Mercedes-AMG has strengthened its advantage at the top of the 2026 global GTWC manufacturers’ standings following the latest round of GTWC America at Road America.
The German marque now leads Porsche by 52 points as the worldwide competition enters its decisive stages, while Ferrari remains third and retains an outside opportunity to close the gap. Mercedes-AMG sits on 898 points compared with Porsche’s 846 and Ferrari’s 729.
Mercedes-AMG extends advantage at Road America
GTWC America returned from its summer break at Road America, but the global manufacturers’ competition had continued through events elsewhere during the North American championship’s absence.
Mercedes-AMG entered the Wisconsin weekend already leading the competition and strengthened its position through strong results from its customer teams. TR3 Racing provided the marque’s headline result by taking Pro-Am victory with Brayton Williams and Daniel Morad in the No. 9 Mercedes-AMG GT3 EVO.
Williams and Morad emerged on top following a closely contested three-hour race, earning an important result for both their domestic campaign and Mercedes-AMG’s worldwide manufacturers’ challenge.
JMF Motorsports also contributed with another podium in the Pro category. Michai Stephens and Mikael Grenier brought the No. 34 Mercedes-AMG home on the class podium, adding another useful points haul as the American season heads towards its final two events.
Those results helped Mercedes-AMG move to 898 points globally and preserve its position as the manufacturer the rest of the field must chase.
Porsche remains Mercedes-AMG’s closest challenger
Porsche continues to apply the greatest pressure and sits second on 846 points, leaving only 52 between the leading manufacturers.
Its Road America challenge centred on two Pro-Am podium finishes. RS1 bounced back from a difficult previous round at Road Atlanta as Danny Dyszelski joined the team and helped the No. 28 Porsche secure second in class.
Road Atlanta had ended prematurely for the team following contact, making its return to the podium particularly valuable during the closing stages of the season.
Wright Motorsports completed the Pro-Am top three with Dave Musial Jr. and Ryan Yardley in the No. 31 Porsche. Their third-place finish represented the pairing’s third podium of 2026 and also moved them into the GTWC America Pro-Am championship lead with two rounds remaining.
The customer results kept Porsche firmly within reach of Mercedes-AMG globally, although it must now overturn a deficit of more than 50 points as several GTWC championships approach their conclusions.
Ferrari takes victory but suffers mixed Road America weekend
Ferrari remains third in the global standings on 729 points after experiencing contrasting fortunes at Road America.
Scuderia Corsa produced the manufacturer’s strongest result by winning the Am class on its GTWC America debut. Mitchell Green and Jon Morley took the No. 67 Ferrari 296 GT3 to victory, immediately adding a strong result to Ferrari’s worldwide campaign.
AF Corse USA endured a more difficult race despite showing considerable speed earlier in the weekend. Matias Perez Companc and Miguel Molina had secured pole with the No. 12 Pro Ferrari but suffered a mechanical problem during the race that forced the car behind the wall for repairs.
The No. 163 Am entry of Jay Schreibman and Benny Simonsen also encountered mechanical trouble, preventing Ferrari from maximising the opportunity to close on the two manufacturers ahead.
Ferrari therefore leaves Road America 117 points behind Porsche and 169 behind Mercedes-AMG, although several rounds across the global GTWC platform remain available for it to reduce those deficits.
Global GTWC fight moves to Australia and Europe
The global championship now shifts attention away from North America temporarily, with GTWC Australia and GTWC Europe both returning from 18–20 September.
Sydney will host the next Australian round while the European Sprint Cup continues at Zandvoort on the same weekend. Those two events provide Mercedes-AMG, Porsche and Ferrari with their next opportunities to influence the worldwide manufacturers’ standings.
GTWC America then resumes at Barber Motorsports Park from 25–27 September for the penultimate round of its season. The championship subsequently concludes with the Indianapolis 8 Hour, an event that also carries considerable significance within the broader global fight.
With Mercedes-AMG holding 898 points, Porsche on 846 and Ferrari at 729, the leading trio still have several opportunities to add to their totals. Mercedes-AMG currently controls the contest, but Porsche’s 52-point deficit leaves the championship open as the various regional series enter their final stages.
