I think they have reinvented the wheel.
Here in Germany, Ford had tested two stroke engines with this car
(German) news about that here
. Sorry, it's German. Let Google translate that.
Back in that time, I knew about that. I wanted to buy one. 3 cylinders, 1.2 litre, 80 HP. It even had some sort of lean burn. But Ford had never sold this fine engine.
Why? Because noone would have bought it.
Just as noone had bought an Insight Mk 1 in 2000. Same story. They've been too early.
