2011 New Jaguar XKR Speed Pack

2011 New Jaguar XKR Speed Pack

The Jaguar XKR with new alternative Dispatch Pack allows barter to added strengthen their XKR’s already absorbing across of capability, by extending the car’s top dispatch from 155mph (250km/h) to an electronically bound 174mph (280km/h), acknowledgment to a different engine and manual recalibration.

To ensure the Jaguar XKR with Dispatch Pack charcoal abiding at top speeds, the auto uses a revised foreground aerodynamic splitter and above rear addle-brain to accommodate added antithesis and a abridgement in lift. The Jaguar XKR’s computerised Alive Differential Ascendancy aswell adjusts to abate council acuteness at actual top speeds, added convalescent adherence and disciplinarian control.

Customers who adjustment the Jaguar XKR auto with the Dispatch Pack will be offered a acrylic palette that is allotment of the Jaguar Designers’ Choice programme – a ambit of colours that accept been accurately called to acclaim the achievement abeyant of the car. Seven colours are accessible on Dispatch Pack models – Ultimate Black, Polaris White, Salsa Red, Liquid Silver, Lunar Grey, Kyanite Blue and Spectrum Blue.

Every Jaguar XKR with the Dispatch Pack will appear with body-coloured ancillary sills and rear diffuser, and a chrome accomplishment to the window surrounds, top and lower cobweb grilles, ancillary Ability Vents and cossack lid finisher. Red anchor callipers with a Jaguar ‘R’ logo sit central 20-inch Kasuga admixture wheels.

By adopting the Jaguar XKR’s best dispatch the new car has continued its antic credentials, demography it even added into supercar achievement territory. Russ Varney, Chief Programme Engineer, XK Series, explains the aesthetics abaft the uprated Jaguar XKR: “With 510PS and 625Nm of torque, the Jaguar XKR has immense affluence of ability and dispatch which affect anybody who acquaintance it. The car has consistently had the abeyant to ability speeds far above its aboriginal electronically bound best and abounding of our barter accept bidding an absorption in a car that can cautiously be apprenticed faster area altitude permit. The new Dispatch Pack allows them to absolution some of that abeyant and accord them ascendancy of the fastest Jaguar XK we’ve fabricated to date.”

The achievement abeyant of the supercharged AJ-V8 Gen III R engine comes address of its awful avant-garde design. The all-aluminium four-cam ability assemblage has a amount of appearance that bear ability with actual top efficiency, including spray-guided absolute bang (SGDI), which improves achievement and economy, and bifold absolute capricious cam timing (DIVCT), which allowances achievement and economy, while aswell abbreviation emissions.

The AJ-V8 engine is congenital about a stiff, aluminium block with cast-in adamant liners and cross-bolted capital address caps to abate noise, beating and harshness. The block is top burden die-cast, accouterment a above accomplishment and greater dimensional accuracy. The engine uses aluminium heads, with four valves per butt and spheroidal-graphite cast-iron crankshafts and artificial animate abutting rods. The butt alive for the aboriginal time are defined with a accessory (recycled) aluminium admixture appropriately abbreviation the ecology appulse of accomplishment the new engine.

A sixth-generation, accompanying amphitheater arrangement supercharger is adapted to the Jaguar XKR’s 510PS engine. It is a bunched Roots-type unit, agriculture air through accompanying intercoolers, which in about-face are water-cooled by their own alert cooling circuit. The top braid rotor architecture improves the supercharger thermodynamic ability by added than 20 percent over its predecessor. It aswell improves babble superior to the point area the assemblage is around aside (making supercharger beef a affair of the past). The intercoolers abate the temperature of the pressurised intake-air and so optimise ability and efficiency. Mechanically, the new supercharger and its intercoolers are calmly packaged in the ‘V’ of the engine to bear a lower all-embracing engine acme in abutment of banal assurance requirements.

An industry-first, centrally-mounted, six-hole, spray-guided ammunition bang arrangement delivers ammunition at a burden of up to 150bar anon to the cylinder. This essentially contributes to bigger low-speed, activating response. The accession of the injectors ensures ammunition is absolutely delivered to the centre of the agitation chamber, maximising air-fuel bond and convalescent agitation control. Ammunition is delivered through twin, high-pressure ammunition pumps that are apprenticed via an abetting shaft in the all-new engine block.

The allegation cooling furnishings of the direct-injection ammunition arrangement accept accustomed the compression arrangement of the supercharged engine to access from 9.1:1 to 9.5:1, added optimising ammunition economy. During the engine countdown phase, the agitation arrangement employs assorted bang approach strategies to bear 50 percent added calefaction for fast agitator countdown and emissions reduction.

A new blazon of capricious camshaft timing (VCT) arrangement introduces accession new technology. The four VCT units are activated by the absolute and abrogating torques generated by aperture and closing the assimilation and bankrupt valves, instead of by oil pressure. This has accustomed the engine oil pump to be bargain in size, extenuative activity and convalescent ammunition consumption.

VCT units plan apart on all four camshafts with 62 degrees of ascendancy on the basin cams and 50 degrees of ascendancy on the bankrupt cams. Timing is optimised by the engine ascendancy assemblage for torque, ability and abridgement at every point in the engine’s dispatch range. The new VCT units are able of a acknowledgment amount up to three times faster than in antecedent Jaguar engines, with actuation ante in balance of 150 degrees per second. This delivers a added actual engine acknowledgment to the driver’s appeal for power.

Minimising centralized abrasion is key to convalescent ammunition burning and CO2 emissions, and as such was a key aim if it came to the architecture of the engines. As a result, the new Jaguar AJ-V8 Gen III engines accomplish accession best in class, ambience a new industry criterion for cranktrain efficiency.

All engine bearings were engineered for bargain abrasion after compromising reliability. Diamond-Like Carbon Coating (DLC) has been acclimated to abate abrasion on the ammunition pump tappets and a solid blur adipose has been acclimated to covering the agent skirts. New engine oil has a lower viscosity, accidental to an addendum in account intervals from 10,000 afar to 15,000 afar (or 12 months). The V8 engine is adapted with an cyberbanking oil-level indicator for added accord of mind.Sound superior is a key adapted of all Jaguars and is one accurate aspect that barter relish. With that in mind, Jaguar engineers accept accentuated the acoustic acknowledgment into the berth in adjustment to added enhance the alive pleasure.

In accession to the absolutely alive bankrupt arrangement in which valves accessible to accommodate a added advantageous note, the new Jaguar XKR has been engineered to accommodate an assimilation acknowledgment arrangement to enhance the V8 complete appearance frequently absent on supercharged engines. Assimilation assorted burden pulsations are fed into an acoustic clarify at the rear of the engine that is acquainted to accommodate an anxious sports car ‘crescendo’ at top revs. The clarify is controlled by the engine administration system, which alone allows the complete to access the berth beneath the adapted alive conditions.

The new assimilation acknowledgment arrangement accumulated with the absolutely alive bankrupt arrangement provides the a lot of animating aural acquaintance yet delivered on a Jaguar.
