Porsche's model rests on selling low-volume, high-margin sports cars (911) alongside higher-volume SUVs (Cayenne, Macan) that share expensive platform engineering with Volkswagen Group siblings like Audi to cut R&D costs. By 2025, global deliveries were led by Cayenne (about 29% of 279,449 deliveries) and Macan (Porsche's best-selling line), with 911 at about 19%, Panamera about 10%, and the all-electric Taycan just 6% -- a sign of how much the sports-EV bet underperformed. That underperformance forced a dramatic 2025 reset: Porsche took an EUR3.9 billion writedown reversing parts of its EV strategy as Taycan deliveries fell 22% and China deliveries -- once a core growth market -- dropped 26% against faster, cheaper domestic Chinese EVs. Combined with a roughly EUR700 million annual liability from US tariffs on vehicles imported from European factories, group operating profit collapsed 92.7% to EUR413 million in 2025 (automotive-division operating profit fell 98%, to just EUR90 million), and net income after tax was EUR310 million, down from EUR3.595 billion in 2024. Porsche is now publicly reversing course, extending combustion-engine models it had planned to retire and shelving EV platforms it had already spent years developing. Porsche's return to combustion-engine investment after the 2025 crisis represents a rare public reversal for an European luxury automaker, and industry analysts have watched closely to see whether rivals like Mercedes-Benz and BMW follow with similar EV-timeline recalibrations.
