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 TataEngine
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 Tata sumo, safari and winger(VanEvolution
First Generation
At the time of launch (1991) the car came with a naturally aspirated (colloquially NA) ''483 DL engine'' mated with 5 speed gearbox, with power delivery to the rear wheels. Visually identical to the telcoline pickup from front, the rear portion was completely new design with large fixed alpine windows and entry through front collapsible passenger seat. The rear bumper had plastic shrouds on either end and bevelled lamps for illuminating the license plate located at central recess. The car had body mounted tricolor tail lamp (clear lens-orange-red), the headlamps came with black bezels, with amber lens turn indicators. The grill had a cheese grater appearance with the circular insignia flanked with two chrome bars. The "Tata sierra" badge (Tata written atop sierra) adorned the front quarter panel on either side with a single Tata logo placed on the rear door, the wheel arches were very thin and installed along the contour of arches. The spare wheel was externally mounted on the rear door and it came with fabric cover having stylised version of Tata sierra written over it.Second Generation
As the emission norms became further restricted and customers expected more power, TATA launched a turbocharged version in July–August 1997. The car had the 2.0 litre diesel engine as used earlier, to which a turbocharger (single stage) was added hence the name 483 DLTC ; the new engine was rated Euro 2 and had a maximum output of 87 horsepower. There was marked visual change on the outside with new bonnet that was extended further downward above the grill, the grill too was revised with appearance a venetian blind and at centre it had just the circular insignia (no chrome bars as earlier). The headlamps were revised too, the bezels were gone and now it became larger and visually more continuous with the indicators. At rear too there were major revisions, and the car got heated wind shields, tail lamps now become two tone unit (red-clear lens), the rear bumper became a completely wrapped around unit(metal)reaching the rear wheel arches, the now sported additional tail lamp bars, and the registration plate was illuminated by a single bar at the top. The wheel arches were revised too and now became more prominent and large. Logos were revised too, with just "sierra" written right next to the body mounted amber indicator on either side. Internally, the power window motor was changed and the new motor was directly linked instead of being linked via actuating cable. The wheel caps were revised, so were the optional alloys. The steering became a 4 spoke unit, unlike the previous 2 spoke one. The car was received well by the media and saw increased demand globally. The seats were provided by Harita Grammar Ltd. and later by Tata Johnson Ltd.In other countries
In Europe (especially in Spain, France, Germany and Italy), the Sierra was imported from 1994 under the name ''Tata Sport'' or ''Tata Telcosport'') in a single version with the 2.0L diesel engine Euro 2 in the rear wheel drive variant, while the 4x4 will be added in April 1998 proposed with the 2.0L turbodiesel. With the introduction of turbodiesel engine the name was changed in ''Tata Grand Telcosport'' in more market like Spain. In Italy the Sierra was sold as a ''Tata Sport'' in two versions: base and ''Orciari'', 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.Tata Sierra EV Concept (2020)
