Charles Dawson and Kiern Jewiss secured the 2025 Intelligent Money British GT Championship GT3 drivers’ crown at Donington Park, as Barwell Motorsport scored a commanding one-two finish in the season finale. In GT4, Jack Brown became the first two-time class champion after sealing the title with a decisive late move in a race shaped by mixed weather and strategy.
GT3: Barwell Dominates as Dawson and Jewiss Do Enough
Despite not finishing on the podium, Dawson and Jewiss claimed the GT3 title thanks to their sizeable 28.5-point lead heading into the #DoningtonDecider. A fourth-place finish in tricky conditions was enough to secure the championship after their main rivals failed to deliver the required race-winning result.
Barwell’s Lamborghinis were in a class of their own throughout the two-hour contest. Rob Collard held the lead early on in the #1 Huracán before Alex Martin closed the gap in the sister #78 car. Both pitted together mid-race, with the #1’s Compensation Time allowing Martin and Sandy Mitchell to move ahead. From there, Mitchell pulled clear to record his and Martin’s first win of the season by 31 seconds.
Collard and Hugo Cook completed a Barwell one-two to leap from fifth to second in the final drivers’ standings. Kevin Tse and Maximilian Götz finished third on the road and in the championship.
Dawson’s opening stint was eventful in damp conditions. After climbing to third, he was involved in contact with Giacomo Petrobelli at Old Hairpin and later tapped Morgan Tillbrook into a spin at Coppice. The latter incident resulted in a 10-second penalty during the pitstop, added to the maximum Compensation Time earned for their previous Brands Hatch win.
Tillbrook’s retirement, Petrobelli’s delay, and strategic gambles that backfired for other contenders effectively neutralised the title fight. Blackthorn’s Jonny Adam switched to wets during the heaviest rain, but when conditions improved, a second stop dropped the Aston Martin to 11th.
Jewiss brought the 2 Seas Mercedes-AMG home in fourth, sealing the title comfortably. Blackthorn’s guest entry of Darren Leung and Nick Yelloly finished fifth, while Beechdean’s Andrew Howard and Tom Wood won Silver-Am and placed sixth overall. The Spirit of Race Ferrari and Orange/JMH McLaren rounded out the top eight.
GT4: Brown Seals Title with Late Pass
In GT4, Jack Brown and Marc Warren overturned a points deficit to win the drivers’ championship in dramatic fashion. Brown’s decisive pass in the closing stages not only secured the race win but also made him the class’s first two-time champion and most successful driver with 13 victories.
Century Motorsport’s BMW, driven by Ravi Ramyead and Charlie Robertson, initially held the upper hand after qualifying three places ahead of Optimum’s McLaren. Both title rivals ran nose-to-tail for much of the race, but Century’s additional Compensation Time proved crucial during the pitstop cycle. Warren handed over to Brown, who rejoined in the lead after a clean stop.
The Mahiki Racing Ginetta of Luke Garlick and Blake Angliss emerged as a surprise threat. Garlick led early from pole but suffered a puncture after clipping a tyre stack. Repairs under Safety Car kept the car on the lead lap, and Angliss charged back to the front after the rain arrived with 40 minutes to go.
On slicks, Brown temporarily lost the lead to Angliss as Robertson closed in. But as the track dried, Brown retook control with a move into the Melbourne Loop, securing both the race and the title. Angliss and Garlick finished second, while Harry George and Luca Hopkinson snatched third from Robertson by just 0.026s to complete a one-three result for Optimum.
Optimum retained the GT4 Teams’ title, with Hopkinson and George also claiming the Silver class crown. Ramyead and Robertson were fourth, while Ed McDermott and Seb Morris sealed the Endurance Cup with fifth in class. Mahiki received British GT’s Team of the Weekend Award for repairing its Ginetta after a heavy Friday crash.
Titles Decided
Dawson and Jewiss’s championship capped a season defined by consistency and smart racecraft, while Brown’s historic GT4 triumph confirmed his status as the benchmark driver in the category. The Donington finale delivered a fitting conclusion to another competitive British GT season, with changing conditions, strategy, and pressure all playing decisive roles.
