The 2014 Impala is powered by one of three engines, each mated to a 6-speed automatic transmission. Engine choices include a 2.4L 4-cylinder with eAssist, a 2.5L 4-cylinder making 196 hp and a 3.6L V6 making 305 hp. Chevrolet claims that the V6 is the most powerful naturally aspirated V6 in its class. At the other end of the lineup, Chevrolet expects up to 35mpg on the highway from the 182 horsepower gasoline-electric eAssist powertrain.
The Impala comes in a number of different trims including LS, 1LT, 2LT, 1LTZ and 2LTZ. LS trims are the most basic featuring cloth seats and a starting price of $27,535. Included at that price are a 6-speaker 100-watt sound system with a 4.2 inch color display, an 8-way power adjustable driver's seat, steering wheel mounted audio and cruise controls, keyless entry, automatic headlights, a noise cancellation system, 18-inch wheels and a 6-month subscription to GM's Onstar service.
1LT versions get dual zone climate control, heated mirrors, a leather wrapped steering wheel and shift knob, nicer 18-inch alloy wheels and a better stereo, which features Chevrolet's MyLink System, as well as an 8-inch screen. 2LT versions are nearly identical but also include the 3.6L V6.
1LTZ trimmed impalas feature a bevy of luxury features. As in the LT versions, 1LTZ and 2LTZ are the same, save for engine choice. Both trim levels include features such as a remote starter, keyless access and start, a heated driver and front passenger seats, ambient interior lighting, a rearview camera, 19-inch wheels, HID headlamps, chrome door handles and LED running lamps. The LTZ models also come standard with a host of extra safety features, including a lane departure warning system, cross traffic alert, blind zone alert and rear park assist.
The additional safety features of the LTZ are also available on LT trimmed Impalas. All Impalas though, feature ABS, TCS, Onstar with automatic crash response, stability control and a grand total of ten airbags.
