2016 Audi A3 to get 1.8 TFSI with cylinder deactivation

April 30, 2015

The MQB-platform based third generation Audi A3 has been out in the market since 2012 and will receive a mid-life facelift in 2016. One of the notable changes in the facelift would be in the engine compartment. The 1.8-litre TFSI petrol engine will be enhanced with the addition of what Audi calls ‘cylinder on demand’ technology, or cylinder deactivation in simple words, says a new report from Autoevolution.

The technology is dubbed ‘Active Cylinder Technology’ by VW. The currently sold A3 with the smaller 1.4-litre engine does feature this cylinder deactivation technology.

The A3 will be the first car to use a 1.8-litre engine with this technology and although this technology will most likely lead to the car getting more expensive, the fuel economy improvement will be worth every extra penny. The cylinder on demand technology will shut off two of the four cylinders over a low engine speed.

VW says that 70% of the EU driving cycle is between 25 Nm and approximately 100 Nm. When the driver presses the accelerator pedal hard, the two cylinders on standby start working immediately without a noticeable transition. A monitoring software deactivates this technology during sport driving. Whether two or four cylinders are active can be seen through an indicator in the instrument cluster. How exactly and with what features the technology will be made available on the A3 1.8 TFSI is not specified, but it should be somewhat similar to this.
