Just got all the info from Cessna. My old man might be buying one. The MTOW is a tad over 8800 so not really much of an increase. Cruise speed realistically is about 14 knots quicker than the standard grand van with about 70 lbs and hour extra fuel burn at that speed. So speed and performance is the biggest change. ROC increases to about 1250fpm. I'm still trying to find out if it can be fitted with the APE kits or its not really worth it. I was hoping for a much bigger MTOW increase.
