I purposely put the car in Hold mode with about 19 miles left on battery gauge. This forces the generator to run. The car did the climb wonderfully. At one point I passed an Suv and found myself doing 75 mph up the canyon. The generator really revved up after this pass!! Very different feel from most cars because the motor speed is controlled by demand and is not coupled to the throttle. At the peak I jumped out to see if the grill shutters were open, but they had not moved.
After going over the peak I shifted to regeneration (L) and dropped down into Midway. The battery meter just kept climbing until it hit 60 miles!!! I must have actually been charging the top 20% of battery capacity that GM reserves.
Overall we did 138 miles over a very steep route and used about 1.7 gallons of fuel and 10kw of electricity.

I have yet to get big regen numbers but have a decent hill to regen on the way home that I use. I make sure I work my way up to 60 by the time I get ready to go down and I let it do full regen in L until I get to about 35mph. Then I gradually speed back up to 55 in the valley before the hill climb. I usually end up with 4 miles more range than I had before the hill at the top of the next hill. Makes me feel like I'm breaking physics.
