I took out the A7 S Line 3.0TDI for a test drive. It has the same bi turbo engine and transmission as the SQ5 I have on order. Performance from that engine is awesome. As expected, the acceleration is instant with a deep growl which stirs the soul. What did surprise me is how comfortable and refined it is when cruising. The engine has a nice muted tone and purrs nicely. One just has to touch the throttle gently for instant response making overtaking effortless. The 8 speed gearbox is a revalation, with silky smooth changes. It is so much better than the S Tronic. No hint of that notchy change or hestitation when pulling away from rest which plagues the DCT in the Q5. Handling is very good for such a large heavy car. Speed is so effortless that it is easy to get carried away. I found I was often going far quicker than I would normally and found myself using brakes where normally I just ease off when approaching a corner. The brakes were not as good as I would like. I had a lot of fun and managed, what I considered to be fair fuel consumption, 33mpg during my day with the beast.
