China starts selling the new Buick Excelle GT sedan on June 23 following its official unveileing. Engines include the 181bhp 1.6 turbo.

Buick has announced that the Excelle GT sedan will start selling in China on June 23. It was spied completely undisguised just less than two months ago. Marketing positioning places it as a high-end mid-size car with very high build, comfort and engine quality. Styled along the lines of the Buick LaCrosse sedan, the Excelle GT is based on the all-new Opel/ Vauxhall Astra platform.

It features engines such as the 1.8-litre Eco Smart with 103 kW (138 bhp / 140 PS) and 175Nm of torque, and the powerful 1.6-litre turbo. The latter makes 135 kW (181 bhp / 184 PS) and 235Nm of maximum torque. An extra 31 Nm of boost is available for five seconds during overtaking.

The exterior is characterised by Buick's waterfall front grille, distinctive headlights, porthole vents on the bonnet and eye-catching taillights. The interior shows very strong links with the Astra and features the Angie Star OnStar full-time online assistant. Roominess comes courtesy of a 2,685mm (105.7 inches) wheelbase.

While China is welcoming this version, the North American Excelle GT will probably make its debut in 2011 as a 2012 model.
