OCT 98] JAGUAR PRESS RELEASE
The New S-Type At A GlancePROCESS
- S-TYPE was designed and developed through innovative process management including early
component sourcing, crossfunctional programme teams, advanced quality planning, rapid
prototyping and predictive/analytical techniques.
- Dynamic Programme Simulation provided a rigorous, computer-based analytical 'test bed'
to determine, in advance, the implications of management decisions on issues such as
resources, productivity and prototype scheduling - the first automotive application of
this technique.
- Dimensional Management, employing computer-based assembly variation modelling
techniques, was used to determine the optimum body design, before building any prototypes.
Over one million 'virtual' cars were built on the computer to establish optimal assembly
processes before the start of production.
- Intensive operator training programmes and the building of prototypes on the production
line helped ensure manufacturing readiness at launch
- More than 450 prototype and pre-production AJ-V6 engines were built and tested on
dynamometers and in vehicles.
- Simulated autobahn durability tests were conducted equivalent to 100,000 miles at an
average of over 100 mph.
- Body engineers undertook computer aided simulation and aluminium soft tooling techniques
to perfect panel radii, material flow and manufacturing of the two-pressing, highly styled
bonnet assembly.
- Extensive acoustic windtunnel testing ensured best-in-class 'windnoise' isolation.
BODY STRUCTURE
- 'Limousine'-style door design extends into the roof line for easier entry and exit
- One-piece body side, incorporating the rear wing and a one-piece front door opening
panel provides a highly stable structure ensuring highly consistent shut lines and door
seal location.
- A plastic moulded reinforcement member, highly complex in shape, provides a very stable
mounting for the style-critical headlamps and grille.
- Leading-edge hydroform technology, injecting oil into a tube of steel, was used to mould
the shape of the complex radiator crossmember
- High strength steel was used in critical areas of the body following extensive finite
element analysis, optimising the weight of the bodyshell.
- All doors have triple seals with welded locating channels for optimum refinement.
- Body apertures restricted to a total of 25 cm2 to minimise air leakage,
maximising perceived refinement.
- 85 per cent of body-in-white, including all vulnerable areas, are double-sided, zinc
coated steel
- Specially shaped plastic outer sills minimise risk of stone chips on bottoms of doors.

SAFETY / ENVIRONMENT
- Bodyshell exceeds all crash legislation worldwide, including the latest European side
impact and offset frontal impact tests.
- Computer analysis and modelling were used extensively by engineers together with a
comprehensive dynamic crash test programme.
- High strength steel used in critical areas such as front longitudinals, seat belt
anchorages and suspension mounting points.
- Doors have hot-stamped boron steel side intrusion beams, full height B/C post and A
pillar reinforcements and one-piece front and rear door hinge reinforcement panels, all in
high strength steel.
- 'Catcher' bracket assemblies retain rear doors in their frames in the event of side
impact.
- Front end structure dissipates crash energy efficiently via convoluted front rails and a
roll formed solid steel beam.
- Energy absorbing ribs, moulded into the upper A and B/C pillar trim panels, and a
headliner of energy absorbing foam reduce risk of head injury.
- Fuel system includes deformable, plastic fuel tank under the rear floor, away from
impact zones and an inertia fuel cut-off switch.
- Front seat-mounted, side airbags protect both head and ribcage.
- Twin frontal airbags and pyrotechnic seatbelt pretensioners; passenger bag is powered by
environmentally friendly mix of clean air and twelve per cent hydrogen, which is smokeless
and easier to recycle.
- All rear seating positions have three point belts with automatically locking retractors,
ensuring child seats are securely restrained.
- Leading-edge restraints control module can discriminate between crash events warranting
airbag deployment and those which don't.
- Internally stroked steering column which telescopes within its own length, combines with
stiff mounts to achieve very robust and repeatable crash 'stroke'.
- AJ-V6 and AJ-V8 engines meet toughest exhaust and evaporative emission standards in the
world. High compression ratios, fast warm-up precision cooling system, variable cam
phasing and twin close-coupled catalysts deliver low emissions and good fuel economy.
- A minimum of 80 per cent by weight of each S-TYPE is recyclable, while 84 per cent of
component packaging is durable and returnable.
MANUFACTURING
- Development of Jaguar's Castle Bromwich site is one of the largest UK inner city
investments for 50 years.
- At Castle Bromwich, S-TYPE bodies are constructed, painted and finally assembled into
complete cars (on the same site, the bodies for Jaguar XJ saloon and XK sports cars are
constructed, painted and shipped to Jaguar's Browns Lane plant in Coventry for final
assembly).
- The majority of components are delivered by suppliers to the trackside on a just-in-time
basis.
- 4500 spot welds on each S-TYPE body are applied by the latest computer controlled
machines, using closed-loop secondary current control for precision welding.
- Body panels may be audited by positioning in environmental cubes which
perform a thorough geometric check of all components.
- The one-piece body side pressings, incorporating the rear wing, nearly 4 metres long,
are formed in a 2,000 tonne capacity press.
- Door and bonnet outer panels are made from a special bake-hardening steel, more
resistant to minor impacts.
- Accurate fitting of doors, bonnet and bootlid ensured by precise measurement of body
openings, achieved by means of a laser camera system, which also performs a final check on
the overall geometry of the body.
- Paint shop is a sealed, clean room with controlled temperature and humidity. Among the
environmental measures are close control and incineration of remaining paint solvent
emissions.
- New environmentally efficient, gas-fired boiler house and effluent treatment facility
installed at Castle Bromwich for S-TYPE production.
- Waterborne paint system cuts basecoat solvent emissions by 85 per cent.
- The body is internally protected by hot wax injection, which flows into place during
stoving.
- Final assembly is performed on a series of skillets (platforms of laminated wood) to
create a continuously moving floor for efficient, ergonomic assembly.
- The drivetrain is built up in two separate assemblies:
(i) engine, transmission, front suspension, brakes and steering rear axle assembly -
(ii) final drive, rear drive shafts, rear suspension and brakes.
- With the addition of the propeller shaft the complete driveline assembly is dynamically
balanced in a special rig, rotating the propshaft at 250Orev/min.
- When mating the driveline to the body, laser cameras are used to validate alignment.
- Each completed car is the subject of a comprehensive electrical check by means of VCATS
(Vehicle Configuration and Test Systems).
- Non-contact laser technology measures front and rear suspension geometry and headlamp
alignment.
- Further validation is performed on a rolling road, including engine, transmission,
brakes.
- At the final inspection stage, each car passes through a high intensity water spray
line, equivalent of a monsoon, tilting the car to simulate 'awkward' parking situations.
All water test facilities feature a low loss recirculation system.
