It&#8217;s a 1.2L, three-cylinder, naturally aspirated gasoline engine that provides an excellent balance of performance and fuel economy. It has 86.79 bhp output and 115 Nm torque. Although a 5-speed manual transmission is a standard feature, the Altroz also comes equipped with a 6-speed DCT (Dual-Clutch Transmission), which makes it one of a very select number of cars in its class that provide this future-tech feature.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"1-2-litre-i-cng\">1.2-litre iCNG<\/h3>\n\n\n<p>The<a href=\"https:\/\/www.spinny.com\/blog\/tata-altroz-cng-launched-at-rs-7-55-lakh\/\"> Altroz iCNG<\/a> gets its 1.2L gasoline engine, albeit with a factory-installed CNG kit. Thanks to Tata&#8217;s &#8220;twin-cylinder&#8221; innovation, its CNG tanks are located under the boot floor. Brilliantly, this resolves CNG cars&#8217; largest disadvantage, limited trunk space, freeing up much of the trunk. In CNG, its engine generates 72.49 bhp power and 103 Nm torque, and it comes with a 5-speed manual.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"1-5-litre-turbo-diesel\">1.5-litre Turbo Diesel<\/h3>\n\n\n<p>The diesel version of Altroz uses a 1.5L turbocharged, four-cylinder Revotorq engine. This is an all-workhorse engine that delivers excellent power and mandatorily good fuel economy. The engine produces 88.76 bhp power and a class-leading 200 Nm torque. Its torque superiority ensures that it can cruise well on highways and tackle uphill stretches effortlessly. A 5-speed manual transmission comes with it.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"official-vs-real-world-mileage-as-of-2025\">Official vs. Real-World Mileage (as of 2025)<\/h2>\n\n\n<p>The ARAI figures provide a standardised benchmark, but real-world performance is what truly matters.

The power of the petrol engine is weak on highways, particularly when fully loaded, and downshifting is commonplace for overtakes. The DCT variant provides easy and comfortable driveability, perfect for city service. It holds an uncompromised 345-litre boot.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"cng\">CNG<\/h3>\n\n\n<p>Even its CNG variant carries through the character of the petrol engine, but its power is reduced slightly. It is enough and then some for city duty, but it feels less spirited out on the highway. Its key practical advantage is Tata&#8217;s twin-cylinder technology, which has a 210-litre usable boot capacity, far superior to typical CNG installations.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"diesel\">Diesel<\/h3>\n\n\n<p>Its 1.5L diesel is the highest-powered variant, boasting excellent torque, and it is an easy cruiser on highways. It\u2019s a smooth ride that can maintain high speed and climb hills without effort. A long-haul driver\u2019s favourite, it also has an uncompromised 345-litre boot.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"the-verdict-which-altroz-is-for-you\">The Verdict: Which Altroz is for You?<\/h2>\n\n\n<p><strong>For the All-Rounder (Moderate Use):<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Best Pick: Tata Altroz Petrol.<\/strong><\/li>\n\n\n\n<li><strong>Why:<\/strong> With an average city commute and a liking for an inexpensive outlay and a car that is a blast to drive, the petrol Altroz is the perfect solution.
