Its not real world though is it ?...big cc cars are fast on an " endless" straight. But add in traffic, stops etc...still few big cars which can make progress like a bike can. Plus, dont even want to think what the mpg of the merc is at this speed !
Have encountered very few cars on normal roads which keep up with a large cc bike , as much due to traffic limitations as anything.
Have experienced a M5 on the A2 which was very quick up to 150, but that was an empty 3 lane motorway.
Only time on my fazer I encountered a ferrari on a twisty road , he couldnt keep up.Probably didnt want to risk his pride and joy maybe ?? But ferraris are big wide cars on B roads.
You have to be avery good driver to pilot these beasts on a twisty road.
Best cars IMO for the real world are yer hot hatches or suburus simply cos of their nimbleness. A 3.2 litre audi A3 is a potent car for sure. Let alone an Rs4 or 8.
Must still be very frustrating for most " fast " car owners as where can they use them for most of the time ? Pose is probably more the norm than real action....
