HPD ARX-01c

Mid-engined · Naturally aspirated V8 · Downforce 3/5

A period LMP / ARX prototype: aero and platform first, mechanical grip when the wing is doing less. It rewards a settled car more than a busy pair of hands.

Get the platform calm. Aero will not forgive bounce, and neither will the tyre.

Symptoms this car reads differently

Nervous at high speed
Lifting at speed is expensive. Settle first.
Steps out on entry
Bleed into turn-in rather than dumping the pedal.
Pushes at the apex
When unsettled, fix the platform before chasing bars.
