The Citroën GS Basalte: a gem born from a missed encounter with America
As we have previously explored in our series dedicated to the saga of Citroën special editions, the brand with the double chevrons has always been a pioneer in limited editions within the European market. By the mid-1970s, the manufacturer understood that personalization and exclusivity could breathe new life into established models while appealing to customers seeking distinction. Following the success of the 2CV Spot in 1976 and the Dyane Caban in 1977, Citroën decided to apply this formula to its mid-range sedan. Today, we focus our attention on a particularly singular version that has much to teach us about the boldness and marketing opportunism of the era: the Citroën GS Basalte.
A limited series with lightning success in April 1978
It was specifically on April 5, 1978, that the Citroën GS Basalte made its debut across the dealership network. Produced in only 5,000 units for the entire European market, of which 1,800 units were strictly reserved for France, it was launched at a price of 29,700 Francs. To put this figure into perspective, this amount would represent approximately 18,803 euros today, accounting for inflation and the evolution of purchasing power. Although sold for 3,300 Francs more than the Club version upon which it was based, the enthusiasm was immediate. Just fifteen days later, by April 20, the entire stock was already sold out, demonstrating an unprecedented commercial success for a car in this category.
Visually, the GS Basalte broke radically with the usual sobriety of the GS range. Its bodywork was draped in a deep black, simply named "Basalt Black," enhanced by wide red side stripes with a very dynamic design, evoking magmatic flows. It proudly displayed a specific logo on its hood and featured equipment normally reserved for the high-end Pallas trim, such as stainless steel wheel covers. The interior was equally impressive, featuring upholstery in a red and black "houndstooth" pattern, an unusually thick black loop carpet, and a wealth of comfort features for the time, including a sunroof, tinted windows, and a cassette radio with orange buttons matching the interior ambiance.
The only special series based on the GS: a mechanical rarity
Under the hood, the GS Basalte remained faithful to the proven mechanics of the GS 1220 Club. It featured the famous 1,220 cc air-cooled four-cylinder flat engine (boxer), developing 65 horsepower. This block was mated to a four-speed manual gearbox, offering the flexibility and characteristic sound that made the GS's reputation. It is important to emphasize that the Basalte holds a unique place in the model's history: it is the one and only special series created on the base of the original GS. All subsequent limited editions, such as the Chic or Tuner versions, would be developed on the base of the GSA, the evolved version with a hatchback that appeared later.
This particularity makes it an extremely sought-after model for enthusiasts and collectors worldwide today. Its rarity is such that it has become exceptional to come across an example in good condition, most having succumbed to the ravages of corrosion or heavy use during the 1980s. But beyond its technical specifications, this unique series on the GS hides a far more surprising genesis than it seems, linked to thwarted international ambitions.
The incredible genesis: recycling the failure of the "Export USA" Project
The story of the GS Basalte is intimately linked to Citroën's disappointed ambitions across the Atlantic. In 1972, the prestigious Citroën SM had been elected car of the year in the United States, a first for a foreign vehicle. Buoyed by this aura, the manufacturer seriously considered exporting its mass-market models, the CX and the GS, to American soil. In 1977, a specific "Export USA" version of the GS was developed to meet the drastic safety and equipment standards of the United States. This project included accessories entirely new to Europe, notably front headlight wipers and specific lighting devices.
However, the project was abruptly halted, officially due to complex homologation reasons, but unofficially due to Peugeot's takeover of Citroën, which preferred to limit risky investments in the North American market. Citroën then found itself with a considerable stock of parts and accessories intended for the American market. Rather than scrapping these components, the marketing department had the genius idea to create a "flashy" limited series to sell off these stocks. Thus, the famous headlight wipers, originally intended for Californian highways, were included as standard on the Basalte. This strategic recycling transformed an industrial failure into a true commercial masterstroke, making the Basalte a hybrid car between French elegance and American technical requirements.
A legacy that endures in the contemporary range
In conclusion, the Citroën GS Basalte remains undoubtedly one of the most striking and authentic special series in the brand's history. While it may not enjoy the same popular fame as the Charleston or Cocorico versions of the 2CV, it offers a historical richness and technical exclusivity that place it at the top of the hierarchy of collectible Citroëns. It embodies that typically Citroën ability to transform an industrial constraint into an object of desire.
Today, the influence of the GS is more vibrant than ever within the current range. Citroën has explicitly claimed the aesthetic and philosophical connection between the GS and the modern C4, seeking to recapture that unique compromise between aerodynamics and hydraulic comfort. Even more striking, the recent launch of the Citroën Basalt model directly revives the name of this legendary 1978 special series. This choice of name shows how much the legacy of the GS Basalte continues to infuse the brand's DNA, proving that forty-eight years later, the spirit of this "volcanic" sedan continues to inspire the engineers and designers of the double chevrons.
