2018 Jaguar XJ

The previous year's XJR is superseded by the XJR575, taking the former's 550 horsepower and boosting it to 575 (for a top speed of 186 mph). Forward-collision mitigation, lane-keeping assistance and driver-fatigue monitoring become standard. All-Surface Progress Control is like a low-speed cruise control for slippery surfaces. The infotainment screen increases in size from 8 to 10.2 inches. The entry-level model receives an audio upgrade to a 20-speaker/825-watt Meridian system, and 4G connectivity brings Wi-Fi into the cabin.

At this point, someone who really wants an XJ and can't wait another year should just get the version they most desire.
