2024 Mercedes-Benz GLS vs 2023 Lexus RX

The 2023 Lexus RX presented a refined exterior with a shorter height, broader width, and longer wheelbase, maintaining the same overall length as its predecessor. Despite offering more cargo space than the 2022 model, it appeared smaller due to reduced rear overhang and softer design lines. The floating roof effect, created by the down-sloping black trim on the rear pillar, contributed to a stubby appearance. The front featured a spindle-style grille integrated into the design, with a modern mesh texture flowing into an elevated hood. The RX's styling was familiar yet fresh, distinguishing it from the previous generation and the smaller NX model.

Inside, the RX boasted a modern interior with fewer buttons, digital instrumentation, and a choice of touchscreen displays. The Intelligent Assistant technology offered ease of use, though it required a subscription after three years. High-quality materials were evident, with options for NuLuxe artificial leather, genuine leather, and simulated suede. The RX 350 was available in various trims, including Standard, Premium, and F Sport Handling, with pricing expected to remain close to the previous model's base price of just over $47,000.

The Intelligent Assistant offered natural voice recognition, though it occasionally provided inaccurate results. The system allowed user profiles and music streaming but lacked the ability to view multiple data panels simultaneously.
