Does this look like a 4,600-pound car? Now that you mention it... The F Sport package includes a more aggressive front fascia, side skirts, and forged 19-inch wheels.
With both the LS and XJ, the long wheelbase variant has more graceful, less stout proportions. Probably the LS's most elegant angle, high from the rear quarter. Lexus "L's" in the tail lamp.
F Sport interior also available with brown leather. Too much silver trim? Massive bi-level IP includes 12.3-inch display.
Mouse-like infotainment controller easier than a touchscreen, but not a knob. Can display two things at once, including the driving mode. (This road calls for firmer dampers.)
Cushy driver seat has larger bolsters in the F Sport. White perforations provide relief from black. Comfy cushion, and even in the regular wheelbase car there's a healthy amount of rear legroom.
Largest trunk in its class, despite a full-size spare beneath the floor. One industry-wide trend started by the original LS: a cover that totally hides the engine.
Remove the cover, and you still can't see the engine. F Sport includes huge 6-piston Brembo front calipers. But how many of these cars will visit a track?
