The automotive landscape is constantly evolving, with manufacturers making bold moves to redefine their vehicle lineups. For instance, Audi made a significant decision with its 2025 models, discontinuing the popular A4 and S4 names and instead placing the future of its compact sports sedan segment squarely on the shoulders of the A5 and S5. This strategic shift streamlines their offerings, emphasizing the versatility and appeal of the Sportback body style, which, as you may have seen in the accompanying video, no longer even carries the ‘Sportback’ suffix in its name.
This latest iteration, particularly the 2025 Audi S5, is engineered to strike a remarkable balance between exhilarating performance and sophisticated luxury. Equipped with a potent turbocharged V6 engine and Audi’s renowned quattro all-wheel drive system as standard, it aims to carry forward a rich legacy. Let’s delve deeper into what makes the all-new S5 a standout in its class, exploring its power, design, technology, and practical everyday usability.
Unpacking the 2025 Audi S5’s Performance Prowess
The heart of the 2025 Audi S5 is its longitudinally mounted 3.0-liter turbocharged V6 engine, a significant upgrade over the A5’s four-cylinder unit. This powerplant delivers an impressive 362 horsepower and 406 pound-feet of torque, representing nearly 100 more horsepower and over 100 more foot-pounds of torque compared to the A5. Even against its predecessor, the new S5 boasts a power bump, surpassing the previous generation’s 349 horsepower and 369 pound-feet of torque.
Power is channeled through a new 7-speed dual-clutch transmission, replacing the earlier 8-speed ZF automatic. This dual-clutch system is designed to enhance performance, providing quicker shifts and a more engaging driving experience. While it loses the 48-volt mild-hybrid system found in other markets (reportedly due to U.S. customer preference, or perhaps cost-cutting), the raw power delivery remains undeniable.
Audi claims a 0-60 mph time of 4.3 seconds, but real-world testing in the video demonstrated an even more blistering 4.03 seconds with launch control. This makes the 2025 Audi S5 remarkably quick, roughly 0.3 seconds faster than the previous S5 and a full 1.5 seconds quicker than the A5. Without launch control, the S5 still achieves a rapid 4.5 seconds to 60 mph, ensuring impressive acceleration in any scenario. The top speed is electronically limited to 155 mph, while the vehicle weighs in at just under 4,300 pounds, about 300 pounds heavier than its A5 sibling.
Design and Dimensions of the 2025 Audi S5 Sportback
The 2025 Audi S5 is an aesthetically pleasing machine, showcased in the video in a sophisticated Magnet Gray. This color, while debated by the reviewer, highlights the S5’s refined yet sporty lines, especially with the Edition One package. The vehicle is built on Audi’s new Premium Platform Combustion (PPC) architecture, signaling it as one of the company’s last brand-new internal combustion designs before a full pivot to electric vehicles.
Up front, the S5 features full matrix design LED headlights with eight interchangeable daytime running light signatures, allowing for personalization. The distinctive Audi single-frame grille now boasts a unique texture with bronze-copper accents, differentiating it from the A5. Moving along the side, the new S5 is notably larger than its predecessor, riding on a 114-inch wheelbase (2.5 inches longer) and an overall length of 190.4 inches (also 2.5 inches longer). It stands 1.5 inches taller and 0.5 inches wider, lending it a more substantial presence akin to an A6.
The Edition One package adds unique 20-inch alloy wheels with a matte neodymium finish, reminiscent of Porsche’s design philosophy. Stopping power is provided by upgraded brakes, measuring 14.2 inches at the front and 13.8 inches at the rear—over an inch larger than the A5’s setup—complemented by striking red S-logo calipers. The exterior is further enhanced by black painted side mirrors and trim (part of the Edition One and Black Optics packages), and flush-mounted door handles for improved aerodynamics. At the rear, OLED taillights offer eight linked light signatures, a tasteful rear lip spoiler, and the signature quad-outlet exhaust tips, which are also blacked out for a sporty look.
