JAGUAR'S FIRST-EVER V8 ENGINE TO POWER NEW XK8 SPORTS CAR
MAHWAH, N.J., June 12 /PRNewswire/ -- Jaguar Cars today revealed details of its first-ever V8 engine, which will power the company's new XK8 coupe and convertible when they go on sale in October.
The 4.0-liter AJ-V8 is the latest in a line of thoroughbred Jaguar engine designs spanning six decades. It also represents a milestone in British automotive design Automotive design is the profession involved in the development of motor vehicles or more specifically road vehicles. This most commonly refers to automobiles but also refers to motorcycles, trucks, buses, coaches, and vans. , being only the fourth Jaguar series production engine in the company's history. Totally engineered at Jaguar's R&D center in Coventry, England, the new engine drew heavily on the company's expertise in road- and racing car-engine design.
The result is a compact, rigid, refined and lightweight powertrain that delivers effortless high performance. The new powertrain comprises a 290-bhp, 32-valve, quad-cam, all-aluminum V8 engine coupled with the first five-speed automatic transmission ever fitted in a Jaguar.
Commenting on the launch of the new powertrain, Nick Scheele Sir Nicholas Scheele, BA (Dunelm), Hon DBA Cov, Hon DUniv C.England, Hon DTech Lond, Hon LLD Liv, Hon DSc Warw, Hon DTech Lough, Hon DSc Cran, Hon RCM, Hon FIMechE, (born 1944 Essex) is the current Chancellor of the University of Warwick and formerly President and Chief Operating , Jaguar's chairman and chief executive said, "The introduction of a new Jaguar engine is a significant event in motoring history. The AJ-V8 remains faithful to the Jaguar tradition by employing advanced technology and design innovation to set new standards of power and refinement combined with world class quality. The new engine will make its market debut in Jaguar's exciting XK8 sports car in October."
AJ-V8 Extends the Jaguar Lineage
The first Jaguar engine, the XK twin-cam, straight six, was unveiled in the XK 120 sports car in 1948 and soon became a Le Mans-winning legend.
In 1971 Jaguar introduced the V12 engine
A V12 engine is a V engine with 12 cylinders in two banks. in the E-type (XK-E) and redefined the industry standards for power and refinement.
Jaguar's all-aluminum alloy six-cylinder AJ6 engine, which appeared in 1983, and its successor, the AJ16 in calendar 1994, employed high-efficiency, four-valve cylinder head technology for optimized performance and economy. The AJ16, praised by the automotive press for its refinement and performance, will continue to power Jaguar sedans in 1997.
Through the application of advanced technology, the AJ-V8 extends the Jaguar lineage to satisfy the demands of luxury car buyers worldwide, setting new standards in key design areas.
The advanced design of the AJ-V8 embodies an array of class-leading features:
-- It is the most efficient engine in its class with highest specific power (72.5 bhp/liter) and highest specific torque at low engine speeds.
-- A minimum 80 percent of peak torque is available between 1400 and 6400 rpm for quick acceleration across an unusually wide range of speeds.
-- It is the lightest engine in its class, at 441 pounds.
-- Variable inlet cam phasing (VCP VCP Verband Christlicher Pfadfinderinnen und Pfadfinder (German Scouts)

In four-stroke cycle engines and some two-stroke cycle engines, the valve timing is controlled by the camshaft. , increasing both low-speed torque and top-end power.
-- Liner-free cylinder bores enhance refinement and durability while reducing weight.
-- Plastic molded air inlet manifold Noun 1. inlet manifold - manifold that carries vaporized fuel from the carburetor to the inlet valves of the cylinders

-- The stiffest powertrain in its class delivers excellent refinement and durability.
-- The patented, precision split-block cooling system cooling system: see air conditioning; internal-combustion engine; refrigeration.

-- Thin-wall exhaust manifolds and close-coupled catalytic converters are capable of operating within 30 seconds of start-up to further reduce emissions.
-- Platinum-tipped spark plugs, "filled for life" transmission and maintenance-free drive systems reduce servicing costs. Service schedules in the U.S. and Canada require that for the first 100,000 miles (160,000 km) only the engine oil and filters need replacement.

New, Intelligent Five-Speed Automatic Transmission
The XK8 will be the first Jaguar to feature a five-speed automatic transmission. The electronically controlled ZF transmission features a wide gear ratio spread and an advanced low-inertia torque converter to match perfectly the engine's power and torque. The converter features a slip-controlled clutch to achieve a near-locked condition at low speed in high gears, enhancing fuel economy and refinement.
A 32-bit intelligent, electronic transmission control module determines exactly the right gearshift point based on driver demands and road conditions, enhancing vehicle performance and driveability. Yet when operated manually, the transmission will not pre-empt the driver's decision to keep the engine at or even above redline, an important feature for spirited driving especially in mountains. A rev limiter A Rev limiter is a device fitted to an internal combustion engine to restrict its maximum rotational speed. This is usually carried out to prevent damage to the engine, however sometimes these devices are fitted to prevent an engine reaching the point at which it develops maximum protects the engine during this kind of driving.
Also in keeping with the Jaguar tradition of building driver's cars, the "J-gate" transmission gate for the XK8 locks out overdrive when the driver shifts the gear lever from "drive" to fourth gear.
Electronic shift energy management reduces engine torque during gearshifts for seamless gear changes.
A New Powertrain Developed in 36 Months
The design and verification process for AJ-V8 delivered the all-new powertrain in just 36 months from program approval. Simultaneous engineering teams comprising engineers from Jaguar Powertrain and Manufacturing, together with representatives from key suppliers, were responsible for all aspects of powertrain design, manufacturing and quality from concept to production.

All-New, World-Class Jaguar Production Facility
The AJ-V8 engine is manufactured in an all-new, dedicated Jaguar facility located within the Ford Engine Plant in Bridgend, South Wales. The Jaguar "plant-within-a-plant" saved considerable investment costs by Jaguar. It is staffed by workers dedicated to Jaguar engine production and includes a linked flow-line of computer numerically controlled machines with automated loading and assembly. Component supply is on a "just-in-time" basis.
Final engine dress and installation into cars is undertaken at Jaguar's Browns Lane Plant Browns Lane in Coventry, England was the home of Jaguar Cars from 1951 until 2005. It was the historic site of all Jaguar production over this period, as well as the corporate headquarters and the Jaguar Daimler Heritage Trust collection of cars. in Coventry, England.
The AJ-V8 facility was planned and implemented by simultaneous engineering teams comprising manufacturing engineers from Jaguar and Ford (NYSE NYSE
See: New York Stock Exchange : F), working closely with machine tool vendors and Jaguar Powertrain Engineering. The AJ-V8 team blended Jaguar's experience of medium-volume, high-specification engines with Ford's expertise in high-volume production and implementation to create a world-class facility for Jaguar's new generation of engines.
