Before producing the alarmingly quick CTR Yellowbird, RUF was offering upgraded models of the Porsche 911. One of those models, built from 1983-'89, was the 930-based BTR, like this example available from RM Sotheby’s.

The centerpiece of the BTR was its engine: Displacement was increased to 3.4-liters and the turbocharger was tweaked. These modifications made the RUF good for a total of over 370 horsepower—roughly 20 extra ponies over the “normal” 911 Turbo.

The modifications didn’t end there, however, as RUF added a five-speed manual transmission—which it developed in-house—with this specific BTR receiving cruise control and a security system.

This 1981 RUF BTR, accompanied by a RUF letter and invoice, service invoices dating back to 1988, and a Porsche Certificate of Authenticity, is available from RM Sotheby’s through its upcoming Open Roads, April auction.
