Report: Audi talks cylinder deactivation for new V8 S-Cars

Cylinder deactivation, or systems that disable a particular set of cylinders on an internal combustion engine, has been around for quite some time but has saw limited use because the technology never quite sold. Attempts were made as early as the 1980s for applications on cars, pioneered by General Motors. However, after numerous failures the project was abandoned.

Over the course of the next two decades, systems have been developed by Mercedes-Benz, General Motors again and Chrysler who all have proven that they could work with the right technology. Now, word is that Audi is talking about entering the game with a system of their own.

To showcase Audi’s own version, the Ingosltadt brand said that their new cylinder deactivation system will debut on the new versions of the S6, S7 and S8 next year when they all come out with a new V8.

Supposedly, the system is capable of closing the inlet and exhaust valves on cylinders 2, 3, 5 and 8 when the engine is under low loads or in third gear or higher when speeds are low to moderate.

Audi closed their comments on the system by saying: The “cylinder on demand” system is permanently ready for use, even with the automatic transmission in the “S” mode and the dynamic setting of Audi drive select.
