Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 GLS450.
As the 2023 iteration of the GLS450, this entry represents one model year in a nameplate that sits at the upper end of the manufacturer's SUV range and serves as the gateway trim within the GLS family for that production year. The supplied reference material does not include verified engine output, equipment content, or efficiency figures for this vehicle, so any standout specifications should be drawn directly from primary sources such as the manufacturer's published data or EPA filings rather than inferred from the trim designation alone. For researchers building a longitudinal record, the 2023 GLS450 should be treated as a single data point whose place in the nameplate's reliability history can only be established by cross-referencing verified consumer-reported dependability, warranty-claim records, and recall documentation—anchoring any conclusion about this model year in evidence rather than assumption.
