Mueller Blames Early Errors for Seven x Seven's Lost GT300 Title Bid

Sven Mueller came within six points of a GT300 title that looked far off at the start of the year. Two second-place finishes at Motegi put him in the fight, but he's clear about where he thinks it slipped. In his view, the title was lost weeks earlier, through errors that left too much ground to make up before the final round.

A Final Race That Almost Went His Way

Sharing the No. 666 Porsche 911 GT3 R Evo with Taichi Watarai, Mueller took the net lead during the closing 250km race on Sunday. That was the scenario Seven x Seven needed. Had the Kondo Racing Nissan pairing of Joao Paulo de Oliveira and Iori Kimura failed to finish fourth or better, the team would have been champion.

De Oliveira and Kimura did finish fourth, which was enough for them. Mueller then lost the lead in the closing stages to Daniil Kvyat in the JLOC Lamborghini, leaving him second in the standings with a six-point deficit. Those two runner-up results at Motegi are the best of the team's season, which is a strong return for a second-year outfit. It just wasn't quite the return it needed.

The Errors That Added Up

Here's the thing: a six-point gap feels small after a final-round finish, but it's the accumulation that matters. Mueller pointed to a disqualification at Autopolis, where the team lost a runner-up result for failing to complete both mandatory refuelling stops. He also cited a drive-through penalty at Suzuka for track limits abuse. Individually, these are the kind of mistakes that happen in a demanding season. Together, they built a deficit that a single strong weekend couldn't close.

"We had some setbacks, like being disqualified at Autopolis, which probably cost us the championship," Mueller said. "We were not as consistent as we should have been."

That consistency point is the one that stands out. In a points-based title fight, a driver rarely loses the championship on one afternoon. It usually comes down to whether the team banked points in every round, especially the ones where the car wasn't at its best.

Pace, Strategy and a Hard Pill to Swallow

Mueller was candid about the car's raw speed. He described the pure qualifying pace as sitting around P10 to P12, which is well short of what's needed to win from the front. The results at Motegi came from strategy and execution, not from outright speed. Pit stop timing and tire management kept the Porsche in contention, and Mueller credited that combination for putting the car at the front.

That kind of race-day performance is valuable, but it's also fragile. When a rival simply has more pace, as Mueller felt Kvyat did at the end, there's not much a strategy can do. "The speed difference was way too much, and other cars were significantly faster," he said.

Kvyat's winning move drew a pointed comment from Mueller, who noted that the pass around the outside of Turn 4 was made with all four wheels off the track. He framed it as a difference in how things are done in Japan compared with Europe, where he said that kind of move isn't allowed. He didn't dwell on it, though. He acknowledged that the Lamborghini was quicker over the final stint, and that he wasn't certain he could have held the position regardless.

The Lamborghini had a notable edge in the closing phase. Kvyat and co-driver Takashi Kogure had briefly lost the lead during the pit stop phase, changing two tires while the Seven x Seven Porsche stayed out. Mueller said his side kept about a ten-second gap for a period before the Lamborghini picked up the pace sharply. "I was consistently on the limit, pushing like crazy," he recalled.

What Comes Next for Seven x Seven

Mueller's future with the team is still open. He said he needs to finalise his plans with Porsche before deciding which programme he can run next season, and he didn't commit to a 2027 seat. Porsche Supercup runner-up Robert de Haan has been linked to Seven x Seven, which suggests the team is already looking at its driver line-up.

Whatever happens, Mueller's first SUPER GT campaign since 2018 clearly left a positive impression on him. He spoke warmly about working with team director Matt Harvey, Watarai, co-driver Kiyoto Fujinami for the first three races, and the engineers. "It was a fun year," he said.

For a team that came close enough to taste a title, the lesson is less about one lost race and more about the early rounds. The gap to the top was built over the season, and that's the part Seven x Seven will have to fix if it wants to be in this position again. A team that can match its Motegi strategy from the start of the year, without the penalties and mandatory-stop errors, would be a serious threat in GT300 next season.
