Manthey Claims Magic Mapping After Controversial DTM Finale Drama

Manthey Racing accuses BMW of ‘magic mapping’ during the DTM finale at Hockenheim, after Rene Rast loses the 2025 title in a clash with champion Ayhancan Guven. BMW denies wrongdoing.

The suspicion mirrors Nürburgring claims earlier this year, with rivals reporting the BMW M4 GT3 Evo showing intermittent power surges. Abt later supports the allegation after Hockenheim.

Race control and post-event checks find no irregularities. Without torque sensors, verifying power delivery in DTM remains difficult, leaving teams to argue from lap-time patterns and video.

BMW’s Andreas Roos criticizes Guven’s late-braking move at the hairpin. He says it unsettles Rast and triggers the contact that ends BMW’s title bid.

Roos accepts the multi-car title fight adds drama, yet calls the clash unrepresentative of the standards expected in a championship decider.

Manthey’s Nicolas Raeder counters by highlighting BMW acceleration out of key corners. He references Nürburgring examples and insists Guven manages the outside line cleanly against Rast.

Raeder avoids specifics yet questions the acceleration traces. He contends Rast ‘would have won easily’ with equal performance, and argues BMW’s behaviour warrants scrutiny.

Porsche’s Kevin Estre reports ‘very strange power distribution’ at the Nürburgring 24 Hours. He cites Rowe’s BMW blasting past the Grello Porsche along Dottinger Höhe.

Daniel Abt echoes the suspicion after Hockenheim. He describes situational engine maps manipulating output, potentially undermining the Balance of Performance framework that governs DTM parity.

Abt links that to Marco Wittmann’s surge from 17th to second, calling BMW’s pace ‘frightening’ at stages.

Countering that, officials release data showing no Guven error. Rast approaches the hairpin 6 km/h faster, with that speed gap broadly constant across the race.

TV footage shows Gilles Magnus ahead by several lengths before the hairpin. Aston Martin enjoys favourable Hockenheim BoP, complicating straightforward straight-line comparisons.

Despite ballast and a smaller restrictor, Guven sets fastest lap at 1:37.529. Wittmann’s combined sectors yield a 1:37.357 theoretical best, underlining BMW’s underlying pace.

Stewards clear the cars after inspection. The absence of torque sensors prevents a conclusive audit of delivered power, sustaining skepticism on both sides.

The finale ends with trust strained. Teams leave Hockenheim debating mapping, responsibility, and racecraft, while the BoP framework invites renewed scrutiny into the off-season.
