Here are more details for you. When I read this it appears the new battery is 3kwh smaller, or about 10 miles. The rest of the range reduction is probably due to the new motors. Hopefully over time the software driving those more powerful motors can be tuned and give us some additional range.
What I like best about the new battery pack is the thermal enhancements so it can add 175 miles in 15 minutes. My X75D takes almost an hour to add that many miles.
