V6 turbodiesel model will break new ground for British firm's sports cars; interior takes XJ cues

Jaguar’s next-generation XK sports car will have a near-300bhp V6 diesel-powered variant in its line-up when it goes on sale around 2013.

The British manufacturer’s first ever diesel-powered sports car will get a 3.0-litre twin-turbo V6 to take on models like the BMW 635d, which has become the best-selling car in its class in the UK and Europe.

Jaguar XK 'could have grown'

In the new, lightweight aluminium-alloy XK, the punchy 3.0 turbodiesel promises a practical mix of performance and economy, with 0-60mph in under five seconds and a combined average of 30mpg within its grasp.

With V8 levels of torque on offer, the XK D could even become the ‘sleeper’ in the range, boasting giant-killing in-gear acceleration for strong point-to-point driving pleasure.

Significantly, as the market has shifted towards diesel sports cars, it should also help to lift the XK’s production average back up to 10,000 to 12,000 units per year by exposing the XK to a large new market segment.

To refresh the Jaguar sports car concept, the XK will feature all-new sheetmetal and a new grille design that will ditch today’s ‘Spitfire wing’ oval shape, which dates back to the E-type of the 1960s.

This traditional shape will be dropped for two reasons. Firstly, it can’t easily be expanded to make a bolder front-end statement. “It just looks wrong when it’s stretched,” said one insider. Secondly, the oval shape has proved to be less of a success overseas, where research shows it can be confused with other brands’ grilles.

Instead, Jaguar is deriving a new shape from the oblong design launched on the XF, but with its own unique characteristics. “The studio has explored dozens of variations. It’s just a matter of choosing the right one,” said another insider.

The XK’s exterior sheetmetal is also expected to move Jaguar design further forward again, just as today’s Ian Callum-designed model did when it was launched in 2006. Although the final styling still has to be chosen, the favoured sketches are understood to feature crisper metalwork and more developed body surfacing.

As with today’s car, both hard-top coupé and open-top convertible body styles will be available. The cabrio will retain a soft-top roof for packaging, styling and marketing reasons.

As the interior quality of competitors continues to increase, so the XK will respond with the highest-quality cabin ever seen in a Jaguar sports car. The design inspiration comes from the new XJ, with that car’s clever blend of hand-stitched leather and hi-tech materials taken to a new level. Expect the TFT-screen instrument panel technology developed for the XJ to be employed in the XK, along with the XJ’s electrical harness and system.

Under the skin the new XK is less ambitious, featuring a carried-over rivet-bonded platform of alloy extrusions borrowed from today’s car; Autocar understands that this key decision has been firmed up in recent months. That will keep the XK’s 2+2 cabin and relatively compact dimensions intact.

Much of the new car’s undercarriage is expected to be carried over, such as the front and rear axles and adaptive suspension, albeit with tuning improvements. The same goes for the powertrains, which will major on V8 petrol engines — both supercharged and normally aspirated — alongside the V6 diesel.

*sigh* - Another gaping mouth design. I found the "spitfire wing" front classy, understated and very Jaguar. This is just.... crass. I know people on this forum were clamouring for the V6 diesel to make its way in to the XK, it's a shame they waited for BMW to show the way and exploit the market rather than being the first ones in. The engine itself sounds decent and I've always thought of the XK as being a Grand Tourer rather than an out and out sportscar - a powerful, very torquey and very refined diesel would suit the character.

Should have done a 2.0 turbo petrol.

[quote beachland2] Should have done a 2.0 turbo petrol.[/quote] While I agree that they should offer a smaller, blown, petrol powerplant they don't have one of those. A new engine costs a fortune. They already have the diesel in other models, just had to "tinker" with it! Maybe their 2.5V6 could have been looked at for turbocharging and efficiency gains? If they could have put a very lightweight 6 cylinder engine in they would hopefully have maximised the weight loss by being able to reduce the weight of brake and suspension units so the smaller unit had less weight to lug around.

Had a think about the smaller, blown engines available to Jaguar and have come up with the following (please correct me if wrong). Some would involve raiding a parts-bin Jaguar may no longer have access to! 2.5V6 from x-type and s-type - related to the duratec in the Mondeo. Have heard bad things about turbo charging them, mostly related to Noble products. In s-type was used in longitudinal layout, so should present no problem there, but in unblown form only ~200bhp, far too low. 2.5T from Volvo products - Inline 5, seems to have only been used in transverse applications, no idea if could be mounted longitudinally. In the Focus RS puts out 300bhp and over 300lbf of torque which would probably be desired output? Same as the original 4.2V8. 3.0T from Volvo/Ford - inline 6 cylinder engine, turbocharged. Produces about 280bhp and the same torque. Can be mounted longitudinally - probably would give the smoothness and power expected of a Jag XK. By the time you're at a 3 litre, 6 cylinder engine would the weight and efficiency gains be worth it?

I like

I like this too, although the grille is perhaps slightly too large, and the chrome plated volvo-esque air intakes look as cheap as they do on Volvos.

18 February 2010

Wow this looks fantastic Jaguar is really improving these days. Wonder if they will produce something like the small F type concept as a rival to the BMW Z4 etc.

Well done Jaguar.

We should not get to excited about the picture; it is a render produced by AutoCAR and it is all speculation. Jaguar has not officially released any images yet.

Good point. But it wouldn't stop some criticising the design.

It doesn't matter what Jaguar design, the same people have the same moan about whatever the car looks like. Perhaps it validates their own choice of car?

Something we should discuss further, perhaps?

18 February 2010

If it looks anything like the car in the picture it willbe a triumph. Gorgeous, and I can't rememebr the last time I said that about a Jaguar (Probably the E type). This is design is as good as the Astons that are currnetly available.

3.0 litre sport diesel will fit the bill nicely and allow Jaguar to compete on a more level footing with the German Marques.
