P4.8 / BODY-INTEGRATED PACKAGING
The air path belongs
inside the car.
Two enclosed passages. A clear roofline. Opening doors. The next layout asks how the airflow can fit the vehicle we want to build.
Geometric checks pass. Driving performance is not yet assigned to this body.
The 489.1 km/h peak and prepared sprint figures belong to the P4.6 reference model. This proposal changes the route, duct mass and component positions.

DECLARED ENVELOPES / COMPUTATIONAL CHECKS
Make room for every part.
The wheel envelopes cover ±100 mm travel and ±30° front steering. Door panels are checked at 0°, 15°, 30°, 45°, 60° and 75°. These are declared envelopes, not a full continuous mechanism proof, occupant-fit study or crash qualification.
QUESTION → REVISION → CHECK
Follow the reasoning.
The raised route reserved flow area but changed the car’s silhouette. The revised passages change shape around the wheel and cabin allocations, while preserving their required normal flow area.
A battery/engine overlap was removed by changing the pack’s proportions while preserving its reserved volume. A 50 mm floor-support reserve stays in the checked layout.
The duct must stay closed.
A wheel-house cut intersected about 4.25 mL of the fluid volume in an intermediate model. Local protected cuts now keep that opening out of the passage. The final geometry checks both the wheel clearance and the sealed route.
The proposed 1 mm duct skin at 1,600 kg/m³ weighs 22.72 kg. That is a preliminary skin estimate, not a complete duct, support or crash-structure mass.
P4.6 REFERENCE VEHICLE / COMPLETED CAMPAIGN
63 checks. Clear boundaries.
Sixty road, fault and plant cases pass their declared completion, lane, heading, suspension-travel and energy-balance gates. Three speed checks repeat the published peak and refine its time step and airflow interpolation. Halving the speed step changes the peak by -0.0236 km/h; the displayed 489.1 km/h is unchanged.
A passing case does not mean it stops faster than a Bugatti in every condition. The longest stop in this set is 1,236 m under an adverse scenario. The headline 441.6 m belongs to the nominal dry-road case.
These cases test the P4.6 controller and reference assumptions. They do not validate the new body, crashworthiness, sudden total floor-suction loss or underbody impact.

Geometry is one step.
Flow is the next.
Two internal-flow mesh levels are being evaluated for the new enclosed route. Their mesh, mass-balance, energy-balance and grid checks must pass before their losses can inform a driving result. No new drag or duct-loss benefit is claimed here.
Detailed manifolds, seals, hinges, human accommodation, pressure containment, materials, tyres, cooling, control failures and crash structure still require engineering and physical measurements.
