[10] van Berlo returned to the LMP3 class of the European Le Mans Series, rejoining United Autosports alongside Jim McGuire and Andrew Bentley.

[12] In parallel to his ELMS campaign, van Berlo also raced in the endurance rounds of the IMSA SportsCar Championship with Riley Motorsports.

[26] Staying in the IMSA SportsCar Championship, van Berlo joined Kelly-Moss with Riley for his first full season in the GTD category.

[27] The Dutchman's first GTD win came at Laguna Seca,[28] but the full-season plans were derailed when teammate Alan Metni suffered a non-racing related injury and the car was withdrawn from that year's Petit Le Mans.

[29] Alongside his IMSA commitments, van Berlo joined the GT4 America Series, partnering Curt Swearingin at ACI Motorsports.
