Our engines explained

With the arrival of the Audi e-tron, Audi will now be standardising the engine descriptions on models in the range based on a car's power output rather than the typical litre capacity value.

The names of the model series, from the Audi A1 to the Audi Q7, will remain the same but now a combination of two numbers will replace the various type designations previously used. These numbers will stand for the vehicle's power output and will apply to petrol, diesel and e-tron models.

Why the change?

More of our models are being powered by alternative fuel like electric and hydrogen and the motors powered by these fuel sources do not have the same CC as a traditional combustion engine. The new naming convention will make it easier to compare power output from a range of different fuel types.

Vehicles will now be classified into different performance levels identified by a two-number combination and this number will appear on the vehicle along with the engine technology - TFSI, TDI or e-tron. The numbers increase in increments of five and will represent the hierarchy within the range. This change should also make it easier to identify engines with more than one power output.

The two digit number is based on the car's kilowatt (kW) power output range as shown in the table below. S, RS and R8 models will all retain the existing naming to reference their position at the top of the Audi range.
