Our climate doesn't care if the engine is 14% more efficient. That is still vastly too much carbon emission for people or goods to move from A to B. Consider every time any ICE engine moves anything, those emissions will warm the planet for millennia. We can not afford to use these destructive engines, even though fossil fuel interests make them slightly less damaging. We must have a sustainable transport system, which ultimately means using non-fossil derived fuel. That means way way better batteries, fuel cells, or other up and coming solutions. Any iteration on ICE is just kicking the can down the road.
