The project began in 1937, while the Third Reich was at the height of its powers. Automotive designer Dr. Ferdinand Porsche first aimed at a speed of 550 km / h (342 mph), but after George Eyston and John Cobb’s successful LSR. In the 1938 and 1939 races, the target speed was raised to 600 km. / h (373 mph). At fines from 1939, when the project was completed, the target speed was much higher than 750 km / h (466 mph). This would also be the first attempt to achieve the absolute land speed record on German soil. envisioned the T80 as another propaganda triumph of German technological superiority that will be witnessed around the world, courtesy of German television. The same Autobahn ride had already proven ideal for breaking records in lower capacity classes, as Britain’s Goldie Gardner topped 200 mph (322 km / h) in a 1,500 cc MG.
The huge 44.5-liter inverted Daimler-Benz DB 603 V12 was selected to power the record-breaking car. The engine was a higher displacement derivative of the famous DB-601 aircraft engine that powered the Messerschmitt Bf 109 fighter in production at the time, and the DB 603 ended up as the highest displacement inverted V12 aviation engine in production for Germany during the World War. II years. The installed DB-603 was only the third prototype (V3) engine of this variant and tuned up to 3,000 hp (2,237 kW; 3,042 PS), about twice the power of the Bf 109 or Supermarine Spitfire. The engine ran on a special mixture of methyl alcohol (63%), benzene (16%), ethanol (12%), acetone (4.4%), nitrobenzene (2.2%), avgas (2%) and ether (0.4% ). ) with injection of MW (methanol-water) to cool the load and as an anti-detonator.
The difficulty of the challenge met with money and engineering genius. In 1939, the T80 was completely completed at a cost of RM 600,000. The car was over 8 m (26 ft) long, had three axles with two of them driven, weighed over 2.7 metric tons (three short tons) and produced 3,000 hp (2,237 kW; 3,042 PS) along with the aerodynamics of the specialist Josef. Mickl to reach a projected speed of 750 km / h (466 mph). Aerodynamically, the T80 featured a closed Porsche-designed cockpit, sloping low hood, rounded wings, and elongated tail arms. In the middle of the body were two small wings to provide downforce and ensure stability; These wings were inspired by the wings of the famous Opel rocket cars from 1928
