Automotive columnist Mr. Dan Neil commented on the Model Y in the Wall Street Journal June 6 and 7, 2020 Saturday and Sunday edition as follows.

“The Tesla Model Y is the best car in the world”

Among middle range crossover vehicles, it is the most technically advanced electric vehicle, and while using many Model 3 components, it has excellent quietness and  acceleration performance; the implementation of its  innovative thermal management system (Octovalve) is highly acknowledged.

In addition, he refers to Sandy Munro’s activities in which he explains the technical breakthroughs of the Model Y in detail by video, praising him as an EV hero.
