Some of the auto websites in their enthusiasm had alluded to the fact that the soon to be launched Eon from Hyundai India will replace the Santro.  Hyundai India has clarified that that will not be the case.  The Eon will become the new entry model to take on the Maruti Alto and the higher specced versions of the Tata Nano.  The engine on the Eon is supposed to be a three pot version of the 1100 cc engine that does duty on the Santro and will displace 814cc with power estimated to be around 50 PS.  The dimensions of the car are almost identical to those of the Alto though it will have a little more room on the inside.
