Monterey SportsCar Championship delivered one of the most dramatic finishes of the 2026 endurance racing season as Laurin Heinrich snatched victory on the final lap with a fearless overtaking move on Earl Bamber at WeatherTech Raceway Laguna Seca.
Driving the #5 Porsche 963 for JDC-Miller MotorSports alongside Dutch team-mate Tijmen van der Helm, Heinrich completed a relentless late-race pursuit to secure a landmark Grand Touring Prototype (GTP) triumph. The result marked the first overall GTP-era victory for a privateer entrant since the current top-class regulations were introduced, underlining the increasingly competitive nature of the IMSA WeatherTech SportsCar Championship.
The defining moment arrived with only minutes remaining. Heinrich, having steadily erased a multi-second deficit, drew alongside Bamber’s Whelen Cadillac entering Turn 3. The pair ran side-by-side through the sweeping section before Heinrich finally completed the move approaching Turn 5, forcing the Porsche ahead with remarkable commitment and precision. He crossed the line 0.758 seconds clear after an extraordinary duel that brought the California crowd to its feet.
For Heinrich, the win represented the eighth class victory of his IMSA career and his third consecutive triumph at Laguna Seca, although his previous successes had come in the GTD Pro category. For van der Helm, meanwhile, it was a maiden IMSA victory in his 31st start.

The victory also reshaped the championship standings. Heinrich moved into the overall GTP points lead, opening a 21-point advantage over Cadillac driver Jack Aitken. It is an impressive turnaround for JDC-Miller, a customer team competing against heavily backed factory operations from Porsche, Cadillac, Acura and BMW.
The race itself unfolded as a strategic thriller from the outset. Pole-sitter Louis Deletraz led the field away in the #40 Cadillac for Wayne Taylor Racing, initially holding off Aitken’s Whelen Cadillac through the opening phase. The leading pair quickly established a gap while navigating dense GT traffic around the undulating 2.238-mile circuit.
Early drama arrived when Tom Blomqvist was forced off the circuit following contact in Turn 3 aboard the #60 Acura Meyer Shank Racing ARX-06. Although he continued, the incident compromised Acura’s early strategy.
Another setback followed shortly afterwards for the #10 Wayne Taylor Racing Cadillac driven by Filipe Albuquerque. A suspected puncture and subsequent suspension damage forced the car behind the wall, effectively ending its challenge before the first hour had elapsed.
Aitken eventually seized the lead with a bold outside move at the Andretti Hairpin after 25 minutes, brushing lightly against Deletraz as the Cadillac pair battled through slower traffic. Once clear, the Briton rapidly opened a gap of more than three seconds.
The complexion of the race shifted dramatically during the pit-stop cycles. BMW briefly emerged at the front thanks to efficient service, while Porsche Penske Motorsport also entered contention through clever tyre strategy. However, a caution period triggered by Matt Bell stopping his Corvette in Turn 2 compressed the field and intensified the strategic battle.
During the yellow-flag stops, several leading teams encountered costly delays. BMW lost valuable seconds when its two cars interfered with one another in the pit lane, while the #40 Cadillac suffered a wheel attachment issue that required the car to be dropped and raised again.
Those complications handed momentum to Porsche. Felipe Nasr briefly inherited the lead for Porsche Penske Motorsport, but a longer final stint and tyre wear ultimately left the factory Porsche vulnerable.
As fuel strategies diverged in the closing stages, Bamber appeared to have positioned himself perfectly. The New Zealander conserved more energy than several rivals and emerged effectively in control once Blomqvist’s fuel-saving gamble finally unravelled with a late stop.
Yet Heinrich was charging.
Having earlier run wide at the Andretti Hairpin while chasing the leaders, the German recovered superbly during the final stint. Lap after lap, he sliced chunks from Bamber’s advantage, aided by fresher pace and determined traffic management.
With less than five minutes remaining, the gap fell from over two seconds to under one. Two laps later, Heinrich was directly on Bamber’s rear wing. The pair even made slight contact while threading through GT traffic, heightening the tension before the decisive manoeuvre arrived.
The dramatic overtake completed a breakthrough afternoon not only for Heinrich but also for JDC-Miller MotorSports, whose persistence as a customer programme has now been rewarded with one of the most significant victories of the modern IMSA era.
Elsewhere, Frederic Vervisch and Christopher Mies claimed GTD Pro honours for Ford after fuel concerns forced several rivals into late pit stops. In GTD, Trent Hindman and Danny Formal guided the Wayne Taylor Racing Lamborghini to victory after rivals faltered on fuel calculations in the closing minutes.
However, the lasting image from Laguna Seca was Heinrich’s audacious final-lap attack — a move that instantly joined the circuit’s long history of memorable IMSA finishes and firmly established the young German as a genuine title favourite for 2026.
