Today, we'll compare electric vehicles (EVs) and CNG cars. As EVs gain popularity, many wonder if they save money over time compared to traditional CNG models. To explore this, we tested two versions of the Tata Tiago— the Tiago EV and Tiago CNG— to see which one costs less when considering both purchase price and running expenses. During our test drive, we took both cars on city roads and highways. Before starting, each car was either fully charged or filled with CNG. Our aim was to calculate the cost per kilometer for each vehicle and see how long it takes for the EV’s higher upfront cost to pay off through savings. Refueling is easier with the CNG Tiago. CNG stations are everywhere, so refueling is quick and simple. On the other hand, the EV benefits from growing charging infrastructure. It offers a smoother ride and is quieter and more comfortable than the CNG model. While CNG refueling is convenient, the EV provides a better driving experience overall. There are some drawbacks to the CNG version. Its acceleration is slower, especially when overtaking. It also gets noisier during city driving. The Tiago EV runs more smoothly, with little engine noise and less lag in power, making it more fun to drive. Range worry can affect EV drivers. In our test, the Tiago EV covered about 169 km on a full charge. After 56 km of driving, the remaining range was 133 km. Although it was not a big issue, the driver felt a little uneasy about the range indicator. CNG drivers do not worry about this because fuel stations are everywhere. Now, let’s talk about costs. Charging the Tiago EV at home costs roughly ₹1.6 per km. Fast charging increases that to ₹3.75 per km. The Tiago CNG costs around ₹3.78 per km to run. Even with a higher initial price, the EV tends to save money over time, especially for daily drives of about 100 km. Its lower running costs make it cheaper in the long run, despite a bigger initial spend. In the end, if you drive less than 50 km each day, the CNG Tiago is a good choice. It costs less upfront and has lower operating costs. But if your daily drive is longer, the EV pays off over time. It saves money, offers more comfort, and charging stations are increasing. To wrap it up, the CNG Tiago works best for those who drive less often and want a cheaper initial buy. The EV is better for drivers who want to save money in the long run and enjoy a quieter, more efficient ride.
