Hello ladies and gents this is the viking telling you that today we are talking about

PORSCHE CARRERA RS

The Carrera RS models, valued by collectors, are considered by many to be the greatest classic 911s of all-time. RS stands for Rennsport in German, meaning "racing sport". The Carrera name was reintroduced from the 356 Carrera which had itself been named after Porsche's victories in the Carrera Panamericana races in Mexico in the 1950s. 

The RS was built so that Porsche could enter racing formulae that demanded that a certain minimum number of production cars were made. Compared with a standard 911S, the Carrera 2.7 RS had a larger 2.7 L; 164.0 cu in (2,687 cc) boxer-6 engine with a bore x stroke of 90 mm × 70.4 mm (3.54 in × 2.77 in) developing 210 PS (207 hp; 154 kW) at 6,300 rpm and 255 N⋅m (188 lb⋅ft) of torque at 5,100 rpm with Bosch Mechanical Fuel Injection,[6] revised and stiffened suspension, a "ducktail" rear spoiler, larger brakes, wider rear wheels and rear wings. 

In RS Touring form it weighed 1,075 kg (2,370 lb), in Sport Lightweight form it was about 100 kg (220 lb) lighter, the saving coming from the thin-gauge steel used for parts of the bodyshell and also the use of thinner glass. In total, 1,580 were made, comfortably exceeding the 500 that had to be made to qualify for the vital FIA Group 4 class. 49 Carrera RSR cars were built with 2.8 L; 171.4 cu in (2,808 cc) engines producing 300 PS (296 hp; 221 kW).

In 1974, Porsche created the Carrera RS 3.0 with mechanical fuel injection producing 230 PS (227 hp; 169 kW). It was almost twice as expensive as the 2.7 RS but offered a fair amount of racing capability for that price. The chassis was largely similar to that of the 1973 Carrera RSR and the brake system was from the Porsche 917. The use of thin metal plate panels and a spartan interior enabled the shipping weight to be reduced to around 900 kg (2,000 lb).

The Carrera RSR 3.0 and Carrera RSR Turbo (its 2.1 L engine due to a 1.4x equivalency formula) were made in low numbers for racing. The turbo car came second at the 24 Hours of Le Mans in 1974, a significant event in that its engine would form the basis of many future Porsche attempts in sports car racing, and can be regarded as the start of its commitment to turbocharging.

I hope you liked this post and as always have a chilled day from the Viking.
