Dodge Viper SRT10® ACR (American Club Racer)

 

Le Nordschleife du célèbre circuit du Nürburgring dans l’Eifel, semble être devenu le « place to be» et « to be seen » La plupart de constructeurs « s’y donnent rendez vous » afin de prouver par le verdict relativement impartial du chrono que leur auto est la meilleure – lisez la plus rapide sur ce circuit mythique qui exige énormément de talents, tant des hommes que de leurs machines.

Le dernier en date à s’y être présenté est Chrysler, lequel, pour l’occasion , avait amené dans ses valises (qu’il faut reconnaître très grandes) la Dodge Viper SRT10® ACR (American Club Racer).

Les 7’ 22’’ 1/10 réalisés par l’engin, ne correspondent qu’au record de la catégorie des voitures de production homologuées pour usage routier.

Patience donc, amis de la vitesse, de l’évolution de la vitesse et de la statistique. Ce chiffre ne sera pas le dernier. Quant à savoir à quel moment il passera à la trappe ?


 

Dodge Viper SRT10® ACR (American Club Racer) 2008.

 

Dodge a établi un nouveau record de la piste sur le mondialement célèbre circuit du Nürburgring en Allemagne.

La Dodge Viper SRT10® ACR (American Club Racer) 2009, a en effet battu le record dans la catégorie des voitures de production homologuées pour un usage routier avec un chrono, attesté, de 7 minutes et 22,1 secondes.

Long de 20,8 kilomètres et appelé familièrement ‘le Ring’ par les passionnés, le circuit du Nürburgring accueille régulièrement des compétitions et se situe à Nürburg en Allemagne. Construit dans les années 1920, le circuit du Nürburgring est toujours utilisé et est considéré comme l’une des pistes les plus difficiles, les plus dangereuses et les plus exigeantes au monde. N’ayant jamais procédé auparavant à des essais sur la piste du Nürburgring, les ingénieurs de SRT avaient loué la piste durant quatre heures. Après cinq tours seulement, la Dodge Viper ACR établissait un nouveau record du tracé.

Dernière venue dans la famille SRT (Street and Racing Technology) de véhicules hautes performances de Chrysler LLC, la Dodge Viper SRT10 ACR 2009 développe une puissance de 600 chevaux et bénéficie d’une homologation routière tout en étant développée pour être en mesure d’affronter les pistes de compétition. Grâce à cette homologation routière, les fanatiques de Viper peuvent conduire leur monture jusqu’au circuit, la piloter sur la piste à un rythme extraordinaire et ensuite retourner à son volant jusque chez eux. Par rapport à la Dodge Viper, un modèle déjà très performant, la Dodge Viper ACR bénéficie de suspensions réglables, de roues allégées, de doubles disques de freins, de pneus de compétition homologués pour la route et d’appendices aérodynamiques qui lui permettent de bénéficier d’un appui de 450 kg à une vitesse de 240 km/h.

Pour piloter cette Dodge Viper ACR sur le Nürburgring, SRT avait fait appel à Tom Coronel, un pilote chevronné qui était au volant d’une Dodge Viper GTSR à l’occasion des deux dernières éditions des 24 Heures du Nürburgring. Tom pilotait pour la première fois la Viper ACR à l’occasion de ces essais.

Le précédent record, certifié, pour un modèle de production homologué sur la piste du Nürburgring était de 7 minutes et 34 secondes.

 

Le 18 août, la Dodge Viper ACR a pulvérisé ce record de près de 12 secondes.

Dodge Introduces Street-legal 2008 Viper SRT10® ACR
 

• Dodge delivers ultimate purpose-built, street-legal track car

 

• 2008 Dodge Viper SRT10® ACR offers reduced weight, race-ready hardware and competition tuning for optimal on-track performance

 

 

Auburn Hills, Mich. November 9, 2007– Dodge announced today that the all-new 2008 Dodge Viper SRT10® ACR — short for American Club Racer — will make its public debut at next week’s Los Angeles Auto Show.
 

