The S-TEC, like many GM Daewoo engines, was never an all-original Korean engine from the ground up. The Matiz (aka "Spark") itself replaced the Daewoo Tico, a variant of the 1988 Suzuki Alto.
S-TEC is a low-displacement engine range codeveloped by Suzuki and Daewoo Motors for use in micro- and subcompact cars.
The first model was 0.8 L Straight-3 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 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 0.8/1.0 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).

Here's official engine data for new Chevrolet Matiz from www.gmeurope.com/geneva2005; fuel economy is 13% to 18% better comparing with older-generation engines!
EDIT: wrong mpg conversion; corrected!
Code:
Engine ====== new S-TEC =======
0.8L 3i 1.0L
Power, kW (hp) 38 (52) 49 (66)
@ rpm 6000 5400
Torque, Nm (lb.ft) 72 (53) 91 (67)
@ rpm 4600 4200
Comsumption,
L/100 km (mpg)
Urban 6.9 (34.1) 7.2 (32.7)
Extra-urban 4.2 (56.0) 4.6 (51.1)
Combined 5.2 (45.2) 5.7 (41.3)
I think it's reasonable to expect at least 10% improvement for the upper-range as well, considering the updated technology. |
