Ruf Automobile GmbH is a German car manufacturer. Ruf vehicles are derived from unmarked Porsche chassis, specifically known as a Body in white. Through these fundamental platforms, RUF design and engineer its own original vehicles. Considering the cars are built from these bare chassis, and thereby assembled using Ruf-made parts and materials, (e.g. CTR2, RT12), instead of badge engineering, the company is officially recognized as a manufacturer by the German government. As such, all RUF models have certified Ruf VIN and serial numbers, and are recognized as production models, as opposed to modified Porsches. Ruf is historically known for its record breaking 1987 CTR Yellowbird, and is the largest, most renowned company to make Porsche performance enhancements. Though primarily a manufacturer, Ruf has also made a name for itself operating as a car tuner, a specialist in customer-requested Porsche to Ruf conversions (e.g. Turbo R conversions) and as a restorer of classic Porsche and Ruf models. Ruf carries out service and crash repair, as well.
