CEO Elon Musk congratulated the Tesla team after the Model 3 got 350 miles of range on a single charge in a new test on range mode.

Officially, Tesla Model 3 Long Range had a range of 310 miles on a single charge, but Tesla has found some optimizations in recent months – leading to an increase of EPA-rated range to 322 miles.
Now Consumer Reports conducted its own test of the car – confirming the EPA rating.
More interestingly, they also conducted a test with range mode and achieved 350 miles on a single charge:
“At CR, we’ve found that our range testing has matched the EPA’s testing within single-digit percentage points. Our tested Tesla Model 3 matched the 310 mile range the EPA had pegged it at, and in Long Range mode we achieved 350 miles.”
Musk shared the report, which praises Tesla’s efficiency, and thanked his team for the hard work:
