The data indicates that all Peugeot 206 (1998-10) 5DR Station Wagon 2.0 HDI 90 XSI AC models analyzed are equipped with a 2.0 HDI diesel engine, as evidenced by the 100% attribution of diesel fuel and the sole focus on engine capacity for 1997. This suggests a consistent use of diesel engines across the sample, highlighting the model's reliance on diesel for this particular variant. Notably, there is no variation in engine capacity data available, indicating that the 2.0 HDI diesel engine was the standard and perhaps only option for this model in the data sample.
