Felix Rosenqvist – Meyer Shank Racing w/Curb Agajanian

2026 Indianapolis 500 presented by Gainbridge winner Felix Rosenqvist hopes to keep truckin’ into Victory Lane this weekend at Portland in yet another special livery featuring an artist and a SiriusXM channel.

The Grateful Dead will be saluted on Rosenqvist’s No. 60 Honda (photo, top). SiriusXM features the legendary jam band on the Grateful Dead Channel (Ch. 23), and the legacy of lead singer and guitar player Jerry Garcia will be honored by “The Days Between,” the annual nine-day celebration between Garcia’s birthday Aug. 1 and the anniversary of his passing Aug. 9.

This all-new livery harkens back to last year’s Grateful Dead design, arguably the most popular of MSR’s SiriusXM music-themed cars last year.
