but i guess arkin, maruti might not be able to source diesel engines from fiat which are bigger, i mean they are already not able to suffice the demand for swift, dzires and ritz, so may be they might be looking to get atleast 1.6L diesel engine, which i have heard that maruti is trying its hands on their home production, or else might borrow from some other company, but one thing is for sure, sx4 needs a diesel heart.
