Audi has always had a knack for turning odd numbers into magic. Five cylinders, to be precise. From the rally-dominating Sport Quattro to today’s snarling RS3, the company’s turbocharged five-pot has been a mechanical middle finger to conventional engine layouts. Now, 50 years after the engine first appeared, Audi is celebrating the milestone with the RS3 Competition Limited—a £92,885 hot hatch that may also serve as the engine’s swan song.

Yes, that price makes it more expensive than the new RS5, which is the sort of thing that might cause a double take at the dealership. But Audi clearly isn’t trying to move metal here. The Competition Limited is a statement car: a celebration of a half-century of five-cylinder weirdness—and possibly a farewell tour.
The Five-Cylinder Question
Audi CEO Gernot Döllner recently admitted the engine’s future is “still under discussion.” The reason? Euro 7 emissions regulations. The turbocharged 2.5-liter five-cylinder doesn’t currently meet the upcoming standard, and bringing it into compliance would require serious engineering investment.
The problem is scale. This charismatic oddball lives in only two cars: the RS3 and the Cupra Formentor VZ5. That makes the business case tricky.
“I don’t know if we’re able to refinance the investment in EU7 regulations,” Döllner told Autocar. “We will have the discussion at board level.”
Still, he hinted the brand would like to keep it alive, noting the engine gives the RS3 a unique identity among rivals. The Mercedes-AMG A45 relies on a four-cylinder, and the BMW M2 runs a straight-six. Audi’s five-cylinder sits perfectly between them—mechanically unusual and acoustically unmistakable.

If Audi can’t justify the investment, the Competition Limited might end up being the ultimate version of the breed.
Louder, Rawer, More Focused
Under the hood, the headline numbers haven’t changed. The turbocharged 2.5-liter still delivers 394 horsepower and 369 lb-ft of torque, identical to the regular RS3. Audi decided the engine didn’t need more power—it needed more personality.
To that end, the engineers thinned the bulkhead separating the engine bay from the cabin so more induction noise reaches the driver. The exhaust system’s active flaps also open earlier in the rev range, amplifying that unmistakable off-beat five-cylinder soundtrack.
In other words: it’s not faster on paper, but it should feel more alive.
Suspension Nerd Heaven
Where Audi did get serious is the chassis.
The Competition Limited swaps the standard suspension for a set of adjustable coilovers with twin-tube dampers. Up front, those dampers feature remote fluid reservoirs—race-car hardware designed to keep temperatures in check when the car is repeatedly hammered on track.
If that sounds familiar, it should. A similar setup helped make the 2005 Renaultsport Clio 182 Trophy one of the most beloved hot hatches ever built.

Audi also stiffened the rear anti-roll bar and rear springs to sharpen turn-in and reduce body roll. For owners who enjoy fiddling with suspension settings on a Sunday morning, Audi includes a toolkit for adjusting damping.
And there’s plenty to adjust:
- Low-speed bump damping: 12 settings
- High-speed bump damping: 15 settings
- Rebound damping: 16 settings
Front adjustments are accessible from the engine bay, while the rear requires removing the wheels. That might sound like a hassle, but it’s exactly the sort of thing hardcore owners secretly enjoy.
Small Wings, Big Statement
Visually, the Competition Limited leans harder into aggression. The front bumper gets aerodynamic canards and a split chin spoiler, while a new rear wing adds downforce.
The most striking addition, though, is the Malachite Green paint—a deep shade borrowed from the legendary short-wheelbase Sport Quattro. Retro Audi Sport badging and special welcome-light graphics add to the nostalgia.
When you lock or unlock the car, the lights flash in a 1-2-4-5-3 sequence, mimicking the firing order of the five-cylinder engine. It’s the kind of nerdy detail only Audi would think of—and exactly the sort enthusiasts adore.
Inside the Tribute
The cabin continues the celebration.
Deep bucket seats are trimmed in black leather and gold Dinamica microfibre, stitched with contrasting off-white thread. The seatbelts match the stitching, giving the interior a subtle motorsport feel.

The digital instrument cluster switches to white-faced graphics, a nod to the analog dials in the legendary Audi RS2—another icon powered by a five-cylinder.
Rarity Included
Audi will build 750 examples worldwide, split between hatchback and sedan. Only 10 are destined for the UK, all of them hatchbacks.
With a price around £89,000–£92,000 depending on market specification, the Competition Limited sits roughly £26,880 above the standard RS3.
That’s an enormous premium for what is, fundamentally, a compact hot hatch. But then again, this car isn’t really about value.
The Possible End of an Era
If the five-cylinder does disappear, it would mark the end of one of the automotive industry’s most distinctive engines. Few powerplants have such a recognizable soundtrack—or such deep roots in rally history.
The RS3 Competition Limited feels less like a typical special edition and more like a love letter to a mechanical oddity that refused to conform.
And if this truly is the final chapter for Audi’s five-cylinder, it’s going out exactly the way it should: loud, complicated, and just a little bit irrational.
