What is the Audi car with the largest displacement?

[NovaDella]

Audi's models with the largest displacement are the Audi Q7 W12 and R8 V10. Displacement and Cars: The volume of space that the piston moves from the top dead center to the bottom dead center is called the cylinder displacement; if the engine has several cylinders, the sum of the working volumes of all cylinders is called the engine displacement. It is generally expressed in liters (L). Engine displacement is one of the most important structural parameters, which represents the size of the engine more than the bore and the number of cylinders. Many indicators of the engine are closely related to the displacement. Displacement Classification: The classification of car levels in China is determined by the size of the displacement. The displacement of a mini car is less than or equal to 1.0L; the displacement of an ordinary car is in the range of 1.0-1.6L; the displacement of a mid-size car is in the range of 1.6-2.5L; the displacement of a mid-to-high-end car is in the range of 2.5-4.0L; the displacement of a high-end car is greater than 4.0L.

I remember when I was a kid, my dad took me to an auto show, and the A8L W12 on the Audi stand left a deep impression on me. The salesperson said it was powered by a 6.0-liter W12 engine, the largest in Audi's history. This car drove like a luxury yacht, with the 12 cylinders running incredibly smoothly and almost no noise. However, such a large displacement came at a cost—city driving easily consumed over 20 liters per 100 km, and filling up the tank would cost hundreds in no time. Looking back now, I feel quite nostalgic, especially since Audi discontinued this high-displacement engine in 2019, citing increasingly strict environmental regulations. Today, the most powerful Audis are probably the R8 or RS6, but their 4.0T engines still haven't broken the 6.0-liter record.

When I was on a business trip in Germany, I visited the Audi headquarters. Their engineers told me that the largest displacement engine in Audi's production cars is the A8L W12. That 6.0-liter engine has a unique layout—two V6 engines forming a W-configuration, fitting snugly into the engine bay. People who've driven it say it's as gentle as a cat at low speeds but turns into a beast when you floor the accelerator. But as you know, the automotive industry is shifting toward electrification. The last time I drove the new Audi e-tron GT, even though it's an electric car, its acceleration was faster than the old W12. At the end of the day, the effortless power of a large-displacement naturally aspirated engine is still irreplaceable. It's a shame that nowadays, even buying a used W12 car means maintenance costs high enough to purchase a new domestic car.

I've worked on several Audi A8L W12 models, and that 6.0-liter engine is truly massive. These large-displacement engines are primarily used in top-tier flagship models, with the W-cylinder arrangement designed to save space. But during repairs, disassembly is particularly troublesome—even changing spark plugs requires removing half the engine bay. Nowadays, Audi dealerships mainly promote the EA888 2.0T engine, which is easier to maintain and more fuel-efficient. If you're asking about current models, the 4.0T twin-turbo in the RS Q8 is already plenty powerful—you don't really need that much displacement for regular road use.
