Tata Indigo

Facelifted Indigo SW sedan (Marina)

The first generation Tata Indigo was launched in 2002, and was largely based on the Indica. The two cars shared a majority of their parts. The Indigo had a greater wheelbase than the Indica, to accommodate the more acute-angled C-pillar and the trunk. The front bumper had housings for fog lamps, a feature which the Indica lacked at the time. While the Indica had a 1.4 L naturally aspired 55 hp (41 kW) diesel engine, the Indigo featured its turbocharged variant, which produced 68 hp (51 kW). The car was also offered with a 1.2 L 68 hp (51 kW) 4-cylinder MPFI petrol engine. The interior of the Indigo featured a few exclusives over the Indica, such as HVAC and fabric upholstery on all variants, and power windows for all doors on the top model. The steeper angle of the C-pillars meant that the Indigo lacked a rear windshield wiper. A minor design refresh in 2004 introduced a new 1.4 L turbocharged diesel engine.

In 2006, Tata Motors introduced the first major design update for the Indigo, with new body panels, a redesigned front grille housing double-barreled headlamps, triangular front fog-lamps, a multi-reflector tail-lamp cluster with dual brake lamps; a newer 3-spoke steering wheel, refreshed dual-tone fabric interiors, and an audio system with a CD player. Under the hood, it featured a new 1.4 L Dicor turbocharged common rail diesel engine, which produced 70 hp (52 kW) and complied with the Bharat Stage III emission norms.

The 2006 Tata Indigo formed the base platform for three other cars, the Indigo Marina station-wagon, the Indigo XL sedan, and the Indigo CS compact-sedan.

Launched in 2007, the Indigo XL was a variant of the 2006 Indigo, with its wheelbase increased by 200 mm, and a few upmarket features. The added wheelbase translated into increased legroom in the second seating row and a bigger trunk. Tata Motors positioned it as a premium product and equipped it with a few upmarket features such as optional leather upholstery, rear air-conditioner vents, a rear center arm-rest with cup-holders, and a new 16-valve MPFI petrol engine option, with DOHC and a power output of 101 hp (75 kW). It retained the 1.4 L Dicor engine from the Indigo.[2]

In 2009, with the introduction of the Indigo Manza based on its newer X1 platform, Tata Motors pulled the Indigo XL from consumer sales, and relegated it only to fleet sales as a taxi. The 2009 Indigo XL retained most of its feature-set from the 2007 original, with the exception of lack of leather upholstery and factory-fitted audio system. The car was offered in three engine variants, beginning with the 16-valve MPFI petrol engine carried over from the original, with a newer Bharat Stage IV-compliant catalytic converter, a dual-fuel CNG variant, which can switch on-the-fly between petrol and CNG, with a factory-fitted CNG kit; and the 1.4 L CR4 turbocharged common-rail diesel engine, also Bharat Stage-IV compliant, with a power output of 70 hp (52 kW).

2014 Tata Indigo CS

The Indigo ECS (compact-sedan) was launched in 2008, as a crossover between a hatchback and a sedan, while technically being referred to as the latter. It was originally designed to appeal to buyers who sought an inexpensive "3-box" car at the price of a hatchback. At launch, the Indigo CS was the shortest sedan in the world, with a length of 3,998 mm. The car's length allowed Tata Motors to avail excise-duty incentives targeted at cars with under 4 meters of length. The Indigo CS retained most of the feature-set of the 2007 Indigo. The car was launched with the 1.4 L TDI turbocharged diesel engine, and the 1.2 L 8-valve, 4-cylinder petrol engine carried over from the Indica Xeta. Both these engines complied with Bharat Stage-III emission norms.

In 2010, Tata Motors introduced the first design update to the Indigo CS, in the form of the company's new 1.4 L CR4 turbocharged common-rail diesel engine, rechristening the car as Indigo eCS. The 1.4 L CR4 engine complies with the Bharat Stage-IV norms. Variants of the car, with the Bharat Stage-III compliant TDI engine continued to be sold till 2012. The 1.2 L SOHC petrol engine was carried over, with an upgraded Bharat Stage-IV compliant catalytic converter.

In 2012, Tata Motors introduced a high-end version of the car, the Indigo eCS VX, featuring anti-lock braking system (ABS) with electric brake-force distribution (EBD), electrically-adjustable outside rear-view mirrors (E-ORVMs), side repeaters mounted on the ORVMs, and 14-inch alloy wheels.

In 2013, the company introduced a more pronounced design refresh of the car, featuring redesigned body panels, chrome-inserts on the front-grille, trunk-lid, and front fog-lamp accents; smoked double-barreled headlamp housing, "Sahara Beige" fabric upholstery, dual-tone interiors with jet-black and beige tones, a newer 4-spoke steering wheel, and a 2-DIN audio system head-unit, with Bluetooth pairing for smartphones, for hands-free voice calls. The company also introduced variants with factory-fitted CNG kits, called the Indigo eCS e-Max. The car was discontinued in April 2016.[3]
