Intrepid and Concorde Benchmarking
68 total-vehicle and vehicle-system target areas were established to define the character of the cars and to delight the customer. Objectives were shaded to reflect the individual character of each vehicle (Dodge vs Chrysler, Concorde vs 300M vs LHS). 296 Product Excellence targets were also established to increase the focus on ergonomics and the refinement of controls, switches, instrumentation, and body hardware.
The program used benchmarking to assess and rank key aspects of competitive vehicles and to establish fit, finish and body surface quality objectives. From that assessment, the capabilities of each car line in these areas were established and ranked on the basis of customer expectations and resource availability. Benchmark vehicles having similar construction were assessed to determine their technical efficiency. For example, cars with longitudinal, front-wheel drive power trains were evaluated for engine mount and power train noise, vibration and harshness characteristics.
For Intrepid and Concorde, the following benchmark vehicles, which are different from the marketing target vehicles, were used to establish functional performance criteria:
- Toyota Camry
- Ford Taurus
- Chevrolet Lumina
- Honda Accord
- Nissan Maxima
- Infiniti Q45, J30, I30
- Mazda Millenia
- Lexus LS 400
- BMW 740i
- Oldsmobile LSS
- Buick Park Avenue
- 1993-97 Chrysler LH series
Accommodations
The 1998 Concorde interior is 2.5 inches (64 mm) longer aft of the front seat, making its rear seat as roomy as that of the 1997 Chrysler LHS. Both manual and power seat tracks have 8.7 inches (220 mm) of longitudinal adjustment.
Lowering Concorde and Intrepid 0.5 inch and moving the windshield header rearward 0.62 inch (16 mm) makes the appearance sleeker. To maintain head clearance, the front seating position is lowered 0.25 inch (7 mm) and both the seats and the pedals have been moved rearward 0.5 in. (13 mm). This also places the pedals in line with the wheel houses, while providing more left-foot room for a more comfortable driving position. Concorde and Intrepid trunks are both larger and have more useable space than in 1997. Slim center and rear pillars provide wide door openings, particularly in the rear, for easy entry and exit.
Power trains
Both new engines provide increased specific output-power and torque per unit of displacement-while maintaining or increasing acceleration. Both engines are structurally stiffer, stronger, and more refined than their predecessors to make them run smoother and quieter. Both have platinum-tipped spark plugs and coil-on-plug ignition systems to provide 100,000-mile scheduled tune-up intervals.
Chassis
Refinement of the steering system, suspension systems and tires enhance steering, handling and ride while substantially reducing noise, vibration, and harshness.
Fuel Economy
The 1998 Concorde and Intrepid provide better fuel economy than their predecessors, thanks to:
- More efficient engines
- Optimized vehicle structure and use of aluminum to cut weight
- Reduced parasitic losses from wind resistance, tires, and brake drag
Electrical/Electronic Systems
A "battery saver" system turns off exterior and interior courtesy lamps if accidentally left on, to prevent discharging the battery. A starter override system prevents starter operation when the engine is running. Enhanced power train electronic system capabilities help assure mobility.
Body Exterior and Systems
The body structure is substantially stiffer than previous models for enhanced interior quietness.
Larger, quad halogen bulb headlamps give Concorde and Intrepid significantly improved lighting performance.
Aerodynamic development of the body and related systems significantly improved windshield wiper and washer performance. Body-mounted windshield washer nozzles with six individual washer jets (three per side) provide full glass coverage. One-piece, die-cast window opening moldings provide world-class fit and finish.
Interior Features
The following interior features are new or improved:
- Front cup holders provide increased versatility (they flip out from a center console)
- All-new seats provide increased comfort and support
- A new windshield defrosting system clears the glass more quickly and more completely than the prior system
- New radios provide easily understandable features and controls
- Radio and HVAC controls have the same appearance and feel
- The driver's floor mat includes a tie-down hook to hold it in place
Ergonomics
- The column-mounted multi-function switch stalk is raised slightly and its graphics are rotated toward the driver to improve visibility through the steering wheel
- The floor console armrest is raised 1.2 inches (30 mm) and the leading edge is slightly forward of its former location, making it level with the door armrest
- The remote trunk release button is readily visible and accessible on the instrument panel
- Radio and HVAC controls are in the center of the instrument panel and placed closer to the driver than on prior models. A new radio mounting system allows radio and HVAC controls to be closer to each other for easier access
- Radio and ATC (automatic temperature control) operation and logic are refined. Button shape, nomenclature, freedom from hidden functions, and tactile feedback contribute to clear and intuitive operation
- The steering column tilt lever is curved upward for easier access. In the past, this lever was used only on international models, but was judged ergonomically superior to the straight lever previously used in North America
- Steering wheel spoke size and placement are designed to allow a variety of hand positions and assure visibility of cluster and switches
- The steering wheel rim is softer and more comfortable
- The horn switch is operated by pressing the flexible steering wheel pad
Safety And Security
- Next-generation front passenger air bags use odorless, smokeless inflator technology
- Next-generation driver air bags use a hybrid inflator to reduce particulates
- Interior trim provides head impact protection
- Dynamic side impact intrusion protection
- Available Remote Keyless Entry system and HomeLink universal transmitter use "rolling code" technology to enhance security
Noise, Vibration, and Harshness
Reduced engine noise, better suspension isolation, improved body structural stiffness and better insulation all contribute to the quietness of the Concorde and Intrepid. A rubber-isolated rear suspension cross member significantly reduces interior noise for rear seat passengers. Front suspension and power train mounting cradle isolation is significantly refined. Larger door weather strips and more accurate door fitting help minimize wind noise. Full-stamped doors provide a consistent sealing surface for the weather strips.
Aerodynamics
The combination of a rounded front end in plan view, lower fascia shaping, gently flowing windshield pillars with a "cubic-curve" cross section (a shape that resembles a graph of the equation y=x3), aero-tuned sill cladding to enhance air flow around the tires and a tapered rear end improve aerodynamics. Both designs contain subtle aerodynamic refinements in the cowl, outside mirrors, windshield pillars and windshield header that reduce wind noise and help control water flow over the body as well as reducing drag. Drag coefficient varies among the two bodies due to detail variations in design, averaging 10 percent lower than the prior bodies. Aerodynamics helped design the following features to provide water flow management and wind noise reduction:
- One-piece side window moldings have the least possible offset from the glass with sedan-type door construction and include full perimeter sealing to the door frame that minimizes wind noise
- Full-stamped doors and full side aperture body construction provide more stable and accurate sealing surfaces to reduce wind noise
- A cowl screen formed to deflect air above wipers reduces wind noise and eliminates washer fluid upward flow off parked wiper blades
- Water channels in the windshield side moldings keep the lower half of the side windows clear while limiting wind noise
- Outside mirrors are shaped for low wind noise
- Full door opening upper weather stripping stops roof water from entering open doors
The following new or improved features help ensure ample cooling air flow through a tight engine compartment populated by high-output aluminum engines and close-coupled catalytic converters:
- Cubic-curve surfaces surround the grille opening to maximize air flow through
- the grille
- Slots in the cowl screen, allowing air to flow over the engine mounts and exit at the rear
- lip of the hood
- A portion of the hood-to-cowl seal is removed to provide a cooling air flow path over electrical and electronic equipmen
- Louvers in the engine compartment side panels and enlarged openings for the drive shafts and tie rods allow air to exit through the wheel wells
- Vastly improved front air dam and fascia and a small under tray between the lower radiator cross member and the power train/suspension cradle forces air to exit aft
- of the engine, not recirculate through the cooling module
- Baffles between fascia and radiator support panel force incoming air through the cooling module
