Interior space, along with passenger comfort in general, is a tremendous strength for the 2010 Toyota Avalon. It’s one of the roomiest of any sedans, with soft, highly adjustable front- and backseats that are contoured adequately for large adults. Edmunds considers the front seats "wide and accommodating, particularly in the Limited, which offers both ventilated seats and a seat-cushion length adjuster." ConsumerGuide states that the front of the Avalon is "large-adult roomy with supportive seats."
And with more width and legroom than most larger sedans, it can truly accommodate three adults in back. Motor Trend likens the rear seat room to "the sort of stretch space a pricey ticket buys you on Virgin Atlantic." Edmunds notes that the flat floor in the rear makes it "a legitimate proposition to seat three adults." Road & Track lauds the "flat floor and a 60/40-split rear seatback that can be reclined through 10 degrees in any of five positions."
The trunk is not only huge but deep and easy to load into—capable of holding several large suitcases. "The trunk has space enough for most family excursions, but packing gets complicated by intrusion from the wheel housings and trunklid hinges," comments ConsumerGuide. One of the few complaints is that the 2010 Avalon lacks a backseat pass-through for long objects.
Interior materials and switchgear are generally liked, though very little is said by most review sources. Road & Track likes the "flat-panel switches, which are nicely lit at night."
Overall ride comfort is pillowy, without feeling queasy, in the 2010 Toyota Avalon, which, combined with the silent, strong powertrain, creates a very refined experience: Motor Trend comments that "Toyota's flagship extends the limousine impersonation with, shall we say, noticeable silence and astute absorption of road imperfections," and ConsumerGuide says, "The V6 sounds rich during acceleration and is always subdued while cruising.”
