Tesla Model S now first ever electric vehicle to receive EPA range rating above 400 miles! https://t.co/EOTwVfvHS5

Until recently, the Model S Long Range Plus EPA range stood at 391 miles, but between Tesla and the EPA that was a cause of dispute.
Tesla CEO stated last month that the rating was due to an EPA error causing the car to lose 2% of its range when tested. But this was disputed by the government agency and the car was properly tested. Musk then told us that when the EPA reopened the car would be re-tested.
The Verge knows that the re-tested result is the new 402-mile rating.
Tesla detailed changes to the 400-mile barrel in a blog post which accompanies the announcement.
These include reductions in weight in components such as the car battery pack, more aerodynamic wheels and more efficient drive drives.
Renewable improvements to blocking also mean that more energy is returned to the battery pack during driving.
