Default 2008 Honda S2000 - Introduction

Torrance, Calif. - Aug 15 —

Overview


The Honda S2000 represents the purest expression of Honda fun-to-drive DNA
with its 2-seat, open-topped roadster configuration and sophisticated front-engine,
rear-wheel-drive platform. As a true sports car that can serve as a practical
and fun daily driver and also feel equally at-home on a racetrack, this concept
further evolves with the addition of a club racer-inspired S2000 CR to the Honda
lineup.


The S2000 CR (CR for "Club Racer") introduces more track-oriented
suspension settings, aerodynamic-enhancing bodywork, a removable hardtop, higher
rigidity and reduced weight to the S2000 formula. The added features are designed
to appeal to enthusiasts who enjoy open track day events and also provide a
more ideal starting point for racers who modify the S2000 for competition in
club racing events.


"Open track days and club racing events have rapidly gained popularity
as new racing venues and dedicated organizations make track time increasingly
more attainable," said John Mendel, executive vice president of American
Honda Motor Co., Inc. "The S2000 CR is designed as the ideal car to drive
to the track, drive at the track and drive home from the track with minimal
fuss."


S2000 Summary:



  • 2.2-liter, DOHC, 16-valve, VTEC 4-cylinder engine

S2000


As a quintessential roadster-style sports car, the S2000 is a performance
icon for the Honda brand that combines racetrack-inspired performance with everyday
usability. The front engine, rear-wheel-drive S2000 rewards driving enthusiasts
with a potent 2.2-liter, 16-valve DOHC VTEC® 4-cylinder engine and a precise,
short-throw 6-speed manual transmission, along with tenacious handling and an
ideal 50/50 weight balance.


The renowned high-revving engine delivers 237 horsepower at 7800 rpm and 162
lb-ft. of torque at 6800 rpm. Perfectly complementing the engine's output characteristics
is a compact, longitudinally-mounted, close-ratio 6-speed manual transmission
that features a direct linkage for precise shifting and quick throws. Additional
performance features include a front and rear double wishbone suspension, electric
power steering and a torque-sensing limited slip rear differential.


The S2000 comes with 17-inch aluminum alloy wheels, ABS and Vehicle Stability
Assist (VSA). (VSA is the Honda brand name for electronic stability control.)
While VSA serves to effectively enhance driver control during acceleration,
braking, and cornering, the system can be disabled with the touch of a button
when conditions warrant. Air conditioning and an AM/FM/CD audio system are standard
equipment on the S2000, optional on the S2000 CR for weight savings.


New for 2008, the S2000 has revised spring and damper tuning that subtly influences
steering feel and high speed vehicle behavior. Inside, the minor changes include
revised instrument panel meters and minor revisions to the seat design. Also,
a Tire Pressure Monitoring System (TPMS) has been added.


S2000 CR


The S2000 CR is an entirely new trim level for 2008. The lighter, stiffer
and more aggressive overall design is engineered to maximize the S2000's
potential on a racetrack with the goal of substantially-improving track times,
chassis balance and feel. Compared to the S2000, the factory-tuned S2000 CR
provides more aggressive and track-oriented suspension settings, increased body
and chassis rigidity, overall weight reduction, and aerodynamic spoilers tuned
for reduced lift and enhanced chassis balance at high speeds. A removable aluminum
hardtop replaces the convertible soft top.


The aerodynamic package reduces lift through large and specially-tuned front
and rear spoilers. Exclusive chassis features include a quicker steering ratio,
more aggressive Bridgestone Potenza RE070 tires (in place of RE050 tires), a
larger rear tire size, firmer springs and dampers, larger stabilizer bars and
the S2000's new wheel design in Kaiser Silver. A rear body brace has been
added to the area previously occupied by the soft top, resulting in additional
rigidity. Relative to the base 2008 S2000, cumulative weight savings total 51
pounds (hardtop installed) and 99 pounds (hardtop removed).


