Opel STX Concept: This is what the electric family car will look like, paving the way for the brand’s future
Opel aims to regain its leading position it held for years in the family car market, and will use the Paris Motor Show, taking place from October 12 to 18, to present a concept that goes beyond mere design and gives insight into the direction of its upcoming models.
The brand will accompany this innovation with a strong display of its sports versions. Visitors can see the new Opel Corsa GSE and Mokka GSE, as well as the GSE Line trim for the Astra in both sedan and family versions. The GSE 27FE single-seater car, which Opel will use to compete in the 2026-2027 Formula E season driven by French driver Théo Pourchaire and New Zealander Mitch Evans, will also be on display.
Opel STX Concept: a sports family car that previews the brand’s future
The main focus is the Opel STX Concept, short for Sports Tourer eXperimental, a prototype through which the company envisions the future of family cars amid the dominance of SUVs. This isn’t new territory for Opel: since the 1953 Olympia Rekord Caravan, the brand has maintained a consistent presence in this category, with well-known models such as the Kadett and the current Astra Sports Tourer.
Opel claims this prototype is not just a design exercise but a statement of intent regarding what its future family models will look like. Some of its aesthetic and technological solutions will make their way to upcoming production models, though the manufacturer has not yet specified which ones or when.
The STX Concept features a low, wide, and sporty body style with sharp lines and a silhouette reminiscent of high-performance models. The rear section has a moderately sloping roof that ends in a raised, robust, and almost vertical trunk lid—a design choice aimed at balancing a bold appearance with the functionality typical of this vehicle class.
Opel has not yet released the official dimensions of the prototype. For reference, the current Astra Sports Tourer is 4.64 meters long, so the STX Concept is likely to be in a similar size range, though we will have to wait to know its exact measurements. What is confirmed is that it is a 100% electric model with all-wheel drive.
The 22-inch alloy wheels, divided into three pieces and designed to improve air flow, enhance its sporty image. They are paired with Goodyear tires sized 285/35 R22 and are mounted on widened wheel arches that emphasize the vehicle’s overall width.
A design aimed at improving aerodynamics
The front end is one of the most striking features of the Opel STX Concept. The brand has reinterpreted its iconic Vizor—a surface that combines the grille and lighting elements—to give it more prominence and extend it across almost the entire front portion. At the center sits a large illuminated logo, accompanied by thin vertical lines of light.
The rear also follows a similar philosophy, with small illuminated lines that resemble a compass and frame the Opel name, which is likewise backlit. Thus, the lighting serves not only a practical function but also contributes to the visual identity the company aims to convey in its upcoming vehicles.
However, the design is not driven solely by aesthetic considerations. Opel has paid special attention to aerodynamics, featuring a sculpted hood, small air inlets at the ends of the front bumper, and exterior mirrors replaced by extremely compact cameras. The wheel arches and side skirts also have specific shapes to manage airflow around the bodywork.
Opel has not provided figures for power, battery capacity, or range, but it has confirmed that the STX Concept can reach a top speed of over 200 km/h. For now, there is no information available to determine its full performance or predict what technology might be used in a potential production version.
The cabin also holds some mysteries. The brand has yet to release official images of the interior, though it has indicated that the prototype will build upon the Painting with Light concept—a design that combines illuminated elements integrated into the occupants’ surroundings with seats made of lightweight materials.
This philosophy was already demonstrated in the 2023 Opel Experimental and the 2025 Corsa GSE Vision Gran Turismo. The STX Concept will be used to explore further developments of these solutions, though we’ll have to wait until its unveiling in Paris to see how they are implemented in the interior.
