Stellantis has shared more teasers and information about the upcoming Opel Sports Tourer eXperimental (STX) Concept ahead of its premiere at the Paris Motor Show on October 12. The model communicates the brand’s vision for the future of wagons, most likely previewing the next generation of the Opel Astra.

The new teasers are more revealing than the first one, giving us a good idea of what to expect. Overall, the STX Concept is not your typical wagon, as it adopts a sporty stance with futuristic details.

The front end features an evolution of the Opel Vizor grille, which is now body colored with an LED pattern and an illuminated Opel Blitz emblem. This is joined by the vertical LEDs forming the Opel Compass, and a sculpted bumper with horizontal cooling intakes.

Still, the coolest detail is the view of the profile, with the wide fenders on the rear axle making it look more like a performance model than a family-focused offering.

Opel said that aerodynamic efficiency played a crucial role in the development of the concept. One example is the design of the three-section alloy wheels, which is said to reduce consumption while offering improved “directional stability and driving pleasure at high speeds on the German Autobahn”.

In a similar context, an earlier press release confirmed that the concept features an “active aerodynamic system that continuously adapts to the driving situation, using moving elements at the rear to optimize airflow, reduce drag and improve stability.”

Sister brand Vauxhall – which also announced a redesigned Griffin logo – has shared an additional image of the STX Concept taken from above. This reveals a pair of vents that create a V shape on the hood and form front spoiler, similar in theory to the fully electric Dodge Charger Daytona. The windshield extends on the hood, with the “TECHHUE” lettering on its base hinting at a new technology.

Stellantis didn’t reveal the powertrain type of the STX Concept, but judging from their product portfolio it will be either fully electric or hybrid.

Opel doesn’t openly admit it, but the sporty wagon is expected to evolve into the next generation of the Astra, which is rumored to abandon the traditional hatchback bodystyle. The compact model has been confirmed to be renewed before 2030 alongside the smaller Corsa. Both will ride on the multi-energy STLA One architecture with an EV-first strategy. However, we wouldn’t be surprised if they eventually adopt range-extender tech from Leapmotor.

A potential rival of the future estate from Opel is the next generation of the Skoda Octavia. This one was previewed by the Vision O concept and is expected to hit the road in 2028 with a wagon bodystyle and a electric/range-extender powertrains.

Stellantis has shared the first teaser of the Opel Sports Tourer eXperimental (STX) Concept ahead of its unveiling at the Paris Motor Show on October 12. The concept is believed to preview a future production wagon, that could replace the Opel Astra before the end of the decade.

According to the automaker, the Opel STX Concept represents “its vision for the future of estate cars”. Opel has been offering family-friendly wagons since the Olympia Rekord Caravan from 1953, while the Sports Tourer moniker is used for the estate variant of the current Astra.

Florian Huettl, Opel CEO, said: “As the name indicates, the Opel STX Concept will give our vision of the future of an aero-efficient estate – a body style that Opel played a pioneering role in establishing in Europe. It shows our next generation design language and feature elements that you will see in future production models.”

The announcement is accompanied by a single teaser that doesn’t reveal much about the design. What we can see is STX concept lettering on what appears to be a portion of the front bumper, featuring a carbon-style finish against a blue or silver bodywork. The company didn’t mention anything about the concept’s powertrain type, but chances are it will feature some sort of electrification.

Stellantis has confirmed that the next generation of the Astra will arrive before 2030. The model will ride on the new STLA One architecture, offering the option between fully electric and hybrid powertrains.

Furthermore, the Opel CEO has revealed that an estate variant of the next Astra has been locked in, while hinting that the hatchback’s shape may evolve into a non-traditional bodystyle. Reading between the lines, the Astra could evolve into a sporty compact wagon and the upcoming concept might give us a good idea of what to expect.

The official debut of the Opel STX Concept is scheduled for October 12 at the Mondial de l’Automobile in Paris, although the automaker might share more teasers and additional information as we move closer to that date. The wagon will be joined by the GSE 27FE single seater for the upcoming Formula E championship, the fully electric Corsa GSE hot hatch, and the new Astra GSE Line trim.

The Opel Astra is one of the most popular compact cars in Europe, but the latest generation never got a proper hot hatch variant to rival the VW Golf GTI. While this is still the case, Stellantis has dialed up the power with a new Astra GSE Line trim, matching the power output of long-gone Astra OPC models in its most potent fully electric form.

Opel used to offer a GSe variant of the Astra with 222 hp (165 kW / 225 PS) from a plug-in hybrid powertrain, while featuring sportier looks and a sharper chassis setup. The new GSE Line is a replacement for the sporty GS trim, and will be available with every available powertrain option in the Astra lineup, including gasoline, mild-hybrid, plug-in hybrid and battery electric models.

The big news is that the flagship Opel Astra GSE Line will inherit the single electric motor from the new Corsa GSE and Mokka GSE siblings, producing 276 hp (206 kW / 280 PS). This matches the output of the turbo 2.0-liter engine in the Astra OPC J, sold between 2012 and 2018. Still, don’t expect it to be a full-blown hot hatch.

Visually, the GSE Line adopts a sportier stance than the GS it replaces and the rest of the facelifted Astra lineup. The front bumper molding is the same, but there’s extra glossy black trim around the side intakes with discreet “GSE Line” lettering.

Other changes include the trim-specific LED color in the Opel Vizor grille and 17-inch diamond-cut alloy wheels, which are optionally available in an 18-inch version. The company only showed photos of the hatchback, so we don’t know whether the GSE Line treatment will be applied to the wagon.

Inside, designers added bright yellow stitching and piping to the steering wheel, door cards, and center armrest, alongside aluminum sports pedals and an optional pair of sports seats with integrated headrests. As with the lesser Astra trims, the digital cockpit comprises dual 10-inch displays.

Opel didn’t mention any chassis tweaks, suggesting the GSE Line will likely get a standard suspension, although that may vary depending on the powertrain under the hood. Note that the Astra GSe PHEV did have a sportier setup, including a recalibrated steering, new ESP settings, and a 10 mm (0.4 inches) lowered suspension with new springs and oil-filled Koni FSD dampers.

Marc Fetzer, Opel Vice President Current Product, said that the Astra GSE Line will show how the “extra sportiness” of the GSE models can be combined with “maximum practicality for everyday use”, while giving customers a “free choice” between powertrains.

The new Opel Astra GSE Line will make its first public outing at the Paris Motor Show next month, followed by a market launch in spring 2027. Opel has confirmed that further GSE Line models will follow later in 2027, likely including the Grandland SUV.
