奇怪，从倒数第四张图中看，后部空间似乎还不够宽敞。相比之下，同一级别的LEXUS LS460L已经把飞机上的公务舱座椅移植过来了：“The LS460L's extra length allowed Lexus to create an optional ottoman package wherein the right-side rear seat reclines 45 degrees and has power leg rests and a massage feature.”
其中最主要的原因是LS460L在设计时就充分考虑了后排乘客的舒适性，“The long-wheelbase LS460L measures 202.8 inches in length versus the LS460's 198.0 inches, with a 121.7-inch wheelbase versus the stock 116.9-inch wheelbase. Lexus claims that the long-wheelbase model will establish new levels of comfort and luxury in the premium-sedan class.”
