When it comes to interior space and comfort, the Acura TL's Honda Accord roots are nothing to be ashamed about. Those space-efficient origins make the TL more passenger-friendly than most other luxury sedans with its exterior dimensions--while of course the TL is more lavishly appointed through and through.
Overall, the driving position and cockpit-like feel of the instrument panel amount to an interior feel that's very different than that of the Accord. The deep, round gauges and hooded central screen--the first details you notice when you step into the deeply bolstered driver's seat--are complemented by a selection dial for screen functions that's not too low from the line of vision. We just wish Acura would have simplified the techno-cluttered instrument panel, which tends to feel a little cluttered and overwhelming until you're familiar with it, as we've noted in some other Acura models.
Generously sized, supportive front seats make the TL a joy on long highway trips--although they could use a bit more lateral support if you intent to take to the mountains. And in general, the back seat is adult-sized, with space for three across. It might appear from the outside that rear headroom might be very limited by the arch and downslope of the roofline, but with seat contouring, it works.
The only major disappointment in the 2013 Acura TL remains the trunk's meager 13.1 cubic feet of cargo space. It's less space than in many compact sedans.
The 'normal' front-wheel-drive Acura TL models are very quiet inside, and last year Acura brought more weatherstripping and additional foam insulation to these sedans. But if you get the SH-AWD, with the available 19-inch wheels, beware that a lot of road coarseness still finds its way into the cabin.
