It isn't under powered, everyone thinks "pfft 160 brake that's nothing" my Hillman Imp has 40 brake and it goes alright for what it is, i reckon it would out class most modern cars with 1.0L engines, possibly 1.2's because it's so light. 160 brake is far from under powered, think of it from when the engine came out, that was pretty damn powerful. Also, think about it, the Cologne V6 has one cam and 12 valves. The Scorpio V6 has twice as many valves and 4 cams and it's only achieved 40 brake more and it's a lot more modern so you'd think the overall engine would have improved.
