What will happen to maruti suzuki if they drop the diesel vehicles?

As of now maruti suzuki has around 50% of market in india with their vehicles and in the recent iteration they have proved themselves with their new vehicles like new swift&dzire,baleno,wagon r,ertiga and the sales figures brezza has achieved.But this story might turn around like,if they drop the diesels they will have only petrols,they also reported that they are doing some modifications to the newly brought 1.5 lit diesel engine and if it is able to tick the regulations of the BS-6 norms then it will stand else it also has to go to the shed.

Here the main thing is there will be a huge drop in their sales figures and most of all indians were so obsessed with the maruti suzuki's vehicles in terms of their offerings,features,mileage their vehicles give and many like this and it creates some kind of shock to the customers for those who plan to buy a new maruti suzuki in the upcoming times.But i don't think they will have any big problem as they mentioned that they are working on the new 225 ddis engine and if it successfully satisfies the BS-6 then they can incorporate this engine in their vehicles,due to this engine there are two cases which can happen.

1.If they detune this engine and install in their vehicles according to the vehicle,then there is a chance to increase the prices for every vehicle if  they install this engine.

2.If they simply incorporate this engine with the same power and torque and re-arrange the prices,then there will be huge increase in the prices and if the 1.5 lit engine fails to satisfy the norms of the bs-6,then they will have to create new engines that satisfies these norms.
