As well, the potent fuel-injected Borgward 16-valves fours, were loaned to Stirling Moss Ltd and the British Racing Partnership for use in Cooper chassis for the 1959 Formula 2 season. Bristow raced one successfully for BRP and Moss took his Cooper-Borgward to the British F2 championship. In fact only the financial collapse of Borgward at the end of 1960 kept the company from being a serious supplier to competitors in the 1961 1½-litre Formula 1. German privateer Kurt Kuhnke rescued some of the engines and sought but failed to qualify one for the 1963 German GP in his Lotus-Borgward.
Das ist was Karl Ludvigsen über diese Thema schreibt. Er endet das Kapitel mit folgenden Worten.
From its initial output of 130bhp, refinements in inlet and exhaust tuning brought the power of the RS four to 165bhp at 7’500rpm. Weighing 282lb (128kg), the engine could be held at full throttle on the dyno at 8’000 revs for as long as ten minutes. Thus compared to its contemporary rival, the 1½-litre Coventry Climax FPF, the Bremen-built engine scaled 25lb (11kg) more and delivered a bonus of some 20 horsepower. Those extra horses would have come in handy in the Formula 1 racing of 1961.
