Jaguar : New 2.2-Litre diesel engine debuts in XF development mule

Jaguar has unveiled its most efficient engine yet in the form of a new 2.2-litre diesel unit. The new engine develops 187bhp and 332lbs/ft of torque and is capable of returning 52.3mpg on the combined cycle while emitting 149g/km of CO2.

Making its debut on UK roads fitted to a prototype development vehicle, the new four-cylinder 16-valve common rail diesel engine displaces 2,179 cc and is installed in a north-south configuration for the first time.  The new engine features a water-cooled turbocharger with low-friction pistons, new injectors and a new crankshaft.  The new configuration allowed Jaguar engineers to add a new oil pan and new electronic systems affecting the crankshaft to allow the new intelligent Stop-Start system to operate more efficiently.

Intelligent Stop-Start aims to reduce the prolonged time spent in the shutdown and start-up phase usually experienced in such systems.  The Jaguar system overcomes this partly through the inclusion of the new crankshaft sensor and fuel rail pressure holding system meaning the engine needs less time to restore drive through an innovative engine restart capability.

This is best demonstrated when approaching a busy roundabout – in situations where the driver briefly brings the vehicle to a stop only to move off again quickly. In conventional systems the engine needs to shutdown completely before restarting again, leading to often frustrating delays. The Jaguar system is able to restart the engine while it’s shifting down from as little as 400rpm meaning it does not need to come to a stop – drive is therefore restored more efficiently. The inclusion of the Stop-Start function is estimated to increase overall fuel efficiency between five and seven per cent.

Along with a new engine, the development vehicle debuts an advanced eight-speed ZF automatic gearbox.  With the seventh and eight ratios effectively acting as overdrive gears, the new gearbox allows the 2.2-litre engine to be optimised to deliver swift responses when required and effortless motorway cruising ability to ensure the ideal balance between efficiency and performance.  The sprint to 62mph takes 8.5 seconds before achieving a maximum speed of 140mph.

The high levels of refinement expected of modern Jaguars are retained with engineers putting particular emphasis on sound deadening around the engine and bulkhead as well as active engine mounts to reduce vibration.  The result is a 3dB reduction in cabin noise to make the car one of the most refined vehicles in its class.

The new powertrain will feature in a future XF production car with specifications and an estimated on-sale date being announced at the New York Auto Show next month.

    Good news, well done Jaguar.

  2. David 3500 says:

    This isn’t, then, the same PSA-derived unit as already fitted in the Freelander which, in SD4 form, produces 190PS?

    Mind you, even if it is, in a car as large as the XF, it offers good acceleration. It should give the lower end of the XF line-up a real sales boost. Good luck to it.

  3. Simon Woodward says:

    The news from JLR just seems to be getting better and better – all we need now is a new small Jaguar and a proper E-type replacement. Well done JLR!

  4. Jon says:

    That’s brilliant news. 🙂 Now what about the wagon?

  5. Two R8s says:

    We need XF Estates and ‘Tomcat’-like Coupes.

  6. Ross A says:

    Well, according to many in the press, this is a direct rival to the BMW 520d which also sports a 2.2 litre engine and it won’t be too far off the pace – where this car will score hands down, though, is with the ride and handling. Expect this to be a big executive fleet seller!

  7. Marinast says:

    Let us also not forget the XF range is undergoing a facelift so the whole range should recieve a boost.

  8. DaveH says:

    The engine is the same Ford-designed, PSA-based engine on which Jaguar has been working closely with Ford at their Dunton research facility. The engine will be produced alongside the SD4 on the Lion clean room line at Dagenham.

    The facelift is just visible in the pictures and shows the changes to lights, grille and bumper. A change to the interior is also due to be happening, although it will not be major.

  9. KenS Ken Strachan says:

    That suggests that the XF4D will have about the same power-to-weight ratio as my X-TYPE (150bhp) – in other words, drive with a light foot if you want to keep your licence! How much more power do you need?

