The Bf 109C variant was the last production model of the 109 fighter series designed to use a Jumo engine. The engine it mounted, the 700 horsepower Jumo 210Ga, was fuel-injected, providing it with greater high-altitude speed and maneuverability. This new fuel-injection system also greatly decreased the chances of stalls during dives. Unlike traditional carburetor engines, the Jumo 210Ga would not lose power under negative g-force. The new engine changed the overall shape of the aircraft. The under-nose air intake was now much larger than older Messerschmitt fighters.
