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 Honda 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 Honda 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.
Body
The Honda S2000 is an open-topped, two-seat roadster with a near perfect 50/50 weight distribution. The Honda 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 Honda 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.
Safety Features
The Honda 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.
