Opel has revealed the name and first official image of its next concept car. The Opel Sports Tourer eXperimental Concept, shortened to Opel STX Concept, will make its world premiere at the 2026 Paris Motor Show on 12 October. Opel describes the study as a vision for the electric estate cars of tomorrow, not as a confirmed production vehicle.

What STX stands for

The initials come from “Sports Tourer eXperimental”. They connect the concept with Opel’s Sports Tourer estate cars, including the Astra Sports Tourer, while the final letter underlines its experimental status. Opel has not announced a production date, a price or a technical specification for a car derived from the STX Concept.

The official image shows a long, low body with a strongly sloping rear section. The side surfaces are clean and tightly drawn, while the proportions remain recognisable as those of an estate rather than a conventional SUV. The photograph offers design information, but it cannot establish the concept’s dimensions, battery capacity, range or motor output.

World premiere in Paris

The STX Concept will be shown at the Mondial de l’Auto 2026 from 12 to 18 October. Opel has scheduled its press conference for 11:40 CEST on Monday, 12 October, at stand A42 in Hall 4. This confirms when the study will be presented, but it does not mean that customers will be able to order a production model with the same body.

Opel will display several other projects at the same stand. They include the Opel GSE 27FE, the brand’s GEN4 Formula E racing car for the 2026/27 season, and the Corsa GSE. The Astra will also appear with a new GSE Line trim. Opel says that trim will be available to order from spring 2027 and can be combined with battery-electric, plug-in hybrid, hybrid and conventional powertrains.

An electric estate rather than an SUV

Opel’s own description places the STX in the estate category, even though its design uses details that can also be found on crossover vehicles. The reference to Sports Tourer points to a longer roofline and a body designed around passenger and luggage space. It is not an announcement of a new SUV and it is not presented as a direct replacement for a current model.

Opel has not released the study’s length, width, height, wheelbase or boot capacity. The company has also not specified the number of seats, the battery size or the electric motor configuration. The STX should therefore be treated as a design and technology study rather than a product sheet for a future showroom car.

Design and active aerodynamics

The press material describes the STX as another step in Opel’s design language. The concept uses a more prominent version of the Opel Vizor, with light animations integrated into curved slats. Its rear window and roofline slope sharply, and the body panels have flush, technical surfaces.

Opel also confirms an active aerodynamic system. Moving elements at the rear are designed to adjust continuously to the driving situation, helping to optimise airflow, reduce drag and improve stability. The manufacturer has not published a drag coefficient or a measured consumption benefit, so the effect cannot yet be assessed with a number.

Aerodynamics are particularly relevant to an electric estate because air resistance has a greater influence on consumption at higher road speeds. However, a concept can contain systems that never reach production in the same form. Opel says the STX includes elements that anticipate future models, but it has not identified which components will be carried over.

The connection with the Astra Sports Tourer

Opel refers to the Astra Sports Tourer as the current continuation of its estate tradition. The STX Concept is not described as the Astra’s direct successor and Opel has not announced an STX-based replacement. The connection is instead about design and body style: both use the Sports Tourer idea for a practical car with a longer rear section than a hatchback.

The Astra GSE Line will be shown alongside the concept. It is a production-car trim level rather than a separate concept and will be available with several types of powertrain. Keeping the two announcements separate matters: the GSE Line has a planned ordering window, while the STX remains an experimental study.

Opel’s electric models in Paris

The Paris display will also show the breadth of Opel’s current electric range. The Corsa GSE is a production hot hatch with 207 kW and 345 Nm. Opel quotes a 0–100 km/h time of 5.5 seconds. The Mokka GSE uses the same peak output and brings design and technology inspired by the Mokka GSE Rally to a road car. These figures apply to the production GSE models, not to the STX Concept.

Opel will also display the Grandland Electric AWD, rated at 239 kW and 509 Nm, and the Frontera Electric Extended Range. For the Frontera, Opel quotes a 54 kWh battery, of which 52 kWh is usable, and a WLTP range of up to 400 kilometres. Those are official figures for a production model and should not be transferred to the concept.

For now, the STX says more about Opel’s design direction than about a confirmed future model. The Paris premiere may reveal the interior, propulsion layout and further aerodynamic functions. Any production date, price, battery or range figure would still need a separate announcement from Opel.
