Four-time Indycar champion Scott Dixon thinks the series' move to a universal aerokit will hurt Chevrolet more than Honda.
Dixon was the best-placed Honda last year, finishing third in the championship and the Kiwi believes the advantage his rivals had has been removed this year.
"The spread [of team performance] is smaller than it used to be," he told Autosport. "But I think at the start of the season, you're going to see a lot more teams hitting it right to start with.
"The tough one will be [the last test at] Sebring, because everyone has been there and it's extremely grippy, we're doing faster laps than we were with the downforce on it. When we get to St Pete it's going to be a big reality check for people.
"And with an even field now with the aerokit, the competition to Honda last year had a very big advantage on the high-downforce circuits: i.e. road courses and street courses and short ovals.
"So it's definitely going to be a shift that will hurt them more than Honda."
The season opens on the streets of St Petersburg, Florida on March 11.
