The Tata Sierra marks the return of one of Tata Motors’ most recognizable nameplates. The latest-generation Sierra is available with multiple powertrain options, including a 1.5-litre diesel engine. Our review focuses exclusively on the diesel model and examines its performance, comfort, features, and driving characteristics.
The Tata Sierra diesel is powered by a 1.5-litre four-cylinder diesel engine. The engine produces 118 hp and delivers 260 Nm of torque with the manual transmission. Automatic variants generate 280 Nm of torque and are paired with a 6-speed torque-converter automatic gearbox.
Tata Motors has updated the diesel engine with a revised state of tune and hardware improvements, including low-friction piston rings. These changes are aimed at improving efficiency and drivability.
The diesel engine delivers power in a linear manner rather than providing a sudden surge of torque. This characteristic makes acceleration predictable and suitable for everyday driving conditions. The automatic transmission is calibrated to keep the engine operating within its optimal power band, supporting smooth performance during city and highway use.
One of the key strengths of the Tata Sierra diesel is its suitability for highway journeys. The engine’s long-legged nature allows it to maintain cruising speeds comfortably over extended distances. Autocar India’s road test noted that the diesel powertrain is particularly well suited for frequent highway driving.
The SUV offers a commanding driving position and a spacious cabin layout. These characteristics contribute to occupant comfort during longer trips. The diesel automatic transmission further supports relaxed driving by delivering smooth gear changes without requiring constant driver input.
The Sierra has been engineered with a focus on ride comfort and stability. Higher variants feature Frequency Dependent Dampers (FDD), which help the suspension adapt to varying road conditions. The SUV remains composed over uneven surfaces and absorbs large potholes and road imperfections effectively.
The vehicle also offers 205 mm of ground clearance, helping it manage rough roads and light off-road conditions. Body roll remains controlled during cornering, while steering response is predictable and easy to manage in daily driving situations.
The combination of suspension tuning, ride height, and chassis setup contributes to overall passenger comfort across different road environments.
Fuel efficiency remains an important consideration for diesel SUV buyers. In Autocar India’s real-world fuel economy testing, the Tata Sierra diesel automatic returned 11.53 kmpl in city conditions and 14.56 kmpl on highways, resulting in an average of 13.05 kmpl. Actual mileage may vary depending on driving style, traffic conditions, and vehicle load.
