Looking forward to detailed driving impressions on the R.
I can provide the detail I have after about 200 kms....
Comfort mode = I'm not sure why you would buy this car and use comfort mode but I did a test and got 8 L/ 100 KM in mixed driving (no traffic) which I though was really good.... but boring as hell.
Normal mode = Only a bit better than comfort mode for driving fun but you can flick it into sport mode from any of the three driving option modes and it responds much better, so in actual fact there are more like 6 driving modes. You can also do the individual settings to adjust all the driving aspects the way you want them.
Race mode = AWESOME...... This is definitely the way this car wants to be driven. It holds the gears really well right up to red line and launches you like a bullet from a standing start, I'd say on par with the 335. And I know the engine sound is partially fabricated but holy lord the growl it makes in race mode is something special.
The Fender audio system sounds great, you lose the spare tire to a subwoofer, it was kind of funny when the salesman tried to show me the spare tire and I had to explain to him it was in fact a sub woofer. The car sticks to the pavement like its on rails and is not overly rough on bumpy pavement, I found the 335 rougher but it might have been partially because of it's age, I'm not sure. The brakes are very good but not to grabby, and I love the "R" calipers.
The seats are very comfortable, the interior is nicely appointed and all the tech is easy to use. I love this thing. I'm headed out now to give her a coat of wax, I noticed the rain today was sitting on the paint which bothered me a bit. Then I'll do a full photo session which I will hopefully get posted tomorrow.
