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 and automatically apply the brakes to prevent a rear 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 and is only available on 300 Touring L/S.

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 which 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 Touring L/S offers a blind spot warning system.

To help make backing out of a parking space safer, the Q50 has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Only the 300 Touring L/S has a rear cross-path warning system.

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.

Warranty

The Q50 comes with a full 4-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The 300’s 3-year/36,000-mile basic warranty expires 1 year or 24,000 miles sooner.

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).

Reliability

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 the 5.7 V8 in the 300.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Infiniti vehicles are better in initial quality than Chrysler vehicles. With 61 fewer problems per 100 vehicles, JD Power ranks Infiniti higher than Chrysler.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Infiniti vehicles are more reliable than Chrysler With 12 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Infiniti higher than Chrysler.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Infiniti vehicles are more reliable than Chrysler vehicles. Consumer Reports ranks Infiniti 8 places higher in reliability than Chrysler.

Engine

The Q50 has more powerful engines than the 300:

	Horsepower	Torque
Q50 3.0 turbo V6	300 HP	295 lbs.-ft.
Q50 Red Sport 400 3.0 turbo V6	400 HP	350 lbs.-ft.
300 3.6 DOHC V6	292 HP	260 lbs.-ft.
300S 3.6 DOHC V6	300 HP	264 lbs.-ft.
300 5.7 V8	363 HP	394 lbs.-ft.

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

	Q50	300
Zero to 30 MPH	2.4 sec	3.2 sec
Zero to 60 MPH	5.7 sec	7.4 sec
45 to 65 MPH Passing	4.2 sec	4.6 sec
Quarter Mile	14.2 sec	15.8 sec
Speed in 1/4 Mile	103 MPH	94.8 MPH

Fuel Economy and Range

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

			MPG
Q50
	RWD	3.0 turbo V6	20 city/29 hwy
		Red Sport 400 3.0 turbo V6	20 city/26 hwy
	AWD	3.0 turbo V6	19 city/27 hwy
300
	RWD	5.7 OHV V8	16 city/25 hwy
	AWD	3.6 DOHC V6	18 city/27 hwy

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

Brakes and Stopping

For better stopping power the Q50 Red Sport 400’s front brake rotors are larger than those on the 300:

	Q50 Red Sport 400	300	300 V8/AWD
Front Rotors	14 inches	12.6 inches	13.6 inches
Rear Rotors	13.8 inches	12.6 inches	12.6 inches

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:

	Q50	300
70 to 0 MPH	165 feet	175 feet	Car and Driver
60 to 0 MPH	126 feet	137 feet	Consumer Reports
60 to 0 MPH (Wet)	131 feet	143 feet	Consumer Reports

Tires and Wheels

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.

Suspension and Handling

The Q50 offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The 300’s suspension doesn’t offer adjustable shock absorbers.

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).

Chassis

The Infiniti Q50 may be more efficient, handle and accelerate better because it weighs about 300 to 400 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.

Passenger Space

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

Cargo Capacity

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.

Servicing Ease

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.

Ergonomics

The Q50’s standard easy entry system 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 Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Q50’s available headlights were rated “Acceptable” by the IIHS, while the 300’s headlights are rated “Poor.”

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.

Economic Advantages

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.

Recommendations

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