Safety

Both the Impala and G80 have child safety locks to prevent children from opening the rear doors. The Impala has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The G80’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

Compared to metal, the Impala’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Genesis G80 has a metal gas tank.

Both the Impala and the G80 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Chevrolet Impala is safer than the Genesis G80:

Warranty

There are over 8 times as many Chevrolet dealers as there are Genesis dealers, which makes it much easier should you ever need service under the Impala’s warranty.

Reliability

The Impala has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The G80 doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.

To reliably start during all conditions and help handle large electrical loads, the Impala has a standard 800-amp battery. The G80 only offers a 740-amp battery.

Engine

As tested in Consumer Reports the Chevrolet Impala V6 is faster than the G80 3.8:

Fuel Economy and Range

On the EPA test cycle the Impala V6 gets better fuel mileage than the G80 3.8 RWD (19 city/28 hwy vs. 18 city/26 hwy).

In heavy traffic or at stoplights the Impala 4 cyl.’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The G80 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Chevrolet Impala uses regular unleaded gasoline. The G80 3.3T Sport requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

Brakes and Stopping

The Impala stops much shorter than the G80:

Consumer Reports

Tires and Wheels

For better ride, handling and brake cooling the Impala Premier offers optional 20-inch wheels. The G80’s largest wheels are only 19-inches.

Suspension and Handling

The Impala’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The G80 doesn’t offer drift compensation steering.

Chassis

The Chevrolet Impala may be more efficient, handle and accelerate better because it weighs about 450 to 900 pounds less than the Genesis G80.

The Impala 4 cyl. uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The G80 doesn’t offer active noise cancellation.

As tested by Car and Driver while at idle, the interior of the Impala LT is quieter than the G80 5.0 (38 vs. 39 dB).

Passenger Space

The Impala has .1 inches more front legroom and 4.8 inches more rear legroom than the G80.

Cargo Capacity

The Impala has a much larger trunk than the G80 (18.8 vs. 15.3 cubic feet).

The Impala’s standard rear seats fold to accommodate long and bulky cargo. The G80 doesn’t offer folding rear seats, only a ski pass-through.

Towing

The Impala has a 1000 lbs. towing capacity. The G80 has no towing capacity.

Ergonomics

Consumer Reports rated the Impala’s headlight performance “Good,” a higher rating than the G80’s headlights, which were rated “Poor.”

Optional air-conditioned seats in the Impala Premier keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The G80 only offers an air-conditioned driver’s seat.

The Impala offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The G80 doesn’t offer a house-current electrical outlet.

Economic Advantages

Insurance will cost less for the Impala owner. The Complete Car Cost Guide estimates that insurance for the Impala will cost $1830 to $7690 less than the G80 over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Chevrolet Impala will be $10045 to $26014 less than for the Genesis G80.

Recommendations

Both are recommended, but Consumer Reports® chose the Chevrolet Impala as its “Top Pick,” the highest scoring vehicle in its category, based on reliability, safety and performance.

The Chevrolet Impala outsold the Genesis G80 by over seven to one during 2018.
