[1][2] After making his single-seater debut at the back end of 2016, scoring a podium in the V de V Challenge Monoplace, Neubauer took part in the Toyota Racing Series during the winter of the following year.

His main campaign during 2017 would lie in the Formula Renault Eurocup, where Neubauer partnered Gabriel Aubry, Thomas Maxwell and Max Fewtrell at Tech 1 Racing.

In 2019, Neubauer made a switch to sportscar racing, partnering Nico Bastian in the Silver category of the Blancpain GT Series Sprint Cup with AKKA ASP,[7][8] whilst also competing in the Ferrari Challenge Europe for the Charles Pozzi – Courage operation.

[11] In the former, a sole podium at the final round in Le Castellet ended up being the highlight of a season that concluded with Neubauer, Timothé Buret and Aurélien Panis taking eighth in the Silver Cup classification.

[16] The Ferrari Challenge Europe, where Neubauer once again drove for the team bearing the name of Charles Pozzi, would yield just three podiums, with the French driver competing in three out of seven rounds.

[17] In addition, Neubauer made his debut in the 24 Hours of Le Mans, racing a Ferrari 488 GTE Evo in the LMGTE Am category for JMW Motorsport.

[27][28] Neubauer and the team managed to put together a mistake-free race during the crowning jewel of the calendar, the 24 Hours of Spa, which earned them the Silver Cup win, which the Frenchman called his "most beautiful victory".
