For enhanced safety, the front and rear seat shoulder belts of the Jaguar XJ 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 SRT doesn’t offer pretensioners for the rear seat belts.

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

The XJ 3.0 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The 300 SRT doesn’t offer all-wheel drive.

Both the XJ and the 300 SRT have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height-adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

The XJ comes with a full 4 year/50,000 mile basic warranty, which covers the entire car and includes 24 hour roadside assistance. The 300 SRT’s 3 year/36,000 mile basic warranty expires 1 year and 14,000 miles sooner.

The XJ’s corrosion warranty is 1 year and unlimited miles longer than the 300 SRT’s (6/unlimited vs. 5/100,000).

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

J.D. Power and Associates’ 2014 Initial Quality Study of new car owners surveyed provide the statistics that show that Jaguar vehicles are better in initial quality than Chrysler vehicles. J.D. Power ranks Jaguar second in initial quality, above the industry average. With 24 more problems per 100 vehicles, Chrysler is ranked 11th.

J.D. Power and Associates’ 2014 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Jaguar vehicles are more reliable than Chrysler vehicles. J.D. Power ranks Jaguar 13th in reliability. With 23 more problems per 100 vehicles, Chrysler is ranked 23rd.

On the EPA test cycle the XJ 5.0 Supercharged gets better fuel mileage than the 300 SRT (15 city/23 hwy vs. 14 city/23 hwy).

In heavy traffic or at stoplights the XJ’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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The 300 SRT doesn’t offer an automatic engine start/stop system.

The XJ has 2.3 gallons more fuel capacity than the 300 SRT (21.7 vs. 19.4 gallons), for longer range between fill-ups.

For better traction, the XJR’s tires are larger than the largest tires available on the 300 SRT (F:265/35R20 & R:295/30R20 vs. 245/45R20).

The XJ’s standard 275/40R19 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the 300 SRT’s standard 45 series tires. The XJR’s 265/35R20 front and 295/30R20 rear tires have a lower 35 series front and 30 series rear profile than the 300 SRT’s 45 series tires.

The XJ has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the 300 SRT, it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling Comparison

The rear suspension of the XJ uses air springs for a smoother, controlled ride than the 300 SRT, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The XJ has a standard automatic rear load leveling suspension to keep ride height level with a heavy load or when towing. The 300 SRT doesn’t offer a load leveling suspension.

The XJ has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The 300 SRT doesn’t offer variable-assist power steering.

The XJ’s front to rear weight distribution is more even (51.1% to 48.9%) than the 300 SRT’s (54% to 46%). This gives the XJ more stable handling and braking.

The XJL Supercharged handles at .87 G’s, while the 300 SRT pulls only .82 G’s of cornering force in a Road & Track skidpad test.

The Jaguar XJ may be more efficient, handle and accelerate better because it weighs about 200 to 500 pounds less than the Chrysler 300 SRT.

The design of the Jaguar XJ amounts to more than styling. The XJ has an aerodynamic coefficient of drag of .29 Cd. That is significantly lower than the 300 SRT (.334) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the XJ get better fuel mileage.

As tested by Road & Track, the interior of the XJL Supercharged is quieter than the 300 SRT:

The XJL has 2.7 cubic feet more passenger volume than the 300 SRT (109 vs. 106.3).

For enhanced passenger comfort on long trips the XJ L’s available rear seats recline. The 300 SRT’s rear seats don’t recline.

A low lift-over trunk design makes loading and unloading the XJ easier. The XJ’s trunk lift-over height is 28.5 inches, while the 300 SRT’s liftover is 30.1 inches.

To make loading and unloading groceries and cargo easier, especially for short adults or children, the XJ has a standard power trunk, which opens and closes automatically by pressing a button. The 300 SRT doesn’t offer a power trunk.

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

If the windows are left down on the XJ the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the 300 SRT can only raise the windows from inside the vehicle, with the ignition on.

The XJ’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 SRT Core’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The XJ offers available headlight washers to keep headlight output high. The 300 SRT doesn’t offer headlight washers.

The XJ 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 is only available on the 300 SRT Premium.

The XJ was chosen as one of Automobile Magazine’s “All Stars” in 2011. The 300 SRT hasn’t been picked since 2007.
