I haven't tried Insane mode yet, lots of rain right now, but I will soon. The car is amazing. Coming from my P85+ (October 2013 build) my initial observations, in no particular order, are: It's quieter. The arm rest leather is different, feels a bit more durable. The brake pedal is easier to press and responsive. Regen is better! It seems to be easier to get between 30-60 kW without the car slowing down as much with Standard mode set. As stated earlier, the steering sensitivity no longer listed in settings. I feels like Standard mode; harder than Comfort, easier than Sport. There's less resistance from the new turn stalk when shifting gears. Not sure if it's just having new tires, but man, in Sport mode I can't get the slip at all on the rainy wet roads. The next gen seats are MUCH better, more comfortable, more supportive. You do lose the kangaroo pouch on the driver's side which I'll miss. I'll add more as I drive the car more.
