McLaren Shares Intriguing Theory on F1 Power Units — Is Spa's Challenge Gone in 2026?

Theory Briefing

• McLaren's paddock theory holds that the 2026 F1 power unit regulations could eliminate Spa-Francorchamps' traditional engine-stress advantage.
• Spa has long punished teams with weaker power units due to its long, flat-out straights — a dynamic that may not survive the 2026 rule overhaul.
• The 2026 regulations remain a central talking point in the paddock, with teams still debating how the new power unit formula reshapes circuit-by-circuit competitiveness.
• If Spa's power-unit premium disappears, teams that historically struggled there purely on engine grounds could find themselves suddenly competitive.
