which are Euro-3 compliant.These engines are going to be phased out by 2010.
Maruti will start manufacturing new K-series engines in India by the end of this year.The new launches[like the a-star] would be getting the K-series engines which are euro-5 compliant.Existing models would get the new engines in phased manner.This includes the recently launched Dzire[petrol].
The sx4 already has the new M-series engine which is euro-4 compliant and can also be made euro-5 compliant and hence would not see a change.Diesel engines[swift hatch,dzire] are also not going to see this change.
What interested be most is that the article mentions the wagon-r,swift and estilo to be present in 2010 but no mention of the Maruti 800 and the Alto.Does this mean they would be phased out for newer models.Probably yes.
