I think I’ll hedge my bets and assume that the 1988 VW Scirocco nicknamed the “Car-puccino” won’t be mass produced. Mostly because it’s not efficiently run on coffee grounds. It costs between 25-50 times more than a regular car that runs on gasoline.
Not exactly the answer to other hybrid cars but it’s still lots of fun to experiment!
