Seating room is in ample supply in the Lexus LS, and even more regal in the long-wheelbase versions. The cabin isn't extravagant with over the top materials, but it's dazzling in its obvious attention to finish and fit and detail.
The LS's front seats aren't all that supportive--Sport models have a bit more bolstering--they're wide, multi-adjustable, and softly cushioned for interstate treks. The LS seems narrower inside than the big German luxury sedans, and the center console's fairly wide. Regardless, knee and head room are still good.
The back seat is where the LS does its convincing impression of a German executive sedan, especially in long-wheelbase form. In either, tall passengers will have no issues with space or comfort, and the five extra inches of wheelbase in the L models gives them limousine-like leg room. The space alone doesn't impress you? Lexus offers upgraded seats with massaging functions and ottoman-style footrests, as well as power adjustment for the backrest.Trunk space and interior storage are fairly large, and hybrids have 2 cubic feet more space thanks to a recent repackaging of their batteries. As for quality, few vehicles at any price point are assembled with the Lexus LS' tight panel gaps, though other luxury four-doors offer far richer-looking materials. Some of the LS switchgear mimics that used in much cheaper Lexus models, but the same can be true of vehicles from Mercedes, BMW, Jaguar, and Audi, too.
On top of it all, trims remain impressive even when matched up with those in top Mercedes and BMW flagships, and the top-notch aniline leather is supple and delicate compared to what you get in other Lexus models. The cabin of the LS models, no matter which one you get, is tight and hushed from wind and road noise more than nearly any other model. You only slightly hear the engine when accelerating.
