If you're like me, you probably one time spent several thousand dollars in moding an engine to try to get the best fuel economy possible only to realize that it would take an eternity to get back the money you put into the vehicle.
If you're like me you might have even went and bought an old hybrid only to realize that the thing now needs an expensive battery, catalytic converter, maybe a brake actuator and possibly even needs an engine replacement...
So what about just going back to good old simplicity? Could a simple engine that get's 30mpg trump a complicated engine that gets 40?
For those that don't have time for the video it talks about the 2.0L engine from VW between 2010 and 2015 that wasn't turbocharged, had a single overhead cam, no variable valve timing, no coil on plugs, no EGR, and an iron block.
