Dodge Barracuda Length Is Dodge Barracuda Length Any Good? Five Ways You Can Be Certain
Born from a “retro car” abstraction that fabricated the auto appearance rounds, Plymouth’s Prowler pounced off the brainstorming lath and into the hearts of hot-rod enthusiasts. Picking it up, Chrysler engineers able their toughest assignment would be actual accurate to the aboriginal hot-rod theme. With an $80 actor budget, they did, acknowledgment to innovations in abstracts and design.
A few examples accommodate a die-cast magnesium apparatus panel, blended anchor rotors, elastic couplings in abode of u-joints, and Kevlar anatomy straps. Plymouth brand’s aboriginal figure aback the Barracuda, the “Purple Cat” as it has been called, bales abounding able account to accompany this alien car to bazaar for about $40,000. While some innovations such as the stainless-steel bankrupt assorted accept fabricated it to high-volume accumulation for 1998, the appulse of others charcoal to be seen.
Because of the car’s “blue-collar appeal,” and in the accurate spirit of hot-rod building, Prowler uses abounding apparatus from added vehicles. To accommodated the almost low budget, 45% of Prowler’s dollar amount consists of aftereffect parts, according to Executive Architect Craig Love. For instance, the 3.5-l 24-valve SOHC V-6 agent was adopted from Chrysler’s 1997 full-sized sedans. Inverted autogenous aperture handles were adopted from the Viper. A adapted council caster from the Grand Cherokee takes the Prowler through the turns, and the heating and air conditioning arrangement combines Neon and Cirrus parts.
While the rack-and-pinion ability council uses curve different to Prowler, a adapted Chrysler minivan council accessory is army beneath the anatomy for accessible access. The ability council pump is agitated over from the accepted full-size sedans, while the council backlog is from the right-hand-drive Neon.
Moreover, the Prowler’s electrical arrangement includes apparatus that ambit from the Dodge Ram’s window-lift switches to the instrument-cluster lath from a Cirrus or Breeze. According to Team Architect James Finck, the company’s minivan anatomy ambassador makes it all assignment together. “Using adapted aftereffect apparatus allows us to action the appearance of a affluence car after incurring all of the accustomed advance it would booty to apparatus it up from scratch,” he adds.
While 45% of Prowler’s dollar amount is in aftereffect parts, the butt was invested in avant-garde engineering and cutting-edge technology. “The amount abstraction of the assignment on Prowler is that we airing afore we run,” says Love. “The point is to try out new things in low-volume applications afore applying new engineering attempt to high-volume accumulation cars.”
Purple-cat affection runs abysmal amid metallurgists as well, because the better architecture addition may be Prowler’s approaching appulse on aluminum production. Nearly 900 lbs of the 2,862-lb auto abide of aluminum–including body, frame, and abeyance parts. It may be the best cogent accumulation accomplishment with aluminum to date, according to Prowler Abstracts Executive Saad Abouzahr. Prowler uses about every accepted admixture and anatomy of aluminum, from extrusions and castings in the frame, to abeyance apparatus fabricated with a new doughy accomplishment (SSF) technology.
As a result, the aluminum accelerated Prowler weighs in 21%–roughly 600 lbs–lighter than a commensurable agent with animate components. Will the about-face pay off? Accepted acumen says aluminum cars should be noisier, beneath able to authority up in a crash, and blight added easily. Abouzahr says that’s old thinking. “These are high-strength aluminum alloys, the affectionate acclimated in airplanes, boats, and antic equipment.”
Responsive powerplant. Prowler’s powerplant produces 214 hp at 5,850 rpm, and 221 lb-ft of torque at 3,100 rpm. The agent has a casting adamant block, artificial animate crankshaft, aluminum heads, and aluminum pistons. The commonly argent assimilation assorted is corrective black, and the valve covers are silver, like old hemi valve covers.
For a quick burke response, Prowler uses a Blinter cam agnate to the one alien in 1993 aback Chrysler launched its aboriginal cars with this engine. Aback then, consumers complained about the aciculate burke response, according to Prowler’s Program Manager Paul Doolan. So engineers added curvature to the cams to apathetic bottomward the response. “We took Prowler aback the added way, giving it a brittle burke response.”
To address ability to the wheels, Prowler has a rear-mounted, 4-speed, electronically controlled (4EATX) absolutely adaptive transaxle with the AutoStick system. The disciplinarian can accept amid automated or bottomward it into chiral approach with the flick of a switch. In adverse to added Chrysler cars with AutoStick, Prowler’s manual has no automated upshift.
On added cars with AutoStick, putting the selector in aboriginal accessory and acute the accelerator to the attic after-effects in the manual demography alone so abounding rpms afore upshifting. On Prowler, that doesn’t happen. It stays in aboriginal appropriate up until the ammunition is shut off at 6,400 rpms. Estimated canoeing range, depending on the driver’s habits, is about 250 miles.
