With a rather conventional MacPherson strut-type front suspension and trailing-arm rear suspension, with a stabilizer bar in back, the Impala is tuned to bring a smooth ride yet handle reasonably responsively. The body and suspension systems were designed to include some significant sound-deadening measures, which make the Impala quiet on the highway and over coarse surfaces.
Depending on the trim level, the Impala comes with either a front bench seat or two individual buckets. In back, there's enough room for three adults across, and the seatbacks on some models fold forward for a full pass-through to the trunk for larger cargo items. There's a storage tub under the rear cushions and a sunroof is available.
Side and side-curtain airbags are standard on all Impalas, along with GM's StabiliTrak stability control system and 4-wheel anti-lock disc brakes. There are LATCH child-seat connectors in all three rear seating positions.
Even the base LS model includes keyless entry, cruise control, power windows and locks and air conditioning. LT models get larger machined aluminum wheels, a remote start system, dual-zone climate control and Bluetooth hands-free connectivity. At the top of the range, the LTZ comes equipped as a more sophisticated, somewhat sporty sedan, with upgraded wheels and W-rated tires, heated seats, heated mirrors, a universal remote, and Bose audio. All sound systems include an auxiliary input. Also included in the Impala is the latest Gen 9.0 version of OnStar, with improved voice recognition, along with Direction and Connections services and Turn-by-Turn navigation, which allows you to beam route guidance from a call center into the vehicle.
The available Luxury Edition Package for LT models boasts heated front leather seating, passenger side power adjustability, an 8-speaker Bose audio system, heated power mirrors, Universal Home Remote, and a yearlong subscription to SiriusXM satellite radio.
