THIS RUF BTR II CABRIOLET WILL BE SOLD IN AN ONLINE AUCTION WITH OUR FRIENDS AT BRING-A-TRAILER. I WILL UPDATE THIS LISTING WHEN THE AUCTION GOES LIVE.

RUF Automobile was founded in Pfaffenhausen, Germany in 1939, by Alois Ruf Sr. Initially it was known as “AUTO RUF” and then later under the name RUF Automobile after ownership passed to Alois Ruf Jr.

RUF had been involved in numerous projects for the latter half of a century but became most famous for their aftermarket, highly tuned Porsche Turbos. In 1983, RUF was granted a constructors agreement by the German Government and assigned his own unique VIN numbers. He had for many years been providing clients with donor 930 Turbos a variety of tuning and appearance items but by 1983, he also offered select clients a complete version of the 930 Turbo known as the BTR II.

Actual production records are not known but most believe he tuned upwards of 50 to 70 client provided donor 930 Turbos while select clients had in-house examples completed from new. Of this no more than 30 were completed and this particular BTR II is one of two known Cabriolets so completed.

The BTR II was powered by a highly tuned 3.4-liter, air-cooled, flat six derived from the engine case of the 930 Turbo. RUF however used all of his own internals, including crank, rods, valves, cams and pistons of his own design. Better airflow, ignition, cam timing and a massive intercooler provided for 369bhp over the stock 300 from Porsche.

Rather than using Porsche's highly unpopular and rather dated four-speed, RUF BTR II's used their own unique five-speed units with limited slip differentials. A combined set of three oil coolers with a large prominent one in the front apron provided sufficient cooling for the “hot” engine set up of this new RUF. An equally impressive, free-flowing, quad tip exhausts system further improved performance which by all measures of the time was just outstanding!

Numerous body modifications, badging and light alloy rims complemented the interior which had special seats, gauges and further detailing throughout.
From Alois Ruf's individual records for this vehicle, we have the following details:
