Dubbed the “Yellowbird” by a group of journalists during a two-day test drive event, the 1987 RUF CTR Yellowbird also earns its name thanks to the canary-like chirping of this twin-turbo’s blow off valve. Just 29 of these cherished classics were built – but you’ll be able to take it out any time in Forza Horizon.

In the late 1980s, Ruf made its auspicious debut in the world of high-performance cars with the original RUF CTR. Nearly a decade later, founder Alois Ruf succeeded in one-upping himself with the CTR2. Like a good Hollywood action sequel, the CTR2 featured more of what fans loved about the original – namely incredible performance, thanks to a 3.6 liter, twin turbocharged flat-six capable of 520 horsepower and a top speed north of 215 mph. As intended, this kind of performance immediately catapulted the CTR2 into the rarefied air of the world’s most elite vehicles, in demand by collectors and speed junkies alike.

Starting with the traditional body-in-white, RUF completely rebuilds or replaces the rest of the componentry, and the result is stunning—730 horsepower and 693 ft-lbs. of torque, enough to rival all but the most extreme supercars. While the R can do things that few cars can equal, it does so precisely and without drama; a skilled driver can use this car as a finely tuned racing tool.

The Ruf RGT-8 has been lightened from nose to tail. To even the strictest of enthusiasts, this is not sacrilege, this is improving on perfection. This Ruf is a true supercar, with an ultra-low center of gravity and off-the-charts speed potential.
