If you’re not familiar with the CTR Yellowbird, let me break down the specs of this 1987 classic for you. It features a twin-turbocharged 3.4-liter motor that pushes out 469 horsepower and 408 lbs-ft of torque. Not that impressed? What if I told you it went from 0-60 in 3.7 seconds? I thought so…Jethro Bovingdon, Car and Driver’s European correspondent, takes the fabled 911 Ruf Yellowbird for a spin around the test track, visits the RUF factory, and takes the Ruf CTR 3 on Germany’s autobahn for some high-speed fun.
