    Water is a byproduct of combustion. The air coming from the engine is super heated and the exhaust system is significantly cooler relatively, and so the air condenses on its way through the system. Water and steam from the tailpipe is normal and to be expected when temperatures drop.

      Then why a diesel car does not emit water in the same way?

      Kerosene, diesel, and, as you asked about, petrol all involve different mixes of hydrocarbon chains which change based on temperatures. Is it possible you just never noticed it before with the diesel? Are you sure it is water. Does it smell sweet?
