The claim can be whatever it wants. The fact of the matter is that your available capacity on anything other than motorized tracking panels is going to be about 30% of ideal while sill having a reasonable hope of being aerodynamic. The realities of the application at hand are at odds with the claim. Also worth noting is that the kind of days that would provide this level of solar performance (assuming everything else works by magic) would also necessitate climate control for the benefit of battery pack and driver. The solar car concept has fundamental issues; I worked on a solar car competition in college and it was only possible with future solar panels, future energy storage, future efficiency gains, and zero utility for the user. Like much of what gets posted on this sub, it’s CGI wishful thinking
