Montreal is always a brutal test for the power unit, and heading into Canada, the “SF Turbos” and the wider Ferrari engine department are under the microscope. While the team has established itself as a frontrunner, the high-speed nature of the Circuit Gilles Villeneuve is exposing the “radical” risks Maranello took with the 2026 regulations.
Here is the breakdown of the technical landscape for the SF-26 as we head to Canada:
1. The SF-26 Turbo: Low-End Gains vs. High-Speed Reliability
The core of Ferrari’s 2026 strategy was a gamble on a smaller, lighter turbocharger designed for maximum response and low-speed recovery. Under the new 50/50 power split regulations, where the MGU-H is gone, Ferrari optimized the turbo to “spool up” faster out of Montreal’s slow chicanes (like Turn 2 and the hairpin).
- The Problem: There are growing concerns about thermal efficiency and “super clipping” at the end of the long Droit du Casino straight. Mercedes currently holds a significant advantage in sustained high-end power, leaving Leclerc and Hamilton vulnerable to being overtaken at the end of the straight as the battery depletes.
- The “Spider” Correlation Issue: Lewis Hamilton recently raised an alarm regarding simulator correlation. The Maranello “spider” (simulator) pushed them toward a setup in Miami that didn’t translate to the track. For a technical track like Montreal, Hamilton is reportedly ditching simulator-heavy prep in favor of raw “track-feel” to avoid another setup dead-end.
2. The ADUO Delay: Upgrades for Canada?
Don’t expect a “magic bullet” engine in Montreal. While Ferrari is utilizing the ADUO (Additional Development and Upgrade Opportunities) framework, the significant internal combustion engine (ICE) upgrade has been delayed.
- The July Target: Reports indicate the “boosted” ICE is now slated for a summer debut likely Silverstone or Spa.
- Montreal Spec: Ferrari will likely introduce its second power unit (PU2) of the season in Canada, but it is expected to be a “reliability-first” spec rather than a performance jump. The focus is on surviving the high-torque demands of the Montreal “stop-start” layout without the turbo housing failing under high thermal load.
3. The 2026 “Mario Kart” Factor
Montreal will be the ultimate test of the new Manual Override (Boost) button and Recharge modes. Because Ferrari’s turbine is smaller, they are having to harvest more aggressively under braking.
- The Danger: If the battery “derates” (stops deploying) too early on the back straight, the speed delta compared to a car with a full charge is massive—leading to the “closing speed” accidents we saw with Bearman in Japan.
- Ferrari’s Edge: Where Ferrari does look strong for Canada is the “super-clipping” phase—the ability to top up the battery while still at full throttle near the end of the straight. This allows them to keep their Active Aero open longer than those who have to “lift and coast” to recharge.
