The TSX sits at the bottom of Acura's line-up, although the cabin tech and interior quality isn't substantially different from the more expensive TL and RL. But the TSX is a slightly smaller car from the others in the lineup and comes with a four-cylinder engine.
Although Acura considers the 2009 TSX a major update, the car doesn't look drastically different from previous versions. The grille is a bit tighter, but most of the improvements are under the hood or in the cabin tech. Even then, Acura tends to make evolutionary changes to its cars rather than wholesale redesigns.
Acura hasn't reformed the button-happy interface of its cars, with the TSX sporting 16 controls on the steering wheel alone. The lower left holds two sets of voice command buttons, one for the phone system and one for the navigation and audio systems.
We dig the gauges in the TSX, which use needles suspended from the outsides of the dials. The lack of a center pin allows room for a display on the speedometer. The tachometer face appears strangely blank.
Address entry is somewhat tedious with this interface, as you have to select each number or letter along the arc. Fortunately, it grays out letters or numbers that don't fit the selection in its database.
