I found about 250 miles for the e-Tron and 315 miles for the Model X competing WLTP ratings. I imagine aerodynamics are a huge factor in this difference.

- kenhwang 7y agoFor 83.6kWh usable battery on the e-tron vs 95kWh on the Model X.
- mikeash 7y agoAh, I just saw 95kWh and figured it was close. I didn't realize the usable was so different. I'm a bit suspicious of the WLTP ratings for these cars. The EPA rating for the Model X Long Range is 325 miles, while the e-tron's EPA rating is only 204 miles. Any idea why the Model X would score lower on WLTP while the e-tron would score so much higher?
- kenhwang 7y agoThey probably just have different blends of city/highway/speeds. Just like how gasoline cars have different estimates from different testing agencies, electric cars do too because they all have different efficiency curves. The ratings generally try to mimic the driving conditions of the region and automakers tend to optimize for their home turf. So it's not too surprising the American automaker does better on the American test and the Europeans do better on the European test.
