However, the problems were not cured, and only a handful were built. The RLM had been waiting for three years at this point, and eventually gave up and had all designs based on it look for alternate engines. Later that year, they gave up on that as well, and cancelled the entire Bomber B program outright. 333:, the 222 was a huge leap in performance. It had only slightly larger displacement than the 801's 41.8 L (2,550.8 in³), and about 25% more than the 605's 35.7 L (2,178.5 in³), but delivered considerably more power, 1,850 kW (2,480 hp) compared to 1,193 kW (1,600 hp) in the 801 and 1,119 kW (1,501 hp) in the 605. That represents 40 kW/L for the 222, while only 29 kW/L for the 801, and 31 kW/L for the 605.

Looking at a complete Jumo 222 from a "nose-on" view, the half-dozen cylinder banks were arranged at 60° equal angles from each other, such that neighbouring banks had their exhaust ports (at the "60°, 180° & 300°" spaces) and intake ports (at the "0°, 120° & 240°" spaces) facing each other,

The Jumo 222 was a massive and very costly failure. 289 examples of the Jumo 222's were built in total, none of which saw active service. It also served to seriously hamper Luftwaffe piston-engined designs from 1940 to 1942, while many personnel within the Luftwaffe's government-operated technology

The four-cylinder-long multibank design resulted in a shorter engine than the Jumo 211, by roughly 80 cm/31.5 in, but larger cross-section nacelle design. Like the Ju 88, it could use an annular radiator to cool the 222's cylinders and motor oil. The
