[OMatthew]

2009 Buick Excelle models may comply with either China IV or China III emission standards. You can check the environmental label located at the top right corner of the windshield, which indicates the vehicle's specific emission standard. This car is a classic family sedan. The Buick Excelle is a compact sedan under the Buick brand. There was no 2009 model year for the Excelle, with production years being 2008 and 2011 instead. The 2008 Buick Excelle was equipped with two engine options: a 1.6L naturally aspirated engine and a 1.8L naturally aspirated engine. For the 2011 model year, Buick discontinued the 1.8L engine variant, making the 1.6L naturally aspirated engine the sole powertrain option for the Excelle.
