A large, curved digital display setup could combine the instrument cluster and central touchscreen into a seamless high-resolution interface. Faster processors and improved graphics will enhance usability and responsiveness.
Artificial intelligence is expected to play a central role in the cabin experience. The system may learn driver preferences, adjust climate settings, recommend routes, and automatically personalize vehicle configurations for different users. Premium materials will continue to define the GLS 450 interior. Buyers can expect high-quality leather upholstery, open-pore wood trim, brushed aluminum accents, and optional sustainable luxury materials. Mercedes-Benz is increasingly focusing on eco-friendly interior production without sacrificing premium quality.
The front seats are expected to offer improved ergonomics with multi-stage heating, ventilation, and massage functions. Long-distance comfort will remain a key priority for GLS customers. Second-row seating is also expected to improve significantly. Executive-style captain’s chairs may be offered on higher trims, providing enhanced comfort, leg support, and optional entertainment systems. Even the third row is expected to benefit from design improvements, including better cushioning, easier access, and improved climate control, making the GLS one of the most practical luxury three-row SUVs.
Ambient lighting is expected to become more advanced, offering customizable themes with dynamic color transitions that can respond to driving modes or music. Noise-insulation improvements, such as acoustic glass, enhanced sealing, and active noise-cancellation systems, are expected to create a quieter, more relaxing cabin environment.
