Jaguar XF versus BMW 5 Series - comparison

There is clear substance to Jaguar’s claim to have brought the XF right onto the pace for performance, fuel economy and all-important CO2 emissions. The most frugal four-cylinder diesel versions of the car undercut their rivals from Audi, BMW and Mercedes-Benz on CO2. And whereas the more powerful diesel versions of the XF used to be a country mile off the standard set by other six-cylinder models, this one is different. The 3.0d S matches our 530d M Sport precisely on paper for claimed fuel economy, CO2 and the 0-62mph sprint. These are things clear-thinking business types are likely to consider before getting anywhere near a showroom.

As is price, an area where the BMW has a huge advantage. More than £5000 separates the list prices of our cars. That difference may narrow a bit for plenty of customers when they consider that the Jaguar is slightly better equipped than the BMW, but residual values will do nothing to mitigate for the Jaguar via the improvement of monthly lease costs. Our sources at CAP expect both cars to retain 48% of their list price over three years and 30,000 miles.

In the metal, there is better news for Jaguar. Superior packaging has addressed one of the old XF’s major failings, because although the car used to be almost the longest saloon in its class, it also used to be about the least spacious.

The new one is at once shorter and more roomy, although it is still not a car likely to sell on its accommodation levels.

The 530d, although shorter still, is even bigger inside. The BMW’s cabin – less rich and enticing than the Jaguar’s, but still more solid-feeling – is wider and longer and offers a little more head room in both rows. The BMW’s seats are broader, more adjustable and more supportive. So the 5 Series is a better ‘big saloon’ in all respects, if big is what you want. And I’m not sure XF drivers do.

In the XF, the driver trades outright space for a sense of cradled closeness at the wheel. Although the cars’ driving positions are very similar, the Jaguar’s door console, centre tunnel and roof feel closer to your extremities. The back seats are now no embarrassment and roomy enough for two big adults, mainly thanks to a recess carved out of the roof panelling. But the BMW’s back seats are notably bigger still and its boot is both longer and deeper.

A new fuel injection system and new turbochargers conjure significant power and torque improvements from the Jaguar’s V6 diesel and will doubtless convince some that the six-pot XF is a closer rival for the 535d than the model we’ve pitched it against here. However, on the road, the 530d’s engine is easily a match for the XF’s.

On mechanical refinement and flexibility, it’s honours even. The Jaguar V6 is better isolated at idle and low revs but also marginally more crotchety and less free-revving than the BMW straight six at high revs. Although the Jaguar feels stronger at times because of its greater mid-range torque, the BMW’s engine and gearbox are more responsive, so there’s nothing between the cars in terms of real-world pace, either.

Overall – albeit by only a nose – the BMW’s powertrain shades the contest, despite giving up so much on peak power and torque. Expect a 535d, then, to feel like a hot rod in comparison with the XF – just as it does next to every rival bar, perhaps, Audi’s 3.0-litre BiTDi A6 and A7.

Does this make the 5 Series the default driver’s choice that it always used to be, at the richer end of the diesel executive saloon spectrum? Perhaps for some it will. But frankly, even if you have only a passing, matter-of-fact regard for dynamic sophistication and driver appeal, I think you’d recognise that one of these cars is outstanding to drive and the other one only very good.

The XF has the 5 Series totally beaten for ride and handling. It’s more supple, compliant and quiet riding, both on the motorway and at B-road speeds, more progressively and deftly controlled in its vertical and lateral body movements, more agile and responsive through corners and much more tactile and communicative through its steering wheel. That the Jaguar comes with adaptive damping as standard and the BMW doesn’t (our test car did without it) helps to explain how such a striking advantage should be conjured for the XF on breadth of dynamic ability. But it can’t excuse it.

Whereas the 530d’s steering feels dull and heavy, the XF’s is incisive and bright. The pace and heft of the BMW’s steering makes it a car you have to muscle into corners, whereas the Jaguar feels more delicate, lithe and precise on its way to an apex. The XF’s steering also loads up beautifully as cornering forces build and returns to centre with natural weight.

Handling balance is an asset for both cars, with abundant torque, excellent throttle response and skilfully set grip levels allowing you to involve the rear axle in the cornering conversation whenever you like. But the Jaguar’s better damping and more dexterous wheel control make for a more consistent grip level and allow you to adjust its line more minutely.

The XF feels like a natural athlete, suffusing even its everyday motorway gait with a flavour of its softly sprung, effortless brilliance, and it makes the 5 Series feel like a journeyman – a gifted amateur, perhaps – with a practised but not nearly so polished routine.

Which brings us neatly back to where we started. Although it has been through a huge technical change, the XF hasn’t really changed much at all. It clearly wasn’t meant to – and that’s welcome news. The previous version spent most of its life at the top of our mid-size executive class rankings, thanks to a blend of natural, communicative, involving handling and a suppleness of ride that always served it well on UK roads – and that, for keen drivers, ultimately made its relatively inefficient engines and second-rate cabin space worth tolerating.
