A guy from Kazakhstan, who has Mk5 R32 HGP as well as Mitsu EvoVIII MR and Subaru Impreza STi PPP said the following:
R32 - 440ps, 585Nm, DSG.
0-62mph: 4.5 sek (lower than promised, probably due to lower quality petrol used), max achieved - 300kmh.
For the quartermile the car is not so good, because of the DSG. Evo with its carbon clutch takes the lead of approx 30 meters, Golf catches up in second gear, passes, and comes first to the finish line.
The car is quite ok in turns.
It starts to get unsettled after 260kmh because of the aerodynamics. After 1.5 years of active (sometimes brutal) driving nothing broke down. The only problem is that cooling system is insufficient in hot weather. On the other hand, he had to constantly change clutch and gearbox on Mitsu and Subaru, and on Subaru he had to change the engine as well.
Petrol consumption: 11 - 18 litres in city, 9-16 litres on highway.
