Eleven km/h top speed gain on the straight: measuring slipstream in the Zandvoort Sprint

Analysis across 324 laps of the Zandvoort Sprint quantifies the straightline slipstream gain: 11.08 km/h higher top speed when following within one second.

Top speed delta Aerodynamic tow down the main straight

Across 24 laps of the Dutch Sprint, analysis of 324 laps across eleven drivers isolated the slipstream impact along the pit straight. Following within 1.0 s of the leading car yields an average top speed increase of 11.08 km/h compared to clean air laps (gaps over 2.0 s).

The tow effect cuts aerodynamic drag on the climb into Tarzan braking, creating overtaking opportunities even for high-downforce setups.

Twisty sector penalty The downforce cost of dirty air in fast sweeps

Straightline speed contrasts with cornering load loss in the technical sections. Through Zandvoort's fast sweeps, wake turbulence reduces underfloor suction by over 15%, forcing wider lines and causing tyre scrub.

Strategic takeaway Potent for attacking, taxing on tyre compound

Telemetry confirms slipstream at Zandvoort provides sharp attacking advantage, but running in close wake beyond four consecutive laps risks critical thermal tyre degradation.
