So, here is a bit of an explanation of why I ended up with the Polo GTI............
The graph below shows my acceleration curve in comparison with four other performance cars. The lower the line on the graph the faster it is.
As you can see it isn't until 130-140kph that even the 395bhp Golf would get to the same speed as my Polo GTI. However, because I would have accelerated faster up to that point my car would be further ahead of the Golf at the point they are at the same speed. The Focus doesn't even get to the same speed as my Polo until 160kph (100mph).
