Sebastian "Seb" Priaulx (born 18 January 2001) is a British racing driver who competes for Ford Multimatic Motorsports in the IMSA SportsCar Championship.

[10] He continued the season strongly, winning five consecutive races between the rounds at Thruxton and Croft, before parting ways with JHR Developments following their suspension from the series in August.

[14][15] Supported by new sponsor Ravenscroft,[16] his confidence was high entering the opening round at Brands Hatch,[17] and he scored a fourth-place finish in his first race in the championship.

[19] Priaulx's first foray into sports car racing was the 2019 British GT Championship, joining co-driver Scott Maxwell in a Multimatic-prepared Ford Mustang GT4.

[21] It also came amidst changing aspirations for Sebastian, whose focus turned to eventually competing in the 24 Hours of Le Mans as opposed to reaching Formula One.

[22] In the opening round of the season, Priaulx and Maxwell claimed a pair of pole positions, taking the GT4 class victory in the second event of the weekend at Oulton Park.

A second-place result in the final round at Donington Park wasn't enough for the Multimatic team to claim the title, as they fell 7.5 points short of the aforementioned duo of Canning and Hand.

In a partnership between Kelly-Moss Road and Race and Multimatic Motorsports, Priaulx began competing in the new-for-2021 Porsche Carrera Cup North America in its inaugural season.

[33][34] In pre-season testing at Sebring, designed to shake down the new Porsche 992 GT3 Cup car, Priaulx registered the quickest time of the 19 entries that took part.

[46] In July, he joined Inception Racing by Optimum Motorsport's Gold Cup entry in the Spa 24 Hours, driving alongside Brendan Iribe, Ollie Millroy, and Frederik Schandorff.

[49] For the 2023 IMSA SportsCar Championship, Priaulx joined AO Racing Team for their full-season GTD class entry, driving alongside P. J.

Despite leading the GTD Pro championship with four races remaining, Priaulx parted ways with the team mid-season owing to his increasing commitments with Multimatic Motorsports.
