Daewoo S-TEC Engine - S-TEC

S-TEC

The first model was 0.8 L (796 cc) SOHC inline-triple engine based on the powerplant of the Suzuki Alto. It was used in Daewoo Tico and later the Daewoo Matiz.

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 pollution. 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. They are used in Chevrolet Matiz (model M200).
