From Jess Weatherbed at The Verge:

Several popular models are now showing lower range estimates in the US. The move comes after the DOJ opened a probe into inflated claims, but Tesla doesn’t give a reason.

I own the Tesla Model 3 Long Range and I can confirm that while the range on my car is great, it rarely lives up to the estimated range even if I am driving fairly conservatively. Glad to see the estimates being advertised is a bit closer to reality now.
