Compare the2023 Cadillac CT4-VVS 2023 Kia Stinger

Both the CT4-V and Stinger have child safety locks to prevent children from opening the rear doors. The CT4-V 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 Stinger’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.

The Cadillac CT4-V has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Stinger doesn’t offer a front passenger side knee airbag.

Over 200 people are killed each year when backed over by motor vehicles. The CT4-V Auto has standard Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Stinger doesn’t offer backup collision prevention brakes.

Both the CT4-V and the Stinger have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, 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, available all wheel drive and around view monitors.

The CT4-V’s corrosion warranty is 1 year and unlimited miles longer than the Stinger’s (6/unlimited vs. 5/100,000).

The CT4-V’s standard 2.7 turbo 4-cylinder produces 25 more horsepower (325 vs. 300) and 69 lbs.-ft. more torque (380 vs. 311) than the Stinger GT-Line’s standard 2.5 turbo 4-cylinder. The CT4-V’s 2.7 turbo 4-cylinder produces 4 lbs.-ft. more torque (380 vs. 376) than the Stinger GT2’s standard 3.3 turbo V6. The CT4-V Blackwing’s standard 3.6 turbo V6 produces 104 more horsepower (472 vs. 368) and 69 lbs.-ft. more torque (445 vs. 376) than the Stinger GT2’s standard 3.3 turbo V6.

On the EPA test cycle the CT4-V gets better mileage than the Stinger:

An engine control system that can shut down some of the engine’s cylinders helps improve the CT4-V’s fuel efficiency. The Stinger doesn’t offer a system that can shut down part of the engine.

The CT4-V has 1.1 gallons more fuel capacity than the Stinger (17 vs. 15.9 gallons), for longer range between fill-ups.

The CT4-V has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Stinger doesn’t offer a cap-less fueling system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Cadillac CT4-V higher (5 to 6 out of 10) than the Kia Stinger (3). This means the CT4-V produces up to 23.4 pounds less smog-producing pollutants than the Stinger every 15,000 miles.

The CT4-V offers a manual transmission for better acceleration, control and sportiness. The Stinger doesn’t offer a manual transmission.

A 10-speed automatic is standard on the Cadillac CT4-V, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Stinger.

For better stopping power the CT4-V Blackwing’s front brake rotors are larger than those on the Stinger:

The CT4-V’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.

The CT4-V stops much shorter than the Stinger:

For better traction, the CT4-V has larger standard tires than the Stinger (235/40R18 vs. 225/45R18). The CT4-V Blackwing’s tires are larger than the largest tires available on the Stinger (F:255/35R18 & R:275/35R18 vs. F:225/40R19 & R:255/35R19).

The CT4-V’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Stinger GT-Line’s standard 45 series tires. The CT4-V’s optional tires have a lower 35 series profile than the Stinger GT2’s 40 series front tires.

The CT4-V has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Stinger doesn’t offer vehicle monitored tire inflation.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the CT4-V can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Stinger doesn’t offer run-flat tires.

The CT4-V Blackwing handles at 1.01 G’s, while the Stinger AWD pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

The CT4-V executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the Stinger (25.4 seconds @ .73 average G’s vs. 26.8 seconds @ .67 average G’s).

The CT4-V is 3 inches shorter than the Stinger, making the CT4-V easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver while under full throttle, the interior of the CT4-V is quieter than the Stinger GT2 (79 vs. 84 dB).

The CT4-V has a 1000 lbs. towing capacity. The Stinger has no towing capacity.

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Kia. J.D. Power ranks Cadillac second in service department satisfaction. With a 46% lower rating, Kia is ranked 26th.

The CT4-V’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Stinger does not have an oil pressure gauge.

The CT4-V’s front and rear power windows all lower with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Stinger’s rear power window switches have to be held the entire time to open them fully.

The CT4-V offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Stinger.
