New Tesla Model S and X Long Range Plus vehicles get big range boost

New iterations of the Tesla Model S and Model X are boasting some pretty impressive new travel ranges, Tesla revealed on Friday.

The pages for the Model S and Model X claim that the Long Range Plus versions of these two electric vehicles can now hit ranges of 390 and 351 miles, respectively, which is a healthy bump up from the previous estimated ranges of 373 and 328 miles.

What changes were made that allow for the bump in ranges? Tesla doesn't specify, but we do know that the Model S will be getting a new style of 19-inch wheels, which probably doesn't hurt the mileage.

The more powerful Performance models of both vehicles did not get a bump in range, so whatever the company is doing it only seems to be benefiting the Long Range Plus models. Currently, the Performance Model S lasts 348 miles and the Model X can go about 305 miles. That's the price you pay for increased acceleration.
