About Chevrolet Aveo T250

GM introduced a revised sedan at Auto Shanghai 2005, designed in cooperation with PATAC. Bearing the internal code T250 and sold in South Korea as the "Daewoo Gentra", the revision comprised primarily interior and exterior styling changes, a new interior instrument panel and minor equipment changes, including increased sound deadening. Incorporation of the radio antenna into the rear glass and extensive wind tunnel testing helped reduce the coefficient of drag from 0.348 to 0.326.

A restyled hatchback with the sedan's updated instrument panel was presented as the Chevrolet Aveo during the Frankfurt Motor Show 2007, to be marketed in Europe and North America. The Korean market received its own distinct restyle of the hatchback, the Gentra X.

Later iterations, including the Kalos, Aveo, Barina and Gentra sedans, the Gentra X hatchback and the 2007 "Frankfurt Show" hatchbacks were styled in-house and with the assistance of PATAC, and depart notably from the original Giugiaro exterior and interior styling designs.

With launch of the Gentra X in South Korea, GMDAT had replaced engines of T250. 1.2 L S-TEC II inline-four engine was updated with features such as dual overhead camshaft (DOHC) and timing chain (older version has timing belt) system. 1.6 L E-TEC II engine had replaced with ECOTEC (GEN-III) engine with new features such as variable valve timing mechanism.

Design Development of Chevrolet Aveo T200

Daewoo's now disbanded Worthing Technical Centre in the UK conducted the initial research and platform engineering, with Daewoo's main Technical Center in Bupyong, Incheon, South Korea completing the majority of the later development programme. Daewoo engineers refined the chassis in Britain, on the proving ground at Motor Industry Research Association near Nuneaton, UK. Long-term testing covered nearly 2.2 million kilometers (1.4 million miles) with further testing outside South Korea on test sites in Arjeplog, Sweden; Granada and El Vendrell, Spain; Kapuskasing, Canada and Beijing, China. According to an April, 2003 GMDAT press release, Daewoo built 119 prototypes during the Kalos's design and development, crashing 31 for research and data-gathering purposes, and manufacturing 39 pilot production vehicles to verify standards and quality.

The body's sheet metal panel gaps were kept to 3 mm (0.1 in) and all but the roof panel were galvanized steel. 46% of the Kalos' underlying structural components were produced with high-strength steel, with tailor-welded blanks used in the production of the vehicle to put strength where needed while saving weight. The front suspension used MacPherson struts with offset coil springs and a stabilizer bar, while the rear featured a semi-independent torsion beam axle.

The body featured a drag coefficient of 0.35, with a frontal area of 2.16 m2 (23.3 sq ft) giving aerodynamic resistance of 00.74 m2 (8.0 sq ft). All Kalos iterations featured high H-point seating within a relatively narrow, short and high-roofed body that combined a long wheelbase with short front (81 cm/32 in) and rear (49 cm/19 in, hatchback) overhangs to maximize the outward visibility, interior space and maneuverability relative to the vehicle's footprint. Rear seat H-points are higher in all body types, giving the car theatre seating.

About Chevrolet Aveo

The first generation of Chevrolet Aveo began with launching Model T200, a subcompact automobile which has manufactured and marketed since 2002 by GM Daewoo, the South Korean subsidiary of General Motors. The model was marketed prominently under the nameplate Aveo. The model received the T200 internal codes, used first by Daewoo, and then, by GM Daewoo during the car's development. The T250 code was designated for the facelifted models.

Designed, engineered and originally marketed by GM Daewoo, the Aveo succeeded the Daewoo Lanos and was marketed worldwide in 120 countries under five brands: Chevrolet, Daewoo, Holden, Pontiac, and Suzuki, being originally called Daewoo Kalos in its home country market South Korea, before being rebranded Daewoo Gentra. In other markets, the first generation model was marketed as the Holden Barina in Australia and Asia, Pontiac G3 in the United States and later Canada, previously in Canada as the Pontiac Wave and currently in Canada as the Suzuki Swift⁺. The successor of T200, the Chevrolet Aveo T300 will be released in 2011.
