TL : DR version: Is there anything that can be done to improve the highway efficiency of our Mach-E other than driving slower?
Long Version:
Drove it from the Austin area to DFW and back with some driving around in Fort Worth. Efficiency on the way there was being reported as low as 2.1 miles per kwh, granted I did have a headwind, but still. I stopped in Waco to top off at EA and departed at 76% per ABRP, well, it started dropping like a rock after that going northbound. I backed it off under the speed limit out of concern for the battery SOC. When I found a car going slow in the right lane, like 65 in a 75, I tucked in behind them. My aim point was the EA charger on the west side of Fort Worth at a Sams club, in order to meet family members who had been driving in from the West Coast in their ID.4, so we could both charge and then go to dinner before we flew off to the Dominican Republic on a red-eye out of DFW.
After a week in the DR, we saddled up to drive back to the Austin area and the performance wasn't much better. We stayed overnight before we departed back for Austin as it was after 11pm before we got our baggage and got to the car. In the morning the battery was at 71% and ABRP advised me that I would need to top up before leaving the DFW area. When I put 1% more in ABRP it advised me I could make Waco, but that I would have to limit my speed to 70mph. Doable, but I elected to top up. That was a mistake, as we went to an EVgo in a HORRIBLE neighborhood in SW Dallas, but whatever. Almost got hit by a Hellcat fleeing the police on the way to the station, also. Screamed WTF right in front of my 8 year old also. So then ABRP says we need to charge to 93% for the most efficient trip home, well, my wife started getting antsy at 88% so we unplugged and drove to the Buc-ees in Temple, I still had 26% battery left so maybe we didn't need that top off after all, had I planned for Waco. Mercedes branded Chargepoint at this location, said it was capable of up to 400Kw. Wow. Well after a brief bump to 120Kwh, it scaled back to the low 70s, that was a letdown. I guess maybe because it was already 95 outside? who knows. Anyway after 26 minutes I pulled off at 80% and we made it home with 53% as planned so my wife could run her errand without having to charge. The miles per KwH was around 2.5 on the return trip, so a little better, but I had higher expectations going into this deal.
So, yeah.
We have the AWD with the standard battery. I was never expecting miracles as far as range goes. But I wasn't expecting the per KwH efficiency to be so bad with this car. I'm not sorry we bought it, we really enjoy the car. But if we get a 2nd EV it's going to have to have better highway efficiency than this, along with preferably a bigger battery.
What do you guys with the standard battery and RWD get as far as miles per KwH? I'm a little disappointed. For comparison my parents' ID.4 usually gets around 3-3.3 miles per KwH. They have the larger battery with RWD on their car. It is not nearly as fast as our car, but, I'd give up a little speed gladly for better battery efficiency.
