[8] Driving alongside Filipe Albuquerque and Phil Hanson at United Autosports, Scherer began the year with a win during his debut at Spa-Francorchamps before having to miss the next round due to COVID-19.

Having joined Inter Europol Competition ahead of the 2022 season, the Swiss driver made a one-off appearance in the WEC to replace a COVID-stricken Alex Brundle before embarking on a campaign in the ELMS, where he would be partnered by Pietro Fittipaldi and David Heinemeier Hansson.

[16] The Swiss driver remained at Inter Europol the following year, returning to the WEC on a full-time basis alongside Albert Costa and Jakub Śmiechowski.

[17] The trio scored points in all seven races, even taking a podium at Spa, though the highlight of the season, as well as a personal success story for Scherer, turned out to come at Le Mans: during Scherer's first pit stop the Corvette Racing car drove over his left foot after he had exited the car, resulting in an incomplete fracture and ligament damage.

[18] In spite of the pain, Scherer continued driving throughout the 24-hour event, even passing the WRT of Robert Kubica during the morning and holding on against a late charge from Louis Delétraz to cross the line first despite radio issues inside the final hour.