Inside the 2025 S5: Technology and Comfort
Stepping inside the 2025 Audi S5 Prestige reveals an interior that marries cutting-edge technology with luxurious comfort. The featured test car showcases a striking RS Red premium Nappa leather interior with diamond quilting and contrast stitching on the Audi Sport seats. These front seats offer 10 or 12-way power adjustability, along with heating, cooling, and a massaging function—a rare find in this segment. Audi also offers black, and a forthcoming gray and blue two-tone interior, expanding color choices for buyers.
The cabin is dominated by Audi’s “digital stage cockpit,” featuring an 11.9-inch digital instrument cluster and a large 14.5-inch center MMI display. The MMI system runs Audi’s latest software, offering wireless Apple CarPlay and Android Auto, built-in YouTube, a racing game, Alexa, and Google integration. While some traditionalists might miss the ability to display GPS directly in the driver’s cluster, navigation can be viewed on the central MMI or an innovative passenger display, which can also stream YouTube. An augmented reality head-up display provides essential information, including turn-by-turn navigation.
Practicality is also a strong suit for the 2025 Audi S5. Rear passengers benefit from approximately 36 inches of legroom, which Audi claims is best-in-class, offering 1-2 inches more than rivals. The rear seats also feature three-level heating and can fold down to create a nearly flat load floor, expanding cargo space from 22.6 cubic feet to an impressive 33.8 cubic feet—rivaling some SUVs. Other thoughtful touches include a 15-watt vented wireless phone charging pad, dual USB-C ports, a 12-volt outlet, and a dimmable panoramic sunroof with six adjustable frosted segments, allowing occupants to control light and privacy.
Driving Dynamics and Daily Liveability of the 2025 Audi S5
The 2025 Audi S5 truly shines in its driving dynamics, offering a versatile “dual personality” that transitions seamlessly from comfortable daily cruiser to an engaging sports sedan. The vehicle comes standard with progressive sport steering and, in the Prestige package, adaptive dampers. This setup allows for a responsive and quick steering feel, while the adaptive suspension maintains a compliant ride for everyday commuting and highway cruising. When pushed, the body exhibits minimal lean, maintaining composure through turns.
Engaging Dynamic mode elevates the driving experience. The revs climb, the exhaust valves open, and the V6 engine produces an authentic, sonorous wail, complete with pleasing pops and crackles that were noticeably absent in the A5. The new 7-speed dual-clutch transmission delivers sharp, responsive shifts, especially when using the paddle shifters. Audi’s quattro all-wheel drive system, paired with a sport differential, intelligently sends power to the outside rear wheel, mimicking a rear-wheel-drive feel and enhancing cornering agility, similar to Acura’s Super Handling All-Wheel Drive system.
Despite its performance capabilities, the 2025 Audi S5 remains a highly livable car. The cabin is refined and quiet, with no discernible squeaks or rattles, even over varied road surfaces. While fuel efficiency is slightly down compared to the previous generation due to the removal of the mild-hybrid system for the U.S. market, it still achieves an estimated 19 MPG city, 28 MPG highway, and 22 MPG combined. Real-world testing showed an average of 23 MPG in mixed driving, with highway cruising yielding around 27 MPG, providing a practical real-world range of approximately 350 miles on a full tank of premium fuel.
Market Positioning and Value Proposition of the 2025 Audi S5
The 2025 Audi S5 is not just about performance and luxury; it’s also positioned competitively within its segment, offering significant value. Audi’s sales figures in North America have faced challenges in recent years compared to rivals like BMW and Mercedes, making new models like the S5 crucial to their resurgence. Starting at approximately $62,700, the S5 undercuts its primary German competitors. For example, a BMW M440i Gran Coupe with xDrive typically starts around $66,000, placing the Audi S5 at a more accessible price point for similar performance and features.
While some competitors, like the Lexus IS500 (starting around $60,000 for a rear-wheel-drive, naturally aspirated V8), offer different driving dynamics, the 2025 Audi S5 Sportback stands out for its all-wheel-drive capability, modern infotainment, and superior practicality. Its increased interior and cargo space, impressive technology suite, and robust performance make it a compelling choice for buyers seeking a compact luxury sports sedan that offers a well-rounded and engaging daily driving experience without breaking the bank.
