2011 Jaguar XJ Supersport review: 2011 Jaguar XJ Supersport

Although this audio system is as good as or better than anything found in executive sedans from Audi or Mercedes-Benz, the navigation system does not quite rise to those technological levels. The XJ's navigation system is very good, and ticks off all the right boxes, but the maps don't have the lush 3D detail that Audi provides. Instead, the XJ's maps look pale, with washed-out colors.

There are some 3D details, such as rendered landmark buildings. This system also shows traffic information and can reroute around traffic jams. When using voice command to enter destinations, you have to say each part of the address at separate prompts, unlike the latest voice command systems that let you say an entire address string.

This voice command system seemed very accurate when used to say the names of phone contacts. But, like many systems, when used with an iPhone it requires last name first.

No gas guzzling
The XJ Supersport is the most powerful model in Jaguar's current lineup, yet Jaguar boasts that it is not subject to a gas-guzzler tax. This feat was achieved partly through the car being a four-seater, but also its lightweight aluminum structure. The six-speed automatic and massive amounts of power let the engine run at only 1,500rpm even when cruising the freeway at 70 mph.

The fuel economy rates at 15 mpg city and 21 mpg highway. In testing, much of it spent exploiting the ridiculous amounts of power on tap, this car kept nicely in the midrange of its fuel economy, eventually turning in a comfortable 17.4 mpg average.


Direct injection and a supercharger give this V-8 510 horsepower.

A fast launch makes the XJ Supersport leap, then slow temporarily as its traction control reins it in, then leap forward again to exhilarating speed. But the supercharger whine and bass exhaust note largely go unnoticed by the driver, as the cabin is heavily insulated from exterior noise. The throttle is also well tuned to allow creeping through traffic without a lot of lurching, despite the 5-liter V-8.

Along with its 510 horsepower, the engine makes 461 pound-feet of torque. The supercharger plays a big part, but this engine also uses direct injection, giving it excellent efficiency.

The XJ Supersport's luxury character can be felt in the smooth ride, the way each wheel absorbs the imperfections of the roadway. It's a big, comfortable car, and the suspension is up to this task. Likewise, the steering wheel moves with little effort, making it easy to maneuver the big cat in a dense, urban environment. A rearview camera overlays trajectory lines, making bumper contact unnecessary when parking.

To engage the XJ Supersport's full performance mode, turn the drive selector dial past the D to the S, the sport mode. Then push in the checkered-flag button on the console, engaging competition mode, and all sorts of interesting things happen. Most noticeably, the LCD instrument cluster's background color goes from blue to an angry red. The throttle becomes more sensitive, ready to blast out more power, the suspension tightens up, and the traction control loosens.


The checkered-flag button near the drive selector puts the XJ in competition mode.

The suspension feel does not change dramatically--the car merely leans a little less in the corners, but still offers a comfortable ride. It corners very well in standard mode, but even better in competition mode. However, the XJ Supersport is not a hard-core sports car. The BMW 740i shows better composure when pressed hard. Jaguar has made more of a gentleman's sport sedan, not completely counteracting body roll.

That the traction control is loosened up in competition mode is apparent from the smell of rubber that pervades after going through a good set of turns. Disappointingly, the steering seems largely unaffected by the competition mode. It retains its luxury feel, offering little road feel, although it does seem to dial down its power assist as speeds increase.

In sum
The Bowers & Wilkins stereo system is a high point of the 2011 Jaguar XJ Supersport's cabin tech. But its phone and navigation systems are also full-featured. Adaptive cruise control and blind-spot detection add to the cabin tech package.

The XJ Supersport also has a lot to offer in the way of performance tech, with its powerful and efficient engine and active suspension. The competition mode really gives the car an edge. The only areas where it gets closer to the average are the steering, which could offer more sport tuning, and the transmission, which is limited to six gears.

The design of the car's interface is very good, much improved over the tech interface in other Jaguar models. And the car is a looker, with a big, distinctly Jaguar presence. The trunk is a little small, but otherwise the car has all the practicality of a big sedan.
