I'm sure it would not work, and here's why. To move the car as efficiently as possible, it has to be aerodynamic. If you introduce something like a turbine, you are increasing friction.
The question is: Can the increased friction be used to charge the car's batteries?
No, because no matter what, it can't be done efficiently. Not 100% of the increased friction can be converted into 100% electrical energy. Some of that air friction is lost to turbulence, or pushed to the side of the turbine instead of being used to turn the turbine, and some of it is lost to the mast that would hold the turbine up and away from the car. There is of course all that extra weight that the car needs to take long with it too.
I don't know the math, sorry, but I know the idea would not work.

that electric truck in your OP there? it has a drag coefficient in the upper .45s, easy, that's a wall. combined with the turbine blade technology and the lightweight materials wind turbines are made of and the ULTRA efficiency of wind power, wind turbines crank out massive amounts of power for their size and extremely efficiently.
285 watts out of this little beast, that's = 6 SIX solar panels 2 feet x 4 feet with direct sunlight on them
again, i was simply trying to add a bit of fun to your thread, don't be so quick to brush off things.
