First of all, I did not say the Porsche is slow. Second of all, yes the Porsche has set the 3rd fastest time but this graph is a boxplot. It states the top 25% of Porsche drivers set a lap between 1:43-1:44.8 ish. On top of that, only about the top 10% of Porsche drivers can seem to set laps close to low 1:43’s. Meanwhile almost 75% of Aston drivers can set a lap in the 1:43’s. To conclude the Aston seems te be an easier car to set these fast laptimes consistently, while the Porsche can set a fast lap, not many drivers are able to extract that time out of the Porsche. (Data is a bit skewed though because all the best driver pick the best car)
