Compare the2023 Cadillac CT4-VVS 2022 Infiniti Q50

Both the CT4-V and Q50 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 Q50’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.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the CT4-V are reminded to check the back seat if they opened the rear door before starting out. The Q50 doesn’t offer a back seat reminder.

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 Q50 doesn’t offer knee airbags.

The CT4-V’s standard pretensioning seatbelts also sense rear collisions and remove slack from the front seatbelts to help protect the occupants from whiplash and other injuries. The Q50 doesn’t offer a whiplash protection system.

Both the CT4-V and the Q50 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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.

There are almost 3 times as many Cadillac dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the CT4-V’s warranty.

The battery on the CT4-V is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the CT4-V’s battery 20 to 30 degrees cooler, its life is increased by years. The Q50’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Cadillac vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks Cadillac above average in initial quality. With 41 more problems per 100 vehicles, Infiniti is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Cadillac vehicles are more reliable than Infiniti vehicles. J.D. Power ranks Cadillac above average in long-term dependability. With 24 more problems per 100 vehicles in the first three years of ownership, Infiniti is rated below average.

The CT4-V’s standard 2.7 turbo 4-cylinder produces 25 more horsepower (325 vs. 300) and 85 lbs.-ft. more torque (380 vs. 295) than the Q50’s standard 3.0 turbo V6. The CT4-V’s 2.7 turbo 4-cylinder produces 30 lbs.-ft. more torque (380 vs. 350) than the Q50 Red Sport 400’s standard 3.0 turbo V6. The CT4-V Blackwing’s standard 3.6 turbo V6 produces 72 more horsepower (472 vs. 400) and 95 lbs.-ft. more torque (445 vs. 350) than the Q50 Red Sport 400’s standard 3.0 turbo V6.

As tested in Car and Driver the Cadillac CT4-V turbo 4 cyl. is faster than the Q50 Red Sport 400 (automatics tested):

On the EPA test cycle the CT4-V gets better mileage than the Q50:

An engine control system that can shut down some of the engine’s cylinders helps improve the CT4-V’s fuel efficiency. The Q50 doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the CT4-V (except Blackwing)’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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Q50 doesn’t offer an automatic engine start/stop system.

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 Q50 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 Infiniti Q50 (3). This means the CT4-V produces up to 23.4 pounds less smog-producing pollutants than the Q50 every 15,000 miles.

The CT4-V offers a manual transmission for better acceleration, control and sportiness. The Q50 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 a seven-speed automatic is available for the Q50.

The CT4-V’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Q50 doesn’t offer launch control.

For better stopping power the CT4-V Blackwing’s brake rotors are larger than those on the Q50:

The CT4-V stops much shorter than the Q50:

For better traction, the CT4-V has larger standard tires than the Q50 (235/40R18 vs. 225/50R18). The CT4-V Blackwing’s tires are larger than the largest tires available on the Q50 (F:255/35R18 & R:275/35R18 vs. F:245/40R19 & R:265/35R19).

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 Q50 Luxe’s standard 50 series tires. The CT4-V’s optional tires have a lower 35 series profile than the Q50 Red Sport 400’s 40 series front tires.

The CT4-V’s front to rear weight distribution is more even (52.3% to 47.7%) than the Q50’s (55.8% to 44.2%). This gives the CT4-V more stable handling and braking.

The CT4-V Blackwing handles at 1.01 G’s, while the Q50 Red Sport 400 pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

The CT4-V has a 1000 lbs. towing capacity. The Q50 has no towing capacity.

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Infiniti. J.D. Power ranks Cadillac second in service department satisfaction. With a 18% lower rating, Infiniti is ranked 9th.

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 Q50 does not have an oil pressure gauge.

The CT4-V offers an optional heads-up display that projects speed, tachometer, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Q50 doesn’t offer a heads-up display.

The CT4-V’s power parking brake sets with one touch and releases with one touch or automatically. The Q50’s parking brake has to be released manually.

The power windows standard on both the CT4-V and the Q50 have locks to prevent small children from operating them. When the lock on the CT4-V is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Q50 prevents the driver from operating the other windows just as it does the other passengers.

Optional air-conditioned seats in the CT4-V keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Q50 doesn’t offer air-conditioned seats.

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 Q50.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Cadillac CT4-V has a standard wireless phone charging system (Qi) in the center console. The Q50 doesn’t offer wireless personal charging.
