Brezza cng has very less or negilgible boot space. Also, Maruti removed Hill Hold Assist from its CNG variant. I think Maruti doesn't need customers nowadays days If we think about the Brezza petrol variants Maruti removed smart hybrid from LXI and VXI also. Petrol variants(lxi and xvi)now claim very little mileage. If you are looking for cng car in this range nexon cng with iCNG and twin cylinders may be the best alternative to brezza cng. Nexon is fully loaded with safety features and comfort features.
