Range is clearly better for Tesla than the competition. That being said, they tend to have a highway range lower than EPA reported - by a larger margin than other automakers.
Here is a range comparison recently posted on youtube.
For those who did not watch the video, it was done in UK with a starting outside temp of 7C (45F) dropping to 5C (41F) at the end of the trip, mostly on highways with cruise control speed set at 70 mph. They compare the range with the WLTP - shows how unrealistic is that system. When comparing with the EPA here is what you get:
Mercedes-Benz EQC -
EPA expected range 210-220 miles, done 194 miles: 88-92% of expected EPA range
Audi eTron - EPA 204 miles, done 206 miles: 101% of claimed range
Nissan Leaf Plus - EPA 226 miles, done 208 miles: 92% of claimed range
Jaguar iPace - EPA 234 miles, done 223 miles: 95% of claimed range
Kia E Niro - EPA 239 miles, done 255 miles: 107% of claimed range
Tesla Model 3 - EPA 322 miles, done 270 miles: 84% of claimed range
Conclusions:
1. EPA range is much closer to highway range than WLTP (albeit cars driven at only 70 mph - slower that most would do in US)
2. Model 3 had the longest range, but the lowest as percentage of EPA
3. Good news for future Taycan owners: highway range in less than ideal conditions should be close to EPA range - one would expect it should behave similar to the e-tron.
I think the biggest issue for non-Tesla EVs now is the lack of reliable, high quality charging infrastructure.
