How do the 2026 cars change strategy at Spa?

Answer

The 2026 cars drop DRS for active aero and an electric Overtake boost, and run a power unit that is roughly half electric. At Spa, with the long Kemmel straight and the flat-out run through Eau Rouge, that turns the lap into an energy-management problem: teams must charge a much bigger battery for the straight and the Overtake zones while still setting the car up for the fast second sector.

What changed on the car

For 2026 the cars carry active aerodynamics with two settings: a Straight Mode that opens the front and rear wing flaps to cut drag on the straights, and a Corner Mode that keeps the high-downforce position for the turns^[1]. DRS is gone, because with everyone shedding drag on the straights an opening rear wing no longer offers an advantage^[2].

The overtaking aid is now a manual boost, branded Overtake, usable when a driver is within one second of the car ahead, and it comes from extra electric power rather than a wing flap^[2]^[3]. The power unit is close to a 50-50 split between the engine and the electric side, with deployable electric power rising from 120 kW to 350 kW^[4].

Why that matters most at Spa

Spa is defined by the run from La Source through Eau Rouge and down the Kemmel straight, a long flat-out stretch that on the old cars was the prime DRS-plus-tow overtaking zone. In 2026 that move becomes a tow-plus-electric-boost move. The driver who has saved battery for the run to Les Combes, and who times the Overtake button well, gets the pass. The driver who drained the battery too early arrives with nothing left.

That makes energy management a lap-long strategy question. With a 350 kW deployment to charge and spend, engineers plan where to harvest and where to unload, and drivers lift and coast in places they never used to. Spa has long full-throttle sections and relatively few heavy braking zones to recover energy, so the battery has to be nursed carefully to be ready for the straight and the passing zones.

At the same time the fast second sector still demands downforce, so teams cannot simply trim the car out for Kemmel. The old Spa wing compromise now sits on top of a battery-management problem, and in 2026 the whole grid is learning that balance for the first time.

The knock-on for tyres and stops

The long, fast corners that define Spa still load the tyres hard, so tyre life remains a limiting factor alongside energy^[5]. How the new aero balance and the differently powered cars work the tyres over a stint is something teams can only learn once running begins.
