2017-2020 Tata Tigor 1.05d (70 Hp)

The Tata Tigor 1.05d (70 hp) was a subcompact sedan produced by the Indian manufacturer Tata Motors from March 2017 to January 2020. It represented the entry-level diesel variant within the Tigor model range, which itself was Tata’s attempt to compete in the increasingly popular sub-4 meter sedan segment in the Indian market. Positioned as an affordable and fuel-efficient option, the 1.05d aimed to attract buyers seeking a practical and economical daily driver. The Tigor, as a whole, was based on the Tata Tiago hatchback, sharing its platform and many components, but offering the added practicality of a sedan body style.

Powertrain & Engine Architecture

The heart of the Tigor 1.05d was the Revotorq 1.05-liter inline-three cylinder diesel engine, designated as the TDC4 engine family. This engine, with the code designation varying slightly depending on the specific production date, was a relatively simple and robust design intended for affordability and reliability. It featured a turbocharger with an intercooler to improve power output and efficiency. The engine utilized a diesel commonrail fuel injection system, delivering fuel directly into the cylinders at high pressure for optimized combustion. The valvetrain employed a Double Overhead Camshaft (DOHC) configuration with four valves per cylinder, contributing to improved breathing and power delivery. The engine produced 70 horsepower at 4000 rpm and 140 Nm (103.26 lb-ft) of torque between 1800-3000 rpm. The engine was transversely mounted at the front of the vehicle.

Transmission

The Tigor 1.05d was exclusively offered with a 5-speed manual transmission. An automatic transmission option was not available for this specific engine variant. The gearbox was chosen for its simplicity, durability, and cost-effectiveness, aligning with the overall positioning of the vehicle as an entry-level offering. The gear ratios were tuned to prioritize fuel efficiency and driveability in urban conditions, rather than outright performance.

Driving Characteristics

The driving experience in the Tigor 1.05d was characterized by its focus on fuel economy and ease of use. With 70 hp, acceleration was modest, and the vehicle was not designed for spirited driving. The turbocharger helped to mitigate some of the power deficit, providing a noticeable boost in torque at lower engine speeds. However, the engine could feel strained when fully loaded or attempting to overtake at highway speeds. The 5-speed manual transmission offered a reasonably smooth shifting experience, although the shift linkage wasn’t particularly precise. The gear ratios were spaced to keep the engine within its optimal torque band for everyday driving. Compared to higher-spec Tigor variants with larger engines, the 1.05d offered significantly less performance, but it also provided superior fuel efficiency.

Equipment & Trim Levels

The Tigor 1.05d typically came with a basic level of standard equipment, reflecting its entry-level status. Standard features generally included manual air conditioning, power steering (electric), front power windows, and basic instrumentation. Safety features typically included ABS (Anti-lock Braking System). Interior upholstery was usually cloth, with a simple dashboard layout. Optional extras, depending on the specific trim level (XE, XM, XZ), could include features like central locking, a basic audio system, rear power windows, and body-colored door handles and mirrors. Higher trim levels offered more comfort and convenience features, but the core focus remained on affordability.

Chassis & Braking

The Tigor 1.05d utilized a McPherson strut independent suspension system at the front, providing a reasonable level of ride comfort and handling. The rear suspension was a semi-independent coil spring setup, which was a cost-effective solution for the rear axle. The front brakes were disc brakes, offering better stopping power than drum brakes. However, the rear brakes were drum brakes, a common cost-saving measure in this segment. The steering system was a rack and pinion type with electric power steering, providing light and easy steering feel. Tire sizes varied depending on the trim level, with 155/80 R13 or 175/65 R14 being common options. Wheel rim sizes were correspondingly 4.5J x 13 or 5J x 14.

Market Reception & Comparison

The Tata Tigor 1.05d received mixed reviews from automotive critics. It was generally praised for its fuel efficiency, affordability, and compact size, making it well-suited for navigating congested city streets. However, it was often criticized for its lack of power, basic interior, and somewhat underwhelming driving dynamics. Compared to other diesel-powered subcompact sedans in the Indian market, such as the Maruti Suzuki Dzire and the Honda Amaze, the Tigor 1.05d offered a competitive price point but lagged behind in terms of refinement and performance. Fuel economy figures typically ranged from 24-27 kmpl (kilometers per liter), making it one of the more fuel-efficient options in its class. Reliability was generally considered to be average, with some reports of minor issues with the fuel injection system and turbocharger.

Technical Specifications

Legacy

The Tata Tigor 1.05d, while not a standout performer, played a significant role in establishing Tata Motors as a competitive player in the Indian subcompact sedan market. The Revotorq diesel engine, despite its relatively simple design, proved to be reasonably durable and reliable. In the used car market, the Tigor 1.05d remains an affordable and practical option for buyers seeking a fuel-efficient and low-maintenance vehicle. However, potential buyers should be aware of the engine’s limited power output and the basic level of equipment. Parts availability is generally good, and maintenance costs are relatively low, making it a sensible choice for budget-conscious consumers. The Tigor 1.05d represents a specific point in Tata’s evolution, showcasing their commitment to providing accessible and economical transportation solutions.
