RUF's Porsche CTR 3 - Exactly 20 years after the legendary CTR "Yellowbird" and 10 years after the second CTR, RUF announces the all-new CTR 3. The concept of this classic sports car came from Alois Ruf. The CTR 3's twin-turbocharged 3.8 litre flat-six cylinder engine has an output of 750 HP at 7,100 rpm. The maximum torque is 708 ft/lbs at 4,000 rpm. The CTR 3's performance is incredible. Acceleration from 0 to 60 mph takes only 3.2 seconds, and its maximum speed is 236 mph!
