For enhanced safety, the front and rear seat shoulder belts of the Lexus IS have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chrysler 300 doesn’t offer pretensioners for the rear seat belts.

The IS’ 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.

The Lexus IS 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 300 doesn’t offer a front passenger side knee airbag.

The IS has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 300 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The IS offers optional Auto Rear Braking 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 IS’ 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 IS offers an optional Panoramic 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 IS 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. Only the 300 Touring L/S offers a blind spot warning system.

To help make backing out of a parking space safer, the IS 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 IS and the 300 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Lexus IS is safer than the Chrysler 300:

	IS	300
	Driver

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the IS, with its five-star roll-over rating, is 1.8% less likely to roll over than the 300, which received a four-star rating.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the IS its highest rating: “Top Pick Plus” for 2021, a rating granted to only 75 vehicles tested by the IIHS. The 300 is not even a standard “Top Pick.”

Warranty

The IS comes with a full 4-year/50,000-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 14,000 miles sooner.

Lexus’ powertrain warranty covers the IS 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 IS’ corrosion warranty is 1 year longer than the 300’s (6 vs. 5 years).

Reliability

For smoother operation, better efficiency and fewer moving parts, the engines in the IS have an overhead cam design, rather than the old pushrod design of the 5.7 V8 in the 300.

J.D. Power and Associates’ 2021 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than Chrysler vehicles. J.D. Power ranks Lexus third in initial quality, above the industry average. With 107 more problems per 100 vehicles, Chrysler is ranked 33rd, below the industry average.

J.D. Power and Associates’ 2021 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Lexus vehicles are more reliable than Chrysler vehicles. J.D. Power ranks Lexus first in reliability, above the industry average. With 85 more problems per 100 vehicles, Chrysler is ranked 29th.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Lexus vehicles are more reliable than Chrysler vehicles. Consumer Reports ranks Lexus third in reliability. Chrysler is ranked 19th.

Engine

The IS has more powerful engines than the 300:

	Horsepower
IS 350 F Sport 3.5 DOHC V6	311 HP
IS 500 5.0 DOHC V8	472 HP
300 3.6 DOHC V6	292 HP
300S 3.6 DOHC V6	300 HP
300 5.7 V8	363 HP

As tested in Motor Trend the IS 300 AWD 3.5 DOHC V6 is faster than the Chrysler 300:

	IS	300S	300 V8
Zero to 60 MPH	5.7 sec	6.4 sec	5.8 sec
Quarter Mile	14.3 sec	14.9 sec	14.2 sec
Speed in 1/4 Mile	97.6 MPH	97.1 MPH	n/a

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lexus IS higher (5 out of 10) than the Chrysler 300 (3). This means the IS produces up to 16.5 pounds less smog-producing pollutants than the 300 every 15,000 miles.

Brakes and Stopping

For better stopping power the IS’ front brake rotors are larger than those on the 300:

	IS	IS 500	300	300 V8/AWD
Front Rotors	13.2 inches	14 inches	12.6 inches	13.6 inches
Rear Rotors	11.7 inches	12.7 inches	12.6 inches	12.6 inches

The IS’ 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 IS stops much shorter than the 300:

	IS	300
60 to 0 MPH	110 feet	121 feet	Motor Trend
60 to 0 MPH (Wet)	141 feet	143 feet	Consumer Reports

Tires and Wheels

For better traction, the IS has larger standard tires than the 300 (235/45R18 vs. 215/65R17).

The IS 300’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the 300 Touring’s standard 65 series tires. The IS 350 F Sport/500’s 235/40R19 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 IS 300 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the 300 Touring.

Suspension and Handling

The IS offers an optional 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 IS 350 F Sport handles at .93 G’s, while the 300 pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The IS 350 F Sport executes Motor Trend’s “Figure Eight” maneuver 1.8 seconds quicker than the 300 (25.4 seconds vs. 27.2 seconds).

For better maneuverability, the IS’ turning circle is 3.2 feet tighter than the 300’s (34.2 feet vs. 37.4 feet). The IS AWD’s turning circle is 2 feet tighter than the 300’s (35.4 feet vs. 37.4 feet).

Chassis

The Lexus IS may be more efficient, handle and accelerate better because it weighs about 300 to 500 pounds less than the Chrysler 300.

The IS is 1 foot, 1.2 inches shorter than the 300, making the IS easier to handle, maneuver and park in tight spaces.

Cargo Capacity

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the IS 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 Lexus service is better than Chrysler. J.D. Power ranks Lexus second in service department satisfaction. With a 77% lower rating, Chrysler is ranked 29th.

Ergonomics

Unlike the driver-only memory system optional in the 300 Touring L/S, the IS offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The IS’ 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 IS’ 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 300 does not have an oil pressure gauge.

The IS’ power parking brake sets with one touch and releases with one touch or automatically. The 300’s parking brake has to released manually.

The IS’ 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 IS 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. (This window function must be activated by your Lexus service department.) The driver of the 300 can only close the windows from inside the vehicle, with the ignition on.

Consumer Reports rated the IS’ headlight performance “Very Good,” a higher rating than the 300’s headlights, which were rated “Poor” to “Good” (depending on model and options).

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 IS’ headlights were rated “Good” to “Acceptable” by the IIHS, while the 300’s headlights are rated “Poor.”

Economic Advantages

According to The Car Book by Jack Gillis, the IS is less expensive to operate than the 300 because typical repairs cost much less on the IS than the 300, including $1354 less for a muffler, $60 less for front brake pads and $528 less for front struts.

Recommendations

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