Specially for the Henkel Cup (German national race 1940) rebuilt 109. Underwing cooler removed and replaced with surface coolers. The wings were clipped, the tail was enlarged for enhancing performance at low level.
VDM developed specially for this plane a 6 blade contrarotating prop to avoid the torque of the powerful upgraded DB 601-N7 engine (1550 PS with Methanol-injection).
After the first qualifying race the original Dimethylol cooling fluid was replaced with the new Trimethylpropenthol (better cooling performance). In the final race the pilot Emil S.C. Herz reached an average top speed of 663,4 km/h for all 10 laps and won the Henkel Cup.