The exclusive interior is highlighted by black fabric seating surfaces with
yellow stitching, a unique spherical aluminum shifter and carbon fiber-style
trim panels. To save weight, air conditioning and an AM/FM/CD audio system are
only available as factory-installed optional equipment.

Powertrain


The 2.2-liter, DOHC VTEC 4-cylinder engine produces 237 horsepower and 162
lb-ft. of torque while meeting California's Low-Emission Vehicle 2 (LEV-2)
standards. Honda's innovative VTEC advanced variable valve-timing system
operates the engine's 16 valves in both intake and exhaust modes. This
system is compact and tailored to the high-output, high-rpm operating characteristics
of the S2000 engine. Torque and horsepower are optimized over the engine's
entire operating range to simultaneously provide low-end power and top-end performance
near the engines 8000 rpm redline. The S2000 is capable of accelerating from
0-60 mph in less than six seconds.


The aluminum-alloy cylinder head maximizes space efficiency with a compact
gear and chain-drive system for the dual overhead camshafts. The ancillary drive
system for the alternator, water pump and air-conditioning compressor also use
a space-efficient design.


The engine's highly rigid, aluminum-alloy cylinder block features long-wearing
FRM (Fiber-Reinforced Metal) cylinder liners.


ightweight pistons are made of forged aluminum alloy and the forged-steel connecting
rods and crankshaft are heat-treated for added toughness. Numerous friction-reduction
techniques, such as, roller-bearing cam followers and advanced bearing materials,
are used in the engine.


A large-capacity, low-restriction intake system and low back-pressure exhaust
system contribute to the engine's overall efficiency and help create the
S2000's audible performance demeanor. (The S2000 CR sport muffler is tuned
for a more aggressive exhaust note.) The exhaust system uses a high-efficiency
metal-honeycomb catalyst. A direct-ignition system and Honda-programmed multi-point
fuel injection contribute to the S2000's engine achieving its LEV-2 status.


A 6-speed, manual transmission uses closely-spaced low gear ratios on gears
one through five, and a "tall" sixth speed gear for relaxed highway
cruising (65mph = 3500 rpm). The transmission is a compact design and features
a direct mechanical shift linkage with short throws between each gear. A Torsen
limited-slip differential distributes torque to both rear wheels simultaneously
or variably as traction conditions permit.


Body


The S2000 is an open-topped, two-seat roadster with a near perfect 50/50 weight
distribution. The S2000 uses steel body construction with the exception of the
hood, which is aluminum. The body and frame are a hybrid monocoque structure.
The "High X-Bone Frame" is formed by the body's high side
sills, and diagonal (X) bracing underneath the body. A large central tunnel
runs down the center of the cockpit. The tunnel serves as the backbone and main
load-bearing structure for the vehicle, as well as a housing for the transmission
and driveshaft.


The exterior styling of the S2000's body is designed to appear angular,
modern and sleek. The long hood and flared front fenders create the impression
of lowness and mass. High-intensity discharge (HID) projector headlights highlight
the front of the vehicle, while the taillight design follows a similar theme
with large, round multi-LED taillights set in clear-lens housings.


The S2000 CR adds extensive aerodynamic body work that functions to significantly
reduce lift and enhance chassis balance at high speeds. An underbody front spoiler
and a trunk lid-mounted rear spoiler combine to lower the Coefficient of Lift
(Cl) by as much as 70-80 percent depending on the roof configuration. Downforce
is created by the rear spoiler when the hardtop is installed as the contour
of the roof is designed to influence aerodynamics at the rear of the vehicle.


Chassis


The S2000's front and rear double wishbone suspension systems are a
compact in-wheel design, similar to the type used on racing cars. At each wheel,
upper and lower A-shaped wishbone links carry suspension loads directly to the
subframes. Front 215/45 R17 87W and rear 245/40 R17 91W (255/40 R17 94W on CR)
tires are mounted on newly-designed and lighter weight 17-inch alloy wheels.
The 11.8-inch vented front brake discs and 11.1-inch solid rear brake discs
are calibrated to provide world-class stopping power and a solid, linear brake
feel. Coil springs and mono-tube, gas-pressurized dampers (remote reservoirs
in the rear) are used at each wheel. Front and rear stabilizers help keep body
roll to a minimum.


