As I understand it, even in Sport mode, you need to have at least 15% battery charge available. This is the equivalent of having a flywheel on a traditional engine that smooths out the electrical flow to the motors and also allows the ICE to turn off when the car is not moving. As long as the HV battery can hold and maintain the 15% reserve charge, Sport mode should work just fine.Maybe this is a silly question from a new member...if the HV battery craps out, will the car still run using the sport mode/2.0L engine?
I guess thats my biggest concern considering the cost of battery replacement
The car will not allow the battery to go below 15% SOC when it is running, so driving it across the country, or running in Sport mode only would not cause that. The only time you would worry about this is the long-term storage scenario.What happens if the battery actually drains completely? For example the car sits for months at a dealership? Or driving across country, only driving in sport mode?
