I thought i would share something i stumbled into when doing a long climb of about 6% upgrade for about 15 miles. This would not nessacarily apply to short climbs. I had the thought at the beginning of the climb to use hv charge and sport mode (soc was 50%), Since fuel economy is not very good anyways when using ice to climb in a 4k lb car. The result was improved performance. It kept my desired speed of 65 mph with no angry bees. The battery never was depleted during the climb, though it was around 30% when i reached the top. I think this worked good because the battery rapidly depletes at high speeds when climbing. As standard hv mode tries to maintain soc and speed, ice revs higher and the battery depletes faster. I have done this experiment 3 times now and prefer hv charge/sport mode for this 15 long 6% climb. I felt this was worth sharing because some people have been rather uncomfortable with the cars performance in long climbs.
