Tata Tiago NRG (facelift ) 1.2 Revotron (8673 Hp) iCNG

The Tata Tiago NRG (facelift 2020) 1.2 Revotron, powered by an 86/73 horsepower engine and capable of running on both petrol and Compressed Natural Gas (CNG), represents a specific variant within the broader Tata Tiago lineup. Introduced in 2020, this model aimed to offer a more rugged, crossover-inspired aesthetic combined with the fuel efficiency benefits of CNG, targeting a segment of buyers seeking affordability and practicality. It sits within the Tiago range as a more stylized and feature-rich option compared to the standard hatchback, but below the more premium offerings from Tata Motors.

Powertrain & Engine Architecture

At the heart of the Tiago NRG is the 1.2-liter Revotron engine, a three-cylinder, naturally aspirated gasoline engine. This engine, designated with the Revotron code, produces 86 horsepower at 6000 rpm when running on gasoline, and a slightly reduced 73 horsepower at the same engine speed when fueled by CNG. The engine boasts a power-to-liter ratio of 71.7 hp/l on petrol and 60.9 hp/l on CNG. Torque output is 113 Nm (83.34 lb-ft) at 3300 rpm on gasoline, decreasing to 95 Nm when operating on CNG. The engine utilizes a multi-port manifold fuel injection system, a common setup for this class of vehicle, and features 4 valves per cylinder. 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 4 liters (4.23 US quarts / 3.52 UK quarts) of coolant.

A key feature of this variant is its compatibility with CNG. The iCNG technology allows the vehicle to seamlessly switch between petrol and CNG fuel sources, maximizing fuel efficiency and reducing emissions. The CNG system incorporates a 60 kg capacity cylinder. The engine is equipped with a Start & Stop System, further enhancing fuel economy during city driving.

Transmission

The Tiago NRG 1.2 Revotron is equipped with a 5-speed manual transmission. While an automatic transmission option was available on some Tiago models, it was not offered with the CNG variant. The manual gearbox is geared towards maximizing fuel efficiency and providing adequate performance for urban and highway driving. Specific gear ratios are not widely published, but are typical for a small displacement, economy-focused vehicle.

Driving Characteristics

The driving experience in the Tiago NRG 1.2 Revotron is characterized by its light steering and relatively soft suspension. The 86 hp output provides adequate power for everyday driving, but acceleration is not particularly brisk. The CNG mode results in a noticeable reduction in power, making it more suitable for city commutes than high-speed highway travel. The 5-speed manual transmission allows drivers to maintain optimal engine speed for fuel efficiency or to extract more power when needed. The vehicle’s weight-to-power ratio of 12.8 kg/hp and weight-to-torque ratio of 9.7 kg/Nm contribute to its manageable handling characteristics. The engine delivers its peak torque at 3300 rpm, providing a usable powerband for most driving situations.

Equipment & Trim Levels

The Tiago NRG (facelift 2020) 1.2 Revotron typically included features such as air conditioning, power steering, and an audio system as standard equipment. The NRG trim level, in particular, added distinctive exterior styling elements like black plastic cladding, roof rails, and a more aggressive front grille, giving it a crossover appearance. Interior features included fabric upholstery and a basic dashboard layout. Optional extras could include alloy wheels, a touchscreen infotainment system, and rear parking sensors. The interior space is designed to comfortably accommodate five passengers, making it a practical choice for small families.

Chassis & Braking

The Tiago NRG utilizes a front-engine, front-wheel-drive layout. The front suspension consists of a coil spring, independent McPherson strut setup, providing a comfortable ride. The rear suspension employs a torsion beam axle, a cost-effective and space-efficient solution. The braking system features disc brakes on the front wheels and drum brakes on the rear wheels. Anti-lock Braking System (ABS) is included as a standard safety feature. The steering system is an electric power steering rack and pinion, offering light and precise steering control. The vehicle rides on 175/65 R14 tires mounted on 14-inch steel or alloy wheels.

Market Reception & Comparison

The Tata Tiago NRG 1.2 Revotron iCNG was generally well-received in the Indian market as an affordable and fuel-efficient crossover option. Critics praised its rugged styling and the benefits of the iCNG technology. However, some reviewers noted the engine’s limited power output, particularly when running on CNG. Compared to other Tiago variants, the NRG offered a more distinctive appearance and a slightly higher level of equipment. Compared to the petrol-only versions, the iCNG model prioritized fuel economy over outright performance. The Tiago NRG competed with other entry-level hatchbacks and crossovers in the Indian market, such as the Maruti Suzuki Celerio and Hyundai Grand i10.
