[2] The body of the Sierra is three-door, the total length of the body is 4.41 meters, rear-wheel drive or 4WD full-time part-time with grafting system electrically controlled up to 60  km/h, equipped with the gearbox on all ratios, self-locking rear differential and front hubs with manual locking/unlocking; the suspensions are the same as those of the Telcoline with an oscillating double trapezoidal front axle and a rear axle with a rigid bridge layout with five pulling arms and coil springs.

[citation needed] At the time of launch (1991) the car came with a naturally aspirated (colloquially NA) 483 DL engine mated with a 5-speed gearbox, with power delivery to the rear wheels.

The rear bumper had plastic shrouds on either end and beveled lamps for illuminating the license plate located at the central recess.

The car had body mounted tricolor tail lamp (clear lens-orange-red), and the headlamps came with black bezels, with amber lens turn indicators.

The spare wheel was externally mounted on the rear door and it came with a fabric cover having a stylized version of Tata Sierra written over it.

[citation needed] As the emission norms became further restricted and customers expected more power, TATA launched a turbocharged version in July–August 1997.

The seats were provided by Harita Grammar Ltd. and later by Tata Johnson Ltd.[citation needed] The third generation Sierra was unveiled on 18 January 2025.

In Italy the Sierra was sold as a Tata Sport in two versions: base and Orciari,[7] the latter exclusive for Italy was made by the Italian designer Orciari and featured an enriched endowment, two-tone bodywork, roof bars, and specific interior finishes.
