Test drove a 103TSI DSG Highline today, here are some points that have stayed in my mind (from the perspective of a MY10 118TSI owner):
Top-mounted accelerator pedal - great, very light on initial uptake (similar to the new Corolla I drove a few weeks ago), no more DSG lag at all when taking off at stand-still.
Auto stop/start. I had forgotten about this and when I was stopped I couldn't actually tell if the engine was stopped or not; when I accelerated the car started immediately with no real lag (at least no more lag than a Mk6 Golf DSG7 owner would be use to). I ended up turning the feature off but then every time I stopped, the MFD showed an eco-tip suggesting I turn it on, which covered all the other useful MFD parameters. I know there is a way to turn off these eco tips just like you can choose what other MFD screens you want (speed, fuel, distance, eco tips, etc) but I didn't bother looking for it.
Electronic handbrake seems fine to use, I don't think there will be any issues with it, but I haven't tested it extensively. The auto-hold is cool feature that I could see myself using. You press it once, then every time you come to a stop, you can take your foot off the brake pedal and the car won't move at all, no time limits as far as I could tell. As soon as you start to accelerate the brake is released. In theory then, if you also had the Driver Assist Pack, you could jump on the freeway in morning traffic and not have to press any pedals at all. Interestingly, if you have a look inside a Kia Optima Platinum it's electronic handbrake and auto-hold buttons look almost identical.
Power... better than the Mk6 90TSI Trendline, not as good as the Mk6 118TSI. Enough for the average driver, but I'd like more. Steering wheel buttons were a little hard to get used to and I found myself wanting to look at the wheel for too long while driving to figure it all out so I ignored it for the test drive. Easier to see the speedo through this wheel, if I sit in the best position and adjust the wheel in the Mk6, the top of the rim blocks it in my car (can't see beyond 60kph).
Comes with front + rear sensors, RVC, BT, NAV, etc which is great. Seats are nice. No option to upgrade to the Discover Media Pro which is disappointing, (losing features if upgrading from a car with RNS510). The very nice sales person confused RDS for DAB+ so I kindly corrected her.
Am I sold? Nope, only because there just isn't enough new stuff that my car can't already do to spend the money on upgrading, plus in a few areas I'd be downgrading. The sales person said I'd love the new car menu on the touchscreen, I was too nice to mention that I can already do all that with the Polar FIS (which btw I forgot to turn off dropping it off with VW today) or on my phone via the OBD port. Plus I'm not sure if I like the idea of passengers being able to change settings via the HU. So I'll be waiting for the GTI. For Mk5 or non-Golf owners though, it's looking hard to beat if you've got that sort of money to spend. Speaking of...
