While Ferrari is best known for relatively small, free-revving V12s, the Italian manufacturer also fielded much bigger engined racers during the 1950s. Among them is this 410 S Scaglietti Spyder, which was built specifically for the 1955 Carrera Panamericana. When the gruelling road-race was cancelled, the five-litre racers were sold to privateers. Among them was John Edgar, who fielded his ex-works car with considerable success for some of the time's greatest drivers like Carroll Shelby and Richie Ginther. Much later in his life, Shelby even signed the gas tank with the message: "Mr Ferrari told me this was the best Ferrari he ever built." The second works car was sold to Sweden where it was only briefly campaigned. Compared to the other two examples, these ex-works cars stand out because of their twin-plug engines, which produced a hefty 380 bhp. In recent years we have captured both examples as can be seen in this 24-shot gallery showing the cars at Pebble Beach and Villa d'Este.
Porsche have today completed the Cayenne line-up with the launch of the Turbo S variant. Compared to the 'standard' Turbo model, the new S boasts an engine that has an additional 50 hp and 50 Nm of torque. Complementing the tweaked engine are an even more luxuriously appointed interior and exclusive 21 inch wheels. Priced at just over 150,000 Euro in Germany, the Cayenne Turbo S will be available from early 2013.
