Just for clarification, the 6 cylinder Jaguar XJ6 that was introduced in 1988 was code named the XJ40. Now the V12 variant which was featured in this video was code named the X81. This X81 is one of the most rare and limited production V12 Jaguar sedans ever made. It was actually produced for 18 months - late 1993 and all through 1994 as previewed in this video. To find one of these Cat's today is a rare and beautiful find. The V12 in these cars were updated to the 6.0 liter V12 size from the previous 5.3 liter V12 in previous versions. The 6.0 liter was a proper sports sedan engine where the older 5.3 liter was more for quietness and luxury. If you even find one of these cars, buy it, because they will only go up in value and are a seriously fun car to drive. Sir Williams Lyons would be extremely proud of what his last car turned out to me.
This is incorrect information. Jaguar's last V12 sedan was not 1979, it was offered in the United States until 1992 for Christ's sake! Until the 1994 model sedan shown in this video. Where did these people get their information?? And they were living in the relevant time period of this video!!??
I know I’ve seen XJ12’s at least as late as 1987 models that were definitely US market cars, and I’m a bit fuzzy on the 1988-1993 offering of the XJ12, but I agree it definitely did not disappear altogether between 1980 and 1993.
@@DrCharlesMontague The original commenter is correct. The series III XJ6 ran up to 1987 before the new Xj6 come out. But since they couldn't fit the mighty V12 into the engine bay of the new 1988 Jaguar Xj6, they continued the old series III Jaguar in V12 form only so that if by chance a buyer wanted a V12 sedan, they could get one. But by 1992 the old series III V12 sedan was really getting long in it's tooth and so it was discontinued until last 1993 when this car arrived on the scene. On sale for only 18 months, before the new X300(Xj6) came out, this is one of the most rare Jaguar sedans ever made.
You wish lol those 4 bangers are funny. It's the low gearing that's fooling you guys. That and the turbo spool sound 😂 These cars would cruise cross country at 150 mph all day long Try that with a turbo 4. It'll stop in a matter of hours due to over heating issues.
@@thewiseguy3529 lol, for real. Don’t get me wrong..I think that 12 would outlast the 4’s for sure. They put too much pressure through them to get the power. Plus I HATE the lag.
@@a.person7825 nothing takes the place of good ole naturally aspirated low end/mid torque. Turbos are great things! On diesels! Gasoline engines don't require them really. Definitely a plus on a diesel engine. Turbo gasoline engines still burn tons of fuel. You can't get power without the fuel. Think "V8 power crammed into 4 cylinders." Same amount of air capacity in the cylinder still needs the same amount of fuel. Turbo fills it all up with compressed air and tons of fuel is injected. Under load that is.......
It's engine friction, cost and packaging that has driven the move from V12s, V8s etc to 4 cylinders. I think Merc do/did a 4 cylinder that had about 340bhp from it in their AMG thing. I'm not a fan of 4 cylinder engines really. Turbos can use more fuel as they deliberately over-fuel in some heavier engine loading conditions to cool the turbo down... using fuel !

Had an XJ81 for 12 years , bought at 18 months old. Beautiful car but was feeling its age at the end with a few issues. Still my favourite car though.
great car and beautiful

12 cylinders. Anyone remember those? Lol. Now we have 2.0L 4’s that make the same output.

Ik now 12 cylinders are going away being replaced by batteries. It breaks my heart 💔
