Compared to some of its rivals, especially the ones from Japan, the 2010 Chevrolet Impala does not match up in terms of sophistication, but it offers lots of interior and cargo space, along with a generally quiet interior.
The backseat has ample headroom and legroom, along with a flip-and-fold rear seat that allows access to a covered storage area. But TheCarConnection.com thinks that the front seats on the Impala, even though comfortable, are not suited for providing support during long hauls. Edmunds reports that “occupants will find hip and shoulder room plentiful, but legroom is mediocre for a car of this size.” Car and Driver raves that the front seats are like their "favorite recliner," but notes that "the slightest hint of aggression will rock you out of your comfort zone."
ConsumerGuide comments that the 2010 Chevrolet Impala’s "trunk is roomy, with a usefully flat floor," but "an oddly shaped opening hampers loading bulky objects"; in addition, "cabin storage is merely adequate." Cars.com reports "trunk space totals 18.6 cubic feet."
Edmunds points out that "the Impala's interior is a huge improvement over its predecessor and a nice enough place to spend time, but competitors score higher style and quality points." Car and Driver, on the other hand, is not particularly impressed with the interior materials and assembly, particularly the driver controls: "Although the redesign for 2005 greatly improved the interior, the Impala’s cabin materials still pale next to those of the Honda Accord, Toyota Avalon, and Hyundai Azera." ConsumerGuide more or less agrees, reporting that "cabin materials are serviceable, but Impala trails most like-priced rivals for quality feel ... hard plastic expanses dominate the cabin, giving it a budget look and feel."
The 2010 Chevrolet Impala provides a comfortable ride, and the FE1 suspension that's included with the 3.9-liter engine sacrifices hardly any ride comfort for the more responsive handling. Additionally, barely any road noise permeates to the cabin. ConsumerGuide reports that "wind rush and tire roar both intrude slightly."
