S-TEC or M-TEC is a low-displacement engine range co-developed by Suzuki and Daewoo Motors for use in micro- and subcompact cars.
The first model was 0.8 L (796 cc) SOHC inline-triple engine based on the powerplant of the Suzuki Alto.
In 2002, the range was extended to 1.0 L and 1.2 L (1150 cc) straight-4 engines and updated with EGR valve to reduce emission. A new engine plant for the updated model T4 was built. The 1.0 version is used in Chevrolet Matiz and the 1.2 in the European Chevrolet Kalos.
In 2004 the 0.8 and 1.0 engines were updated again. New intake and exhaust systems, along with low-friction aluminum cam followers with rollers were added, resulting in better economy.
Applications:
For 2008, a new 1.2 L (1206 cc) version dubbed S-TEC II is introduced with the new Chevrolet Aveo hatchback; new features include chain-driven 16-valve DOHC valvetrain and variable intake geometry. The 1.0 L version has been introduced with the 2010 Chevrolet Spark. A 1.2 L LPG/gasoline version was developed exclusively for the India market; called SMARTECH II and used in the 2010 Chevrolet Beat. Introduced in 2013, the 1.2 L version is available in the United States version of the Chevrolet Spark.
