CNG cars aren't new. Customers walking away from CNG cars due to lack of boot space isn't new either. Addressing the issue, Tata Motors has introduced twin-cylinder technology in its premium hatchback Altroz. This has resulted in freeing up of considerable cargo volume, which allows room for handy luggage. Moreover, this technology in due course of time will flow down to the Punch i-CNG as well.

CNG as a fuel type is driving close to 40% sales in Tiago and Tigor, which are also available in electric avatars. Hence, an Altroz or a Punch i-CNG was always on the cards. For all these cars, the 1.2-litre revotron petrol engine powers them. In terms of technology, Tata's CNG iterations have an edge over the market. Firstly, the ECU mapping for the CNG and petrol fuel are the same. The driver can choose to crank up the engine and drive in CNG mode without relying on petrol. Secondly, there is a sensor on the fuel flap, which inhibits the car from starting in case one misses out on shutting it.

The engine in CNG mode generates 73.5 PS and 103 Nm of peak torque. The engine is mated to a 5-speed manual transmission. The initial gear throws are short, which means start-stop traffic would call for quick gear shifts. Overtaking in traffic comes easy due to a good amount of usable torque at the bottom-end. However, unlike petrol, the engine can't be revved hard when CNG acts as a fuel. In terms of mileage, which is still to be accredited by the rating agency, is expected to be significantly lower than Baleno and Glanza CNG (30 km/kg).

Suspensions, brakes, and other mechanicals remain identical to the petrol avatar. The CNG cylinders have increased the weight of the vehicle. Overall, the ride stability feels more planted on highways and assuring in uneven roads.

Creatures comforts are playing a pivotal role in Tata Altroz iCNG. Available in 5 trims, the top-of-the line XZ+ optional retails at Rs 10 lakh (ex-showroom). Sunroof introduction to a CNG car is also a novelty in Altroz. Sun roof, which starts with the XM+ trim, seeks a premium of Rs 45,000. Also, as you climb up the ladder, features appear significantly greater than Baleno and Glanza, where factor-fitted CNG is only available in mid-trims. Things like cooled glovebox, wireless charging and rain-sensing wipers are supplied to the Altroz. Seat ventilation for the black leatherette seats should have been considered in the range-topping trim.

Overall, Tata Motors is spicing up the market with the flurry of alternative-fuel cars. Altroz i-CNG changes the optics of how we see CNG cars. Finally, it's time to have a CNG car with a boot space which finds space in your garage.
