Spy Shots: Jaguar XK diesel under development
by Jonathon Ramsey on Dec 1st 2008 at 9:35AM 
The reports are true: a 3.0-liter diesel Jaguar XK is on the way. The new XK, long due for a serious refresh, will show up in 2009 with the minor addition of the JaguarDrive selector a la XF and the major addition of a diesel engine to boost fuel economy and sales, along with two new V8s. Since Jaguar's 2.7-liter V6, which puts out 204 hp and 320 lb-ft., is only getting bored out to 3.0 liters it probably won't match the numbers put up by BMW's 3.5-liter, at 286 hp and 427 lb-ft. But the larger lump should goose the horsepower number and seriously increase torque (we hope) at least to the level of Audi's 3.0-liter V6 diesel, which turns out 240 hp and 369 lb-ft.
If diesel economy and pump prices still don't register with you, there will still be two gas options to fuel the fires. The 4.2-liter V8 goes away to make room for the new 5.0-liter with 400 hp, and if you want whipped cream and cherries on top, hit Jaguar up for the supercharged XK-R with 500 hp.

BMW's 3.5 engine? Do you guys mean the 3.0L in the X5/335d?
I'm still hesitant about diesels in passenger cars in the U.S. but if they are more efficient - taking into account the extra diesel production effort and oil - is a good thing, especially since current ("clean") diesels emit less noxious gas than sparking counterparts.

In the US? Where does the article mention this is US bound, it's coming from CAR, the UK's leading car magazine, and Jag's diesel engines, unlike say Audi's which will be on sale in the Q7, A4, Q5, A5 shortly, aren't US 50 state compliant.
Per your bias against diesel engines in passenger cars, we're post Y2K now, get with the program.

Long overdue for a refresh? The car's been out barely 3 years. That's not overdue for a refresh, its right on time.

Yeah between that coment and the one about the ficticious BMW 3.5L, it sounds like the author had had a little too much holiday sauce when he wrote this.

BMW's largest diesel 6-cylinder is a 3.0 - so Jaguar could make the same numbers from a 3.0 PSA if they wanted. The current 2.7 already twin-turbo, but not sequential, as that would be more complicated on a V6 vs. BMW's I6.
But would they need to? The XK is aluminum space frame and lighter than a 6-series, so it would be as quick as a 635d without matching it's power output.

Wait... that will make it the XK6! Now all we need for this financial crisis is an inline four cylinder (as in LR2 Td4) and we will get an XK4.

It just goes to show that so-called experts on Autoblog can't be relied upon.
Every car enthusiast knows that the 35d engine in BMW's cars and 4x4's are a twin turbo 3.0-litre turbodiesel engine, in the same way that a 23d engine is a twin-turbo 2.0-litre, as found in the BMW 1 Series.
These kinds of mistakes mean that the entire articles loses credibility.
