Tata Tiago NRG (facelift ) 1.2 Revotron (86 Hp) Automatic

The Tata Tiago NRG (facelift 2020) 1.2 Revotron (86 Hp) Automatic is a crossover variant of the popular Tata Tiago, introduced in 2020 as part of a mid-life refresh for the model. Positioned as a more rugged and visually distinct version of the standard Tiago, the NRG aimed to appeal to buyers seeking a vehicle with a slightly more adventurous aesthetic and enhanced ground clearance. This particular configuration, featuring the 1.2-liter Revotron engine paired with an automatic transmission, served as an entry-level automatic option within the Tiago NRG lineup, offering convenience and ease of driving at a competitive price point. It was built on the Tata Motors’ X0 platform.

Powertrain & Engine Architecture

The heart of the Tiago NRG 1.2 Revotron Automatic is the Revotron 1.2-liter inline-three cylinder naturally aspirated gasoline engine. This engine, designated with the internal code Revotron, displaces 1199 cm³ (73.17 cubic inches) and produces a maximum power output of 86 hp at 6000 rpm, and 113 Nm (83.34 lb-ft) of torque at 3300 rpm. The engine utilizes a multi-port fuel injection system, a common setup for this class of vehicle, and features four valves per cylinder. The engine’s relatively small displacement and three-cylinder configuration contribute to its fuel efficiency, but also result in inherent vibrations which Tata Motors addressed through engine mounting and balancing techniques.

The automatic transmission paired with this engine is a 5-speed unit. While not known for particularly rapid shifts, it provides a comfortable and convenient driving experience, especially in urban traffic. The transmission is electronically controlled, optimizing gear selection based on throttle input and vehicle speed. The gear ratios are tuned for fuel economy and drivability rather than outright performance. First gear is relatively short for quick acceleration from a standstill, while higher gears are geared for efficient cruising. The transmission lacks a manual shift mode or sport setting.

Engine Specifications

The Revotron engine is a relatively simple design, prioritizing reliability and affordability. It features a timing chain rather than a belt, reducing maintenance requirements. The engine oil capacity is 3.5 liters (3.7 US quarts or 3.08 UK quarts), and the recommended oil specification is dependent on local market requirements. The cooling system capacity is 4 liters (4.23 US quarts or 3.52 UK quarts). A Start & Stop system is included as standard, further enhancing fuel efficiency by automatically shutting off the engine when the vehicle is stationary.

Driving Characteristics

The Tiago NRG 1.2 Revotron Automatic delivers a comfortable, if not particularly exhilarating, driving experience. The 86 hp output and automatic transmission combination result in modest acceleration. The vehicle feels adequate for city driving and highway merging, but struggles when fully loaded or attempting quick overtaking maneuvers. The automatic transmission contributes to a smooth driving experience, but can sometimes feel hesitant when downshifting. The power-to-weight ratio of 86.9 hp per tonne and torque-to-weight ratio of 114.1 Nm per tonne reflect the vehicle’s modest performance capabilities.

Compared to the manual transmission version of the same engine, the automatic variant typically exhibits slightly reduced fuel economy due to the inherent losses within the torque converter. However, the convenience of the automatic transmission often outweighs this slight efficiency penalty for many drivers. Compared to higher-spec Tiago models with more powerful engines, the NRG 1.2 Automatic offers a more affordable entry point but sacrifices performance. The suspension is tuned for comfort, absorbing bumps and imperfections in the road surface effectively.

Equipment & Trim Levels

The Tiago NRG (facelift 2020) 1.2 Revotron Automatic came equipped with a range of standard features. These typically included air conditioning, power windows, central locking, and a basic audio system with Bluetooth connectivity. Safety features such as ABS (Anti-lock Braking System) were standard. The NRG trim level also added unique exterior styling elements, such as black plastic cladding around the wheel arches and rocker panels, roof rails, and a distinctive front grille. Interior features included sporty seat upholstery and a unique dashboard design. Optional extras available for this trim could include alloy wheels, a touchscreen infotainment system, and rear parking sensors.

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 and decent handling characteristics. The rear suspension employs a torsion beam axle, a cost-effective and space-efficient solution. The front brakes are disc brakes, offering adequate stopping power, while the rear brakes are drum brakes, a common feature in this segment to reduce costs. The steering system is an electric power steering rack and pinion, providing light and easy steering feel. The vehicle is equipped with 14 or 15-inch wheels, typically fitted with 175/65 R14 or 175/60 R15 tires.

Market Reception & Comparison

The Tata Tiago NRG 1.2 Revotron Automatic was generally well-received in the Indian market as an affordable and practical crossover option. Critics praised its rugged styling, comfortable ride, and convenient automatic transmission. However, some reviewers noted the engine’s lack of outright power and the transmission’s occasional hesitation. Compared to other automatic hatchbacks and crossovers in the same price range, the Tiago NRG offered a compelling value proposition, particularly for buyers prioritizing affordability and fuel efficiency. Its BS6 emission standard compliance was also a positive point, reflecting Tata Motors’ commitment to environmental responsibility.

In terms of reliability, the Revotron engine has proven to be generally dependable, although some owners have reported minor issues with the fuel injection system and cooling system. Regular maintenance, including timely oil changes and coolant flushes, is crucial for ensuring long-term reliability.
