Aggressive engine downsizing continues to be an effective method, pursued by numerous automakers, to reduce emissions and improve fuel efficiency. Recently, General Motors of India joined the downsizing bandwagon with the launch of its 1.2-liter Smart-Tech engine. The pint-sized mill was developed at GM's Technical Center-India and will be manufactured at the automaker's engine plant in Talegaon.

The Smart-Tech engine features a lightweight aluminum alloy block and cylinder head. The pistons incorporate low friction rings to maximize fuel economy and the engine's twin cam design combines direct valve actuation with an elongated intake manifold to boost low-end torque and improve efficiency.

The 1.2-liter Smart-Tech mill could eventually weasle its way between the fenders of Indian-market versions of the Chevrolet Spark, Beat, Captiva, Optra, Cruze, Aveo, Aveo U-VA and Tavera.

General Motors India Introduces Locally Developed Smart-Tech Engine

Will Power New Products Built and Sold Domestically


New Delhi: General Motors India launched its new locally developed, state-of-the-art Smart-Tech engine today at a ceremony presided over by General Motors International Operations President Tim Lee.

According to Lee, "India is a key market for General Motors. We are focused on leveraging our unmatched global resources as well as our growing local capability to develop segment-leading vehicles and powertrains in India for India."

The 1.2-litre Smart-Tech engine was created by the GM Technical Centre-India in Bangalore in cooperation with GM's new engine plant in Talegaon. It will be produced at the Talegaon facility for a range of new models offered by GM in India.

"Our new engine is the result of an enormous R&D effort and thousands of hours of design, validation and testing. It incorporates engineering changes which optimize engine performance for Indian conditions through innovative design techniques," said Karl Slym, President and Managing Director of General Motors India. "The engine demonstrates the true potential of GM's engineering and manufacturing capability across India."

The Smart-Tech engine features aluminum cylinder heads, deep skirt cylinder block and lightweight pistons with low tension rings, which decreases weight and maximizes fuel economy. The engine also features a DOHC valvetrain with direct acting valve actuation to further improve the efficiency, a long runner plastic intake manifold for good low-end torque and lightweight counterbalanced crank shaft for great NVH.

The engine has a maintenance-free inverted tooth timing chain drive system. The chain links engage at a lower impact speed, which decreases the noise generated for quiet operation. The 1.2 litre Smart-Tech engine delivers uncompromised power and durability in a small package size. Extensive testing and validation were carried out in India to guarantee top-of-the-line performance in all vehicle models that will adopt the engine.

About General Motors India: General Motors has completed 14 years of operation in India. Chevrolet, which was introduced in 2003, is one of the fastest-growing vehicle brands in India. GM India's state-of-the-art manufacturing facilities in Halol, Gujarat, and Talegaon, Maharashtra, build the Chevrolet Captiva, Chevrolet Optra, Chevrolet Cruze, Chevrolet Aveo, Chevrolet Aveo U-VA, Chevrolet Spark, Chevrolet Beat and Chevrolet Tavera for sale across India.
