Although they were an American-based effort, spearheaded by Alan Mertens (galmerinc.com), the cars were actually assembled at the Galmer Engineering shop in Bicester, England.

The chassis' most notable accomplishment was Al Unser Jr.'s win at the 1992 Indianapolis 500 in the closest finish in race history.

[1] Galmer attempted to enter Formula One in 1993 with a takeover of the defunct Brabham team, however the effort failed as a result of financial problems.

Due to the proximity of the transponder, Unser Jr.'s official race-winning margin of 0.043 seconds over Scott Goodyear in the 1992 Indianapolis 500 was deemed inconclusive.

[5] After the 1992 season was over, Valvoline purchased the race-winning Galmer chassis driven by Unser Jr. On frequent occasions, it is used for display at various engagements.
