Firm, supportive front seats, with ventilated leather (and heating and cooling) strike a good comfort balance; all they're missing are extending thigh supports. In back, though, there's, surprisingly, just enough space for adults.
With the front seats in their rearmost position, six-footers will find headroom and legroom in back very tight—but not really any more ample than in a TL or Accord. The roofline has been awkwardly carved out to get that headroom, even. The trunk is also disappointing, as it's tiny for such a large sedan; loading isn't easy either, with the small decklid and opening.
The RL's strong suit is quietness in the cabin, thanks to a host of true luxury-car measures, including an active noise cancellation system. Meanwhile, high-quality materials, including glossy, rich wood and solid, pleasant-feeling plastics provide a relaxed, premium feeling. There's also good wind-noise isolation plus active noise cancellation to help quell any road noise—yielding an exquisitely quiet, conversation-conducive cabin.
