It may be the base model, but the R-Sport comes very well equipped with standard 19-inch wheels, an adaptive and self-leveling suspension, adjustable drive modes, front and rear parking sensors, a rearview camera, automatic wipers, adaptive LED headlights with automatic high beams, a panoramic sunroof, power soft-close doors, a power trunklid, blind-spot monitoring with rear cross-traffic alert, lane departure warning with lane keeping assist, driver condition monitoring (RWD models only), auto-dimming mirrors, and keyless ignition and entry.

Inside the R-Sport you'll find leather upholstery, dual-zone automatic climate control, heated and ventilated seats, driver-seat memory settings, and a power-adjustable and heated steering wheel. A new larger 10-inch touchscreen anchors the infotainment system featuring navigation, Bluetooth, voice controls, Jaguar's InControl app suite, a 4G Wi-Fi hotspot, 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 upgraded front seats with massage functions, front passenger-seat memory settings, four-zone climate control and power rear sunshade. Other notable options include a surround-view camera, 360-degree parking sensors, an automatic parking system (RWD models only), adaptive cruise control, an upgraded Meridian sound system, and a heated 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 get the features from the Comfort package as standard. 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 footrests as well as massage and memory functions, extra-cushy winged headrests for all seats, power rear side-window sunscreens, fold-down tray tables and a rear-seat entertainment system.

The V8-powered Supercharged trim, again available in both the 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 R-Sport and Portfolio options are also available on the Supercharged model.

Topping the range is the fire-breathing XJR575 models with 25 more horsepower on tap compared to last year's XJR model. If that isn't enough to get excited, you also receive exclusive 20-inch wheels, XJR575-specific exterior and interior body details, a carbon-fiber engine cover, 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, aluminum paddle shifters, a heated steering wheel, a suede headliner and unique carbon-fiber interior trim. But due to the XJR's performance focus, you unfortunately lose the massaging seats, and the Premium Rear Seating package and the upgraded Meridian stereo are not available.
