Vauxhall STX Gives a Preview of the New Generation Astra Estate

The Vauxhall STX concept, the electric estate study whose world premiere Opel/Vauxhall staged at the Paris Motor Show and which offers the first clear glimpse of the design direction of the next-generation Astra Sports Tourer. Its name stands for "Sports Tourer eXperimental"; the vehicle was unveiled at the Opel press conference on October 12, 2026, and showcases the next evolution of the brand's "Bold & Pure" design language. In this article, we examine the STX's dimensions, the official signals regarding its electric powertrain, and how it will be reflected in the new-generation Astra estate.

What Does the STX Concept Tell Us?

The STX is tangible proof of how the designers in Rüsselsheim envision the future of the estate body style. The "Sports Tourer eXperimental" phrase in its name already sums up the intent: a study attempting to carry Opel's estate tradition into the electric era. The brand describes the concept as a vision of the electric station wagon body style and the third phase of the Bold & Pure design language.

The overall atmosphere of the stand in Paris also supports this intent. Stellantis had announced that it would attend the show with more than 60 vehicles, nine of which are concepts; accompanying the STX in Opel's area were the final appearance of the GS 27FE, which raced in the brand's first Formula E season, and the high-performance world led by the new Corsa GSE hot hatch. So the STX is not a standalone design exercise; it is a central piece of Opel's vision of the future.

Dimensions and Technical Data: What Is Official, and What Is Not?

The concept's dimensions are remarkably long for an estate: 5,040 mm length, 1,996 mm width and 1,760 mm height. The official information Opel has shared about the powertrain is limited: a fully electric setup, permanent all-wheel drive, and a top speed above 200 km/h. Details such as range, battery capacity or horsepower were not disclosed.

Let's add a word of caution here: figures circulating on social media, such as 2.6 seconds 0-60 mph, 400-mile range and 480 hp, are not data confirmed by Opel. Having watched this business for more than thirty years, let me note that the proliferation of such figures at concept reveals, like airport newspaper stories, is nothing new; it is best not to give them credence until official information comes out.

Wheels and active aerodynamics

Underneath the body are 22-inch three-piece aerodynamic wheels and Goodyear tires in 285/35 R22 size. More interesting are the blue-colored diffusers that open according to speed, the vertical bumper elements behind the wheels, and the movable aerodynamic elements at the rear. In the concept world, aerodynamics is no longer an aesthetic detail but the very core of range strategy - and STX defends this visually as well.

How Will the Design Language Reflect on the Next-Generation Astra?

The STX's front features an evolved Opel Vizor face that is taller and more pronounced than previous concepts; a new lighting signature and an illuminated Opel Blitz logo accompany it. The characteristic curve on the hood is executed as a separate design element called Opel Compass; at the rear, thin illuminated compass axes and an illuminated OPEL lettering in the center are visible. The horizontal LED taillights carry the lamella look from the front face to the rear. Glass light strips in the C-pillars, illuminated STX lettering on the sides, and cameras replacing the exterior mirrors are also on the list.

There is a separate touch for the Vauxhall version: at the front, the Griffin emblem, illuminated for the first time in the brand's history, and adaptive headlights stand out. Inside, there is immersive lighting and lightweight seats continuing the "Painting with Light" approach we first encountered in the 2023 Opel Experimental and the 2025 Corsa GSE Vision Gran Turismo.

How much of it will remain in series production?

The designers present the car as an estate with a low roofline extending to an almost vertical rear tailgate - there is no raised crossover-like stance. In the designers' words, the length is slightly more than the field. However, some details such as camera mirrors and active aero in the front bumper are unlikely to make it into the production Astra; these are the familiar ornaments of the concept world. What will truly endure are the Vizor front face, the lighting signatures, and the overall proportions.

When Is the New Astra Estate Coming?

The STX is read as a direct harbinger of the ninth-generation Astra Sports Tourer, and the industry's experienced publications state this openly. The date indicated for the future model is 2029. According to the assessment by Automotive News, the concept is a preview of the compact wagon that could replace the current Astra Sports Tourer and will be based on one of Stellantis' STLA platforms. According to the plan confirmed by Opel executive Florian Huettl, the next-generation Astra is one of at least four new Vauxhall models expected to launch by 2030.

Another signal regarding the likelihood of series production comes from the manufacturing side: it is said that the future model could benefit from Stellantis' efficient European production network, including Zaragoza. This is one of the most concrete signs that the concept is not merely a showcase vehicle. Opel's estate tradition, ongoing since the 1953 Olympia Rekord Caravan, continues in the electric era as well.

Connection to the Current Astra Lineup and Stellantis Strategy

When evaluating the STX, it's also worth remembering the current Astra on sale. The facelifted Astra, which made its debut at the January 2026 Brussels Motor Show, was in the spotlight with its new look, its Electric version with a 454 km WLTP range, and its new 17/18-inch wheels; the same pricing strategy is being applied to the electric, hybrid, and plug-in versions. In addition, the new GSE-Line trim level shown for the current lineup points to a version with 280 hp. So the STX doesn't exist in a vacuum - it stands on a live and evolving lineup.

Within Stellantis, the position of Opel/Vauxhall in the compact segment is also becoming clearer: In CarBuzz's assessment, the concept is seen as proof of Opel's determination to keep the compact wagon segment alive, and it is suggested that the brand's electric platform could in some way make its way to the US. As old software engineer friends would say, the estate body style stirred the pot in Europe for many years; although the crossover wave has shrunk this market, Opel remains one of the few manufacturers still defending this form.

Conclusion: Was the Future of the Estate Decided in Paris?

The STX alone won't sell a single estate; that job will fall to the new Astra Sports Tourer, pointed to for 2029. The real value of the concept is that it lets us see, starting today, the next phase of the design language and the proportions of the electric estate architecture. Sweep away the gimmicks like active aerodynamics and camera-based mirrors; the Vizor face, lighting signatures, and that long, low silhouette will most likely appear on the production car. I say this out of thirty years of habit: the future isn't bought at concept shows, it's only observed - and the STX is worth observing.
