First the rotary engine was to take over, then some weird engine which never made it to any cars.
If you read Motor Trend mags from the 1970's the thought was V8 engines and maybe gasoline engines all together would be gone by the 1990's
I'm making no guesses about the future but would not shock me if in 2050 there still be V8 engines in some normally priced cars
I know Carter--I mean Obama wants us to have 55 mpg cars by 2025 but look what Jmmy wanted and look what happen
I see no advantage to it at all, and if there's ANY wear in the gear train, the massive parts failure will make an AA/F explosion look like a college freshman lighting a fart
That wont work. Theres nothing maintaining piston cylinder alignment. pistons and cylinders cross the centers of the rotating crank hubs so the power take off could only be the outer or side face(s). Cute cartoon though.
