Do215 was the serial designation assigned to the export version of the Dornier Do17Z. It was powered by the Daimler Benz 601 A-1 in-line engine which made it some 66kph faster than the radial engined Z-2. With its higher performance it was initially decided to use the Do 215 in the bomber/long-range reconnaissance role as the B-1/3 and the purely reconnaissance model B-2/4.
