Performance with the 2.5-liter four-cylinder engine is fine for commuting most family use, but when power is needed for passing, the acceleration falls short of the spurt that’s available with the 3.6-liter V6, with its vivid acceleration that can almost make it feel like a sport sedan. It will do zero to sixty miles per hour in a healthy 6.8 seconds, bringing smooth, strong power.

The six-speed automatic can be shifted manually, using a switch on the lever, whose action is unfortunately awkward on account of the tall center console. Also unfortunately, the transmission isn’t seamless like some earlier GM transmissions. It shifts quickly enough, but if you’re not smooth with your foot, its response will be imperfect. So if you’re rough on the gas pedal, the transmission might be rough on you.

The Impala’s road manners are among the best in its large class, with composure and balance that’s better than the Toyota Avalon, Hyundai Azera, and Ford Taurus. It feels almost athletic out on the road, which is saying a lot for a full-size front-wheel-drive car. Quick and accurate, the belt-driven electric power steering never feels heavy or sluggish.

The Impala adeptly balances handling and a comfortable ride. Rebound springs help keep body lean under control. Excellent suspension damping keeps the ride subtle and restrained, although it feels a bit stiffer when rolling over small bumps than when encountering large ones.

Walk Around

The Impala attempts to be muscular with its chiseled lines. Its proportions are similar to the Buick Lacrosse and Cadillac XTS, but the Caddy pulls it off best, with the Buick second.

However the Impala profile is sophisticated and the lines fairly crisp. The hood is invigorating, with stamped lines and ribs. The rear is an intricate intersection of surfaces, distinct from the Lacrosse and XTS.

Interior Overview

The Impala is more spacious than the Toyota Avalon and Hyundai Azera, with ample room for five people and a their luggage if it’s not too much, in a sizeable trunk that’s 18.8 cubic feet. However the Impala doesn’t feel as big as other full-size cars.

The shape of the sweeping dual-cowl dashboard is lovely, but it’s ruined by a complex and heavy-handed mishmash of textures, lines, and materials. There are lots of storage bins in the cabin. The audio system has a hidden storage compartment behind the LCD screen. GM’s OnStar system includes a WiFi hotspot.

Support in the front seats is about the best in class, while there’s enough headroom and legroom for tall people. The power driver’s seat has an especially broad height range.

Although the back seat is wide and well shaped, the bottom cushion is low, flat, and a bit short. Yet headroom is still a bit tight, and the seat support could be better. Legroom is near limousine-level, while entry and exit is made easier by doors that are tall and wide.

As for cabin silence, the four-cylinder models include active noise cancellation, while upper trim levels are fitted with additional sound deadening and thicker glass.

Summary

The Impala offers an attractive body, composed handling and a satisfying ride. The inline four-cylinder does the job almost all of the time, as does the six-speed automatic. The V6 offers a lot more acceleration, for 3 less mpg.
