Since the battery is smaller than pure BEV, it covers only 50 miles range. This means the battery charge cycles will happen every day vs BEV. With BEV, the battery is big, you charge once or twice a week. It's just the law of physic, you have a small battery, you force it to use full 100% energy every day vs big battery where you might use only 15% its energy. Since you have more charge cycles, degradation will happen. The bad thing about the small battery is degradation is a big deal. Lose 20% of 50 miles, down to 40 miles is a big deal. Whereas losing %20 of 250 miles of BEV is ok since you still have 200 miles left. So, my point is the car is not designed to be used 95% driving in EV mode. I saw a lot of posters brag about never fill up the gas tank, I wonder if they make mistake to buy Clarity vs BEV. I myself I question that all the time since I use EV mode more often than I thought.
