The document analyzes the technology status of China's passenger car fleet in 2010 and provides international comparisons. It finds that the average engine size of China's fleet was 1.7L, smaller than the US and EU fleets. The power-to-weight ratio and fuel efficiency of China's fleet also lagged behind international levels. However, Chinese automakers have been adopting technologies like turbocharging, gasoline direct injection, and more efficient transmissions to close the gap in recent years.
