If Jaguar's XF sedan nicely suits an executive with a flair for sportiness, the XJ ups the ante for C-suite level execs with its fluid styling, lightweight ride, and near-pinpoint handling. It's a vehicle that, in its long-wheelbase version, allows a senior executive to be driven, yet begs that same exec to sit behind the wheel.

For a large luxury sedan, the XJ is surprisingly nimble thanks to aluminum body panels it has been incorporating since the 2004 model year. The strategy delivers a sedan that's fun to drive, and remarkably fuel efficient for the category. We tested the 2016 XJL Portfolio with Jaguar's all-wheel drive system that delivers an EPA-rated 25 mpg on the highway, 17 mpg in the city, and 20 mpg combined.

The 2016 model year brought modest changes to the XJ, which has also seen use in the livery industry in the long wheelbase model. Jaguar refreshed its flagship by adding full LED headlights, new daytime running lights, and redesigned LED tail lights.

However, the significant changes come inside the cabin. Jaguar has added its InControl Touch Pro infotainment system, smartphone connectivity, a Wi-Fi hotspot, and 26-speaker Meridian Digital Reference audio system. The reworked 12.3-inch TFT instrument screen now offers full-screen navigation.

Jaguar offers two engine choices, including a 3.0L 340-hp supercharged V-6 or 5.0L V-8 that makes 470 hp. We tested the V-6, and it offered plenty of power to climb the hilly roads in the Los Angeles-area foothills without breaking a sweat.

Our tested model would retail for $86,700 and included optional electric rear side window blinds and the Parking Assist package equipped with 360-degree park distance control and a surround camera system.
