There's a reason why this is only CGI. Do some math: Solar constant is about 1kw/m^2. The car might have 5m^2 of cells if you're generous. Solar cells have an efficiency of 10-20%. Even under optimal conditions the solar cells on a car aren't going to generate more than a few 100 watts, maybe 1kW. That's great for a bicycle, decent for a moped and sucks for a motorcycle. For a car it's going to suck even more. Yes you can move something ultralight and ultra-aerodynamic with that amount of power but it won't be a car as you know it.

We warn the reader in advance that the proof presented here depends on a clever but highly unmotivated trick. -- Howard Anton, "Elementary Linear Algebra"
