What Does Quattro Mean on Audi Cars? (AWD Types by Model)
Quattro is Audi’s name for its all-wheel-drive technology, not a trim level or a single part. It first appeared in the spring 1980 original quattro coupe, and since then Audi has used the name for several different systems: a mechanical centre differential on most longitudinal-engine cars, a clutch-based layout on some compact models, and separate electric motors on electric Audis. Below: what the name means, how each system splits torque, which models have it as of October 2026, and what EPA data show about fuel use.

In everyday use, “quattro” is the word Audi puts on cars that send drive torque to all four wheels. The word is commonly given as Italian for “four”, a point we could not confirm on an Audi page this session, so treat that origin as the usual explanation rather than a sourced one. What Audi’s own pages do say is that quattro means permanent all-wheel drive, and that more than eight million vehicles have been built with quattro technology.
The first thing to correct is the idea that quattro is one fixed design. Audi’s technology portal lists a bevel-gear centre differential, a Torsen differential, a crown-gear differential, a self-locking centre differential, a hydraulic multi-plate clutch, quattro with ultra, a sport differential and electric quattro as separate systems under the same name. That is why one owner’s quattro behaves very differently from another’s.
A Brief History of Quattro
Audi unveiled the first quattro at the 1980 Geneva Motor Show. It was a coupe based on the Audi Coupe (B2), which itself was based on the Audi 80, powered by a turbocharged five-cylinder engine with intercooler rated at 147 kW (200 hp) at 5,500 rpm and 285 Nm at 3,500 rpm, per Audi’s photo archive. Its all-wheel drive was unusually compact: a hollow shaft in the gearbox carried power in two directions, which removed the heavy separate transfer case and front-axle auxiliary shaft that were standard on four-wheel-drive cars of the day.
Later milestones, taken from Audi’s technology portal and its quattro page, run in this order:
- 1980: bevel-gear centre differential in the original quattro, with a manual lock for the centre and rear differentials.
- Autumn 1986: the Torsen centre differential arrives with the Audi 80 quattro, working automatically instead of by a driver-operated lock.
- 1998: an electronically controlled, hydraulically actuated multi-plate clutch debuts in the TT quattro and A3 quattro.
- 2005: the second-generation RS 4 introduces the self-locking centre differential.
- Late 2008: the S4 sedan gets the sport differential at the rear axle.
- Early 2010: the RS 5 brings the crown-gear centre differential, about 30 years after the first quattro.
- 2016: quattro with ultra debuts in the A4 allroad quattro.

How Quattro Works
Every quattro system answers the same question: how much of the engine’s torque goes to the front axle and how much to the rear, and what happens when one axle loses grip. A centre differential lets the axles turn at different speeds in a corner. The design choice is how that differential (or clutch) shifts torque when a wheel slips.
The original 1980 system sent 50 percent of torque to the rear axle in every driving situation, and the driver could lock the centre and rear differentials by hand, first with two Bowden-cable levers between the seats and, from 1981, with pneumatic dashboard switches. Audi’s technology portal notes that because the drive shaft was rigid while locked, ABS (which reached production cars in 1983) could not work during locking phases. The Torsen unit that followed in 1986 removed that limitation: it normally splits 50:50 and can send up to 75 percent to the axle with more traction, locking under load and unlocking when the driver lifts off the throttle.
Types of Quattro Systems
This is the part most explainers skip. The table below compares the quattro systems Audi describes, with the torque split Audi’s own pages give for each. Figures are Audi’s, as published on its technology portal and press site; real splits vary with conditions, and Audi’s two pages for the self-locking and crown-gear units give different maximums, which is why both rows are shown.
