"Apart from being very fast and exciting, the Porsche is a practical car. Unlike most rivals which can be regarded as Sunday morning adrenalin pumps because of their intractability, or cramped accommodation, the Turbo can be used as comfortable daily transport. Yet its handling and roadholding are probably as good as any other car in the world. Few, if any, cars have impressed us so much." - Motor magazine, 8th November 1975.
Anyone that has driven a Porsche 911 Turbo will agree with the above, whether they are a professional road-tester or merely one of thousands of enthusiastic owners. Indeed, one of the most celebrated of the former, Paul Frère, declared that the Porsche 911 Turbo offered "the finest blend of ultimate performance and refinement I have ever come across..."
Much of the Porsche 911's development had resulted from the factory's CanAm racing programme with the Type 917 sports-racer, and it was the then Group 4 homologation rules, which required 400 road cars to be built, which spurred the development of 'Project 930' - the legendary 911 Turbo. In production from April 1975, the Turbo married a KKK turbocharger to the 3.0-litre Carrera RSR engine, in road trim a combination that delivered 260bhp for a top speed of 250km/h (155mph). But the Turbo wasn't just about top speed, it was also the best-equipped 911 and amazingly flexible - hence only four speeds in the gearbox - being capable of racing from a standstill to 100mph (161km/h) in 14 seconds.
The Turbo's characteristic flared wheelarches and 'tea tray' rear spoiler had already been seen on the Carrera model, while the interior was the most luxurious yet seen in a 911, featuring leather upholstery, air conditioning and electric windows. For 1978 the Turbo's engine was enlarged to 3.3 litres, gaining an inter-cooler in the process; power increased to 300bhp and the top speed of what was the fastest-accelerating road car of its day went up to 257km/h (160mph).
In 1986, the Type 930 was reintroduced to the US and Japanese markets fitted with a 278bhp emissions-controlled engine, coincidentally with the release of the Targa and Cabriolet versions that would prove so popular. Refined over the years while retaining its high performance edge, the 930 Turbo sold in the thousands, becoming the definitive sports car of its age. When Porsche revealed that the original 911 would be replaced by the new Type 964 in 1990, dealer stocks of the existing Turbo model sold out overnight.
The rare Porsche 911 3.3 Turbo Cabriolet is now considered a 'cult' car thanks to numerous appearances in Hollywood movies and on television, most famously Miami Vice. Built to US specification, this wonderful example comes with a Porsche Certificate of Authenticity (CoA) recording its original colour scheme as Silver Metallic with black leather interior and matching soft top. The CoA also lists this car's numerous desirable factory options. Highlights include the following:
- Blaupunkt Reno radio
- Oil cooler with fan
- Locking differential
- Electric cabriolet top
- Passenger side mirror (electric plain)
- High intensity windscreen washer
- Headlight washer
- Velour carpet in luggage compartment
- Windshield green graduated tint
- Protective side mouldings
- Air intake slots in the rear wings
The aforementioned air intake slots were usually reserved for the 'slant nose' model, and our vendor believes that his is one of only a few regular 911 3.3 Turbo Cabriolets combining this option with the locking differential and protective side mouldings.
The Porsche had only one owner, in Ohio, before being sold in 1990 to the international dealer German Auto Specialists with only 9,306 miles recorded (documents on file). German Auto Specialists sold the Porsche to the current Belgian owner that same year (invoice on file). In the present ownership for 35 years, this 911 Turbo has been meticulously serviced and kept strictly original. A renowned Porsche expert has carried out an extensive inspection, taking 131 paint thickness measurements, and confirmed the car's originality: exterior/interior in exceptionally good condition, never restored; accident free; and multiple factory markings still present (chalk marks, spare wheel, labels and identification, etc). The Turbo is said to be mechanically excellent having benefited from an engine overhaul in 2021 (see invoice totalling €40,000 on file). The current mileage total is 31,600 (approximately 50,500 kilometres).
