Shouldn't be a surprise. This is what was being advertised on acceleration and was in the press. From GreenCarReports on February 28, 2019 "Tesla Model 3 Standard Range Arrives Soon at $35,000 and 220 Miles. Really.":
"The Standard Range model, which costs $36,200 after a mandatory destination and documents fee, is listed with specifications that include a 130-mph top speed and a 0-60 mph acceleration time in 5.6 seconds.....
Another new Model 3, the Standard Range Plus, will cost $38,200 and bring 240 miles of range, with a top speed of 140 mph and 5.3-second acceleration."
Where's the confusion or surprise?
Just sad the number of disparging remarks about this company I see on this forum and the misinformation spread. I get it when it comes from short-sellers who are looking to profit themselves.