Electronic stability control is provided through the VSA system, and an ABS
system is standard equipment. An electrically-assisted power steering system
provides more power steering assist at low speeds for ease-of-maneuvering. As
vehicle speed increases, less power assist is supplied, giving the steering
a more direct feel.


For 2008, the S2000 suspension has been tuned with new spring, damper and stabilizer
bar settings to further enhance road-holding and steering feel. The S2000 CR
suspension tuning goes even further by taking advantage of body rigidity enhancements
made possible with the exclusive removable hardtop configuration and by adding
stiffer springs and sway bars, and firmer dampers. Specially-developed steering
gearbox stiffeners on the S2000 CR provides an even more direct, reflexive feel,
and is further supplemented by a quicker steering ratio of 13.8:1 (compared
to 14.9:1 for the S2000).


Interior


The S2000's driver-oriented interior is designed to be functional in
much the same way as a purpose-built racecar with excellent outward visibility
and simplicity of controls. High sides reinforce the cockpit-like feel of the
interior. The seats contour to provide excellent lateral support during aggressive
turns. Controls such as the steering, brakes and clutch, operate with a high
level of precision and a direct, commanding feel. The aluminum and leather-wrapped
shift knob, racing-inspired digital instrument display and engine-start button
further highlight the vehicle's racing pedigree.


The list of comfort and convenience features includes a power-operated convertible
top that opens or closes in approximately six seconds (replaced by a removable
aluminum hardtop on the S2000 CR), power door locks, power windows, cruise control,
Immobilizer Theft-Deterrent System and keyless entry for the doors and the trunk.
The following features are standard on the S2000 and available on the S2000
CR: air conditioning with micron air filtration and an AM/FM/CD audio system
with eight speakers (including four speakers located in the roll bar hoops behind
the seats) and remote-operated audio controls.


For 2008, a few noteworthy changes have occurred to the interior on all S2000
models. The instrument panel has a revised meter design for the fuel and temperature
gauges, adding to the aesthetics of the display. Specifically, the fuel and
temperature meters now reside along the arc formed by the tachometer instead
of a semi-circle configuration below and to the right of the tachometer.


The S2000 CR interior follows traditional racecar themes with fabric seating
surfaces highlighted by yellow stitching. Synthetic suede bolsters enhance lateral
grip. A spherical aluminum shift knob on the S2000 CR rests 12.6 mm lower for
a 6 percent reduction in shift stroke compared to the regular S2000 cylindrical
shift knob (aluminum/leather wrapped). Additionally, shift load effort increases
by 10 percent for even more direct feedback when engaging a gear. The S2000
CR instrument panel meters include a "peak-power indicator." When
the engine is operating at peak power, a round, green light illuminates to the
right of the digital speedometer.


Safety Features


The S2000 has dual-stage, dual-threshold front airbags (SRS) for the driver
and passenger, three-point seat belts with load limiters and pre-tensioners,
roll bar hoops and reinforced windshield posts. For pedestrian safety, the hood
hinges and windshield-wiper pivots are designed to collapse and minimize the
severity of a head injury to a pedestrian. Vehicle Stability Assist, ABS and
a tire pressure monitoring system are standard equipment.


S2000 Background


The design and engineering concept for the S2000 is to deliver race-car-like
performance and handling-something an enthusiast driver could use and
enjoy, even in everyday driving situations. In addition, the S2000 is intended
to be a modern, socially-responsible automobile with low emissions. The S2000's
roadster layout also captures the spirit of the legendary high-performance sports
cars of the past, as well as Honda's very first sports car, the S500 roadster.


However, the S2000 makes no attempt to be a retro sports car. It is a unique,
Honda interpretation of a modern sports car - with high performance, state-of-the-art
technology, style, and Honda durability, quality and refinement.


Manufacturing


The Honda S2000 is manufactured at the Honda Motor Co., Ltd., Suzuka factory
in Japan on an exclusive production line.
