Andretti Autosport will continue to run Honda engines in the 2018 Verizon IndyCar Series despite looking into a switch to Chevrolet.
Andretti has run Honda powerplants since 2014 but considered a return to Chevrolet when it notched up just a single win in 2016, when Alexander Rossi took out the Indianapolis 500.
However, the team has now signed a “multi-year agreement” with Honda.
“It’s no secret that we’ve been weighing this decision for a while now,” said team principal Michael Andretti at the team’s reveal.
“We’ve had strong relationships and have marked milestones with both manufacturers, but we’re pleased to continue our Honda partnership.
“We have a great history of success with Honda and I have no doubt that together, our collection of achievements will continue to grow.”
Andretti has won 47 races with Honda power, and its continuation will likely inform the team’s decision on its 2018 driver line-up.
Reigning Indy 500 winner Takuma Sato is rumoured to be leaving for fellow Honda runner Rahal Letterman Racing, while Rossi is considering his options.
The Honda announcement may help Andretti retain Rossi, while 2012 IndyCar champion Ryan Hunter-Reay and Marco Andretti are contracted for 2018.
