Similar but now quite...

Actually... not exactly the same...

Electronic Stability Control (ESC) is the generic term for systems designed to improve a vehicle's handling, particularly at the limits where the driver might lose control of the vehicle.

Robert Bosch GmbH was the first to deploy an ESC system, called Elektronisches Stabilitätsprogramm (ESP®) that was used first by Mercedes-Benz and BMW in 1995. It was then introduced to the mass market by Continental Automotive Systems under the broader name of Electronic Stability Control, which is now the more common term recognized by the Society of Automotive Engineers, although individual motor manufactures use a range of different marketing names (see below).

Traction control systems, on current production vehicles, are typically (but not necessarily) electro-hydraulic systems designed to prevent loss of traction (and therefore the control of the vehicle) when excessive throttle or steering is applied by the driver. Although similar to the Electronic Stability Control systems, the Traction Control systems don't have the same goal as them.

The intervention can consist of any, or all, of the following:

Retard or suppress the spark to one or more cylinders
Reduce fuel supply to one or more cylinders
Brake one or more wheels
Close the throttle, if the vehicle is fitted with drive by wire throttle.
The brake actuator, and the wheel speed sensors, are the same as that used for anti-lock braking systems.

as far as i know ASR is generally used for different forms of traction control (no stability control) and ESP for stability control (braking one wheel at a time to regain stability when the car slides). ofcourse, i may be wrong :)

225s seem to reduce throttle when the TC kicks in.i think the TC and the ABS on the 225 are the best ever, but the ESP is too intrusive, and should be disableable (? :) ) a la cup/trophy.
