The Tata Sierra, was a three-door sport utility vehicle produced by the Indian carmaker Tata Motors It was based on the Tata Telcoline. In the export market, the Sierra was sold as Tata Sport, Tata Telcosport and Tata Grand Telcosport, Tata Gurkha. History The Tata Sierra was launched in 1991 and is the first off-road Sport Utility vehicle produced by the Indian company; and was based on the Tata Telcoline (pick-up originally launched in 1988 from which it takes the mechanical parts, the front facia, and the internal dashboard.) The differences are in the shortened wheelbase at 2.40 meters (compared to the single-cab Telcoline). The Sierra was also one of the first cars for private transport in India and, being built on the Tata ''X2 platform" with side members and crossbars, could be used on every road surface, especially the uneven ones being proposed both rear-wheel drive and four-wheel drive. Compared to the Telcoline, soundproofing has been improved, making the interior more comfortable. 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. Engine The engine was the same as the Telcoline: the naturally aspirated, 2.0-liter 483 DL(DL stands for Diesel) four-cylinder diesel engine developed by Tata Motors in India. It has two valves per cylinder and indirect injection with pre-chamber and develops 63 horsepower. The gearbox is a G76 5-speed manual. The later Turbo model was powered by a 483DLTC( DLTC stands for Diesel Turbocharged) inline-four engine. Later this engine was used on the Tata sumo, safari, and winger(Van). The cockpit was available only for four seats. The Sierra was also the first car produced in India with electric windows( This is false information. The Standard 2000 was the first car in India with power windows), air conditioning, an adjustable steering wheel, tachometer. First Generation (1991) 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.
