Some engineers might back down from a challenge. The engine designers at RUF don’t quit quite as easily. At the Goodwood Festival of Speed, CarBuzz got up and close with its latest project — an eight-cylinder boxer engine that produces crazy performance figures and a sound unlike any other. While other Porsche-based tuners, restomodders, and coachbuilders simply take an old engine and modify it, RUF is actively building something that we haven’t seen on the road before.
