The Type 547 engine could have used an engine-mounted chain or gear drive system which would have been much less complicated but would have increased the length of the engine. Zero-to-sixty took less than 10 seconds and top speed was achieved at approximately 137 mph (220 km/h). Its aerodynamic body, excellent weight distribution, low stance, and tipping the scales at a mere 1,200 pounds made it incredibly agile and its advanced four-cam engine meant it was quite powerful relative to its weight. The positioning of the engine and transmission gave the Porsche 550 a balanced weight distribution and largely neutral handling. A five-speed gearbox was put into service beginning in 1956. Subsequent tuning revisions eventually raised that figure to 180 HP. The engine initially produced 110 horsepower at 7,000 RPM and 121 Nm (89 lb-ft) of torque at 5,000 RPM. A limited-slip differential controlled excessive slip to the drive wheels during cornering. The fully synchronized four-speed gearbox was overhung at the rear. An external oil cooler in the nose joined the wet-sump lubrication system. A very efficient v-belt-driven fan was mounted ahead of the rear axle line and provided the air-cooling to the engine. There were 14 bevel gears to route the crank's rotation first to the exhaust cams and then to the intake cams. Four roller-type main bearings were used to minimize friction loss, made possible by the Hirth-patent built-up type crankshaft and the inclined two valves per cylinder. There was an aluminum crankcase and two twin-choke downdraught Solex carburetors. It featured four shaft-driven overhead camshafts, 9.5:1 compression, two heading each twin-barreled cylinder bank, twin-plug ignition with two plugs, two coils, and two distributors driven from the upper camshafts. Hydraulic drum brakes provided the stopping power.Īn all-aluminum, naturally aspirated, 4-cylinder boxer engine, known as the 'Fuhrmann Engine' (Type 547), was mounted mid-ship, ahead of the rear axle, and had a displacement size of 1.5 liters (1,498cc). The wheelbase measured 82.7 inches, had a width of 63.4-inches, stood a mere 38.6 inches tall, and had an overall length of 145.7 inches. The first two 550 prototypes used this rear setup, while subsequent examples used trailing arms to control the Porsche swing-axle system. An independent arrangement suspended the 550 at the front and rear, with twin trailing arms and transverse torsion-bar springs at the front and a leading-arm rear setup. Even the dash panel acted as a transverse stiffening member, welded to the sub-structure. The Porsche 550 used a ladder frame composed of welded steel tubes and further strengthened by its aerodynamic lightweight aluminum body paneling, rigidly-attached to create a kind of semi-monocoque structure. ![]() They would become some of history's most important and successful race cars, earning both class victories and overall wins. ![]() The first genuine racing car design from Porsche was the 550 Rennsport Spyder, launched in 1953 at the Paris Salon and the catalyst that birthed the 550A and 718 successors. Ferdinand Porsche's consultancy direction. The small-capacity aerodynamic production Coupe designs were based upon Volkswagen technology, with origins dating to the 1930s for 'the people's car' under Prof. Additional accolades include class victories at the 19 Mille Miglia. The coupe, with its streamlined aluminum coachwork, won its class (751 to 1100cc) and placed 20th overall, with Auguste Veuillet and Edmond Mouche at the wheel. The Porsche-built 356 SL (Sport Light) 'Gmünd-Coupe' were raced with enviable success, competing at the 1951 Le Mans 24 Hours which made them the first and only German manufacturer to compete. The so-called Glöckler-Porsche lightweights, particularly the 1953 Glöckler-Porsche 1500 Super, are acknowledged as the inspiration for, and direct predecessors of, the Porsche 550. The formula was improved upon with the 1.5-Liter Porsche engine which earned them the class lap record at the major Freiburg-Schauinsland mountain climb. With its low weight and potent engine, it had a promising power-to-weight ratio. They used a welded tubular chassis frame and mounted a 1,086cc air-cooled Porsche 4-cylinder engine just ahead of the rear axle. Among the more successful ventures were Walter Glöckler, a Frankfurt, Germany-based Volkswagen and Porsche dealer, and engineer Hermann Ramelow who constructed a series of racing specials beginning in the late 1940s. LEGO Speed Champions Porsche 911 Turbo 3.Porsche and motorsports have been inseparable throughout its existence, and its endeavors during the early 1950s relied on outsiders to explore the inherent performance potential of its offers. ![]() Hoonigan Rauh-Welt Begriff Porsche 911 Turbo ↑ Vehicle name in titles before Forza Horizon 4.
