Citroen SM

Introduction

The Citroën SM, produced between 1970 and 1975, was a groundbreaking grand tourer that combined French innovation with Italian performance. It showcased Citroën’s futuristic design and advanced technology while using a Maserati V6 engine, reflecting the company’s ownership of Maserati at the time. Positioned as a luxury GT, the SM offered exceptional comfort, high-speed cruising ability, and a distinctly avant-garde character that made it one of the most iconic cars of its era.

Exterior

The SM’s exterior was striking and aerodynamic, with a long, low silhouette and smooth, flowing lines. Its covered glass headlamp cluster, tapered nose, and sculpted body panels created a futuristic appearance that was far ahead of its time. The sloping rear and chrome details enhanced its elegance, while the wide stance and alloy wheels emphasized its sporting intentions. It was both elegant and radical, instantly recognizable on the road.

Interior

Inside, the SM featured a luxurious and innovative cabin designed for comfort during long journeys. Distinctive oval dials, a single-spoke steering wheel, and plush seating highlighted Citroën’s unique approach to ergonomics. High-quality materials such as leather and chrome gave the interior a premium feel, while advanced features like adjustable suspension height controls reinforced its futuristic character. It was designed to blend driver engagement with passenger comfort.

Safety features

For its time, the SM incorporated advanced safety elements including disc brakes on all four wheels, power-assisted steering, and Citroën’s hydropneumatic suspension for enhanced stability and control. The strong chassis and responsive handling improved confidence, while the enclosed headlamps with self-leveling technology provided excellent nighttime visibility.

Engine trims

The Citroën SM was powered by Maserati-derived V6 engines ranging from 2.7 to 3.0 liters, delivering between 170 and 180 horsepower. Paired with manual and automatic transmission options, these engines allowed smooth high-speed cruising typical of a grand tourer. Its combination of Italian power and French engineering made it one of the most refined GTs of the 1970s.

Maintenance

Maintaining the SM was complex, particularly due to its advanced hydropneumatic suspension, unique steering system, and Maserati engine. Specialized knowledge and parts were required, making upkeep costly compared to mainstream cars. However, for enthusiasts and collectors, the SM remains a prized classic worth the effort, appreciated for its engineering brilliance.

Competitors

The Citroën SM competed with luxury GTs like the Jaguar E-Type, Maserati Indy, and Mercedes-Benz SL. Unlike its rivals, it prioritized comfort and futuristic design alongside performance, creating a distinct niche. Its combination of style, speed, and technology ensured its place as a timeless automotive icon.
