Type B built in 1935 was the second car in series of Auto Union racers produced in 1934 – 1939. The car was based in 1934 A-type model, but with very significant modifications. The original Porsche-designed V16 engine now had bigger valves and new cylinders, increasing compression from 7 to 8.95. The displacement of the engine was increased to 4,954 cubic centimeters (instead of 4,358 cc in A-type), as well as compressor pressure (0.75 bars vs 0.61),which resulted in the increase of power to 375 PS compared to 295 PS in type A. Chassis was constructed using new longer 105 mm chassis tubes. The cooling system was totally rebuilt with the frame no longer carrying water to the radiator. The two tanks were replaced with a single 210 liter main tank behind the driver keep fuel for 320 km Grand Prix distance.
