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.
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.
Can you tell me, why Jaguar doesnt use V12 engines? Mercedes, BMW and other german cars have top model with this engine... and Jag which was using this engines in 80s and 90s has only V8.
I don't think the V-12 would have been able to meet European and American emissions regulations after the X300 XJ. The 4.2 supercharged V-8 in the new XJ gives it performance that compares quite nicely with its 12-cylinder rivals but for less money.
The old V12, while highly successful and exceptionally refined, was a bit low tech. With all the new manufacturing processes available to Jaguar these days, I think a properly constructed 12 could provide plenty of power, and wouldn't need a supercharger. I've always felt that forced induction was just not the Jaguar style; it looks too much like a last ditch attempt for more power. And let's face it, without it's supercharger, the current AJV8 is simply anemic.
Why doesn't Jaguar cut the rear doors off the current XJ8/XJR and give us another coupe; we haven't had such a car since the XJ12C back in the 1970's. Seems to me the only thing cooler than a supercharged 4 door XJR would be a 2 door model.
the above vehicle was made by SVO. the red XJ40-C was on display at the International Classic Motor Show 2003, NEC Birmingham. I dont know whos work it is.
"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."
more stuff
"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."
