New Audi engine name badges: what they mean

Audi has replaced its badges showing engine size with a new system showing their power: we explain all

Size no longer matters - at least when it comes to engines, says Audi. The German manufacturer has announced a new way of labelling the engines in its cars, which is completely different from its current system, based on the size of the engine.

It should make it easier for customers to compare electric cars with conventional models.

In autumn 2017, the manufacturer started ditching the digits that showed the engine size - such as 2.0 for a 2.0-litre engine - and replaced them with a number that indicates the car’s power. From summer 2018, all Audi models had shifted to the new format.

This new number doesn’t display the exact power of the engine, but is an indication of its output, and rises as power increases, so the higher the number, the more power you can expect.

For example, the numeral ‘25’ will appear on the rear of all models whose engines produce less than 107 horsepower (hp). Higher up the power range, ‘45’ will represent power outputs of between 230hp and 252hp. Full information is in the table at the bottom of this page

Audi has taken this move in response to increasingly advanced engine technology that can mean that a small 1.0-litre engine can be more powerful than a 1.4-litre motor that’s 40% larger, making engine size less useful to buyers. Much of this has to do with the move to turbocharged engines that can produce more power than you'd normally expect for their size.

An increasing number of new cars now feature turbocharged engines, as this can be an effective way of boosting power from a small engine without increasing fuel consumption too much. With manufacturers facing ever tougher emissions rules, the need for the best balance of economy and performance has seen greater use of turbocharging, meaning that engine size has less relation to power output than it used to, when very few cars featured power-boosting turbochargers.

The system will also provide a standardised way of comparing petrol, diesel, hybrid and electric cars, which will all carry the same badging at the back.

The new badge system will combine the existing model name for example, A4) and engine type (for example, TDI for diesel TFSI for petrol and e-tron for an electric motor) with the two-digit number indicating power.

So the least-powerful Audi A1, which is currently called the A1 1.0 TFSI 95PS - with PS referring to the German name for horsepower, also known as hp - will become the A1 25 TFSI. At the other end of the power spectrum, the A8 3.0 TFSI 340PS will become the A8 55 TFSI.

The new naming system has now been rolled out across the Audi range with the first model to carry it being the Audi A8, on sale from autumn 2017. All new Audis, therefore, now use the new system, but the company continues to offer a ‘delete badge’ option, which will remove the power figures for customers who'd rather not have them emblazoned on the back of their car.


New Audi engine badges: provisional information

Audi has published the range of power outputs that each of its new badges represents, but this is expected to change, as there are gaps in the power output range. For example, it’s not clear what badge a car with 130hp would carry.
