Ruf didn’t begin with Porsche’s prime canine to create the Yellowbird. As a substitute of the 930-generation 911 Turbo, Ruf opted for the 911 Carerra 3.2 as its place to begin as a result of it was a lighter automotive. That left a manufacturing facility turbocharger out of the equation, and Ruf started working enhancing a lot of the 911 that the corporate certified in Germany as a producer reasonably than only a tuner.
Every CTR (a reputation derived from Group C Turbo Ruf) began out as a manufacturing facility 911 3.2 that Ruf purchased from Porsche. To chop weight, Ruf changed the doorways, engine cowl, and frunk with aluminum parts and altered the entrance and rear bumpers to fiberglass.

The curb weight, beneath 2,600 lb, gave the automotive a power-to-weight ratio that rivals right this moment’s 911s. How detail-obsessed was Ruf with its Yellowbird? It deemed the then-current 5-speed wasn’t adequate and created its personal beefier 5-speed, partially to deal with the ability and partially to design the gear ratios.
The suspension additionally acquired an improve, and a roll cage added structural stiffness. The brakes had been swapped out for 13.0-inch Brembos, and the automotive wore bigger Speedline wheels and Dunlop tires.
The entire work translated to a world-beating, however little-known supercar. Highway & Observe examined the automotive at Volkswagen’s 15.5-mile Ehra-Lessien analysis oval in Germany within the spring of 1987 as a part of the journal’s “World’s Quickest Vehicles” function.

The CTR emerged because the victor in opposition to the likes of the Porsche 959, Ferrari Testarossa, Lamborghini Countach, and Mercedes AMG Hammer. R&T editors famous the automotive regarded like a yellow chook dashing throughout the horizon.

The underdog journal win, teamed with a raucous video referred to as “Faszination on the Nürburgring” that confirmed take a look at driver Stefan Roser sliding the automotive across the Nürburgring, made the Yellowbird the stuff of goals for a technology of younger automotive fans. The automotive has even appeared in a number of video video games, together with the “Forza” and “Gran Turismo” franchises.
Ruf constructed solely 29 CTRs from factory-fresh 911s, and 20-30 extra had been transformed from buyer automobiles.
