In 1992, the Saga was given a facelift and its name expanded as Proton Saga Iswara (also known in short as Proton Iswara), after a species of butterfly in Sarawak. Modifications included slimmer headlights, plastic bumpers, side mouldings, coloured door handles, grooved taillight clusters and rear number plate repositioned to the bumper.
This particular model is used as taxis in Malaysia and some are converted to NGV. Due to the modification, boot space was reduced by half to accommodate the NGV tank and there are only a few petrol stations by Malaysian oil-giant Petronas in the Klang Valley that sell natural gas, although there are plans underway to increase the number of stations selling it at various locations around Kuala Lumpur.
Models exported to Singapore and the United Kingdom were available with multi-point fuel injection and catalytic converters to meet Euro I emissions standards. This model was known as the Proton MPi in the United Kingdom. The introduction of the Proton Persona in 1993 replaced the corresponding models in the Saga range in the United Kingdom and this continued until the entire range was replaced in 1996.
In 2001, to regain sales and be competitive with Perodua, Proton introduced a special edition of Saga Iswara Sport based on the Aeroback version which included a new bodykit, jewel-effect headlights and Altezza lights, among other changes. It was only available in silver, with a manual transmission and a 1.3-litre engine. The original Saga Iswara Aeroback was still available in a 1.5-litre engine.
While the Iswara Aeroback underwent further modifications in the domestic market to become the Saga LMST in 2003, the saloon variant remained on sale unchanged.
