Karl Ludvigsen only gives some figures of its record-breaking attempts: 274.4 mph for the kilometer, and 248.3 mph for the mile. (Feb. 1939 by Rudolf Caracciola). Subsequently, they went on to develop a similar W125 for the 1940 Grand Prix season, that never started. The bodywork was similar, with a Cd dropping from 0.599 to 0.293.
