According to Tesla's US website, Tesla revised the range estimates for some versions of the Model S, X, and Y models on Thursday, with some models showing lower range than before. The basic model Y has a range of 242 to 260 miles, the long-range version has a range of 292 to 310 miles, and the performance version has a range of 285 miles. This means that the range of the company's two most popular high-end models has decreased by nearly 20 miles. The order pages of Model X and Model S also display similar changes in estimated range. The range of different versions of Model S and Model X has been reduced by up to 37 miles. The prices of these models remain unchanged.
