NASA HPDE Guide
NASA (National Auto Sport Association) runs one of the largest HPDE programs in the country. HPDE stands for High Performance Driver Education — it's structured driver instruction on real race circuits, organized into four run groups based on experience level. NASA HPDE is the most common entry point for drivers who want to go fast on a track legally and safely.
The Four Run Groups
| Group | Experience Level | Instructor | Passing |
|---|---|---|---|
| HPDE 1 | No track experience required | Required (in-car) | No passing |
| HPDE 2 | HPDE 1 completed | Required (in-car) | Passing zones only, with signal |
| HPDE 3 | HPDE 2 signed off | Optional (out of car) | Designated zones, by signal |
| HPDE 4 | HPDE 3 signed off | Not required | Open passing (region dependent) |
You cannot self-promote between groups — advancement requires sign-off from your instructor and approval from the event organizer. This is intentional. The structured progression is what makes HPDE safe. Don't try to skip groups.
Gear Requirements by Group
| Item | HPDE 1–2 | HPDE 3 | HPDE 4 |
|---|---|---|---|
| Helmet | SA2015+ required | SA2015+ required | SA2020 required (most regions) |
| Driving Suit | Not required | Recommended | Required (most regions) |
| HANS | Not required | Not required | Required with harness; recommended otherwise |
| Gloves | Not required | Not required | Required (most regions) |
| Fire Extinguisher | Not required | Recommended | Required, in car |
Requirements vary significantly by NASA region. The table above reflects common standards — your specific region may require suits at HPDE 3 or have different helmet certification requirements. Always read your event's supplemental regulations.
Helmet for NASA HPDE
An SA2020 or SA2015 helmet is required at all NASA HPDE events. At HPDE 4, most regions require SA2020 specifically. Buy SA2020 if you're starting now — you'll be covered for all groups. A Snell M-rated helmet is not accepted.
Car Requirements
NASA HPDE has formal tech inspection. Common requirements across all groups:
- No fluid leaks
- Brake pads with minimum thickness (typically 3mm)
- Brake fluid fresh — many events require fluid changed within a set interval
- All floor mats removed
- No loose items in cabin
- Battery secured
- Hood latches properly
NASA regions frequently require fresh brake fluid — some specify within 12 months, others require you to flush and bleed at the track. Use a high-temp fluid like Motul RBF600 or Castrol SRF. DOT 3 fluid from a stock car will boil at HPDE 3+.
Your First NASA HPDE Event
- Register online: NASA events fill up. Register weeks in advance, not the night before.
- Register as HPDE 1: even if you have track experience elsewhere, check with the event organizer before jumping groups
- Arrive early: HPDE days start early. Plan to be in the paddock 45–60 minutes before tech opens
- Tech first: car and helmet must pass tech before you can grid
- Instructor orientation: meet your assigned instructor before the first session
- Classroom: most events have a mandatory classroom/briefing session for HPDE 1-2
- Enjoy: you'll typically get 4–6 track sessions of 20–25 minutes each
