Honda S2000

From Honda press: The latest version of VTEC, Honda's advanced variable valve-timing system, operates the S2000 engine's16 valves (4 per cylinder). This new system is more compact and tailored to the high-output, high-rpm operating characteristics of the S2000 engine.

A new 6-speed, close-ratio manual transmission has also been designed for the S2000. The transmission is a compact design and features a direct shift linkage with excellent feel and short throws. A Torsen limited-slip differential smoothly delivers power to the rear wheels, regardless of traction conditions.
The S2000 engine and transmission are capable of accelerating the S2000 from 0 -- 60 mph in less than six seconds.
Honda's racing expertise is also evident in the S2000's responsive handling.

The chassis has an ideal 50/50 weight distribution, and the body and frame are a new-design hybrid monocoque/frame structure that forms a rigid, flex-free platform for the S2000's newly developed in-wheel double wishbone suspension system, and plays an important role in helping the S2000 achieve its high "world-class" safety protection. The power steering system is a newly developed, highly responsive, electrically assisted type.
The S2000 powertrain uses a front-engine/ rear-wheel-drive layout. The longitudinally mounted engine is mated to a 6-speed, close-ratio manual transmission. A propeller shaft carries the output of the transmission to a frame-mounted limited-slip differential. The differential drives the rear wheels via separate axle shafts.

The 2.0-liter, aluminum-alloy, inline 4-cylinder S2000 engine produces 240 hp @ 8300 rpm and 153 lb.-ft. of torque @ 7500 rpm. The cylinder head is also made of aluminum alloy and features dual overhead camshafts, 4 valves per cylinder and VTEC (Honda's variable valve-timing system) on both the intake and exhaust valves. Fuel induction is via Honda's sequential, Multi-Point Programmed Fuel Injection (PGM-FI) and the ignition system is a high-voltage, computer-controlled direct type with individual spark coils for each cylinder.

The S2000 engine is 9 percent smaller and 10 percent lighter than a 2.2-liter Prelude engine, and almost as small as a 1.6-liter Civic engine. Yet this compact, lightweight engine (326 lbs.) has the highest specific power output (120 hp per liter) of any normally aspirated 2.0-liter production engine in the world. In addi-tion, the engine's exhaust emissions are so low that the S2000 qualifies as a Low-Emission Vehicle (LEV).
