Package and aerodynamics
These are the dimensions and aerodynamic coefficients the programme's own physics model runs on, taken from Source/MotorWorks/Data/VehicleConfigs.h. They describe what each body was modelled to. They are not measurements of a finished car, because no car here is finished.
Ten of the eighteen vehicles have a physics configuration. The other eight are not listed, rather than estimated.

Reading the aerodynamics
Cd is the drag coefficient — how hard the body pushes against the air. Lower is more efficient. Cl·A is lift coefficient area, derived from the downforce the configuration records at 150 mph. Positive numbers press the car down.
Ironside's Cl·A is −0.05. That is net lift, and it is the correct answer for a 1,920 mm-tall square-shouldered body — a truck of that shape does not make downforce. It is recorded rather than rounded up to zero.
The spread is the interesting part. Cyclotis runs a Cl·A of 2.00 at a Cd of 0.29, which is a body doing real aerodynamic work. Velma sits at 0.10 and 0.37 — packaged for interior volume, and honest about it.
427 Turbo · Cl·A 1.67
High downforce; the body is working aerodynamically at speed.
Vindicator · Cl·A 1.78
High downforce; the body is working aerodynamically at speed.
Ember RS · Cl·A 0.16
Trivial downforce; the body is packaged for space, not for load.
Foundry 427 · Cl·A 0.51
Moderate downforce, balanced against drag for road use.
Soray · Cl·A 0.33
Moderate downforce, balanced against drag for road use.
GT-1 · Cl·A 0.40
Moderate downforce, balanced against drag for road use.
Cyclotis · Cl·A 2.00
High downforce; the body is working aerodynamically at speed.
Velma · Cl·A 0.10
Trivial downforce; the body is packaged for space, not for load.
Summit · Cl·A 0.21
Trivial downforce; the body is packaged for space, not for load.
Ironside · Cl·A -0.05
Net lift at speed — expected for a tall, square-bodied vehicle.
What is not here
Sirena Seraphine, Meridian, Noctis, BluJay, Robyn, 327 S, SR-7 and D87 have no entry in the physics configuration, so they have no row. Their body work exists; their package numbers are not settled, and a plausible estimate on a specifications page is indistinguishable from a fabricated one.
Power, torque and acceleration are not on this page either. Those are reported per vehicle, and only where a real specification sheet exists.
Source: Source/MotorWorks/Data/VehicleConfigs.h via NORDSCHLEIFE_DOSSIER/FLEET_SPEC_MASTER.md, generated 2026-07-04. Cl·A is derived as 2·DF / (ρ·v²) at v = 67.06 m/s. Simulation parameters, not homologated measurements. Every vehicle on this site is concept-stage; none are in production, and nothing here is for sale.
