Though it's the base model, the R-Sport comes very well equipped with standard 19-inch wheels, an adaptive and self-leveling suspension, driver-adjustable steering and throttle settings, shift paddles, front and rear parking sensors, a rearview camera, automatic wipers, automatic adaptive LED headlights with automatic high beams, LED taillights, a panoramic sunroof, power soft-close doors, a power trunklid, blind-spot monitoring with rear cross-traffic alert, auto-dimming mirrors, and keyless ignition and entry.

Inside the R-Sport you'll find leather upholstery, dual-zone automatic climate control, heated and cooled seats across the board, eight-way power front seats (with four-way power lumbar adjustment), driver-seat memory settings, and a power-adjustable and heated tilt-and-telescoping steering wheel. An 8-inch touchscreen anchors the infotainment system featuring navigation, Bluetooth phone and audio connectivity, voice controls, the InControl app suite, a Wi-Fi hot spot and a 14-speaker Meridian audio system with a satellite and HD radio, a CD player, digital music storage and a USB connection.

Options and packages available for the R-Sport include the Comfort package that adds 14-way power front seats with massage functions, front passenger-seat memory settings and four-zone climate control. The Parking Assist package includes a surround-view camera, 360-degree parking sensors and, for rear-drive models only, an automatic parking system. The Illumination package adds LED rear reading lights and blue illumination surrounding the front and rear air vents, on the door tread plates and the trunk finisher. Stand-alone options include adaptive cruise control, an upgraded stereo, a heated windshield and a wood-and-leather steering wheel.

The Portfolio model is the equivalent base trim of the long-wheelbase XJL. In addition to the 5 inches of rear legroom gained, you'll also get upgraded leather upholstery, standard four-zone automatic climate control, 14-way power-adjustable front seats with massage functions, rear LED reading lights, an electric rear window sunscreen and manual rear-side-window sunscreens.

The options list for the Portfolio is similar to the R-Sport, with the addition of a Premium Rear Seat package that includes reclining rear seats with memory function and footrests, extra cushy winged headrests (for the front and rear seats), electric rear side-window sunscreens, fold-down tray tables and a rear-seat entertainment system.

The V8-powered Supercharged trim, again available in both regular- and long-wheelbase, includes the Portfolio model's standard equipment, along with unique exterior trim, an active locking rear differential, tauter suspension tuning, 20-inch wheels with performance tires and larger brakes. All of the XJL Portfolio options are also available on the Supercharged model.

Topping the range is the fire-breathing XJR models with 550 horsepower on tap. If that isn't enough to get excited about, you also receive exclusive 20-inch wheels, premium paint colors (an extra-cost option on lesser XJs), R-specific suspension tuning, an active exhaust system (varying the amount of exhaust noise), sport seats, a heated steering wheel and unique interior trim. Due to the XJR's performance focus, however, you unfortunately lose the massaging seats, and the Premium Rear Seating package and the upgraded Meridian stereo are not available.
