Compare the2024 Infiniti Q50VS 2023 Chrysler 300

The Q50 Red Sport 400’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 300 doesn’t offer pre-crash pretensioners.

Over 200 people are killed each year when backed over by motor vehicles. The Q50 has standard Back-up Collision Intervention that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 300 doesn’t offer backup collision prevention brakes.

The Q50’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the 300.

The Q50 has a standard Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The 300 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The Q50 has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. Only the 300 S/Touring L offers a blind spot warning system.

To help make backing out of a parking space safer, the Q50 has standard Rear Cross Traffic Alert and Back-up Collision Intervention automatically engages the brakes to help avoid a collision. Only the 300 S/Touring L offers Rear Cross Path Detection and the 300’s Rear Cross Path Detection does not include automatic braking.

Both the Q50 and the 300 have standard driver and passenger frontal airbags, front side-impact 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 and available all wheel drive.

Infiniti’s powertrain warranty covers the Q50 1 year and 10,000 miles longer than Chrysler covers the 300. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the 300 ends after only 5 years or 60,000 miles.

The Q50’s corrosion warranty is 2 years longer than the 300’s (7 vs. 5 years).

Infiniti pays for scheduled maintenance on the Q50 for 3 years and 36,000 miles. Infiniti will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Chrysler doesn’t pay scheduled maintenance for the 300.

For smoother operation, better efficiency and fewer moving parts, the engines in the Q50 have an overhead cam design, rather than the old pushrod design of some of the engines in the 300.

Power ranks Infiniti higher than Chrysler.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Infiniti vehicles are more reliable than Chrysler vehicles. Consumer Reports ranks Infiniti 17 places higher in reliability than Chrysler.

As tested in Consumer Reports the Infiniti Q50 3.0 is faster than the Chrysler 300 V6:

On the EPA test cycle the Q50 gets better mileage than the 300:

The Q50 has 1.5 gallons more fuel capacity than the 300 (20 vs. 18.5 gallons), for longer range between fill-ups.

The Q50’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 300 are solid, not vented.

The Q50 stops much shorter than the 300:

For better traction, the Q50 has larger standard tires than the 300 (225/50R18 vs. 215/65R17).

The Q50 Luxe’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the 300 Touring’s standard 65 series tires. The Q50 Red Sport 400’s 245/40R19 front and 265/35R19 rear tires have a lower 40 series front and 35 series rear profile than the 300’s optional 45 series tires.

For better ride, handling and brake cooling the Q50 Luxe has standard 18-inch wheels. Smaller 17-inch wheels are standard on the 300 Touring.

The Q50 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 300 doesn’t offer vehicle monitored tire inflation.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the Q50 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The 300 doesn’t offer run-flat tires.

The Q50 Sport’s optional 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 300 doesn’t offer drift compensation steering.

The Q50 Red Sport 400 handles at .88 G’s, while the 300 pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the Q50’s turning circle is .7 feet tighter than the 300’s (36.7 feet vs. 37.4 feet).

The Infiniti Q50 may be more efficient, handle and accelerate better because it weighs about 250 to 350 pounds less than the Chrysler 300.

The Q50 is 9 inches shorter than the 300, making the Q50 easier to handle, maneuver and park in tight spaces.

To almost totally eliminate engine vibration in the passenger area, the Q50 has liquid-filled engine mounts. The liquid helps further dampen engine harshness. The 300 uses conventional solid rubber engine mounts.

The Q50 has .9 inches more front headroom and 2.7 inches more front legroom than the 300.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the Q50 offers cargo security. The 300’s non-lockable folding seat and non-lockable remote release defeat cargo security.

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Chrysler. J.D. Power ranks Infiniti 9th in service department satisfaction (above the industry average). With a 54% lower rating, Chrysler is ranked 31st.

The Q50’s standard Entry/Exit Assist raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the 300, and is not available on all models.

The Q50’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 300’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 Q50 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the 300 can only close the windows from inside the vehicle, with the ignition on.

The Q50’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The 300’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

The Q50’s LED headlights produce a whiter, brighter light (up to 3x) using five times less power than the 300’s standard projector halogen headlights and light instantly. LED lights also last over twenty times longer than halogen. The Q50’s LED headlights produce a white, bright light using less electricity than the 300’s optional xenon high intensity discharge (HID) headlights. HID headlights can be slow to reach full brightness or power cycle, causing issues when flashing them to signal other vehicles; LED headlights light instantly. LED lights also last about three to four times as long.

The Q50 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the 300.

According to The Car Book by Jack Gillis, the Q50 is less expensive to operate than the 300 because typical repairs cost much less on the Q50 than the 300, including $102 less for a water pump, $1180 less for a muffler, $46 less for front brake pads, $332 less for front struts and $3 less for a timing belt/chain.

Consumer Reports® recommends both the Infiniti Q50 and the Chrysler 300, based on reliability, safety and performance.
