Now that there’s a large cylinder taking permanent housing in the boot, the rear suspension of the Tigor seems to have undergone some tweaks. These reworked suspensions prattle more than usual over bad and unpaved roads, but you can hear them more than feel. Over rutted and irregular surfaces, the Tigor CNG goes over like any other Tata ought to. Despite the added weight, the ground clearance is fairly good at 165mm and this is one sedan that you won’t have to think about when encountering larger speed breakers. Meanwhile, going three full turns lock-to-lock, the steering is smooth and progressive but isn’t something that would be happy on fast twisties. But that’s alright, this car isn’t meant to offer driving dynamics, but is a comfortable runabout and does that job fairly well.

Not much has changed in the cabin of the refreshed MY22 Tigor. Even in this i-CNG, there’s a CNG button added to the strip of buttons on the centre console and a new CNG fuel bar added to the all-digital instrument cluster. Moreover, the cabin now adopts a new dual-colour black-beige theme. That’s where the changes end. So, the Tigor’s cabin continues to be a spacious and practical one. There’s right support offered from cloth-draped seats with good visibility all around. It’s got a surprisingly good amount of headroom both in the first and second row.

The seats at the back are soft and might sink in the longer run, but otherwise, they have good support for three people. There’s no adjustable headrest at the back but the ergonomics won’t give a reason to complain.

You do get a cup holder and folding armrest, but no seatback pocket. Lastly, the boot space was one of the highlights for the Tigor. At 419 litres, it was commendably more than what was expected from the segment. And now, with the instalment of CNG tank in the boot, it has gone for a toss to an extent. But it’s still not meagre, offering 205 litres, which is more than ample for a couple of duffle bags with little room to spare.

Apart from the inclusion of i-CNG in the line-up, Tata has also upgraded the variant offering of the Tigor (and Tiago). The pair now gets a new range-topping XZ+ trim with a whole lot of new features added to the already long list. This includes rain-sensing wipers, auto headlamps with projectors, black-roof with spoiler, and 15-inch alloy wheels (i-CNG gets 14-inch steel rims). Other than that, there are bits and pieces added to the top-spec XZ+, like shark fin antenna, tri-arrow grille, LED daytime-running-lights, a seven-inch infotainment screen with Apple CarPlay and Android Auto, automatic climate control, digital instrument cluster, cooled glovebox, auto-fold ORVMs, engine start-stop button, and more that make the Tigor stand out.

As for safety, the Tigor is already a four-star NCAP rated. With the iCNG, there’s a provision of a fire extinguisher under the front passenger seat as is mandatory for all CNG cars. There’s also a microswitch that automatically turns off the engine when the fuel cap is opened and the motor won’t start as long as it’s open. The CNG cylinder also gets a leak and thermal protection along with a pressure release nozzle. Other standard safety equipment includes dual airbags, ABS with EBD and corner stability control, a rear parking sensor with camera, and a puncture repair kit.
