The Viper was initially conceived in late 1988 at Chrysler's
Advanced Design Studios. The following February, Chrysler president
Bob Lutz suggested to Tom Gale at Chrysler Design Center that the
company should consider producing a modern Cobra, and a clay model
was presented to Lutz a few months later. Produced in sheet metal
by Metalcrafters, the car appeared as a concept at the North
American International Auto Show in 1989. Public reaction was so
enthusiastic that chief engineer Roy Sjoberg was directed to
develop it.
Sjoberg selected 85 engineers to be "Team Viper", with development
beginning in March 1989. The team asked the then-Chrysler
subsidiary Lamborghini to cast a prototype aluminum block for the
sports car to use in May. The production body was completed in fall
1989, with a chassis prototype running in December. Though a V8
engine was first used in the test mule, the V10 engine, which the
production car was meant to use, was ready in February 1990.
Official approval from Chrysler chairman Lee Iacocca came in May
1990. One year later, Carroll Shelby piloted a pre-production car
as the pace vehicle in the Indianapolis 500 race. In November 1991,
the car was released to reviewers with the first retail shipments
beginning in January 1992.
The fourth generation Viper was released for the 2008 Model Year
and introduced a 8.4 Liter V10 engine with 600 HP and 560 lb�ft of
torque via better flowing heads with larger valves, Mechadyne
cam-in-cam variable valve timing on the exhaust cam lobes, and dual
electronic throttle bodies.Electronic engine control was developed
by Continental AG and can monitor the crankshaft and cylinder
position up to six times during each firing and has 10 times more
processing power than the previous unit.
The Tremec T56 transmission was replaced with a new Tremec TR6060
with triple first-gear synchronizers and doubles for higher gears.
The Dana M44-4 rear axle now had a GKN ViscoLok speed-sensing
limited-slip differential that greatly helps the tires in getting
grip under acceleration.
The ACR (American Club Racer) is a track-focused, performance
oriented variant that combines Dodge's racing DNA into the road
legal Viper. A carbon-fiber front splitter, front canards and an
adjustable carbon fiber rear wing make the car more responsive
around corners and enables it to generate 1,000 lbs of downforce at
150 mph. The front splitter includes stainless steel tension cables
that provide enough support to absorb the energy from minor upward
deflections, in terms of aerodynamics, the car made good use of the
high-performance autoclaved carbon-fiber to reduce weight. The
splitter and dive planes feature a clear-coated carbon-fiber weave
for an aggressive look. Lightweight filler panels replace the front
fog lamps and gloss black lightweight forged aluminum Sidewinder
wheels with Michelin Pilot Sport Cup DOT-approved race tires finish
off the exterior of the car. The ACR features a signature two-tone
paint scheme with a black center section. Five colors were
available especially for the ACR variant; Viper Red, Viper Black,
Viper Violet, Viper Bright Blue Metallic, and Viper Very Orange.
The interior is driver focused with the deletion of the audio
system in favor of a lightweight cover on the dash board that can
be used to mount a lap-timer, deletion of the floor mats, underhood
silencer pad and the tire inflator in the optional "Hard Core"
package in order to save weight. The use of carbon fiber along with
the minimalist interior make the car 80 lbs lighter than the
standard coupe when equipped with the Hard Core package.The ACR
features a suspension system that includes adjustable coil-over
racing dampers from KW Suspensions and two-way adjustable shocks.
The dampers and forks are made from solid aluminum billet and are
optimized for increased weight reduction and performance. Stopping
power comes from StopTech two-piece, slotted lightweight rotors
combined with Brembo calipers. This setup reduces rotating inertia
and unsprung mass, improves brake cooling, and significantly
reduces fade even under extreme conditions. Due to the improved
brakes, the car stops from 60 mph in less than 100 feet. Braking
from 80 mph is shorter by 11 feet than the standard car,
steady-state lateral grip has improved by 0.11g, and improved
transient dynamics through the slalom bump up the average speed by
3.2 mph.
The ACR was put through its paces at the Nuerburgring and clocked
in a record time of 7:22.1. Car and Driver magazine tested Viper's
track performance, and managed a fast sub-3 minute lap time around
Virginia International Raceway. The Viper's time, despite hot
weather, was faster than the Corvette Z06, Ford GT, Nissan GTR,
Porsche 911 Turbo, 911 GT3, and 911 GT2, and Audi R8.
Performance specs are:
0-60 mph: 3.79 sec.
0-100 mph: 7.6 sec.
quickest quarter mile: 10.92 sec @ 129.79 mph
top speed: 202 mph
There isn't another ACR on the market quiet like this one. Finished
in Viper Very Orange, this ACR only HAS 34 MILES since new and has
never been dealer prepped. It is completely in the wrapper with
"remove by dealer" tags still in tact. It has the options Hardcore
Package making it even lighter and this exact combo is 1 of 6.
The Viper is deeply associated with iconic legends Carroll Shelby
and Lee Iacocca and is its value and collectability is expected to
continue to rise. This ACR Viper is an amazing, investment grade
collectible at a great value.
