The 2014 Impala offered two powertrains: a 3.6-liter V6 gasoline engine and, in the hybrid model, a 2.4-liter four-cylinder paired with an electric motor (eAssist) for a combined output of about 196 horsepower.
Engine options at a glance
The following sections detail the two main powertrains available in the 2014 Impala, outlining what each one delivers in terms of performance and efficiency.
Gasoline engine option
Key specifications for the 3.6-liter V6 option used in most 2014 Impala sedans.
- Displacement: 3.6 liters
- Configuration: V6
- Horsepower: about 303–305 hp
- Torque: around 264 lb-ft
- Transmission: 6-speed automatic
- Drivetrain: front-wheel drive (FWD)
- EPA fuel economy (approximate): ~18 mpg city / ~28–29 mpg highway
In summary, the V6 gasoline option provides robust acceleration and strong highway performance, at the cost of lower fuel economy compared with the hybrid.
Hybrid engine option
Key specifications for the 2.4-liter eAssist hybrid option, which combines a gasoline engine with an electric motor.
- Engine: 2.4-liter four-cylinder with eAssist hybrid system
- Combined horsepower: around 196 hp
- Transmission: integrated hybrid system (not a plug-in)
- Battery: small pack used to assist the gas engine; recharges during driving
- Fuel economy (approximate): typically higher than the V6, with EPA estimates commonly in the mid- to high-30s mpg combined
- drivability: designed for smoother acceleration and better city/highway efficiency, at the expense of some raw power compared with the V6
Overall, the hybrid emphasizes fuel savings and a quieter, smoother ride, with notably lower performance punch than the V6 variant.
Summary
For the 2014 Chevrolet Impala, buyers could choose between a muscular 3.6-liter V6 gasoline engine and a hybrid setup that uses a 2.4-liter four-cylinder with an eAssist electric motor. The V6 prioritizes performance and highway capability, while the hybrid prioritizes fuel efficiency. Both configurations were designed to suit different driving needs in a full-size sedan.
