Latest on the Ford FR9 engine

Ford's FR9 engine, run sparingly since its debut last season, will likely be in use by all Roush Fenway Racing and Richard Petty Motorsports teams by midsummer, according to Roush Fenway Racing team co-owner Jack Roush. "We're going to run the engines in all the cars at Charlotte for the All-Star weekend," Roush said Saturday at Dover International Speedway. "By Michigan, I don't know that we will have the engine in all the Ford cars from that point forward, but we will at least have half a dozen engines in the 10 or so Fords that we build engines for. From that point on, depending on the durability and depending on the confidence, depending on the supply of parts, we'll have that available to us." Teams began phasing in the new engine late last season as a replacement for the 452 model. An abundance of the existing engines and lack of new pieces for the FR9, as well as durability questions, kept Ford teams from making the switch en masse. "It's been Doug Yates' determination, and my determination and all the people that are under his management, that we didn't want to introduce the engine as long as there was a known problem and until there were enough parts to make a satisfactory representation," Roush said. Yates heads up Roush Yates Engines, which supplies the Ford power. SceneDaily
