RUF BTR

This genuine W09 RUF BTR is finished in the classic combination of Guards Red over a Black leather interior. It was initially imported to the U.S. in March 1987 and was consigned to the EPA, which shipped it to their headquarters in Ann Arbor, Michigan to undergo emissions certification on behalf of the RUF Automobile. After its time achieving “blanket certification” from the EPA in July 1987, copies of its original Bill of Sale record that it was sold new on 6 February 1988 to its first owner, Frederick Sontag of Roscoe, Illinois. In fact, Sontag had been corresponding with Alois Ruf from October of the previous year and, due to his fastidious nature, the history file is full of important records that include its Certificate of Origin, RUF Limited Warranty paperwork, model specification sheets, registration correspondence with the State of Illinois, and, perhaps most fascinating, scans of the EPA Certificate of Conformity for the car dated July 1987.

Its clean CARFAX Vehicle History Report shows that this example was then registered in Oklahoma in June 2003. The Louisiana-based consignor purchased this RUF in June 2011 from RUF Auto Centre in Dallas, Texas and immediately began a restoration of the BTR’s mechanicals and interior to near-factory correct specifications. This comprehensive restoration was begun by Eagle Racing in Dripping Springs, Texas and included a transmission refurbishment, a complete brake overhaul, Retro Air R134 A/C update, and more. In 2019, the motor went through a rebuild by Protomotive including new pistons, cylinders, and Carrillo connecting rods. The owner also sourced and installed a correct type RUF BTR turbocharger and RUF four-pipe exhaust.

Interior preservation was prioritized: the Blaupunkt Monterey SQR 23 radio, RUF-branded carpets, and restored Recaro seats remain. The “Ladedruck” turbo boost controller has been intentionally disconnected; wisely keeping in check the level of thrust best reserved for Le Mans heroes, not mortal hands. The boost is set at factory specification of 0.825 Bar. Since its thorough renewal, this example has been driven frequently by the consignor and consistently maintained by a full-time in-house mechanic and has recently received a fresh oil change and new tires.

This RUF BTR 3.4 is offered with its impressive history file and a substantial set of Eagle Racing and Protomotive invoices. As an exceptionally rare factory W09 Slantnose with an extraordinary trove of factory, federal, and original owner documentation, this 1987 RUF BTR carries provenance matched by few of its peers. It offers the best of both worlds: a thoroughly engaging driver’s car meant to be enjoyed on the road, paired with an extensive, documented history that elevates its desirability and collector significance. Enhanced with a meticulous, authenticity-driven restoration under its most recent caretaker, it is a compelling addition to any serious RUF or Porsche collection.