| System | Engine layout | Normal split (front:rear) | Maximum split | Example named by Audi | Source |
|---|---|---|---|---|---|
| Bevel-gear centre differential, manual lock | Longitudinal | 50:50 | Not stated; driver locked centre and rear differentials | Original quattro, 1980 | Audi Technology Portal |
| Torsen centre differential | Centre differential, longitudinal | 50:50 | Up to 75% to the axle with better traction | Audi 80 quattro, 1986 | Audi Technology Portal |
| Hydraulic multi-plate clutch | Transverse, compact models | Mostly front | Up to 100% to the rear in some cases | TT quattro and A3 quattro, 1998 | Audi Technology Portal |
| Self-locking centre differential | Longitudinal | 40:60 | Up to 60% front and up to 80% rear (Technology Portal) | RS 4 (2005); Q7 uses a variant in a separate transfer case | Audi Technology Portal, audi.com |
| Crown-gear centre differential | Longitudinal | 40:60 | Up to 70% front, up to 85% rear | RS 5, early 2010 | Audi Technology Portal |
| Sport differential (rear axle) | Adds to a centre system | Splits torque between the two rear wheels | Not a front/rear split | S4 sedan, late 2008 | Audi Technology Portal |
| quattro with ultra | Longitudinal front engine | Front-wheel drive at low load; rear axle connected on demand | More than 70% to the rear under hard acceleration on dry roads (Audi internal measurement) | A4 allroad (2016); A5, A6, Q5 on Audi’s combustion platform (2026 release) | audi.com press release, Technology Portal |
| Electric quattro | Electric Audis, motor on each axle | Varies by model | Not a single figure | Q4 Sportback e-tron, RS e-tron GT, Q8 Sportback e-tron | audi.com quattro page |
Two details are worth knowing. First, Audi says quattro with ultra uses an electronically controlled multi-plate clutch at the transmission output plus a decoupling clutch in the rear differential. When all-wheel drive offers no clear benefit, both open and the car runs as front-wheel drive; Audi says it predicts the need about 0.5 seconds ahead and re-engages in about 200 milliseconds. Second, Audi reports that its test vehicles used on average 0.3 litres per 100 km less fuel than with conventional all-wheel drive, from a test route around Ingolstadt in normal traffic. That is a manufacturer figure, not an independent test.
Audi also says the RS e-tron GT redistributes torque about five times faster than a mechanical quattro, and that the Q4 Sportback e-tron’s front motor engages within a few hundredths of a second. For the compact transverse-engine layout, Audi’s technology portal describes the clutch sitting at the end of the prop shaft in front of the rear differential, fed by two electric pumps that build pressure above 100 bar. It describes that layout for the 1998 TT and A3; we did not verify which current compact models still use it. Audi’s own overview is on its technology portal quattro page.
Does Every Audi Have Quattro?
No. Quattro is a drivetrain name, not a badge every Audi wears, and the EPA’s own listings show it. The table below uses the drive field from fueleconomy.gov for selected Audi model years, read in October 2026. The Q4 e-tron and Q6 e-tron appear in both versions: the cheaper ones are rear-wheel drive, and the quattro versions are all-wheel drive.
| Model year and name (EPA listing) | EPA drive type | Combined mpg (mpge for EVs) |
|---|---|---|
| 2024 A3 | Front-wheel drive | 32 |
| 2024 A3 quattro | 4-wheel drive | 30 |
| 2024 Q4 40 e-tron | Rear-wheel drive | 103 |
| 2025 Q4 45 e-tron | Rear-wheel drive | 115 |
| 2025 Q6 e-tron (19 inch wheels) | Rear-wheel drive | 100 |
| 2025 Q6 e-tron quattro (19 inch wheels) | All-wheel drive | 99 |
| 2025 A5 quattro | All-wheel drive | 26 |
| 2025 A6 quattro | All-wheel drive | 26 |
| 2025 Q5 TFSI quattro | All-wheel drive | 25 |
| 2024 RS 3 (no “quattro” in the EPA name) | All-wheel drive | 23 |
| 2023 TT Coupe (no “quattro” in the EPA name) | All-wheel drive | 25 |
The last two rows show the opposite problem: some Audis are all-wheel drive without “quattro” appearing in the EPA model name, so the name alone is not a reliable test. To check a specific car, look it up on fueleconomy.gov by year and model and read the drive field, or check the owner’s manual and window sticker.

