Too soon to tell really , first impressions , as I've only done about 150kms, I'm taking it easy - the engine feels more torquey below 3,000 rpm (mine's a EDC), so I can't tell you above 3k rpm yet. Being a hatch it's certainly more practical, the seats are comfortable , but the Recaro's in the 275 look better. The ride feels about the same in inner-city Sydney. Everyone told me to be careful as the new car turns in very easily due to the 4 wheel steering, but after the S3 , I can't tell the difference yet.. The hatch does have a nice solid feel to it, but whether it feels as agile as the RS275, I can't tell you yet.
The dullness and quiet , is why I no longer wanted a VAG product. I had GTI manual, then followed by the S3, both had stage 1 tuning. The S3 was extremely quick, but bugger all driving engagement , on the GTI you can't switch off the ESC totally, so even less driver engagement.
