1989 Porsche 911 Turbo S “Sonauto”

The 7th of 10 produced worldwide


Beginning in the early 1970s, Porsche had demonstrated the worth of an exhaust-driven turbine for developing tremendous power for a given engine displacement, astounding the racing community with its World Endurance Championship-winning 917s. The company was quick to adapt turbocharging to its Group 4 Type 934 and Group 5 Type 935 racing coupes, basing those ferocious machines on the street-driven Type 930. Throughout the later 1970s and into the 1980s, the 930 evolved into an ever-more sophisticated, luxurious, and powerful road car.

By 1987, the Turbo boasted a 3.3-liter engine, which was connected to a smooth four-speed manual transaxle and could produce 282 horsepower at 5,000 rpm and 289 foot-pounds of torque at 4,000 rpm,

The ventilated brake rotors were drilled for increased efficiency, and a large intercooler was housed within the “Tea-tray” rear spoiler. The 1987 930 Turbo, of which 1,695 were built for the U.S. market and another 786 for the “Rest of the World” (RoW), was capable of a near-160 mph top speed.Type 930. 282 bhp, 3,164 cc SOHC horizontally opposed air-cooled six-cylinder engine with a single turbocharger and Bosch electronic fuel injection, Type 930/36 four-speed manual transmission, independent front and rear suspension, and four-wheel ventilated disc brakes.

“Dear Dealer,

In order to ceremonially mark the end of this legendary model and at the initiative of Sonauto, the plant has proposed that we produce a special final series of ten 911 Turbo Coupes. Ten – and no more!”

Towards the end of the production run of the 930, the official importer for Porsche in France, Sonauto, approached the Porsche team and requested a limited edition of cars to mark the swansong of the 930 Turbo in the French market. After a little negotiation the car was signed off, and a very limited run of units with the best possible specifications was commissioned. 10 cars in total were produced. At the time the cost of a new 930 Turbo was FF 614,700. The Sonauto Turbo with its performance kit cost FF 870,000, over 40% more than the standard Turbo.

These cars were hand picked from the production line and reconstructed specifically for Sonauto. The engines were upgraded to “S” specification, producing 330bhp, and breathing through dual twin exhausts. An oil cooler was fitted at the front, as was a front spoiler with ducting for the oil cooler. The suspension was upgraded and lowered, fitted with Bilstein shock absorbers, and the rear track widened by 35mm. As a result of these performance upgrades the Sonauto 930s were capable of a top speed of around 280km/h. The interior was treated to tricolour seats from the Porsche 959, additional instruments, a fitted Pioneer CD player, and a number plaque on the dashboard.

Ten cars were produced in total, eight of which were despatched to owners in Germany, and only two were sent to France. It comes as no surprise to hear that these very final editions of the iconic 930 are highly prized by the world’s most serious Porsche collectors.

The car you see here is number 7 of the 10 made, and has recently come from the collection of a very senior board member of Toyota in Japan. Since being repatriated into Europe, Number 7 has enjoyed an assessment and valuation by Classic Data in Germany. Before coming to Paris the car will also benefit from  a 100 point inspection by Porsche in Dortmund.

Supplied with the German TuV and Fahrzeugbrief, and showing a mere 67,000 recorded kilometres from new, this is an investment grade Porsche of the absolute highest order.
