02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productionRoadpacers sold | 7991 | 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
Holden Premiers were shipped to Japan without engines and fitted with a 1.3-litre 13B Wankel rated at 130 horsepower. The AP stands for anti-pollution. The car competed with the Nissan President, Isuzu Statesman de Ville, Toyota Century and Mitsubishi Debonair, but the rotary engine was underpowered for such a heavy car compared with their V8s.
