It's interesting that some of the cars with large differences between cold & warm have there EPA ranges closer to the the cold temperature range, whilst others are closer to the warm range. It's as if some manufacturers have chosen the lower range for their EPAs, so will be less disappointing and appear better in warm weather than promised. I would expect consistency but this is one the flaws of comparing cars specifications: there isn't a truly accurate and constant way to measure ranges that consumers can trust (the same is true for MPG estimates for ICEs).
