The Tata Altroz 1.2L iCNG is a compact hatchback manufactured by the Indian automaker Tata Motors. Introduced in May 2023, this variant expands the Altroz lineup with a factory-fitted Compressed Natural Gas (CNG) option, catering to the growing demand for alternative fuel vehicles in India. While the Altroz itself isn’t officially sold in the United States, understanding its specifications provides insight into the evolving automotive landscape in emerging markets and the increasing focus on fuel efficiency and reduced emissions globally. The Altroz competes in the subcompact hatchback segment, similar to vehicles like the Honda Fit or Toyota Yaris, though positioned as a more affordable option in its target market.
The Tata Altroz 1.2L iCNG: A Detailed Overview
The Altroz was designed to be a modern and feature-rich hatchback, aiming to disrupt the established players in the Indian market. The introduction of the iCNG variant further enhances its appeal by offering a more economical and environmentally friendly powertrain option. The Altroz iCNG is particularly relevant in India due to the widespread availability of CNG infrastructure and government incentives promoting alternative fuels. It represents Tata Motors’ commitment to providing sustainable mobility solutions.
Engine & Performance
The Altroz 1.2L iCNG is powered by a 1.2-liter, three-cylinder, naturally aspirated gasoline engine that has been adapted for dual-fuel operation – gasoline and Compressed Natural Gas. When running on gasoline, the engine produces 88 horsepower at 6000 rpm and 115 Nm of torque (approximately 84.82 lb-ft) at 3250 rpm. The power output drops slightly to 73 horsepower at 6000 rpm when operating on CNG, with torque reduced to 103 Nm (approximately 76 lb-ft) at 3500 rpm. This reduction in power is typical for CNG conversions, as CNG has a lower energy density than gasoline. The engine utilizes a multi-port fuel injection system and features a Start & Stop system to further improve fuel economy. The engine’s power per liter is 73.4 hp/l on gasoline and 60.9 hp/l on CNG. The powertrain is coupled with a five-speed manual transmission, delivering power to the front wheels.
Design & Features
The Tata Altroz 1.2L iCNG maintains the stylish and contemporary design language of the standard Altroz. It’s a five-door hatchback with a relatively spacious interior for its class, comfortably seating five passengers. The exterior design is characterized by its sharp lines, sculpted body panels, and distinctive front grille. While specific trim levels vary, the Altroz generally offers features such as air conditioning, power windows, and a touchscreen infotainment system. Safety features include Anti-lock Braking System (ABS) as standard. The iCNG variant incorporates a dedicated CNG tank, strategically positioned to minimize intrusion into the passenger or cargo space. Trunk space is reduced to 210 liters (7.42 cubic feet) to accommodate the CNG tank, but remains usable for everyday needs. The vehicle’s dimensions are 3990 mm in length (157.09 inches), 1755 mm in width (69.09 inches), and 1523 mm in height (59.96 inches), with a wheelbase of 2501 mm (98.46 inches) and a ground clearance of 165 mm (6.5 inches).
