The 2014 Impala offered two powertrains: a 3.6-liter V6 gasoline engine and a hybrid system that pairs a 2.4-liter four-cylinder with GM’s eAssist electric motor. In short, buyers could choose between a V6 for performance or a hybrid setup for improved fuel economy.
The following sections outline the two engine options, what they deliver in terms of performance and efficiency, and how they affected the Impala’s overall character in that model year.
Engine options
The Impala’s 2014 lineup included two powertrains: a traditional gasoline option and a hybrid option. The two powertrains are described below.
- 3.6-liter V6 gasoline engine
- 2.4-liter four-cylinder with eAssist hybrid system
Summary: the V6 emphasizes performance, while the hybrid prioritizes efficiency with a mild-hybrid setup.
Details by option
3.6-liter V6 gasoline engine: This option delivers strong performance for a full-size sedan, producing about 303 horsepower and 264 lb-ft of torque. It is paired with a conventional automatic transmission and front-wheel drive is standard (all-wheel drive was not offered on the Impala for 2014).
2.4-liter four-cylinder with eAssist hybrid system: The hybrid configuration uses a 2.4-liter Ecotec four-cylinder along with GM’s eAssist electric motor to provide a combined output of roughly 182 horsepower. This setup focuses on efficiency rather than outright speed and is not a plug-in hybrid.
How to tell which engine is in your Impala
For a specific vehicle, check the window sticker or the VIN decoding to confirm the powertrain. The two mainstream options for the 2014 model year were the 3.6L V6 and the 2.4L eAssist hybrid.
Summary
In 2014, the Chevrolet Impala could be equipped with either a 3.6-liter V6 gasoline engine or a hybrid system that combines a 2.4-liter four-cylinder with GM’s eAssist electric motor. The choice between them balanced performance and efficiency for buyers of that redesigned full-size sedan.
