History

The Honda S2000 is a roadster manufactured by the Japanese automaker Honda Motor Company. Launched in April 1999, the car was created to celebrate the company's 50th anniversary and continues the tradition of the company's previous lightweight roadster "S" cars, the S500, S600 and S800. Prices in the United States start at US$34,300.

Current Production

Design and Construction

The S2000 features a front-mid-engine, rear wheel drive layout with power being delivered via a Torsen limited slip differential mated to a six-speed manual transmission.

The car is constructed using an X-bone monocoque frame which is extremely rigid, improving passenger safety and handling. Other features include independent double wishbone suspension, electrically-assisted steering and integrated roll hoops.

The S2000 comes with an electrically powered vinyl top (cloth-lined on the inside and the vinyl exterior is often mistaken for canvas because of its texture), and an OEM hardtop is also available.

Models

The car was originally launched in 1999 as a 2000 model, given the chassis designation AP1. The 2000 model featured 16" wheels with Bridgestone Potenza S-02 tires.

For the 2002 model year, suspension settings were revised and a smaller glass rear windscreen introduced. The plastic rear window was replaced with glass; an electric defroster was added. Other updates included slightly revised taillamps, an upgraded stereo, and a revised engine control unit (ECU).

From its inception in 1999 to 2003, S2000s were manufactured at Honda's Takanezawa, Tochigi plant, alongside the Honda NSX supercar and Honda Insight hybrid. In 2004 production moved to the Suzuka plant.

The 2004 model introduced newly designed 17" wheels and Bridgestone RE-050 tires along with a retuned suspension that reduced the car's tendency to oversteer. The spring rates and shock absorber damping were altered and the suspension geometry modified to improve stability by reducing toe-in changes under cornering loads. In addition, cosmetic changes were made to the exterior with new front and rear bumpers, revised headlight assemblies, new LED tail-lights, and oval-tipped exhausts. At the same time, Honda introduced a 2.2 L variant to the North American market. The revised car was given the chassis designation AP2.

The 2006 model introduced a drive by wire throttle, Vehicle Stability Assist system, new wheels, and one new exterior color, Laguna Blue Pearl. Interior changes included revised seats, additional stereo speakers integrated into the headrests, and additional headrest padding where previous seats had helmet depressions and screens. The 2.2 L engine was also introduced to the Japanese market during this time.

In 2007 two exterior colors (Suzuka Blue and Sebring Silver) were dropped, while the Grand Prix White color was re-introduced with a black, red, and gray interior.

The 2008 model year will mark the first time the S2000 will be offered in more than one trim level. In addition to the base model, Honda will offer a new "club racer" version of the S2000, distinguished by reduced weight, fewer amenities, and a claimed increase in performance. The S2000 CR made its world debut at the 2007 New York International Auto Show on 4 April 2007. Changes for the CR include a quicker (lower-ratio) steering rack, stiffer suspension and all-new Bridgestone Potenza RE070 tires. Rear tires are widened from 245/40R-17 to 255/40R-17 on the CR. A revised body kit, comprised of a redesigned front clip, rear bumper, and a large spoiler, have been wind-tunnel tested and are claimed to produce positive downforce at speed. The power folding soft top was removed and replaced with additional chassis bracing topped off with a tonneau cover, while the optional removable non-structural hard top became a standard feature on the CR. Finally, in an effort to reduce weight and lower the center of gravity, the spare tire is omitted, and air conditioning and a stereo are offered only as options. Net weight savings is 90 pounds relative to the standard model (and before the addition of the hardtop). The engine in the S2000 CR is unchanged from the standard trim.

The new Honda S2000 CR became available in the fall of 2007. The price starts at $36,300 USD. Production volume of less than 2,000 units is expected. The redesigned five-spoke wheels shown on the S2000 CR concept will come standard on all S2000s, with bright silver on the base model wheels and a gunmetal color on the CR wheels.

Powertrain

The S2000 (2000 to 2003 models) initially came equipped with a 2.0 L (1997 cc) F20C inline 4 cylinder DOHC-VTEC engine producing 243 PS (179 kW, 240 hp) at 8,300 rpm and 153 ftlbf (208 Nm) of torque at 7,500 rpm, though European versions were rated slightly lower at 240 PS (177 kW, 237 hp) and the Japanese models were quoted with 250 PS (184 kW, 247 hp) at 8,600 rpm due to a small difference in engine compression ratio.

Honda introduced a variant of the F20C engine to the North American market in 2004. Designated F22C1, the engine's stroke was lengthened, increasing its displacement to 2.2 L. At the same time, the redline was reduced from 9,000 to 8,000 rpm with a cutout at 8,200 rpm, mandated by the longer travel distance of the pistons. Peak torque was increased by 6% to 162 ftlbf (220 Nm) at 6,200 rpm, and the F22C1 was quoted by Honda as having more torque at lower rpm than the F20C, although power output was the same. Initially, the F22C1 was intended only for the North American market, but it was also introduced in Japan in 2006 with specified power of 242 PS (178 kW, 239 hp). Other markets continued with the 2.0 L version.

In part because of its high-revving nature for a car engine (9,000 rpm rev limit for the 2.0 L and 8,200 rpm for the 2.2 L engines), the S2000 achieves the highest specific power per unit volume of any mass-produced naturally-aspirated automobile piston engine, producing 123.5 hp (92 kW)/L in the Japanese F20C (beating the older record holding Nissan Pulsar VZ-R N1 by 0.375 hp/L (0.28 kW)/L). The compact and lightweight engine, mounted entirely behind the front axle, allows the S2000 to obtain a 50:50 front/rear weight distribution and lower rotational inertia than would otherwise be possible.

In conjunction with its introduction of the F22C1, Honda also changed the transmission gear ratios by shortening the first four gears and lengthening the last two. Another change was the inclusion of a clutch release delay valve to improve drivetrain longevity by reducing shock loads.

The 2008 CR will include a special yellow and black interior to go with an aggressive body kit.
