McLaren is pressing ahead with plans to run a full-time IndyCar team in 2019 and will meet with potential partners at this weekend's Dual in Detroit.
Although the plans are very much in the early stages, it will be the second such visit in as many months for McLaren CEO Zak Brown, who will be joined by McLaren advisor and 2003 Indianapolis 500 winner Gil de Ferran.
"Gil and I and a few more McLaren people will be in Detroit meetings," Brown confirmed to RACER.
Though Brown insisted they wouldn't rush into making a decision, adding: "No decision this weekend and no firm timeline."
It comes after McLaren partnered with Andretti Autosport for the 2017 Indy 500, which saw Fernando Alonso skip the Monaco Grand Prix to compete in IndyCar's halo event. The Spaniard qualified fifth and led the race at multiple points before retiring with an engine failure.
That deal was made possible by Honda, with whom McLaren's F1 team was partnered with at the time. However the two companies split last year, with McLaren now running Renault engines. That means the possibility of running a Chevrolet engine is a possibility, though Honda-powered Andretti remains the favourite for McLaren.