The latest addition to Chrysler LLC’s Street and Racing Technology (SRT) family of performance vehicles, the all-new, 600 horsepower 2008 Dodge Viper SRT10 ACR is a street-legal Viper engineered to dominate on the race track. Because it is street legal, die-hard Viper and track enthusiasts can drive their car to the race track, run it at top speed on the track and then drive it home.
 

"With the all-new 2008 Dodge Viper SRT10 ACR, SRT has taken the ultimate American sports car and injected it with an extra dose of racing DNA," said Mike Accavitti, Director – Dodge Brand and SRT Global Marketing and Communications, Chrysler LLC. "With the Viper SRT10 as the starting point, SRT engineered a combination of reduced weight, race-tuned suspension and aerodynamic improvements to create the ultimate Viper for the street and track."
 

Derived from the all-new 2008 Dodge Viper SRT10, the heart and soul of the all-new 2008 Viper SRT10 ACR is SRT’s new 8.4-liter aluminum V-10 engine that produces 600 horsepower and 560 lb.-ft. of torque.
 

The 2008 Dodge Viper SRT10 ACR stays true to the five key aspects of SRT: standout powertrain, bold exterior styling, race-inspired interior, benchmark braking and world-class ride and handling characteristics across a dynamic range.

 

Bold Exterior Styling
 

The 2008 Dodge Viper SRT10 ACR exterior styling cues offer not only bold aesthetics, but functional benefits on the track. These include a variable geometry "fanged" front splitter, an adjustable rear wing sculpted by CFD (Computational Fluid Dynamics) and optimized front dive planes. These new aerodynamic devices are formed in high-performance autoclaved carbon-fiber. By using both unidirectional and woven laminates, the aero equipment is optimized for the minimum weight possible.

The splitter and dive planes feature a clear-coated carbon-fiber weave on all Viper SRT10 ACR models.
 

The front splitter includes three removable rub strips that provide protection and wear resistance. Supported by stainless steel tension cables, the splitter is designed to absorb the energy from minor upward deflections.
 

The Dodge Viper SRT10 ACR aerodynamics are tuned and balanced to maximize downforce and provide increased levels of lateral grip. Each Viper SRT10 ACR also includes a track extension that replaces the center splitter rub strip and fills out the fanged splitter scallop for closed-circuit events. The aerodynamic effect of the track extension is a reduction in overall drag and an increase in front downforce of nearly one-third.
 

The front fog lamps have been deleted and replaced with lightweight filler panels.
 

The 2008 Viper SRT10 ACR features a signature two-tone paint scheme with a black center section. An optional driver’s stripe is available on a two-tone Viper Red or a Viper Black ACR. The driver’s stripe also features a sewn leather accent on the steering wheel. A clear-coated exposed weave is featured on the rear carbon-fiber wing of all two-tone and driver’s stripe Viper SRT10 ACR models.
 

A standard Viper SRT10 monotone paint scheme is also available featuring a body-color rear wing and dual painted Viper stripes.
 

The 2008 Dodge Viper SRT10 ACR is available in five colors: Viper Red, Viper Black, Viper Violet, Viper Bright Blue Metallic and Viper Very Orange.
 

Lightweight forged aluminum Sidewinder wheels are painted gloss black to complete the one-of-a-kind exterior styling.

Race-inspired Interior
 

Based on the 2008 Dodge Viper SRT10 interior, the Viper SRT10 ACR goes a step further to satisfy what racers want: the least weight possible. An optional "Hard Core" package offers maximum weight savings by deleting the audio system, underhood silencer pad, trunk carpet and tire inflator. The radio is replaced by a lightweight cover that can be configured to mount the included lap timer. The door speakers are replaced by lightweight carbon-fiber panels. The Hard Core package offers a 40 lb. weight savings and provides ultimate street-legal race-ready performance.

