Yea, by the automaker. Automakers follow the rules defined by the EPA in 40 CFR 600 For EV Range Testing: A vehicle with a fully charged battery is driven continuously over the EPA city cycle until the battery is depleted and the vehicle can drive no further. The distance driven is recorded. This is repeated, again starting with a full charge, over the EPA highway cycle, again recording the distance driven when the battery is depleted. This “single cycle” test consists of multiple repeat drives of the city or highway cycle. Automakers also have the option of doing a multi-cycle test, which consists of four city cycles, two highway cycles, and two constant speed cycles.* All testing is done in a laboratory on a dynamometer. The city and highway driving ranges determined from this testing are adjusted to account for real-world factors that are not represented on the laboratory test procedures. These factors include such things the impact of air conditioning, of cold temperatures, and of high speed and aggressive driving behavior. Although the regulations allow some optional approaches, the most common approach is to use a factor of 0.7 to adjust all the test parameters, including range. For example: An EV achieves 200 miles on the highway laboratory test. Real-world highway driving range → 200 x 0.7 = 140 miles to account for aggressive driving and HVAC use. The adjusted city and highway range values are weighted together by 55% and 45%, respectively, to determine the combined city and highway driving range that appears on the EPA fuel economy label. For example: Assume an adjusted city range of 168 miles and an adjusted highway range of 140 (from example above). The official combined range value → (0.55 x 168) + (0.45 x 140) = 155 miles (values are rounded to the nearest whole number).

I use a system with integrated anti sway and the difference is felt immediately. -
not hard to see edit: played with proportions more to make it look more like the airflow graphic they showed in that presentation.

Are EV range estimates determined by the automaker, or does the EPA determine the estimates? (Seems the EPA wouldn’t since there’s no tailpipe emissions). I wonder what the range difference is between highway and city driving.
-
makes me think that the sketch they showed here was deliberate and not a red herring then. Doug Field design style?

the fact that he seems to like how the skunk truck looks concerns me
-
My job probably precludes owning an EV until charging improves (if I could charge in <10 minutes I could make it work) but I do genuinely like hybrids a lot. I feel like it captures a lot but not all the advantages of an EV without the drawbacks.
-
And Field did it in exactly the timeframe he was given - four to five years after he was hired by Ford in 2021! Thanks for sharin' that tidbit. I'm more confident now that the skunkworks and CE1 efforts are on the right track, even though Galhotra leading Product Creation and Industrialization still worries me.

I don’t like Nissan on the front. It looks fine when it’s imprinted on the back, but it doesn’t look right on the front
