Tata Altroz power and torque explained
The Altroz hands you three engines to weigh up, more than most hatchbacks offer. There is an 88 PS 1.2 petrol, a 74 PS 1.2 CNG, and a 90 PS 1.5 diesel.
They pull in very different ways. The petrol and the CNG both want some revs before they feel strong. The 1.5 diesel is the opposite, doing its hardest work from very low down.
How to read this chart. Torque is the push you feel when you accelerate, and it peaks low on the rev range. Power is how hard the engine keeps pulling as it revs higher, and it peaks further up. The two dots mark those peaks. The shaded strip between them is the flexibility band: a wider band pulls easily across more revs and feels relaxed in traffic, while a narrower band asks you to rev the engine more to get its best. Use the buttons above to compare this car's engines.
Peak figures come from the 1.2L Revotron iCNG spec sheet. The line between the two peaks is not a measured dyno curve.
The 1.2 petrol is the all rounder of the range, making 88 PS. Its 115 Nm of torque peaks at 3250 rpm, while full power arrives high up at 6000 rpm. That leaves a wide 2750 rpm spread between the two peaks, so one gear stretches from a town crawl to a quick overtake. It feels a touch lazy right off idle, then comes alive as you rev it past the middle. Pick this petrol if your days are mostly city miles and you want a smooth engine with manual, AMT or DCA choices.
The 1.2 CNG makes 74 PS and 103 Nm, the gentlest tune of the three. Its torque peaks at 3500 rpm and power at 6000 rpm, leaving a 2500 rpm band between them. So you plan ahead and let it rev when you want to build speed, rather than expecting a hard shove low down. It is happiest on calm city runs where the low fuel bill is the real prize. If that cheap running draws you in, it pays to see how far the Altroz travels on a kilo of CNG before you choose.
The 1.5 diesel is the muscle of the Altroz and the reason to drive far. It serves up a big 200 Nm, by far the most here, and holds all of it from just 1250 rpm to 3000 rpm. So the strongest pull is there the moment you set off, and it stays with you as speed builds. Its 90 PS power peak lands low at 4000 rpm, so you never need to rev it hard on the highway. That leaves a wide 2750 rpm span between the torque and power peaks, so one relaxed gear covers most of your driving. This is the engine for long motorway runs and loaded family trips, where it cruises with almost no effort. Once it wins you over, see what the diesel Altroz costs on the road in your city before you settle on a trim.
