The current Jaguar XJ has not been crash-tested by either the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS). This isn't an indicator that the car is necessarily unsafe, but instead a likely side effect of its expensive, low-volume nature. We've given the XJ high safety marks because of its construction techniques--the panels are glued and riveted together for a very strong passenger cell, much in the same way airplanes are constructed--as well as an extensive complement of safety gear.
The 2015 Jaguar XJ has most, but not all, of the techiest in-car safety features found in competitors. All models have the mandatory airbags and stability control--and in the XJ's case, the stability system has a sport mode that forgives some wheelspin, just in case the driver wants to play around with available grip.
For advanced features, the XJ gets a standard rearview camera, which augments a view that's a little compromised by those big roof pillars and short backlight. There's also a blind-spot alert system that blinks a light in the sideview mirrors when cars approach in adjacent lanes. Adaptive cruise control is an option, as are automatic and adaptive headlights. What you won't find in the XJ are things like night vision or lane-keeping systems, features now available on most of the luxury competition.
Available all-wheel drive gives the slushy states a realistic alternative to the all-weather versions of the luxest Mercedes, BMW, and Audi sedans. It's offered only on the six-cylinder XJ, though, in both the short- or long-wheelbase models. The system has a front:rear torque bias of 10:90 in normal driving, and 30:70 in its winter mode. It can apply as much as 50 percent of torque to the front wheels while it's sorting out available traction. Jaguar points out that this is a system for winter traction, not for additional high-performance in dry conditions; the company believes in keeping it rear-wheel-drive for that, as evidenced by the high-po XJR.
