The car isn’t without a few quirks, some of which seem to have been remedied by software updates.
A call for full power prior to the engine being at operating temperature can result in less than desirable behavior. Once up to temperature and in either Hybrid or e-Save mode the car will occasionally operate on battery power alone. Aggressive acceleration, even when coming out of EV mode, is predictable and very similar to what one would expect from a conventional vehicle once the engine is warmed up. Also, Hybrid mode focuses on efficiency, using batteries first and then going ti gas, whereas e-Save used gas and preserves the battery SOC. I am typically in either EV or e-Save, so I don’t have much experience with aggressive acceleration in Hybrid mode. It could be that Hybrid mode is trying to avoid using the engine while accelerating while e-Save mode is happy to go full gas.
There are 2 regen settings, default and max. I prefer max. Some drivers do not care for it. There is a noticeable transition just before coming to a complete stop while in max, that does not occur on the default setting. A software update did make it less noticeable. It could be a transmission shift or a transfer of braking power from regen to hydraulic braking, or a combination of the two. The braking system on the Clarity handles that situation flawlessly.
