Smart hybrid lacks in vxi and lxi variants

My friend owns vxi petrol with a smart hybrid it gives descent mileage of about 18 km per litre. I wanted to purchase same but Maruti removed smart hybrid from its Vxi and Lxi variants. LXI or VXI variants without smart hybrid will give about 15km mileage. This is very disappointing. Other companies are adding more features and Maruti is reducing features I am totally disappointed by this.
