Honda-powered IndyCar teams make late turbo switches at Long Beach

Honda-powered IndyCar teams were forced to make late changes to their turbo units at Long Beach on Friday.

The Japanese manufacturer, which uses a single turbo layout as opposed to the twin-turbo systems deployed by rivals Chevrolet and Lotus, had brought an update to Long Beach with the aim of addressing a reported deficiency in throttle response.

However AUTOSPORT understands that at least one rival manufacturer has protested the system, forcing Honda to revert to its previous specification for the weekend.

IndyCar vice-president of technology Will Phillips said that the series was working to find a solution.

"It's something we're working on now to resolve," he said. "I'm still working on it so I don't want to comment too much on it. We're just pulling the facts together now, and then we'll get back with the manufacturers and sort it out."

Phillips has confirmed that the units will not be changed again this weekend, meaning that the earliest that Honda can hope to run its new system is at Sao Paulo later this month.
