The Gutbrod Heck 504 was a pickup truck that Gutbrod Motorenwerke built in Plochingen from 1946 to 1950; From October 1949 there was the Gutbrod Heck 604 with a more powerful engine. They were box vans and flatbed trucks with a tarpaulin, the payload was 750 kg. Wilhelm Gutbrod took up his production of light commercial vehicles with rear-wheel drive , which had been stopped by the Schell Plan of the Nazi regime before the war .
engine and gears
The rear 504 had an air-cooled four-cylinder two-stroke - boxer engine , which as an auxiliary engine for sailplanes had been developed. It had a displacement of 492 cm³ with 12 HP in the weaker version and 576 cm³ with 14 HP in the more powerful 604 model . The engine was manufactured by Albert Hirth AG in Zuffenhausen . The engine and a non-synchronized gearbox with a center shift lever were installed far back under the loading area, the engine behind and the gearbox in front of the rear axle. In the advertising it was said that “the engine, which is easy to handle for maintenance”, was “encapsulated so as to be dust- and dirt-tight”, but later descriptions criticized the fact that the rear engine was “without protection from dirt”. The transmission was described as follows: “Easy shifting and thus flexible and economical driving style thanks to high-performance ZF transmissions with three forward gears and one reverse gear.” The manufacturer also promised “great pulling power even when the spacious loading area is fully loaded.” The maximum speed was at about 60 km / h. According to a test report in the magazine Das Auto from 1947, the small transporter consumed "depending on the load and road conditions about 8-10 liters" of fuel per 100 km.
Chassis and body
The car was built on a central tubular frame with a driver's cab and closed front hood as well as a flatbed or box . The loading area of the flatbed truck was 2.20 m long and 1.65 m wide. The front wheels were attached to two transverse leaf springs lying one above the other, the rear wheels were attached to a pendulum axle with coil springs. The foot and hand brakes were operated mechanically and acted on all four wheels.

In the 1947 test, the advantages of air and fan cooling were highlighted: “No frost damage and cooling impairment due to rust or scale, no water pump and radiator defects, low weight and space savings, the engine quickly warms up when starting cold, or when the two-stroke engine is mixed and lubricated hardly any difficulties and, as a result of rapid heating, takes place without wear to pistons and cylinders. No maintenance by topping up water, re-tensioning and replacing the fan belt, no sealing and lubrication of the water pump or renewal of the cooling water hoses, etc. "In contrast, a more recent source reads:" The four-cylinder two-stroke unit [...] proved to be poorly stable - At first it rained complaints on Wilhelm Gutbrod's desk because of the thermal instability of the engine. "
With a price of 4,395 DM, the Gutbrod Heck 504 was significantly more expensive as a platform truck in 1949 than the Goliath tricycle GD 750 , which was also designed for 750 kg payload and cost 3,600 DM. 2,649 of the Gudbrod Heck 504/604 were built; the Goliath GD 750, which was on the market two years longer, was sold around 30,000 times.
