2027 Audi RS 5 vs RS 3 Competition Limited: Which One Would You Buy?

Audi has two very different performance sedans heading into 2027, and they represent two completely different philosophies. On one side is the all-new Audi RS 5 Sedan, a powerful plug-in hybrid that embraces the future. On the other is the Audi RS 3 Competition Limited, a special edition that celebrates one of the most beloved engines in Audi history. While both carry the RS badge, they are aimed at different types of enthusiasts.

The new RS 5 Sedan is the most technologically advanced performance sedan Audi has ever built. Under the hood is a twin turbocharged 2.9 liter V6 paired with an electric motor, producing a combined 630 horsepower. That makes it significantly more powerful than the outgoing model and gives it acceleration that rivals many exotic sports cars. Audi has also focused heavily on chassis technology, introducing advanced torque vectoring and a more dynamic rear differential that allows the car to feel more agile than previous RS models.

What makes the RS 5 especially interesting is its dual personality. It can deliver impressive electric driving capability for daily commuting while still offering serious performance when the road opens up. This combination allows Audi to meet stricter emissions standards while giving drivers even more power than before. It is a clear look at where Audi Sport is heading in the future.

The RS 3 Competition Limited takes a very different approach. Instead of focusing on electrification, it celebrates Audi’s legendary 2.5 liter turbocharged 5 cylinder engine. Producing 394 horsepower, it may not match the raw output of the RS 5, but numbers only tell part of the story. The unique sound of the 5 cylinder engine has become one of Audi’s trademarks, and many enthusiasts consider it one of the best sounding engines currently available.

Limited to only 750 units worldwide, the RS 3 Competition Limited adds exclusivity to the formula. It receives adjustable coilover suspension, lightweight components, ceramic brakes, special wheels, and unique styling details that separate it from the standard RS 3. The result is a more focused driver’s car designed for enthusiasts who appreciate mechanical engagement and rarity.

When comparing performance, the RS 5 clearly has the advantage on paper. With 630 horsepower and a sophisticated hybrid system, it accelerates harder and offers greater overall capability. However, the RS 3 Competition Limited delivers something that cannot easily be measured by statistics. Its smaller size, lighter weight, and iconic engine create a more emotional driving experience that many enthusiasts still prefer.

Inside, the RS 5 showcases Audi’s latest technology with larger displays, more advanced software, and a highly digital cabin. The RS 3 Competition Limited remains more traditional, placing greater emphasis on the driving experience rather than cutting edge technology.

The biggest difference between these two cars may be what they represent. The RS 5 is Audi’s vision of the future, combining electrification with extreme performance. The RS 3 Competition Limited is a celebration of Audi’s past and present, preserving the character that made the brand’s performance cars famous around the world.

For buyers looking for the fastest and most advanced Audi sport sedan, the RS 5 will likely be the clear choice. For enthusiasts who value engine character, exclusivity, and a more traditional driving experience, the RS 3 Competition Limited could become one of the most desirable modern Audi models ever produced.

In many ways, these two cars tell the story of where the automotive industry stands today. One looks forward, while the other honors a legendary formula that enthusiasts hope never disappears.
