The interior of the 2011 Acura RL, while one of the quietest and very comfortable for those in the front seat, is far from the roomiest and really only fit for four adults. The RL's front seats are firm and supportive, with ventilated leather (and heating and cooling) striking a good balance, even though they're missing extended thigh supports. In back there's enough room for adults, even with long-legged front seat riders. The roof has been carved out to provide more head room for tall passengers.
The trunk also feels minuscule for a vehicle in this segment, too; the decklid and opening are quite small, and toward the frontal portion the space tapers inward and upward.
The Acura RL's real strong suit is quietness in the cabin, thanks to thicker glass and more insulation than rivals, while high-quality materials, including glossy, rich wood and solid, pleasant-feeling plastics, provide a relaxed, premium feeling. An active noise cancellation system and excellent sealing from wind noise means that even on the highway, at super-legal speeds, you'll be able to carry on a quiet, relaxed conversation.
