BMW 801E, why wasn't it built?

[wiking85]

Given its 2000hp performance, why wasn't this engine produced? AFAIK it was ready in 1943. Did it require too many strategic raw materials? How did it differ from the 801S? Was it just a bomber engine? Thanks for any help.

"The E model was not widely used. Instead, continued improvements to the basic E model led to the BMW 801F, which dramatically improved performance across the board, with takeoff power increasing to 2,400 hp (1,790 kW). It was planned to use the F on all late-model Fw 190's, but the war ended before production started."

So it did enter production? Why wasn't the 2000hp rating worth besting the D-series 1700hp in production? Why was the S-series put into production long before the F-series was supposed to be entered into production?

No 801E except prototypes and development engines. Most likely because it required far too many changes to the machinery and they couldn't afford the production loss. But the 801E development led to lots of improvements in the 801D-2 and to the stronger 801S. The 801F was the successor to the 801E and was slated to begin production in spring 45.
