When Obsession Meets Engineering: How a Team of Weissach Zealots Forged a Cup Racer That Redefined One-Make Racing

Picture this: a ragged bunch of engineers and drivers holed up at Weissach since mid‑2018, led by Product Manager Christoph Werner, hashing out what the next-gen 992-based cup racer should wield 维基百科+15Porsche Newsroom+15Ultimatecarpage.com+15. They tapped feedback from mechanics, drivers, team bosses – everyone – trying to make this thing faster, tougher, cheaper to run. You can almost hear Werner snarling, “More downforce, more power, fewer breakdowns.” Mission accomplished.

The 4.0‑litre flat‑six, lifted almost wholesale from the GT3 R and RSR, now cranks out a bonkers 375 kW (510 PS) – that’s 25 PS more than before Porsche Newsroom. It revs to 9,000 rpm, thanks to Porsche veteran Thomas Mader, who put the engine through 22,000 hours on dynos and even ran it continuously at 300 km/h on Nardò’s oval Porsche Newsroom+1Porsche Newsroom+1. Pure German obsession.

Aerodynamics were dialled in by Mathias Roll, who oversaw over 700 wind‑tunnel simulations and 160 hours of testing Porsche Newsroom. The result: a swan‑neck rear wing lifted off the underside airflow, four‑position diffuser, 50 % more downforce in stock form and up to 150 % with full track setup NetCarShow.com+10Porsche Newsroom+10Porsche Newsroom+10. The chassis? Wider 12‑inch front, 13‑inch rear rims, turbo‑spec widebody at 1,902 mm – all to stick it to the tarmac like an angry gecko Ultimatecarpage.com+1motorauthority.com+1.

Inside, Cosworth’s Luigi Brasacchio and his crew kitted it out with a 10.3‑inch CDU display, logging diagnostics and telemetry via FlexRay – rare in one-make series Racecar Engineering. Anders Ericsson would be jealous of how clearly your engine temps, gear, and errors are shown mid-race.

The Cup’s debut was electric. In Porsche Carrera Cup North America, lap times dropped by up to 3 seconds on European circuits, pushing performance nearly to GT3 R levels Porsche Carrera Cup North America. It even tackled endurance at Nürburgring NLS like a pro Racecar Engineering+13Porsche Newsroom+13Porsche Carrera Cup North America+13.

This isn’t a road car with stickers; it’s a true motorsport weapon. From Werner’s strategic briefings in 2018 to Roll’s aerodynamic artistry and Mader’s engine endurance torture, Porsche distilled decades of racing DNA. The result? A machine that demands respect – and gobs of skill.
