Overview

Within the Citroën stable, the 1969 Citroën SM Injection and 1947 Citroën HY represent different approaches to performance and purpose. Both carry the Citroën badge, yet each carves out its own distinct identity. The 1969 Citroën SM Injection holds a clear advantage in raw power with 180 hp compared to 35 hp, a 145-horsepower difference that shapes the driving experience. Under the hood, the contrast is notable: the Citroën SM uses a V6 DOHC 24V displacing 2,670 cc, while the Citroën HY relies on a Inline-4 with 1,911 cc. Rarity plays a significant role here — with only 12,920 units built, the 1969 Citroën SM Injection is considerably scarcer than the Citroën HY's 473,289 examples.
