Finally - Jag XF

[MikeL]

From Autoexpress, looks like Jag finally have an oil burner to compete with the Germans:

The big cat is finally out of the bag! Jaguar has released the first pictures and full details of its new XF Diesel S, an oilburning flagship that combines class-leading performance with impressive fuel economy.

Due on sale in March, the newcomer is fitted with a new 3.0-litre V6 engine with 273bhp and a staggering 600nm of torque. Capable of a top speed of 155mph, and a 0-60mph sprint of 5.9 seconds the newcomer also promises to return 42mpg.
Meanwhile, CO2 emissions are 179g/km – that’s 10 percent less than the acclaimed 2.7-litre unit that this new engine replaces.

Power is transmitted to the road via the rear wheels, through an updated six speed automatic gearbox. Drivers can either select a fully automatic mode, or swap ratios via steering wheel mounted paddles.
To complete the package, XF Diesel S also gets 20 inch wheels, an aerodynamic boot lid spoiler and discreet ‘S’ badging.
Inside, the S gets sports seats, and a number of specification upgrades to the car’s satellite navigation and air-conditioning systems.

that's a powerful diesel at 275 hp ..

 

[JasM]

Impressive stuff.

The new XF V6 Diesel S – combining superb performance and excellent Fuel Economy - sets the pace with acceleration from 0-60mph in 5.9 seconds, a maximum speed of 155mph, yet delivers an average fuel consumption of 42mpg and CO2 emissions of 179g/km: Truly the best of both worlds!"

It looks like progress to me but I'm sure there are some that will feel aggrieved that it isn't a lazy V8 petrol engine turning out 300+g/km of Co2...

Doesn't it just show what the manufacturers can develop now they are bound by strict emission outputs.....

Interstingly it's almost exactly the same output per litre as Mercedes 2.2Cdi now.
Roll on 100 Bhp/Litre..:bannana:

This 'new' engine is of course a development of the existing 2.7 V6 diesel developed by Ford and PSA Peugoet Citroen. I've driven this engine in other models and been a bit underwhelmed by its low power and relatively high CO2 output.

This development seems to put those wrongs right! Will look forward to driving it with baited breath!

 

[pauldmaynard]

sounds very nice might buy one

Err no! This is a powerfull diesel

http://www.jcbdieselmax.com/html/car.php?subsection=11

About 150bhp/litre.
I must admit that the 30secs turbo lag could be a little difficult in traffic!

My S class motor has very similar figures to this new Jag engine, but with just a single turbo and does not exceed any critical exhuast gas temps.

The technology to do this all exists, but we have to wait for the manufacturers to validate their products. At least they are not in aircraft industry timescales!
In motorsport if you invent something in the week, it's on the car at the weekend

Its sure is about time Jag brought a competative diesel to the market place.

I find the 42mpg and the 179g/km CO2 bit hard to swallow as thats what my cdi gets day to day (and I make do with half the power). Its either one advanced engine, or a liability to go wrong. You can get 100bhp/litre diesels, just not in a brand of car you'd want to drive

I am not aggrieved its a big lazy petrol V8. I like choices and so long as the choice remains I remain happy. Some people like petrol engines....

 

[popuptoaster]

if its anything like the old S type diesel to drive they can keep it.

This is a powerful diesel too. 0 - 60 in 2 seconds.

 

[Mactech]

I haven't seen a quicker accelerating diesel than that!

 

[crockers]

I would be tempted.....if I was in the market......

Err No Check out this baby V24 diesel engine, quad turbo, 3400hp

Ford's are actually not that bad, i've driven a new focus , it was quite good fun to drive (only a 1.6) and was surprisingly comfortable. Although it doesn't have the prestige of a Mercedes.

 

[gary350]

My xf is the best ford I have ever driven, makes my mercs bland and boring.

Nothing against petrol engines..well apart from the lack of accessible torque and additional raspy noise, but try getting a 275Bhp petrol engine to achieve average emissions of 179g/km in a reasonable sized car.

Which production diesels achieve 100Bhp/litre.? I assumed you meant BMW so checked and find the most powerful to be the 535d at 89Bhp/litre, which is trailing both the Jag and Merc.

With proper design 100+Bhp diesels should present no issues at all, just a bit more investment and development.
Aftermarket tuners can achieve this and more already.
The engine won't give up, more likely the gearbox, but there is nothing that trying to save the last penny won't fix.

Imagine regular hatchbacks with 3 cylinder 140bhp engines producing under 100g/km...

 

[partsspecialist]

Thats a VERY flash mondeo!!
hahahahahahahaha

Joking aside, looks sweet.

535d is 3 litres and 286 bhp (previously 272 bhp).

New Jag is also 3 litres and 273 bhp.

Not sure that's really trailing?

I looked it up on Parkers and saw a figure of 268Bhp. I can now see 281Bhp as well, so thanks.
So MB and Jag at 91bhp/litre and BMW at 93Bhp/litre.

Neither is 100Bhp/litre though, so I wondered which car does produce that.

I can't wait to see some serious power outputs, it will be fun.
