History

[edit]

The Sumo was launched in 1994 as a ten-seater rear-wheel-driveSUVprimarily designed for military use and off-road transport.[1]It saw great sales success, and more than 100,000 Sumo vehicles were sold prior to 1997.[2]

Rear of the Tata Sumo

The Sumo was based on theTelcoline'sTata X2body-on-frameplatform[3]with a redesigned and strengthened rear axle to adapt it to off-road use with part-time all-wheel drive (rear-wheel drive with the option of traction in off-road situations only) with grafting system an electric control up to 60 km/h, self-locking rear differential and manual block front hubs, then eliminated in favor of the fully automatic solution. The front suspension is a double swinging trapezium and torsion bar, while a salisbury type beam rear axles with parabolic leaf springs and antiroll bar has been adopted at the rear. The front brakes are a ventilated disc combined to the rear which is a self-adjusting drum.

In the Indian market the rear-wheel drive version was sold to the civilian market, the four-wheel drive was sold to fleets and the Indian army. In the export market the 4WD version was regularly sold alongside the 2WD.

Prior to the Sumo, the Indian market had stagnated, where the most modern vehicles in the same class were fromMahindra and Mahindra,primarily derived from the originalWillys Jeepmodels. Upon release, Tata Sumo quickly captured a major segment of the utility automobile market in India.

The Sumo name comes fromSumant Moolgaokar,a former MD of Tata Motors.[4]

The engine was the same as the Telcoline: the 2.0-liter (1,948 cc) four-cylinder dieselPeugeot XD88naturally aspirated manufactured under license by Tata Motors in India with two valves per cylinder and indirect injection with pre-chamber and 63 horsepower. The gearbox is a G76 5-speed manual.

In 1996 the Sumo range was updated with the new more refined "Deluxe" version. In 1998 Tata introduced turbocharged version of thePeugeot XD882,0 litre diesel engine for the export market, the new engine is homologated Euro 2 and has an output of 92 horsepower.

In 2001 the Sumo Deluxe Turbo with 2.0 TDi engine was introduced in India.[5]

Tata Sumo Spacio (2000-2011)

[edit]

An updated version, called Tata Sumo Spacio was launched in 2000.[6]The Sumo Spacio introduced a new 2956 cc direct injection naturally aspirated diesel engine (known as Tata4SPwith 65 horsepower) which was sourced from the light commercial vehicleTata 407.The major changes to Sumo were in the powertrain. Riding on a longer wheelbase as compared to earlier version, the Spacio used a different transmission, rear axle and tyres specifically to get better fuel economy. Apart from being a 'No-Frills' version, the prominent visual difference between Sumo Spacio and the old Sumo was the presence of round headlamps instead of the rectangular ones.

A soft top version of the Spacio called theSpacio STwas also introduced for rural markets.[7]The Spacio ST was also available in 4WD version.

With the introduction of the Sumo Spacio, the previous Sumo remained in production, with higher list prices and 2.0-liter aspirated and turbo engines (since 2001). In fact, Spacio represented a cheaper version of the classic Sumo.

In early 2007 Tata Motors launched the Spacio Gold Plus.[8]This version received the 3,0 turbocharged engine of the 4SP family and offered increased power of 70 horsepower (at 3,000 rpm) and 223 Nm of torque (at 2,200 rpm).
