Compare the2025 Genesis G70VS 2023 Kia Stinger

The G70 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Stinger doesn’t offer front seat center airbags.

Both the G70 and the Stinger have standard driver and passenger frontal airbags, front 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, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and around view monitors.

The G70’s corrosion warranty is 2 years and unlimited miles longer than the Stinger’s (7/unlimited vs. 5/100,000).

Genesis pays for scheduled maintenance on the G70 for 3 years and 36,000 miles. Genesis will pay for oil changes, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Kia doesn’t pay scheduled maintenance for the Stinger.

The G70 3.3T’s standard 3.3 turbo V6 produces 65 more horsepower (365 vs. 300) and 65 lbs.-ft. more torque (376 vs. 311) than the Stinger GT-Line’s standard 2.5 turbo 4-cylinder.

As tested in Motor Trend the G70 3.3T 3.3 turbo V6 is faster than the Stinger GT2 3.3 turbo V6:

On the EPA test cycle the G70 gets better mileage than the Stinger:

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Genesis G70 higher (4 to 5 out of 10) than the Kia Stinger (3). This means the G70 produces up to 16.5 pounds less smog-producing pollutants than the Stinger every 15,000 miles.

For better stopping power the G70’s brake rotors are larger than those on the Stinger:

The G70’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the Stinger GT-Line are solid, not vented.

For better traction and acceleration, the G70 has larger rear tires than the Stinger (255/35R19 vs. 225/45R18).

The G70’s 225/40R19 front and 255/35R19 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the Stinger GT-Line’s standard 45 series tires.

For better ride, handling and brake cooling the G70 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Stinger GT-Line.

The G70 handles at .94 G’s, while the Stinger pulls only .85 G’s of cornering force in a Motor Trend skidpad test.

The G70 executes Motor Trend’s “Figure Eight” maneuver 1.9 seconds quicker than the Stinger (24.9 seconds @ .77 average G’s vs. 26.8 seconds @ .67 average G’s).

For better maneuverability, the G70’s turning circle is .4 feet tighter than the Stinger’s (36.3 feet vs. 36.7 feet). The G70 AWD’s turning circle is .7 feet tighter than the Stinger AWD’s (37.7 feet vs. 38.4 feet).

The G70 is 5.8 inches shorter than the Stinger, making the G70 easier to handle, maneuver and park in tight spaces.

The design of the Genesis G70 amounts to more than styling. The G70 has an aerodynamic coefficient of drag of .28 Cd. That is lower than the Stinger (.3) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the G70 get better fuel mileage.

The front grille of the G70 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Stinger doesn’t offer active grille shutters.

As tested by Car and Driver, the interior of the G70 is quieter than the Stinger GT2:

The G70 has 2.1 cubic feet more passenger volume than the Stinger (95.9 vs. 93.8).

The G70 has 1.5 inches more front headroom and 1.7 inches more rear headroom than the Stinger.

The G70’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Stinger’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the G70 the driver can close them all from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the Stinger can only close the windows from inside the vehicle, with the ignition on.

Consumer Reports rated the G70’s headlight performance “Good,” a higher rating than the Stinger’s headlights, which were rated “Fair.”

Insurance will cost less for the G70 owner. The Complete Car Cost Guide estimates that insurance for the G70 will cost $590 less than the Stinger over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Genesis G70 will be $1701 to $13732 less than for the Kia Stinger.

Motor Trend performed a comparison test in its August 2020 issue and the Genesis G70 won out over the Kia Stinger AWD.

The G70 was chosen as a Car and Driver’s “Top Ten” for 2019. The Stinger has never been chosen by Car and Driver in their “10Best” issue.

Motor Trend selected the G70 as their 2019 Car of the Year. The Stinger has never been chosen.

A group of representative automotive journalists from North America selected the G70 as the 2019 North American Car of the Year. The Stinger has never been chosen.

The Genesis G70 outsold the Kia Stinger by over two to one during 2023.
