Weather was nearly identical in both trips and the freeway sections of the routes were identical. Both trips immediately followed a full-range Supercharge (238 mi is what I get on my 2017 75). Yuma > San Diego > La Jolla Trip #1 Left the Yuma Supercharger and drove around town for the afternoon doing a couple errands and put maybe 10-15 miles on it. Then drove to San Diego without stopping (170 miles). Drove moderately aggressively (70-75). In the morning, I drove 15 miles to La Jolla VERY conservatively. GPS said I wouldn’t make it – but I got it done easily with a little drafting and keeping it at ~55. Trip #2 Left the Yuma Supercharger and immediately drove to San Diego without stopping (170 miles) Drove very aggressively (75-80). In the morning, I drove 15 miles to La Jolla at a normal pace (with a bit of traffic). GPS said I would make it easily but it ended up being closer than I thought. Question #1: What is the deal with the total kWh burn in BOTH trips. Why am I so far from 75 kwh? I expected the low 70s or, at worst, high 60s. What’s going on? An extra 5-10 kWh would really help me for this scenario. And as the car ages, I won’t be able to do this trip at all. . . Question #2: Where did the extra 2 kWh to burn come from in the second trip? The second trip was a lot more aggressive so I got less range – but I could have used those precious kWh the first time around. What am I missing?
