When the next new Impala appears in the 2014 model year, it'll update its infotainment feature set with the latest in connectivity and entertainment.
The 2013 Impala, the last year of a long-running model, doesn't have many of those features, putting it at a disadvantage to cars like the current Ford Taurus and Hyundai Azera.
The base Impala does have a fair amount of standard features, especially for its price. Standard features on the basic Impala LS include power windows and mirrors; cruise control; an AM/FM/CD player with satellite radio; steering-wheel controls; Bluetooth and keyless entry. This version's primarily intended for fleet use, so it omits some key features--things like power side mirrors and a folding rear bench seat.
Stepping up to the LT, you earn flip-and-fold rear seats, remote start, dual-zone automatic climate control, 17-inch machined aluminum wheels, and a somewhat firmer Touring suspension. The LTZ is the top-of-the-line, sporty Impala, and adds a Bose sound system, W-rated tires on 18-inch wheels, fog lamps, heated mirrors, power front seats, leather upholstery, and a garage-door opener.
Otherwise, the Impala is missing a lot. USB port? Not here. Navigation? No. A sunroof? No. But the Impala does have OnStar hardware and comes with a six-month subscription to basic services (you'll have to pay a monthly fee after that).