 

World-class Ride and Handling
 

The all-new 2008 Dodge Viper SRT10 ACR is specifically modified and tuned for track performance. The ACR suspension includes coil-over racing dampers from KW Suspensions that are adjustable for damping and ride height. The shocks are two-way adjustable without removing the wheels — a timersaver on the track — and they include a large range for compression and rebound. The KW dampers and forks are machined from solid aluminum billet, feature spherical bearing mounts, and are optimized to minimize weight and maximize performance.
 

The 2008 Dodge Viper SRT10 ACR features a new front stabilizer bar for increased roll-stiffness.
 

Lightweight forged aluminum Sidewinder wheels are optimized by using Finite Element Analysis to achieve a lower rotating unsprung mass. Finished in gloss black paint, they wear Michelin Pilot Sport Cup DOT-approved (street-legal) race tires, providing enhanced grip on the track.
 

Track performance is maximized in the 2008 Dodge Viper SRT10 ACR via several weight-savings initiatives. The savings were achieved with the Michelin Pilot Sport Cup Tires, Sidewinder lightweight wheels and StopTech brake rotors. With the aerodynamic and suspension elements, the 2008 Dodge Viper SRT10 ACR is 40 pounds lighter than the Viper SRT10 coupe. The optional Hard Core package further reduces the weight by another 40 pounds, for a total weight savings of 80 pounds.

 

Benchmark Braking
 

The Viper SRT10 benchmark brakes are taken to the next level in the 2008 Dodge Viper SRT10 ACR. StopTech two-piece, slotted lightweight rotors combine with the Viper SRT10’s Brembo calipers to reduce rotating inertia and unsprung mass, improve brake cooling, and significantly reduce fade even under extreme conditions. The StopTech rotors feature a patented curved-fin design, a key element in improving brake cooling. The StopTech brake rotors combined with the Michelin Pilot Sport Cup Tires and Sidewinder lightweight wheels combine to reduce 60 pounds of unsprung, rotating mass. The 2008 Dodge Viper SRT10 ACR stops from 60 mph in less than 100 feet.

Standout Powertrain
 

The 2008 Dodge Viper SRT10 ACR utilizes the Viper SRT10’s new 8.4-liter aluminum V-10 engine that produces a ground-shaking 600 horsepower and tire-smoking 560 lb.-ft. of torque. It features a deep-skirted V-10 aluminum engine block, cylinder heads equipped with Computer Numerically Controlled (CNC)-shaped combustion chambers, large valves and Variable Valve Timing (VVT). VVT Electronically adjusts when the exhaust valves are open and closed according to engine speed and load, allowing the engine to "breathe" cleaner and more efficiently.
 

The two-piece intake manifold combines cast aluminum lower with smooth runners for better air flow, bolted to a die-cast aluminum upper plenum. A revised air-cleaner box with a low-restriction filter sends air through a dual electronic throttle control into the intake module.
 

The air-fuel mixture in the cylinders is ignited by platinum-tip spark plugs fired by individual plug coils mounted on the cylinder-head covers.
 

Within the cylinders, pistons are equipped with large-diameter floating pins with bronze bushings for high-load capability. Forged powder-metal connecting rods are secured with aircraft-quality fasteners for increased fatigue strength.
 

Engine lubrication is managed by the large oil pump and a swinging oil pickup adapted from Viper competition engines, to ensure proper oil pressure in high-rpm and hard-cornering conditions.
 

The 2008 Dodge Viper SRT10 ACR sports the latest evolution of the Tremec T56 six-speed manual transmission known as the TR6060. Power is transmitted to the rear wheels via a GKN ViscoLok speed-sensing limited-slip differential.

 

Manufacturing
 

The 2008 Dodge Viper SRT10 ACR will be hand built at the Conner Avenue Assembly Plant in Detroit.
 

The 2008 Dodge Viper SRT10 ACR will arrive in showrooms in the second quarter of 2008 at a U.S. Manufacturer’s Suggested Retail Price (MSRP) of less than 0,000. Complete pricing information will be released at a later date.
