🇦🇹 Walter Grubmüller

Walter Grubmüller is a retired professional racing driver from Austria. He competed in open-wheel single-seater championships across seven seasons from 2005 to 2012, racing in Formula Renault Eurocup, Formula 3 Macau, and Formula V8 3.5 for teams including P1 Motorsport. His sole podium finish came during his final campaign in Formula V8 3.5.[1]

His career comprised 64 starts across the three series. In Formula Renault Eurocup he ran two seasons as a developing driver in the field; he then contested four Formula 3 Macau rounds. The bulk of his racing came in Formula V8 3.5 between 2010 and 2012, where he started 40 times for P1 Motorsport and finished 13th in the 2012 championship standings with a single podium result.[2]

Throughout his time in Formula V8 3.5, Grubmüller was closely matched with two established professionals: Jake Rosenzweig, a driver with 40 starts in the series alongside experience in GP2 and Formula 3 Euro, and Daniil Move, a Bronze-graded professional who contested 92 rounds in the championship. On occasion he finished ahead of far stronger opposition; he beat Daniel Ricciardo, the 2010 Formula V8 3.5 champion and later a Formula 1 race winner, three times across their meetings, and finished ahead of Nico Hülkenberg twice, though Hülkenberg was champion of Formula 3 Euro and GP2 Series during Grubmüller's racing years.
