RBW Thanks for the reply: the graph shows very much what it feels like. The other day I drove my Roadster and P4 back to back on identical routes. Traffic was equally light on each trip with the odd lorry on long hills. Maximum fifth gear speed slightly topped 90kph. The difference in acceleration is noticeable of course in that second gear in the Roadster, is a massive shove which quickly carries one past an obstacle: in the P4 however it seems as quick : it is the delivery which is different. I think it was Dave W who thought that the P4 did not give much away to his Roadster and I tend to feel the same. Second gear will run out at just above the British national motorway speed limit whereas the Roadster needs a gear change up before 60mph. Tractability in the latter is slightly better but again not by much. I have now reached 4000 klms in the P4 and the exhaust is still clean. I can only keep one of these cars and the decision is not easy. I suspect the Escape engine is bullet proof whereas I am not so sure of the GDI. If I could have my Roadster in Black, with the removable rear panel (the Roadster is the Sport model) and alloy wheels, and had the same Suage Green interior then I would lean its way. If the P4 could have the 3:0 litre engine, I would keep it.
