Tweaked XF gets an extra 65bhp and 100lb ft from new oil-burner
29 December 2008

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 its rivals apart from the BMW 535d.

The new engine means that the Jaguar XF S, as the new diesel model will be called when it arrives in dealerships in March, can hit 60mph in 5.9sec, 1.8sec faster than the old 2.7-litre diesel. The car’s CO2 emissions fall from 199g/km to 179g/km.

Jaguar’s engineers have upgraded the engine’s forced induction system. Up to 2800rpm the larger of the two turbos does all the work, at which point the smaller unit kicks in. Jaguar claims that this system improves efficiency and reduces fuel consumption.

Along with the 272bhp engine, there will also be a 237bhp version with the same fuel consumption and CO2 emissions, although that model’s 0-60mph time is increased to 6.7sec.

The new diesel Jaguar XF S gets 20-inch wheels and a boot lid lip spoiler to help distinguish it from other XFs.

Jaguar is also adding a Portfolio model to the XF range, which will get a similar treatment to the XK and XF Portfolios; expect bespoke interior trim and colours, including lots of leather, and exterior tweaks such as polished aluminium wing vents.

Jaguar will also upgrade its petrol V8s in 2009, kicking off with a new 5.0-litre engine that’s due to be unveiled in the XFR super-saloon at next month’s Detroit motor show. Equipped with a supercharger, this engine produces 503bhp.

The Jaguar XF is a sublime British executive saloon. It has a tremendous interior and even greater dynamics

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

29 December 2008

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.

29 December 2008

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.

 

 

It's all about the twisties........

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