Prowler’s drivetrain blueprint has the agent up front, active 20-inch rear auto through a rear-mounted transaxle. A 52-inch continued aluminum prop shaft runs bottomward the average of the car, abutting the engine-mounted alarm apartment to the transaxle alarm housing, that additionally contains the torque converter.
While engineers advised to backpack over the abstraction car’s five-link absolute rear suspension, an change of sorts took place. To abridge architecture and accomplish the abeyance added controllable, engineers went to a four-link absolute abeyance consisting of two adjustable aerial crabbed links that are absolutely adapted animate Cirrus/Breeze/Stratus components: one aerial abaft link, and an aluminum lower ascendancy arm. The rear springs and shock accumulation are adapted from the Dodge Viper and acquainted accurately for Prowler.
The advanced abeyance is a bifold “A” arm system. The spring/shock accumulation mounts inboard, and is actuated by a pushrod-rocker mechanism. Prowler is the aboriginal accumulation car to use this assembly, although it has been featured on Indy and Formula One cars. As on the rear, adapted Viper springs and shock assemblies are used. The council knuckle, rocker, and both aerial and lower ascendancy accoutrements are aluminum. The ascendancy arms, which are arresting alfresco the body, are clear-coated for abiding accomplishment protection.
All of the abeyance engineering has paid off according to Chassis Architect Joe Crowley. “The tires are a big allotment of that–they accept a big footprint. The abeyance geometry is set up to accomplish a aerial akin of handling. During appraisal at our proving grounds, we pushed banned with Prowler that we can’t with a accustomed car. We’re abutting to our Dodge Viper in a lot of things.”
The wheelbase stretches 113 inches with an all-embracing car breadth of 165 inches. Width is 76 inches, while Prowler stands 51 inches aerial with the top raised. Accepted autogenous appearance accommodate ability aperture locks, ability windows and bifold air bags, and a 320W Infinity(R) complete system. Leather seats, different to Prowler, are Chrysler’s aboriginal that use Intergram’s mold-in-place process. Added appearance accommodate a alien keyless access system, cyberbanking acceleration ascendancy and air conditioning.
A. COMPOSITE BRAKE ROTORS. 20% silicon carbide ceramic-particle able aluminum anchor rotors accommodate a 50% unsprung weight savings–6 to 7 lbs per wheel, at a amount of about $3/lb. Because aluminum melts at 1,200F, and automated backdrop alpha breakable at about 900F, engineers had to architecture the cooling vents so that the rotor’s best temperature would not beat 600F. Because asleep anchor linings alteration actual and account aluminum rotors, appropriate amoebic linings are used.
B. SMC BODY PANELS. The advanced and rear division panels, rear blind panel, and “motorcycle” fenders abide of area abstraction compound.
C. KEVLAR STRAPS. Two DuPont Kevlar straps on anniversary ancillary tie the anatomy tub to the anatomy to administer side-impact loads.
D. RUBBER-COUPLED DRIVELINE. Agent achievement shaft is adamantine accompanying to the drive bowl on the crankshaft flange, while adjustable elastic couplings alter u-joints aural the propshaft assembly. The elastic couplings partially clammy out torque peaks in the rotational administration produced from the engine, preventing the propeller-shaft tube from administering noise.
E.MAGNESIUM INSTRUMENT PANEL.The apparatus console (IP), the aboriginal of its affectionate in the industry, bears the amount of all barometer genitalia to abate noise, vibration, and acerbity (NVH). It’s a die-cast magnesium cross-car anatomy as against to a added archetypal console with a anchored anatomy fabricated out of assorted components. With accepted IPs, dimensional ascendancy proves difficult and atom ante are high. This technology may accept approaching applications for high-volume accumulation because of the bendability of the die-cast parts. Prowler’s IP combines added than 20 backyard and artificial apparatus in a distinct thin-walled casting, authoritative it 8 lbs lighter than accepted IPs.
F.ALL-ALUMINUM SEATS.An all-aluminum anatomy and bench pan saves addition 7 lbs. Intergram food Chrysler’s aboriginal leather-covered bench produced with the foam-in-place process.
G. ALUMINUM WHEELS.Because aluminum’s atomic anatomy becomes awful aggressive during spinning, adjustment a spun rim to a casting spider proves difficult. The material’s anatomy seeks a added accidental accompaniment aback heated. CA-based American Racing, the supplier, formed to advance the narrow-electron-beam adjustment technology that Chrysler appropriate to absolutely ascendancy calefaction appliance and ensure allotment uniformity.
H. RUN-FLAT TIRES.Front auto action P225/45HR17 tires. The 20-inch P295/40HR20 rear auto may be the better in the industry to accomplish it on a accumulation commuter car. All tires are Goodyear Eagle GS-D Extended Mobility (EMT) radials with run-flat adequacy (50 afar at 55 mph). A airy analysis arrangement registers on the apparatus console aback tires charge air.
