You guys are making a Mesiah out of this G55.
It was a very nice aircraft and it could do high altitude better then the 109 and 190 but.
At low and mid altitude was not that scarry. It had the good high altitude handling and performance because of low wing loading and a lot of wing area. This tends to reduce maximum speed at low alt and to reduce the roll rate.
Did you guys see how many work hours it took to build one of this things?
That's one of the reasons it was never an option for producing it for luftwaffe. They could build 262's faster then they would have built this thing. Let's not even talk about the lost production during the retooling period for the 109 factories.The Germans could not afford that.
What hurt the German people was the bombers. That's what was important for Hitler, Goering and the citizens in German cities. The escorts hurt the Luftwaffe. And that was not as important at that point in time.
What is better? having 300 slightly better planes when it comes to fighting the escorts or 2000 190's and 109's that can engage the bombers just as well. (or almost that good in the 109 case)?
The German high comand decided to go ahead with building jets in 1943 and all developement stoped for all piston engines that were not in production.
That decision put them in inferiority in piston engine fighters in 1944-1945. Not the lack of the G55.
If they put more resources in some bigger engines that were already in testing in the begining of 1943, like the BMW-802, they could have had a scary piston engine fightes by mid 1944. That engine was producing 2600HP at take off and 1,600hp at 12,000 m (39,000 ft).
All you have to do is put it in the FW-190 airframe and increase a little the wings (like in the case of Ta152C) and you have a plane that can do everything better then G55 could ever hope for.
