PREVIEW: 2025 British GT Championship - Oulton Park

British GT returns to Oulton Park for a crucial double-header as the 2025 season heats up.

This bank holiday weekend, the British GT Championship heads to Oulton Park for rounds three and four, promising action across the GT3 and GT4 classes this weekend. For fans of German manufacturers—Porsche, BMW, Mercedes-AMG, and Audi—there is plenty to watch as the title battles start to take shape.

Porsche: Müller’s Experience Under the Microscope

Team Parker Racing arrives with the #66 Porsche 911 GT3 R (992), driven by Nick Jones and Sven Müller. The season started on a difficult note, with a heavy incident at Donington dropping the pair to 22nd. There was progress at Although he is racing at Oulton Park for the first time, Müller’s record in GT World Challenge Europe and at the Nürburgring should give confidence, finishing 15th, but the team is yet to find the pace to fight at the front.

This is Parker’s first full campaign with the 992-generation car. Sven Müller, a seasoned Porsche factory driver, is helping to accelerate the team’s learning curve. Although he is racing at Oulton Park for the first time, Müller’s record in GT World Challenge Europe and at the Nürburgring should give him confidence.

Müller told Dailysportscar.com: ‘We were a little bit unlucky [at Donington]. But we know this car well and hope for a better result… if we do a good job, a podium is possible.’ He is clear about the challenge: these tight, technical British circuits are new for him, and getting the Porsche set up for them takes patience and precision.

One note for the season: Müller will miss the Spa round due to Nürburgring 24 Hours commitments. Harry King is set to stand in, a story to watch later in the year.

BMW: Century’s Consistency in Both GT3 and GT4

Century Motorsport is BMW’s headline act. The team runs a BMW M4 GT3 Evo for Jon Kearney and Will Moore in the Silver-Am class. While the GT3 car is still finding its feet in the ultra-competitive field, it is the GT4 programme that is turning heads.

• The #71 BMW M4 GT4 Evo (Ravi Ramyead and Charlie Robertson) is tied for the GT4 Pro-Am lead, with a win at Silverstone and a strong second at Donington.
• The #14 car (Branden Templeton and Chris Salked) leads the GT4 Silver class and sits third in the overall GT4 standings, although they must serve extra pitstop time in Race 1 after their Silverstone podium.

Century is known for careful setup work, and the front-engined M4 platform is competitive against its mid-engined rivals. There are no major technical changes for Oulton, but small refinements could be decisive as the weather and track conditions change.

Mercedes-AMG: 2 Seas Lead the Way

2 Seas Motorsport has set the pace so far, with the #42 Mercedes-AMG GT3 Evo (Charles Dawson and Kiern Jewiss) topping the GT3 championship after winning Donington and second place at Silverstone. They will carry 25kg of success ballast into Oulton Park, which could make things interesting, especially on a circuit where overtaking is tricky.

The sister #18 car (Kevin Tse and Maximilian Götz) is also in the mix, fourth in the standings. Team Abba Racing (Richard and Sam Neary) provides another Mercedes-AMG threat, which is always popular with fans.

In GT4, Team Parker Racing runs the #30 Mercedes-AMG GT4 for Jon Currie and British GT veteran Phil Keen. Keen’s record at Oulton is impressive, with six previous GT3 wins. They are third in the GT4 Pro-Am standings and could be a factor this weekend.

Worth remembering: the outright GT3 lap record at Oulton Park (1:33.857) was set by Jules Gounon in a Mercedes-AMG in 2022.

Audi: Steller Chasing Another Upset

Audi’s 2025 effort comes from Steller Motorsport, running an Audi R8 LMS Evo II in the Silver-Am class for Darren Burke and Matt Topham. They took a class win (ninth overall) at Silverstone, showing they can punch above their weight.

Audi’s history at Oulton Park is strong in both GT3 and GT4. The current GT4 lap record (1:43.059) was set here in 2022 by Sennan Fielding in a Steller-run Audi R8 LMS GT4.

Hugo Cook, an Audi regular in 2024, has switched to another manufacturer this year, but Steller’s continued involvement means Audi fans still have a car to cheer for.

What to Watch For

• Can Team Parker Racing make a breakthrough with the Porsche 911 GT3 R? Sven Müller’s experience is vital as the team targets their first top ten and possibly more.
• Will BMW’s GT4 stars hold their advantage? Century Motorsport looks strong in Pro-Am and Silver classes, but extra pitstop time could open the door for rivals.
• Can 2 Seas Motorsport handle the ballast and keep their lead? Mercedes-AMG has dominated so far, but Oulton Park is never straightforward.
• Are Steller and Audi capable of another surprise? Class wins are possible, especially if rain mixes up the order.
