Model Year 2006

The 39th Tokyo Motor Show, held from October 22 to November 6, 2005, at Makuhari Messe in Chiba, Japan, had dozens of cars and motorcycles on display, but it is the new S2000, equipped with even more advanced features than ever before, that shared the Motor Sports Zone stage with a rare close-up look at Honda’s F1 and IndyCar Series racers.

• MSRP increased to $34,050 and shipping to $550 for a total of $34,600.
• Drive-By-Wire Throttle System. Ues a computer sensor to input throttle as opposed to pulling on the throttle cable. It's all electronic. this has allowed for several other changes. The cruise control actuator, control unit, Idle air control motor have all been eliminated. Many early reports say the DBW is pretty seamless, with no delay to rev match on a downshift.
• Vehicle Stability Assist (VSA) with traction control. A combination of computer controlled throttle and individual wheel braking to control sudden changes in vehicle behavior. VSA has a turn-off switch where the defrost button (moved) used to be.
• 20 lbs heavier
• Redesigned road wheels
• Redesigned steering wheel
• New color, Laguna Blue
• Daytime running lights (DRL)
• Brake Assist, which helps drivers apply full braking pressure in an accident avoidance situation via the ABS actuator. Braking pressure is maintained momentarily after the driver's initial braking action to help the driver stop promptly. It deactivates when the driver releases pressure on the brake pedal
• Basic warranty is 3 year/36,000 but the power train was extended to 5 years/60,000 mile
• Exterior temperature gauge
• New seats; they no longer have seat back pocket and headrest speaker system is gone
• 4 of the 8 speaker audio system are integrated roll bar speakers
• Sebring silver and white only come with a black interior
• CARB emissions rating is now LEV-2
• Passenger-side airbag cutoff
• IAC Valve has been eliminated, along with the cruise control hardware; it is all controlled by the ECU for the DBW system. A gas pedal cable runs into the engine compartment to an actuator. From there it's electronic.
• New intake manifold, intake support bracket, and injector cover. With the new intake manifold casting there are no additional vacuum ports on the manifold. The intake air temp sensor has been relocated to the air inlet tube.
• Only one cam sensor
• New style map sensor
• IAT sensor has moved to the rubber intake tract
• Differential now has a breather box mounted behind it
• Fuel line at engine is now a quick-release type
• Air pump, associated lines and and control valve, have been eliminated
• Weight/and or/position sensors mounted in the seats
• Fan switch in the radiator has been replaced with a second CTS, in turn the fans are now computer controlled
• HO2S in the header is now referred to as an Air fuel ratio sensor
• If you leave the gas cap loose, you'll get a "CHECK GAS CAP" warning, displayed in the outside temp display
• Return-less fuel system. There is no longer a regulator on the fuel rail, it is built into the fuel pump module in the tank. The injectors, fuel rail, fuel feed lines have all changed. NOTE: Reportedly this makes Supercharger kits for the 00-05 cars incompatible.
• The cylinder head doesn't have injection ports machined. The cylinder head will not swap on the 00-05 cars. (with a stock PCM).
• SRS system. Several new components, front impact sensors have been added, as well as a passengers seat weight sensor. The Passenger airbag now is shut off when someone under a safe weight is in the seat. There is also a driver seat position sensor, which changes bag deployment force based on seat position. The passengers bag shut off indicator is above the radio door. NOTE: Reportedly 00-05 passenger seats will not function with the system, as the weight sensor is built into the seat rails.
• The hemholtz resonator on the exhaust system has changed shape/dimension; they are now oval, instead of round.
• ECM logic/SSD mode. The ECM/PCM performs several functions after the key is turned off and removed. You must wait at least 15minutes after the key is turned off before unplugging the PCM. NOTE: If you unplug the PCM while it's performing the SSD (self shut down) tests you can permanently damage the PCM.
• Maintenance minder system. The previous Maintenance Req'd light has been replaced with a new system. Oil life is calculated based on RPM's and operation conditions to determine oil change intervals.
• Air filter mounting stud has changed, the air filter from a 00-05 will not fit properly in the 06 airbox.
• HP is now stated at 237 - due to the auto industry wide change in how HP is calculated**
