Mazda RX-4
The Mazda RX-4 (Luce/929 Rotary in some markets) brought rotary power to the mid-size family car segment. Using the same 1146cc 12A twin-rotor as the RX-2 but in a larger, more luxurious package, it produced 110 hp - slightly detuned for smoothness and reliability. Available as hardtop coupe, sedan, or station wagon (extremely rare), the RX-4 offered genuine four-door practicality with rotary smoothness. The wagon variant was particularly unusual - possibly the only rotary-powered wagon ever sold in volume. Larger and heavier than the RX-2, the RX-4 emphasized comfort over outright performance, though it still delivered respectable acceleration. Independent front suspension and a well-sorted rear axle provided good handling for a family car. The RX-4 succeeded in demonstrating that rotary engines could work in mainstream family vehicles, though fuel economy remained a weakness. Production continued through 1978 when it was replaced by the RX-5.
Wagons are extremely rare and collectible. Hardtop coupes are most desirable of common body styles. Verify rotary engine condition with compression test. Budget for inevitable rebuild. Check carefully for rust in floors, quarters, and trunk. Wagons command premium prices due to rarity. Avoid heavily modified examples. Original condition cars increasingly valuable.
