The Tata Tigor (facelift 2020) 1.2L Revotron (86/73 hp) iCNG is a subcompact sedan produced by the Indian manufacturer Tata Motors. Introduced in January 2022, this variant represents a significant step in offering a factory-fitted Compressed Natural Gas (CNG) option within the Tigor lineup. It’s positioned as an entry-level to mid-range offering, appealing to budget-conscious buyers seeking fuel efficiency and lower running costs. The Tigor itself is built on the XO platform, a modified version of the Tata Motors’ earlier X1 platform, and the 2020 facelift brought updated styling and features to the model range.
The 1.2L Revotron iCNG: A Detailed Overview
The iCNG variant of the Tigor utilizes Tata’s 1.2-liter Revotron engine, specifically tuned to run on both gasoline and Compressed Natural Gas. This dual-fuel capability allows drivers to switch between fuels depending on availability and cost. The introduction of the iCNG technology aimed to address growing concerns about fuel prices and environmental impact, providing a more sustainable and economical transportation solution. The Tigor iCNG was a key part of Tata’s strategy to expand its alternative fuel offerings in the Indian market.
Powertrain & Engine Architecture
At the heart of the Tigor iCNG lies the 1.2-liter Revotron inline-3 cylinder engine. This engine, designated as the Revotron series, features a multi-point fuel injection system for gasoline operation. When running on CNG, the engine management system automatically switches to the CNG fuel delivery system. The engine produces 86 horsepower at 6000 rpm when running on gasoline and 73 horsepower at 6000 rpm when running on CNG. Torque figures are 113 Nm (83.34 lb-ft) at 3300 rpm on gasoline and 95 Nm at 3500 rpm on CNG. The engine’s configuration is naturally aspirated, meaning it does not employ turbocharging or supercharging. The engine displacement is 1199 cm³ (73.17 cubic inches). The engine oil capacity is 3.5 liters (3.7 US quarts / 3.08 UK quarts) and requires a specific oil specification (details not publicly available without logging into Tata’s service portal). The cooling system requires 5.5 liters (5.81 US quarts / 4.84 UK quarts) of coolant. A Start & Stop system is integrated to further improve fuel economy.
Driving Characteristics
The driving experience in the Tigor 1.2L iCNG differs noticeably between gasoline and CNG modes. On gasoline, the engine provides adequate power for city driving and occasional highway use. However, the switch to CNG results in a slight reduction in power and torque, making acceleration feel less responsive. The 5-speed manual transmission is the only gearbox option available with this engine. Gear ratios are tuned for fuel efficiency rather than outright performance. The iCNG variant is best suited for urban commutes and shorter trips where fuel economy is a priority. The reduced power output on CNG is most apparent when the vehicle is fully loaded or climbing inclines. The suspension is tuned for comfort, providing a relatively smooth ride, but it can feel somewhat soft during spirited driving.
Equipment & Trim Levels
The Tigor iCNG was offered in several trim levels, typically including XE, XM, and XZ. Standard equipment across most trims included air conditioning, power steering, and basic safety features like dual airbags and ABS (Anti-lock Braking System). Higher trim levels, such as the XZ, added features like a touchscreen infotainment system, alloy wheels, and rear parking sensors. Interior upholstery was typically cloth, with color schemes varying depending on the trim level. Optional extras included a rear defogger, electrically adjustable mirrors, and a driver information system. The dashboard layout was consistent across the Tigor range, with a focus on functionality and ease of use.
Chassis & Braking
The Tigor iCNG utilizes a front-wheel-drive layout. The front suspension is an independent McPherson strut type, providing a reasonable level of ride comfort and handling. The rear suspension employs a torsion beam setup, which is a cost-effective solution for subcompact sedans. The front brakes are disc brakes, while the rear brakes are drum brakes. This configuration is typical for vehicles in this price segment. The steering system is an electric power steering rack and pinion, offering light and easy steering feel. The Tigor iCNG rides on 175/65 R14 tires mounted on 14-inch steel or alloy wheels, depending on the trim level. The vehicle has a ground clearance of 165 mm (6.5 inches).
Market Reception & Comparison
The Tata Tigor iCNG received generally positive reviews for its fuel efficiency and affordability. Critics praised Tata Motors for offering a factory-fitted CNG option, which provided a convenient and reliable alternative to aftermarket conversions. Compared to the gasoline-only Tigor variants, the iCNG model offered significantly better fuel economy, particularly in city driving conditions. However, the reduced power output on CNG was a common criticism. Compared to other CNG-powered vehicles in the Indian market, the Tigor iCNG was considered a competitive offering, offering a good balance of features, performance, and price. The BS6 Ph2 emission standard compliance was also a positive point, demonstrating Tata’s commitment to environmental responsibility.
