In 1998, the production of Porsche 911s with air-cooled flat engines came to an end. The last model, known internally as the 993, marked the end of an era for waterless engine-powered two-door cars.

Porsche enthusiasts who share a deep love for air-cooled engines, tracing back to the original Volkswagen Beetle, are willing to spend a significant amount of money on well-preserved or special edition air-cooled 911s. Recognizing this passion, Ruf, a renowned Porsche specialist and maker of the iconic Yellowbird, has decided to revive the air-cooled flat-six engine in the Ruf Tribute, coinciding with the 60th anniversary of the model.

The Ruf Tribute features a rear-mounted 3.6-liter powerplant, designed by Alois Ruf Jr., the company’s founder. The engine is equipped with twin turbochargers, billet-aluminum heads, four-cam three-valve technology (a first for air-cooled engines according to Ruf), variable valve timing and lift, and a dry-sump oil system.
