Comparison:Jaguar XF 2021 Vs. Jaguar XJ 2015

Dimensions

Dimensions befitting their classes, the Jaguar XJ outstretches the XF in length at 5130mm and wheelbase at 3032mm as compared to the XF's 4962mm and 2960mm, respectively, signifying more room for indulgences. However, width is where the XF at 1987mm betters the somewhat more slender XJ which measures 1899mm without mirrors. When including mirrors, the XJ spans wider at 2105mm. A matter of millimeters in height gives the XF, at 1456mm, a slightly more towering presence over the XJ's 1448mm. As for the nitty-gritty of negotiating narrows, the XF enjoys a minimal turning circle, advantageous when navigating tighter city corners; on the other hand, the XJ ranges between 11.90m and 12.90m, with longer wheelbase versions naturally requiring a broader berth. The edge here, in terms of sprightliness and urban compassing, goes to the XF.

Boot/interior

Dimensions aside, practicality peeks through when peeking into the boot: the XJ offers a reasonable 478 liters of cargo space, whereas the XF varies between 415 and 563 liters depending on the particular propulsion system beneath its bonnet—the Sportbrake estate model offering more for one's groceries and golf clubs. When seats retire from duty, the XF's space balloons to 722 liters to the windows, an accommodation the XJ does not counter. Both vehicles maintain an even keel with seating for 5 and Isofix points as standard. Jolly good on responsibilities, I'd wager, but the XF edges forward with the flexibility of space.

Engines/drivetrain

Under their bonnets resides the heart of the matter. Both Jags boast 8-speed transmissions, with the XF's engine choices starting from a humble 4-cylinder to more vigorous offerings. The XJ, conversely, begins with an aristocratic 6-cylinder and ascends to an 8-cylinder crescendo. When it comes to maximum velocity, the XJ leads the sprint with its engines ranging between 250 and a gusty 300 km/h, while the XF trails with a bracket of 230 to 250 km/h. As for power, the XF churns out between 150 to 221 kW of British bravado against the XJ's broader shoulders pushing from 221 to a muscular 423 kW. Torque figures also favor the XJ, easily surmounting the XF with a hefty 450 to 700 Nm contrasted against the XF's 365 to 430 Nm range. The XF, sporting a 1997cc engine, maintains a nod for efficiency. Horsepower and regality go to the XJ; however, for those seeking a blend of performance and panache, the XF holds its own.

Consumption/ecology

Talking tanks, the XF's fuel capacity is smaller, varying from 68 to 74 liters, somewhat less than the XJ's thirstier 77 to 80 liters—a clear sign of the XF's nod to a lighter thirst. CO2 emissions information is given for the XF only, which should, by virtue of its smaller displacement, suggest greener pastures. Tyre size presents as 245/45R18 for the XF versus a slightly more robust 245/45R19Y for the XJ, again illustrative of each model's intentions. Noise levels revealed an XF range of 66 to 69 dB—marginally less rumbustious than the XJ's 67 to 74 dB spectrum. As for consumption, the majestic XJ takes a firm hold of the reins with a combined (NEDC) fuel economy of 5.7 to 11.1 liters per 100km, and city consumption figures ranging from 7.0 to 16.2 liters per 100km. Clearly, efficiency begets the XF. Its smaller shoes and lighter sips at the petrol pond mean tighter turns at the pumps

Weight/towing

The scale tips slightly in favor of the lighter XF, with an empty weight (EU) ranging from 1735 to 1931 kg compared to the XJ's grander 1835 to 2026 kg. Both carry their own with a braked trailer capacity consistent across models, and share uniform figures for trailer without brakes, maximum roof, and towbar load limits. In essence, one could say the XF, though nimble, doesn't skive off hauling duties, yet clearly the XJ's additional heft sets expectations for sterling carriage potential. In the grand balance of weight and towing, heft equals capability, but the wise will weigh the XF's less portly figure against their real-world needs.
