The 2011 Chevrolet Impala, part of the ninth generation, is a RWD full-size sedan available in 3 trims: LS, LT, and LTZ. All models are powered by a 3.5-liter V6 engine that produces 211hp, paired with a four-speed automatic transmission. On its high-end LTZ variant, a 3.9 liter V6 engine with 230hp is also offered. The Impala delivers a comfortable ride and offers decent fuel economy. Inside, key features include a standard OnStar telematics, optional Bluetooth, and leather upholstery (for LTZ). Noteworthy safety features include front-seat side airbags, full-length side curtain-type airbags, antilock brakes, stability control, and traction control. Despite being a mainstream full-size sedan, the Impala's tech and interior often lagged behind its contemporaries.
