I had my first full tank fill with the new car this week. The FE/trip meter B says I averaged about 40mpg over the whole tank. Many of those those days were below 0F and hybrid FE really suffers when temps are that cold. Most days my car will never reach full operating temp, though the grille block and oil pan heater help tremendously.
Also, my battery pack has about half the capacity cold as it does warm. I am often in forced recharge mode as I typically DWB and EOC, leaving little kinetic energy for regen.
I have found that EOC is very easy in this car - I release the throttle, then lightly depress it again until the FE gauge displays 120mpg. At that point, the engine is off until I need to accelerate again; the transition from EOC to acceleration is seamless and responsive.
I am keeping an eye out for a superbrain 989 to cycle my pack and regain some capacity. I am also looking for a solution to add a piggyback battery pack to gain further usable capacity.
