Alexander Rossi: I had one of the best racecars I'd ever driven

Andretti Autosport's Alexander Rossi believes the #27 NAPA-Honda was one of the best racecars he has ever driven after taking a dominant win at the REV Group Grand Prix at Road America.

Rossi started second after being beaten to pole by 19-year old Colton Herta in the #88 Andretti-supported Harding Steinbrenner Racing entry, but he was able to pass the rookie around the outside of Turn 1 and was able to gap the field at over half a second a lap for the majority of the race.

"It was probably one of the best racecars I've ever had," said Rossi. "Huge hats off to the 27 team, (engineer) Jeremy (Miles) and (strategist) Rob (Edwards) and the whole group of guys.

"I mean, we have been quick through the whole season. But, yeah, we just haven't really had it come our ways many times as we want for one reason or another.

"It was good to be able to look into things after Texas, kind of understand what was our mistakes, what was bad luck, and the source of it. To come out and be able to do what we did today is a huge testament to the whole organization."

The Californian put a lot of emphasis on his team being able to give him the car to put on such a dominant display as they continue to find improvements as the season goes on.

"I told the guys on the radio, once I crossed the chequered flag, it was the best car I've ever driven. I think there's a lot of truth to that," he added.

"I don't care how well you're driving, what sort of talent level you're perceived to have, you can't do anything without a car underneath you.

"The Andretti Autosport group I think was strong all weekend. Ryan had some bad luck in qualifying, otherwise, he would have been right up there, as well.

"This is something that each weekend we're trying to improve upon our weak areas. We're able to continue to chip away at it."
