Next Opel Astra: STLA One platform, chassis tuning and Opel-specific engineering
The next Opel Astra will use Stellantis' STLA One architecture. Opel says chassis tuning, steering, ergonomics and interfaces will preserve the brand's character.
The next Opel Astra will become significantly closer to other Stellantis cars beneath the surface. The new generation will use the STLA One architecture, which the group plans to deploy across more than 30 models. Opel says, however, that this standardisation should not be obvious from behind the wheel.
STLA One is set to consolidate five current platforms and cover B-, C- and D-segment vehicles. The architecture can be scaled for different vehicle sizes and powertrain types, while also serving as the basis for Stellantis' new electronic ecosystem. It is designed for electric vehicles and various hybrid powertrains and supports an 800-volt electrical system. Stellantis expects the new architecture to improve cost efficiency by around 20%.
One of the first important Opel models based on it will be the next-generation Astra. The car will be designed, developed and built in Rüsselsheim. STLA One supports different powertrain types, but the final engine and powertrain line-up for the next Astra has not yet been disclosed.
This is where the risk of overly similar cars wearing different badges appears. Opel CEO Florian Huettl says a shared technical foundation should not strip the brand of its own character. Chassis and steering tuning, seats, lighting, design and parts of the user experience will continue to be created by Opel specialists. In other words, components may be shared, but Opel intends to tune the car's responses and interaction with the driver independently.
An even clearer example is the new electric C-SUV that Opel is developing together with Leapmotor. International teams in Germany and China are working on the project. Opel also intends to keep familiar brand-specific solutions in the cabin: Florian Huettl has already confirmed physical buttons instead of fully touch-based controls. Production of the crossover is being considered for the Zaragoza plant in Spain from 2028.
For buyers, this will be the main test of the new strategy. If Astra, Peugeot and Citroen models increasingly share the same hardware, the differences will have to come less from the platform itself and more from steering and suspension tuning, interfaces, ergonomics and design. Opel is effectively making these details the core argument for its own identity.
