get more purr and snarl

Herald Sun - Motoring - - Front Page -

Zero to 100km/h in the nat­u­rally-as­pi­rated V8 is achieved in 5.7 sec­onds. The XKR does the same sprint in 4.9 sec­onds. The big sur­prise is the tur­bod­iesel, which hits 100km/h in a re­spectable 6.4 sec­onds.

In keep­ing with the XFR’s ex­tra grunt, Jaguar has spec­i­fied a new ac­tive dif­fer­en­tial con­trol sys­tem and adap­tive dy­nam­ics, an­other term for com­puter-con­trolled sus­pen­sion, as well as a faster steer­ing ra­tio and larger brakes.

The ac­tive dif­fer­en­tial is es­sen­tially a so­phis­ti­cated elec­tronic lim­ited-slip dif­fer­en­tial. When not needed the sys­tem is switched off so, un­like a me­chan­i­cal ver­sion, there is no risk of un­de­sir­able un­der­steer at low speeds.

An­other fea­ture of the Jag ac­tive diff is that it cre­ates no noise, vi­bra­tion or harsh­ness prob­lems at low speeds.

The XKR’s adap­tive sus­pen­sion mon­i­tors and ad­justs damp­ing to suit road con­di­tions in a sim­i­lar way to the CATS sys­tems on pre­vi­ous Jaguars.

The new sys­tem is con­fig­ured to rapidly as­sess body mo­tion and steer­ing wheel in­put to mod­u­late the damp­ing forces and re­duce roll and pitch.

Vis­ually the XFR gets a tricked-up ex­te­rior pack­age to prove to neigh­bours you’ve got the top-of-the-range ver­sion.

It has re­vised bumpers, lower front air in­takes, dis­creet body kit, bon­net lou­vres and grilles, quad ex­hausts and a small bootlid spoiler.

The other XFs get a choice of new al­loys and cos­metic in­te­rior up­dates.

Jaguar also has given the range stiffer bodies, stiffer rear sub-frames, stronger dif­fer­en­tials, up­graded brakes, an im­proved nav­i­ga­tion sys­tem, an acous­tic lam­i­nated wind­screen and an up­graded ZF six-speed au­to­matic.

As ex­pected of this level of lux­ury, all mod­els get a com­pre­hen­sive list of safety gear, leather and co­coon­ing cabins.

The safety gear con­sists of six airbags, an­ti­skid brakes, trac­tion con­trol, dy­namic sta­bil­ity con­trol and the im­mensely strong body.

This is sup­ple­mented by cruise con­trol, LED tail­lights, leather trim, rain-sens­ing wipers, rear park­ing sen­sors, au­to­matic cli­mate con­trol and 7-inch colour touch-screen. THE en­gi­neer­ing of the XF is proven and typ­i­cally Jaguar. There’s an all-en­com­pass­ing ride and a level of qual­ity that be­fits the brand. In fact, the qual­ity and equip­ment are help­ing to lift Jaguar’s rep­u­ta­tion to new lev­els.

With the new V6 tur­bod­iesel and nat­u­rallyaspi­rated V8s, the XF en­ters a new league.

The diesel is show­ing torque out­put that was once the pre­serve of high-per­for­mance V8 petrol en­gines and the su­per­charged XFR will keep the Ger­mans hon­est.

With 600Nm, the diesel is only 25Nm shy of the su­per­charged petrol V8, yet de­liv­ers its peak torque lower in the rev range.

Ac­cord­ing to Jaguar, the diesel’s pri­mary turbo has 61 per cent more torque at 1500 revs than the 2.7 while the secondary turbo has 32 per cent more power at 4000 revs.

What does this mean for driv­ers? Well, don’t dis­miss the S badge on the XF’s boot. It will launch it­self from stand­still without the hefty shove of the XKR, but with a very firm seat-of-the-pants push that de­liv­ers loads of torque way be­yond the point where most diesels are gasp­ing for breath.

The diesel shows the right stuff at over­tak­ing speeds. From 80km/h it pro­vides the surge needed to stay out of harm’s way.

The S is re­fresh­ingly petrol-like too. At idle we had to open the door to con­firm that it was, in fact, a diesel.

There is lit­tle rat­tle at idle and it sounds like a ro­bust petrol V6.

In more than 300km of of­ten spir­ited driv­ing the S re­turned 8.3 litres/100km. And if the diesel is not your cup of tea, then there’s the su­per­charged 5.0-litre V8 in the XFR.

What can we say, ex­cept that this en­gine is truly a de­light. Ped­alled rea­son­ably quickly it re­turned 12.9 litres/100km, within a whisker of Jaguar’s own fig­ures.

What is amaz­ing is the ef­fort­less power de­liv­ery, the crisp, lin­ear steer­ing and sur­pris­ingly com­pli­ant, yet firm ride. Even with the 20-inch wheels and al­loys the XFR rides in­cred­i­bly well. In most sit­u­a­tions you hear the pat­ter of road bumps rather than feel them.

Look out Mercedes-Benz and BMW, there’s a new kid from Jaguar to tickle your AMG and M per­for­mance sedans.
