New aluminum Jaguar XJ

The new XJ's aluminum chassis is 40 % lighter than if it were steel. It is also 60 % stiffer than its steel predecessor.















The 2005 Jaguar Super V8 is shown below and is the flagship XJ. It weighs over 800 pounds less than a BMW 760Li.

The new XJ uses magnesium in the seat frames.

"The complete body with weighs 650 pounds compared with an estimated 1,058 pounds for the same car in steel, 952 pounds for a Mercedes-Benz S-class, and 955 pounds for a 7-series BMW."

The long-wheelbase 2005 XJ weighs 53 pounds more than than normal XJ yet is 5 inches longer.

Aluminum underbody components are fastened together with aerospace-grade epoxy adhesives and some 3,200 self-piercing rivets to create the new XJ's chassis.

"The complete body with paint weighs 650 pounds compared with an estimated 1,058 pounds for the same car in steel, 952 pounds for a Mercedes-Benz S-class, and 955 pounds for a 7-series BMW."

"Thanks to advances in planetary gearset design, the ZF six-speed automatic gearbox is 24 pounds lighter, 2.0 inches shorter, and has 30 percent fewer parts than the five-speed unit in the outgoing XJ8."

for the XJR and Super V8...

"Front suspension knuckles are also shaped differently from the standard model to provide adequate clearance for significantly larger brake rotors and calipers."

- from The Inside Guide to the all-new aluminum Jaguar XJ by Automobile Magazine

The new XJ's wheels are pushed out to the corner's, like the 1968 XJ. The previous XJ had a lot of front and rear overhang.

The new XJ's outer headlights are larger than the inner headlights, like the 1968 XJ. The previous XJ's headlights were the same size.

The new XJ has a curve in its rear door, like Jaguars of the 50s and 60s. The previous XJ did not have a curve in its rear doors.

The new XJ may not look totally different from the previous XJ, but the Porsche 911's styling hasn't changed much over the years.

Jaguar uses magnesium for a cross-car beam that supports the dashboard and instrument panel. It is used with aluminum to create a lightweight steering column.

The new XJ is roughly 26 % bigger than the previous steel XJ yet the weight is kept down.

All 2006 XJs have more powerful brakes than 2004-2005 XJs. Supercharged XJs no longer use Brembo brakes, but the calipers are now floating.

2006 normally-aspirated XJs:

Front: 12.83 x 1.18 in. ventilated discs, floating cast iron calipers

Rear: 12.83 x 0.79 in. ventilated discs, floating aluminum calipers with integral park brake caliper

2004-05 normally-aspirated XJs:

Front: Ventilated discs, 12.6 in x 1.18 in., sliding aluminum calipers

Rear: Ventilated discs, 11.3 in. x .79 in., aluminum calipers

2006 supercharged XJs:

Front: 13.98 in. x 1.26 in. ventilated discs, floating composite aluminum and cast iron four calipers

Rear: 12.83 in. x 0.79 in. ventilated discs, floating aluminum calipers with integral park brake caliper

2004-05 supercharged XJs:

Front: Brembo ventilated R Performance discs, 14.4 in. x 1.26 in., fixed aluminum four piston calipers

Rear: Brembo solid R Performance discs, 13.0 in. x .59 in., fixed aluminum four piston calipers

2006 supercharged XJs have 400 hp (new SAE [Society of Automotive Engineers] ratings) and 413 lb-ft of torque.

The addition of an acoustic laminate to the windshield and side glass of the 2006 XJ helps to reduce interior noise, while simultaneously increasing occupant safety by making "smash and grab" theft particularly difficult.

2006 normally-aspirated XJs have 300 hp and get 27 mpg on the highway.

2006 XJ shown below

X350 is the code name for the new XJ which went into production by around April 2003. It is the first aluminum Jaguar sedan. The X350 is the 7th generation XJ and the first one came out as a 1968 model.
