Why it matters
The Dynavia was Panhard's first concept car, an aerodynamic study on Dyna mechanicals. Its very low drag coefficient raised the top speed of the small two-cylinder car by about a fifth, and cues from its styling later appeared on Panhard production models such as the PL 17.

02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productionone car on display at the Musee National de l'Automobile (Mulhouse); the second car was lost in an accident in Switzerland | 12 | Surviving examples | Independently researched |
| Total model productionDynavia cars built ('Two cars were built') | 21 | Factory production | Independently researched |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
Panhard showed the Dynavia at the 1948 Paris Motor Show, built on the Dyna with the same two-cylinder engine. Two cars were constructed and enough parts were made for a third. One car stayed with Panhard and is on permanent display at the Musee National de l'Automobile in the former Schlumpf collection; the second was sold to Switzerland, used on the road for many miles and lost in an accident.
