Ford drivers are running the new FR9 engines. Kasey Kahne, who drives for Roush Fenway affiliate Richard Petty Motorsports, blew his engine at New Hampshire. Biffle's problem at Chicagoland was different—but equally terminal.
Clearly, there are bugs that have to be addressed, and that gives Edwards pause.
“I've been taking for granted that our engines run so well and don't have any trouble,” he said. “We can't have that trouble if we want to make the Chase.”
Despite the engine issues, however, Saturday's race was the most positive sign of progress the Roush drivers have seen this season.
“We're definitely on the event horizon,” Edwards said. “We haven't quite crossed over.
“I know we can run that well. We just have to figure out how to do that every week. I hope this is something that we can go back, talk about on Monday, figure out why our car was so much different this week than it has been, and maybe apply it.
“We have some mile-and-a-halfs and tracks like this coming up the rest of the season that are going to be really important tracks.”
With seven races left before the Chase field is set, we'll soon know whether the performance at Chicagoland was a one-night reprieve or the start of something big.
