SEDONA, AZ – Add the Jaguar XF midsize sedan to the list of the British brand’s models making the leap to aluminum-intensive construction, from its lightweight chassis to body-side panels pressed from a single sheet of the metal alloy.

On sale in the U.S. now, the XF slots between the entry-level ’17 XE sports sedan and the flagship fullsize ’16 XJ luxury sedan. With the addition of the XE to the lineup, the XF no longer needs to fill the niche from entry to midlevel in the Jaguar portfolio.

As a result, one of the biggest changes is that the XF’s base powertrain is now the supercharged 3.0L V-6 producing 340 hp. A 380-hp version of the same engine goes into the uplevel XF S, the first application of the higher-output V-6 in a Jaguar sedan. Both come with 8-speed automatic transmissions and are offered in rear- or all-wheel drive.

The previous XF line included a 2.0L turbocharged I-4 as the base powerplant which now is limited to duty in the entry-level XE sedan. The XE enters U.S. showrooms this spring, followed by the F-Pace, Jaguar’s first CUV.

All three models, XE, XF and ’17 F-Pace will be offered with a 2.0L, 180-hp, 317 lb.-ft. (430-Nm) I-4 Ingenium turbodiesel, starting with the XF in mid-year.

The XF’s move to a heavily aluminum-based chassis and body helps the sedan drop 265 lbs. (120 kg) compared with the ’15 model, despite a higher level of equipment and an extra 2 ins. (51 mm) in wheelbase to 116.5 ins. (2,960 mm). Overall, the 4-door is nearly identical in length at 195 ins. (4,954 mm) and height at 57.5 ins. (1,457 mm), but the added wheelbase improves rear seat legroom and headroom.

Styling evolves, with a shorter front overhang, a more coupe-like profile, added rear-quarter windows and an upright front fascia while maintaining a clear Jaguar family resemblance. Simple character lines emphasize that the lightweight body-side panels are stamped from one piece of aluminum.

Key chassis upgrades build on several proven Jaguar techniques and components, including an aluminum double-wishbone front suspension borrowed from the F-Type and foam-baffled aluminum unibody construction that yields a 28% increase in torsional rigidity, Jaguar says. Rear suspension is an integral link setup. Passive and adaptive dampers control suspension movement. 

Interior improvements center on the optional InControl Touch Pro infotainment system, featuring a 10.2-in. (259 mm) touchscreen which, thanks to a major upgrade in computing power, reacts considerably faster than Jaguar’s previous system. Advance driver-assistance capabilities, including lane-keeping assistance, adaptive cruise control and parking assistance, are available.
