The QQ remained at the centre of an industrial copyright and intellectual rights controversy, as General Motors claimed the QQ was highly similar to the Chevrolet Spark/Daewoo Matiz. GM executives demonstrated the extent of the design duplication, noting for example that the doors of the Chery QQ and the doors of the Chevrolet Spark are interchangeable without modification.
- GM China Group indicated the two vehicles "shared remarkably identical body structure, exterior design, interior design and key components."
- MotorAuthority.com and Car and Driver called the QQ a "carbon copy."
- The International Herald Tribune, in a 2005 article, referred to the QQ as a clone.
Looking at this controversy on a global stage, the Detroit News reported that "the dispute reflects the confusion, risks and ambitions in China's new auto industry, where global carmakers are battling pugnacious upstarts for a piece of what may become the world's largest auto market."
