Audi States Cylinder Deactivation Could Increase Gas Mileage Significantly

There's a relatively new epiphany that's been sweeping across the automotive industry for the past few years: the less cylinders in action an engine has, the better fuel economy it gets. While this may seem incredibly obvious in hindsight, automakers across the globe are working on making smaller, fewer-cylindered, more efficient engines and now Audi is getting in on the action for themselves.


With a new system they're developing for future new Audi vehicles called "cylinder on demand" (COD), they're saying that fuel efficiency can be boosted up to 20 percent higher by deactivating cylinders in the engine, compared to a fully-active mode where all cylinders are pumping.


The system works by cutting off the use of half the cylinders, stopping fuel injection when engine speeds and loads are low, reactivating only upon acceleration. They're currently testing on three engines: a 1.4-liter TFSI COD four-cylinder, a 4.0-liter TFSI COD six-cylinder, and a W12 COD 12-cylinder motor. Right now, the four-cylinder gets about 50 miles to the gallon based on the European standard, so we can't wait to see how high those numbers shoot once the system is perfected and put into production!


We've yet to hear word on when we'll see it in action though, so keep an eye on our blog here for more details as they come.
