Autocar - First for car news and reviews

Jaguar has facelifted the XF and introduced a new diesel-engined model – the Jaguar XF S – which enables the saloon to deliver 42mpg.

The Jaguar XF’s new engine is a development of the 2.7-litre AJ V6 that was jointly engineered with PSA and also powers the Land Rover Discovery.

Capacity has increased to 3.0 litres, and power is up by 33 per cent, from 207bhp to 272bhp. Torque increases to 420lb ft from 320lb ft, a 66 per cent hike. That makes the new unit more torquey than any of...Read the full article

So - when is this going into the Discovery? That car is BEGGING for the extra power and torque.

Will this also go into the Range Sport?

The reviewer has mixed things up with the turbos. In all twin-turbo engines the smaller one works at lower RPMs, while the larger one takes over higher up the rev range.

They should do a Daimler version........

Sounds like a great car but it won't add many sales.

Where's the four-cylinder 520d/E220 CDI competitor in the XF range? That's where the big hole is.

These are exactly the XF models Jaguar needs, surely this will now be the finest mid-sized saloon one can buy (apart from the Citroen C6, I'm still very partial to this car :) ).

 We can but hope there is a detuned version of the 2.7 on the way, giving improved emissions and consumption figures to go head to head with the likes of the 520d.

Is this a LRJ only engine or will the PSA group be getting the developments as well.  Would be great to see it in the C6 as well.

Jaguar has said in the past (as reported in Autocar) that since Aston is no longer in group it is looking to move upmarket and become more of a sportscar company like Porsche, so isn't looking to produce mass market underpowered cars like BMW and Merc any more. It has dropped any volume aspirations it used to have thankfully, and isn't trying to win over the fleet market in a big way, so we should only have cars with engines to match their sizes - back to the days of "proper" Jags. 

You may see a 2.5 Diesel XF when the X-Type finally dies, but I'd doubt you'll see engines much smaller. Jaguar is reputedly also looking to scale down its number of dealers dramatically, (compare how many Porsche has with Jaguar) and may have its job done for it if the Pendragon group goes into administration with its share price perilously low, and debts near £300m from the (in retrospect foolish) leveraged Reg Vardy Takeover, meaning a third of Jaguar dealers could go, which would massively improve profitability for the rest of the Jaguar dealer network.

Profitability of the dealer network doesn't really come in to this.  Jaguar need to produce cars the customers want, if they are competing with BMW and Mercedes or not.  With so many people down sizing either for CO2 or cost reasons, it is not going to be long before they have to consider offering a smaller, more efficient diesel version.

Unfortunately this is the way of the world at the moment, if we like it or not.

 Although I'm sure the line up would benefit from an entry level engine the revised unit does suggest you can have your cake and eat it:

THE NEW XF DIESEL S – In Brief

• The most advanced, powerful and efficient Jaguar diesel ever
• New 275PS high-performance XF Diesel S featuring Jaguar’s new AJ-V6D Gen III S 3.0-litre diesel engine delivers a massive 600Nm of torque
• 0-60mph in just 5.9 seconds, 50-70mph in just 3.2 seconds, a maximum speed of 155mph and yet combined fuel economy of just 42.0mpg – 12 percent better than the acclaimed 2.7-litre V6 diesel engine
  
• Emits just 179g/km – a 10 percent reduction in CO2. Conforms to EU5 emission regulations using conventional exhaust after-treatment
  
• 33 percent more powerful and 61 percent more torque from 1500rpm than the 2.7-litre V6 diesel

So you reckon BMW and Merc cars are underpowered? Particularly Merc with its monster engined AMG models?