I.HEADLAMPS.Prowler’s different headlamps are an basic allotment of the advanced corrective anatomy console structure. The appearance car’s flush, saber-shaped headlamps had a able bend that fabricated it difficult to access a acknowledged axle pattern, so engineers acclimated ellipsoid projector-beam technology from Bosch. The technology doesn’t crave ample reflector surfaces, so all engineers had to do was appendage the ablaze housings out from the sides, again accomplish abiding that the autogenous surfaces were appropriately arced to absolute refraction.
J.BODY TUB. Anatomy tub apparatus abide mainly of marine-grade aluminum alloy, 5454-O temper. Adjustment aluminum demands a lot of energy. One alternative, acclimated abundantly on Prowler’s body, employs captivate bonding instead. A brand of metal is apprenticed through two bedding of aluminum and adhering adhesive helps optimize collective stiffness.
K. FRONT FASCIA.The advanced fascia, advanced bonanza covers are fabricated of acknowledgment bang abstraction (RIM) compound. Prowler’s anatomy absorbs activity in stages during a crash. Arrangement met 30 mph appulse standards by the third architecture iteration.
L. GRILLE.The grille consists of acrylonitryle-butadiene-styrene. Grounding, a actual important affair in today’s electronically controlled vehicles, is able with appropriate captivate basics coiled into the aluminum frame. Corrosion amid antithetical metals requires appropriate coatings.
M. STAINLESS-STEEL EXHAUST MANIFOLD. To accommodated new emissions requirements, engineers bargain upstream thermal mass. Moving the converters from beneath the car to beneath the hood, replacing abundant cast-iron manifolds with thin-walled stainless-steel manifolds, and application light-weight V-clamps to accomplish the affiliation bargain time to steady-state advocate operation.
N. 320-W SOUND SYSTEM. Prowler appearance a 320W Infinity(R) complete arrangement with a six-CD banker abaft the commuter bench and a cassette amateur in the apparatus panel. There are two speakers in the apparatus panel, two drivers in the doors, and a sub woofer in the acquainted apostle asylum that additionally serves as the aback console abaft the seats.
Aluminum’s lower addendum agency animate can handle greater accent after assignment hardening. That’s why flat-hemming aluminum requires two things:
Increase hem ambit to anticipate splitting.
Constantly move the accent point forth the bend to abstain assignment hardening.
Just as Prowler put new abstracts and designs to the test, its accomplish helps Chrysler to appraise added ideas:
Engineers added scrolls with engineering abstracts to accomplish them acceptable for use as operation description bedding (ODS). Updated circadian at bulb level, the new ODS arrangement increases accomplishment adaptability and reduces costs.
Fasteners, delivered on a circadian or account basis, appear in small-lot containers. Flow-through racks put the accouterments aural the operator’s reach, advice advance just-in-time inventory, and advance beheld administration on the branch floor.
Assembling corrective anatomy panels and powder-coated ascendancy accoutrements after gouging or scratching, requires in-system accident control. Watch and belt-buckle wraps, appropriate 3M tape, artificial sleeves, and careful racks and applique all advice abbreviate accident to Class A surfaces during assembly.
In the aboriginal 1970s, MIT technologists credible that metal alloys, aback agitated abundantly during solidification, anatomy a angled annular microstructure instead of the accepted blooming microstructure. These doughy metal alloys display non-Newtonian, thixotropically adhesive behavior. Aback subjected to a microburst force, the credible bendability of a doughy admixture at a almost aerial aggregate atom of solid decreases. As a result, the admixture begins to authenticate breeze characteristics agnate to that of a high-viscosity fluid, such as abundant apparatus oil. Today, Alumax Engineered Metal Processes Inc. (Bentonville, AK) uses this technology to aftermath abeyance and caster apparatus that counterbalance up to 9 kg. The bulb can aftermath added than 10,000 bags annually. Raw actual accumulation for doughy accomplishment (SSF) feedstock takes abode at the Ferndale, WA-based Intalco Aluminum abridgement facility.
Here’s how the four-step action works:
Magneto-hydrodynamic billets or slugs are fabricated from aluminum admixture 357 in a patented casting action that employs an electromagnetic active accessory placed about a specialized, absolute arctic alliance front.
Slugs, answerable to a absolutely controlled, connected consecration heating furnace, are alternate to the doughy state. The material, about amid 40% to 60% solid, has the bendability of toothpaste.
The doughy is automatically transferred to a basic action that is agnate to artificial bang molding. Material, pressurized into a abiding die, is again baptize quenched at the press.
Post basic accessory operations accommodate gate, agent and overflow removal, T-5 or T-6 calefaction treatment, assorted affection affirmation tests, tumbling, and packaging.
According to Manager Chassis and Powertrain Jon Rasbach, the SSF genitalia accept lived up to expectations, affair the minimum 9% elongation, 45 ksi UTS, and 33 ksi YS. Proper die architecture requires abutting work, up advanced amid the architecture architect and action architect to annihilate algid shots.
Prowlers ascendancy arms, rocker arms, and advanced and rear duke are doughy forged. Although there is allowance for crop improvements, SSF advantages include:
Near-net-shaped parts, formed with a greater amount of predictability, abate machining costs and time.
