For the 1972-1973 period, this refers to the early turbo variants often based on the 2.7-liter Carrera RS engine, featuring a single KKK turbocharger. The Carrera RS 2.7 was the precursor. The 'Carrera Turbo' often refers to the racing variants like the 1973 Carrera RSR 3.0 Turbo or the early development of the 930 Turbo, which were heavily based on the air-cooled flat-six architecture. Performance Performance: Early turbo models (1973 Carrera RS 2.7 Turbo homologation) produced approximately 300 PS (221 kW; 296 bhp). Torque figures were significantly higher due to the turbocharger. Specific output varied by racing homologation and tuning. Fuel System Fuel System: Bosch Mechanical Fuel Injection (K-Jetronic or similar mechanical injection systems adapted for turbocharging). Early systems featured a mechanical air flow meter and fuel distributor. 🔧 Transmission Standard Standard: 5-speed Manual Transaxle (Type 915) Optional Optional: N/A (Manual transmission was standard for these performance variants). Features Features: Synchromesh on all gears, rear-wheel drive, often featured a limited-slip differential (LSD) in performance variants. 📐 Dimensions Exterior Exterior: Wheelbase: approx. 2,271 mm (89.4 in). Length: approx. 4,161 mm (163.8 in). Width: approx. 1,661 mm (65.4 in). Height: approx. 1,320 mm (52.0 in). Specific dimensions can vary slightly between early turbo variants and homologation models. Weights Weights: Curb Weight: approx. 1,100-1,200 kg (2,425-2,645 lbs). Dry Weight: approximately 1,050 kg (2,315 lbs) for homologation models. 🛡️ Safety Features Ratings Ratings: Safety ratings were not standardized in the same way as modern vehicles. Focus was on driver control and active safety features. Active Features Active Features: Powerful disc brakes on all four wheels (often ventilated front and rear), precise rack-and-pinion steering, balanced weight distribution, robust chassis, sporting suspension tuning. Passive Features Passive Features: Reinforced chassis, safety glass, bucket seats with significant lateral support, three-point seatbelts, padded dashboard (evolving through the early 70s). 💡 Technology Features Infotainment Infotainment: Basic AM/FM radio, often with an integrated cassette player. Speaker systems were rudimentary by modern standards. Driver Assistance Driver Assistance:...
