It was soon obvious what was the main shortcoming of the Fw 190: lack of real high altitude performance. As early as 1941, various solution were studied to solve it featuring mainly new power plants with better superchargers and even the use of turbochargers. The C-series was conceived to follow the later approach. A bunch of prototypes were built, but in the end they proved too complicated and finicky. The D-series, with liquid cooled Jumo 312, proved to be the best option.
The Fw 190 V18/U1, the first real C-series prototype, in all its glorious splendour. This prototype was powered by a Daimler-Benz DB 603G engine. That not very refined ventral “pouch” fairing housed the DVL TK 11 turbocharger installation. Easy to understand why it was nicknamed the Kanguruh (Kangaroo).
By the way, this is my favourite Würger.
