The enhanced power of the new Audi S5 Avant, rated at 270 kW / 367 PS, might not seem very impressive at first. However, with the introduction of a mild-hybrid system, this performance-oriented estate achieves lower fuel consumption and improved acceleration.
Sporting a robust and muscular frame, the new Audi S5 Avant could easily be mistaken for the Audi RS6 at first glance. So, how does it differ? Let’s clarify the naming strategy: moving forward, electric models will use even numbers for their designations, while combustion engine vehicles will use odd numbers. This means the A5 is now positioned above the previous A4 model, effectively merging two classes into one. Furthermore, Audi is gearing up to reclaim its competitive edge against its rivals in Munich, aiming for a bolder design approach exemplified by the striking S5 Avant. This new model certainly captivates, and we eagerly anticipate the reveal of the RS5 Avant, hoping Audi maintains an appropriate balance with its striking aesthetics.
We will have to wait to see how the RS5 Avant turns out. For now, our attention turns to the powerful S5 Avant. Its 3.0-litre V6 TFSI engine produces a solid 270 kW / 367 PS along with a maximum torque of 550 Nm. While this represents a minor enhancement of 10 kW / 13 PS over the current petrol variant in the A5 range, it still marks an improvement worth noting. Let’s explore the technology behind this model.
The Audi S5 Avant is now built on the new Premium Platform Combustion (PPC) rather than the Modular Longitudinal Platform (MLB evo). Despite the rise of electric mobility, there remains a dedicated platform for combustion engines, which incorporates some electrification. The 3.0-litre six-cylinder engine features a 48-volt mild-hybrid system (mhev plus). This setup includes a belt-starter generator (BSG) along with a driveline generator (DLG) located on the transmission output shaft, providing an additional power boost of up to 18 kW / 24 PS and 230 Nm of torque.
In addition, the vehicle can recover energy with a maximum capacity of 25 kW, enabling it to come to a complete stop if required. The DLG disengages at speeds over 140 km/h. This sophisticated system relies on a battery that can quickly absorb and release energy. The 48V lithium iron phosphate battery offers a capacity of 1.8 kWh, facilitating brief electric drives. Beyond enhancing drivability, this E-module can reduce petrol consumption by as much as 0.74 l/100 km. According to Audi, the S5 Avant achieves a consumption rate of 7.6 litres per 100 km.
Ultimately, the driving experience of the S5 is what truly matters. After all, few purchase a €80,150 estate solely for its fuel efficiency ratings. Enjoyment on the road is key, and the S5 certainly delivers on that front—providing a lively ride without overwhelming the driver. It’s a sophisticated athlete, quick and composed at speed, allowing those behind the wheel to feel comfortable regardless of their driving skill level. Significant improvements in steering responsiveness contribute to a more engaging experience compared to earlier models.
With its sport suspension lowered by 20 millimetres, the standard sport differential, paired with brake vectoring technology, allows for rapid response during cornering. This 4.83-metre sports estate excels in handling, supported by improvements in chassis design, including refined control arm bearings and increased front axle camber, which enhance its cornering agility. Typically, the S5 Avant remains stable and predictable during turns. Only when pushed beyond limits do the all-wheel drive and intricate engineering reveal their constraints, leading to a gradual drift towards the edge of the road—a movement that remains manageable and does not catch the driver off-guard.
Inside, the Audi S5 Avant showcases a modern interior outfitted with curved screens, including an 11.9-inch digital cockpit filled with virtual instruments and a 14.5-inch touchscreen that functions as the infotainment hub. The upgraded head-up display is now 85% larger, making navigation prompts easier to spot. Notably, the car features a voice assistant accessible via a steering wheel button or simply by saying “Hey Audi,” which seamlessly integrates ChatGPT if further assistance is needed. While these tech advancements are impressive, the S5 Avant’s true highlight remains its nimbleness on the road.
