In 2005, Luyendyk attempted to make his IndyCar Series debut by qualifying for the 2005 Indianapolis 500 in a car owned by Curb-Agajanian/Beck Motorsports. Luyendyk's qualifying speed of 215.039 mph (346.072 km/h) was close to 2 mph (3.2 km/h) slower than the next slowest qualifier at the time. A. J. Foyt hired driver Felipe Giaffone to qualify a third car for him, and Giaffone's 217.645 mph (350.266 km/h) four-lap average bumped Luyendyk from the field.

Luyendyk did qualify for the 2006 Indianapolis 500 in a car owned by his father and backed by cheapcaribbean.com and Blue Star Jets. The team had limited practice time due to a second week engine program. However, his first race in the more powerful cars ended early due to handling issues, with Luyendyk finishing 54 laps out of 200 and ending in 28th place in the field of 33. ^{[citation needed]}
