Tata's CNG portfolio which consists of the Tiago and Tigor has now been joined by the Altroz. The introduction of the Altroz i-CNG at Rs. 7.55 lakh (ex-showroom) means competition to the Maruti Suzuki Baleno and the Toyota Glanza, both of which are currently offering a CNG model. Thus, it's only getting better for prospective buyers to have more options. Here's a picture gallery of the new Altroz CNG's interior.