  10. 406v6 406V6 says:

    The engine sounds very impressive. Jaguar just need to improve the traction in winter weather by fitting proper tyres. Every time the TV cameras featured a car stuck in the snow it was one of those (rear wheel drive with stupid tyres) “Ultimate Sliding machines”.

  11. A449 says:

    I’m pretty certain I saw this car a few days ago parked in a lay-by near Ross-on-Wye – I wondered what it was.

    Me too – very to near to the Government vehicle check point on the M50(?). That seems a popular place for car testers to play and is a nice discreet way to nip into South Wales or the Black Mountains.

  13. 820Tickford says:

    I saw one of these XF development prototypes in red and camo on the M6 near Coventry today. The car looked nice, from the little I could see!

  14. Ross A says:

    The pricing sounds about right… I saw a few Evoques in the Garden House Pub car park on Hagley Road in Birmingham over a period of a couple weeks last month.

    There seems to be lots of activity featuring JLR products at the moment and, with the good news that JLR is a major exporter again, things are looking hopeful.

  15. Paul says:

    We always seem to be talking about the death of the British Motor Industry. However, if you look at what Jaguar Land Rover are achieving along with the MINI at Cowley, a fair old chunk of what was British Leyland is in very rude health. All we have really lost is Austin-Morris. You could argue that the XF is effectively today,s SD1 but branded as a Jaguar.

    I believe that, if Tony Benn hadn’t brokered the deal between the original and successful British Leyland (Triumph/Rover/Trucks and Buses) with the lame duck that was BMC and that if Austin Morris had been allowed to go to the wall in 1968, the resultant British Motor Industry would have been pretty well what we now have today.

  16. Jonathan Carling Jonathan Carling says:

    @Paul
    Very true, and maybe MG are going to fill the Austin Morris void. Odd!

    BMW’s 520d is a 2.0-litre unit. Merc’s E 220 CDI and E 250 CDI use a 2.2-litre unit though.

    Jaguar says that the new iD4 engine, as the company calls it, is produced by PSA Peugeot-Citroen in France. 😉

  19. Ian says:

    The new 2.2-litre engine in the XF is mightily impressive. I got to drive it for the first time on Monday. It is paired to a ZF eight-speed automatic gearbox and is very slick in its operation. NVH is impressive, though lacks the overall smoothness of a V6, as you would expect.

    The finer details of the facelift are subject to an embargo – but all will be revealed in a couple of weeks. However, there’s one spyshot website which has already scooped a picture of the front end of the facelifted car.

  20. Ross A says:

    @Ian
    Hmm… Yep, I’ve just seen that. I’m not so keen on it myself as it looks a little too BMW-like, losing the sculpted hump over the main head lamp.

    The new one features a very contoured look which I think is fine especially if you like the BMW ‘flame’ design philosophy. Ignoring the facelift though, this car is still going to rock the boat in fleet sales. Good stuff…

  21. Andrew Elphick says:

    The facelifted MY12 Jaguar XF looks like a BMW 3-Series that’s been sat on… Here’s the leaked photograph referred to in Ian’s comment at #19 above.

  22. Timbo says:

    The headlights are much better on the facelifted version of the XF and are less like a Subaru’s – they were the worst feature of the current XF. However, the edge of the headlight, where presumably the indicator is, appears to be far too BMW-like.

    We just don’t want our Jaguars to look like Audi or BMW products. Jaguars need to look purposeful, slightly aggressive and have road presence, but what they don’t need is to look like Mr. Average’s Beemer. We still want that exclusive Jaguar look – that’s not, it seems, an easy achievement.

    Sadly, I still doubt the Clarkson brigade will choose the XF over the Bavarian stuff, though – thet are too busy following the crowd and buying what their neighbours and workmates buy. You could put a BMW badge on a t**d and some would buy it in these parts.

  23. James Cayton says:

    I think it’s about time that Jaguar came up with a 4×4 which gives really good fuel economy. They would blitz the market. Zap!

Have your say...
