After a brief drive at the GM proving ground in a pre-production prototype, it was clear that if nothing else the changes done to create a hybrid full-size SUV have resulted in the most refined large truck GM has ever built. The mantra repeated during the presentation was seamless integration. It's incredibly quiet even with the engine running. There are no noticeable transitions between driving modes and it all just seems to work. GM is still doing some tweaking to calibrations, but they are very close.
