I recognise that RR graph
Although what he is not telling you is that the car comes as std with a K04 Twin scrol Borg Warner Turbo whereas the Skoda will probably have a K03. Max headroom on that is around the 310hp mark with the same torque. The 30th Edition GTI, Audi S3 and Leon Cupra with the K04 have max headroom of something a little shy of 400hp on std internals. The Audi can get to around 450PS as it has a closed deck, but the weight and drivetrain losses (which are not bad at around 22% for the quattro) hold it back a little.
And the cost in old world money? Realising this is in Rip Off Britain, around £2000 and you have at full boost by 2.7k, with a minimum of 300 ft/lbs from 2k to the redline at 7.1k.
(Apologies for not converting from hp to kw, not sure of the math, sure that scathing will correct me )
