Drivers adapt to new F1 engine demands with downshifts and lift-and-coast

The first real-world test of Formula 1's 2026 cars revealed drivers must master new energy management techniques, including downshifting on straights and lift-and-coast, to harness the significantly more electrified power units. Despite the unconventional methods, drivers like George Russell and Esteban Ocon report the cars still deliver a thrilling, race-worthy challenge and feel intuitive to drive.

Why it matters:

The shift represents a fundamental change in how F1 cars are driven, moving closer to the energy-conscious style of Formula E. How drivers and teams adapt to this new engineering paradigm—balancing raw speed with strategic energy harvesting—will define the early competitive order of the 2026 season and could reshape the skill set required to succeed at the pinnacle of motorsport.

The details:

• New Power Unit Dynamics: The 2026 regulations remove the MGU-H and boost the MGU-K's output to 350kW, creating a near 50/50 split between internal combustion and electrical power. This makes battery management paramount, requiring aggressive energy harvesting.
• Driver Feedback: After testing at Barcelona, drivers confirmed the need for techniques like lifting off the throttle early before corners (lift-and-coast) and even downshifting while at full throttle on straights to regenerate the battery.
  • George Russell likened the sensation to downshifting to climb a hill in a road car, noting it felt "more bizarre in the simulator than it did in reality."
• Performance Trade-offs: Drivers highlighted the brutal acceleration out of corners but confirmed the electrical deployment doesn't last an entire straight. Ollie Bearman noted the energy management is "definitely more than what we’ve been used to," while Kimi Antonelli warned tracks like Monza will be particularly demanding.
• Engineering vs. Driver Input: Esteban Ocon clarified that while pre-session setup is crucial, much of the energy deployment during a lap is automated. He estimated the performance is "20 per cent on us, 80 on the engineers," emphasizing the driver's role is to execute the optimized strategy consistently.

What's next:

The Barcelona test provided only a first glimpse. Teams will now analyze data to refine their energy management software and driving protocols. As Russell pointed out, the current cars are just the starting point; drivability and power delivery are expected to improve significantly before the 2026 season begins, much like the evolution of the previous V6 hybrid era. The true challenge will be seen on more energy-hungry circuits, where the balance between harvesting and deploying energy will be even more critical to lap time.
