It boosted the supercharged 5.0-liter V-8's 503 horsepower to 542, jacked up torque by 41 lb-ft to 502 lb-ft, freed up the speed limiter from 155 mph to 186 mph (a metric-round 300 km/h), and shaved 0.4 seconds off the 0-60 mph time, to 4.2. It lowered the ride height by 0.4 inches, stiffened the front suspension uprights, and raised spring rates by 28 percent front, 32 percent rear. This will cost you $35k-plus more than a garden-variety XKR coupe, the only bodystyle in which the XKR-S will be offered when it goes on sale this fall.

XFR: Along with the standard model, the XFR gets a new front bumper, grille, trunk finisher and a more luxurious interior. The "J-Blade" daytime running lights now are light-emitting diodes. The XFR comes with a horizontal chrome side power vent. With the same 503-horsepower engine as the standard XKR, the XFR is 0.1-seconds quicker in its 0-60 mph time (manufacturer's estimate). On the road, it "drives" smaller than the XKR, with very nicely balanced handling. If/when Jaguar does an XFR-S, CTS-v, M5 and XKR-S had better watch out.
XJ Supersport: The aluminum-intensive XJ weighs just 2.2 pounds more than the XF, so the Supersport, with the XFR/XKR's 503-horsepower supercharged V-8, matches the XFR's 4.7-second 0-60 mph time (manufacturer's estimate). Despite all that, Jaguar has wisely chosen not to stiffen up the suspension, so it's no XJR. Our testing of a right-hand-drive model was limited to the Algarve circuit, where the luxury car leaned cushily into every turn. It's reminiscent of those classic British sports car races in which Jag Mk IIs lean into corners that MGs, Austin-Healeys, and Triumphs take flat. The Supersport is for the executive who has lots of access to Autobahn-like roads.