Quattro vs Front-Wheel Drive: Fuel Economy
The cleanest like-for-like comparison in EPA data is the 2024 Audi A3, because the same 2.0 L turbocharged four-cylinder with the same seven-speed automatic comes as both a front-wheel-drive car and a quattro. EPA lists the front-wheel-drive A3 at 29 mpg city, 37 highway and 32 combined, and the A3 quattro at 27 city, 34 highway and 30 combined. EPA’s annual fuel-cost estimate on the same pages is $2,100 for the front-wheel-drive car and $2,250 for the quattro, a difference of $150 a year under EPA’s standard assumptions.
That is roughly a 2 mpg combined penalty on that one model, and it will differ on other Audis and between years, so it is an example, not a rule. It also shows why Audi built quattro with ultra: by running as front-wheel drive when traction is not needed, it aims to narrow exactly this gap. If you are weighing drivetrains more broadly, our front-wheel drive vs all-wheel drive comparison goes through the trade-offs.
How Quattro Compares With Other All-Wheel-Drive Systems
Quattro is Audi’s brand for a family of systems, in the same way other makers use their own names for all-wheel drive. Audi calls itself the most successful premium manufacturer of permanent all-wheel-drive vehicles worldwide, a claim from its own quattro page, not an independent ranking. The practical difference between brands comes down to the same design choices covered above: a mechanical centre differential, a clutch that engages on demand, or separate electric motors. For the difference between all-wheel drive and traditional four-wheel drive, our AWD vs 4WD explainer is the place to start.
We have not included winter-driving or tyre advice here because no Audi page we read makes safety claims we could pass on; for cold-weather questions, follow your owner’s manual and tyre maker guidance.
Frequently Asked Questions
What does quattro mean on Audi cars?
Quattro is Audi’s name for its permanent all-wheel-drive technology, first shown in the original quattro coupe at the 1980 Geneva Motor Show. The word is commonly said to be Italian for four, referring to four driven wheels. It names a family of systems rather than one part, from a mechanical centre differential to clutch-based and electric versions.
Does every Audi have quattro?
No. EPA listings show front-wheel-drive and rear-wheel-drive Audis, such as the 2024 A3 (front-wheel drive) and the 2025 Q4 45 e-tron and Q6 e-tron (rear-wheel drive). Some all-wheel-drive Audis, like the 2024 RS 3, do not have quattro in the EPA model name. Check the drive field on fueleconomy.gov or the owner’s manual for a specific car.
Is quattro always sending power to all four wheels?
Not on every system. Audi describes quattro as permanent all-wheel drive, but quattro with ultra can disconnect the rear drivetrain and run as front-wheel drive at low load, then re-engage in about 200 milliseconds when all-wheel drive is needed. Torsen and crown-gear systems keep both axles connected through a centre differential.
Does quattro use more fuel than front-wheel drive?
Usually somewhat. For the 2024 Audi A3, EPA lists 32 mpg combined for the front-wheel-drive car and 30 mpg for the quattro, or $2,100 versus $2,250 in estimated annual fuel cost. Audi says quattro with ultra used on average 0.3 litres per 100 km less than conventional all-wheel drive in its own tests.
Can electric Audis have quattro?
Yes. Audi uses the quattro name for electric all-wheel drive on models such as the Q4 Sportback e-tron, Q8 Sportback e-tron and RS e-tron GT. Audi says the RS e-tron GT redistributes torque about five times faster than a mechanical quattro. EPA also lists rear-wheel-drive Q4 and Q6 e-tron versions without it.
Conclusion
Quattro means Audi’s permanent all-wheel drive, but the name covers several different layouts built over more than four decades, and not every Audi has one. The most useful habit is to identify which system a specific car uses and check its drive type rather than trusting a badge or a model name. Use the tables above as a reference, and verify any specific model with fueleconomy.gov or its owner’s manual.
