The differences between Audi S4 and Audi A4 lie in their body dimensions: the Audi S4 measures 4749mm in length, 1842mm in width, and 1400mm in height, with a wheelbase of 2831mm; the Audi A4 measures 4750mm in length, 1842mm in width, and 1433mm in height, with a wheelbase of 2828mm. In terms of configuration, the Audi S4 is equipped with the quattro permanent all-wheel drive system, a four-link front suspension, leather seats with 10-way electric adjustment and lumbar support, a three-spoke leather-wrapped sports steering wheel, an automatic climate control system with sunlight sensor, a trip computer with driving information display, and Sideguard head airbags.

The differences between the Audi S4 and Audi A4 are quite noticeable. Having driven Audi cars for a while, the S4 focuses on performance, delivering stronger power, a more intense acceleration feel, and a significant push-back sensation, thanks to its V6 turbocharged engine. In contrast, the A4 uses a standard four-cylinder engine, offering smooth starts and better fuel efficiency, making it ideal for daily commutes. Exterior-wise, the S4 features a more aggressive front grille, larger wheels, and dual exhaust pipes, giving it a sporty appearance, while the A4 is more understated with sleek lines. Inside, the S4 adds sport seats and carbon fiber accents, but comfort levels are similar. The S4 is significantly more expensive, with higher maintenance costs. If you don’t plan on racing, the A4 is sufficient and offers better value for money. Don’t overlook the suspension tuning—the S4 is stiffer for better handling, providing stability in corners but a bumpier ride, while the A4 is softer and more comfortable.

I'm a car modification enthusiast, and the differences between the Audi S4 and A4 are quite striking in terms of power and potential. The S4's V6 engine comes with high horsepower straight from the factory, and a simple ECU tune or adding a supercharger can squeeze out even more performance. On the other hand, the A4's four-cylinder engine is harder to modify and prone to issues when tinkered with. In terms of chassis, the S4 comes with sport suspension and reinforced brakes, offering better control on mountain roads or tracks, while the A4's standard suspension is softer with noticeable body roll in corners. Exterior-wise, the S4 has a more aggressive kit, like wider wheel arches and quad exhausts, while the A4 is simpler and more family-oriented. Maintenance for the S4 is pricier, but it offers more fun for mods, like the thrilling exhaust roar. If you're on a tight budget, the A4 is fuel-efficient and practical, but I'd highly recommend the S4 to car-loving buddies.

The Audi A4 is suitable for those who pursue comfort and refinement, while the S4 leans towards a sportier style on top of luxury. The A4 features softer seats and excellent sound insulation, making long drives less tiring. The S4 adds Alcantara sport seats, which are firmer but offer better support, along with racing-inspired stitching in the interior—though the overall sense of luxury is similar between the two. Externally, the A4 is understated and elegant, while the S4 has a more aggressive front fascia and larger wheels, which may slightly compromise quietness. The engines differ significantly: the S4 accelerates faster, but its V6 engine is slightly noisier, whereas the A4 is quiet, smooth, and hassle-free. The S4 is notably more expensive and has higher fuel consumption. For most families, the A4 offers better value—unless you're truly captivated by that exhilarating acceleration.

From a financial perspective, choosing between the Audi A4 and S4 depends on your budget. The A4 is significantly more affordable, offering fuel efficiency and reliability for daily commutes, along with lower maintenance costs. The S4, while more powerful, comes with a much higher price tag, increased insurance premiums, and greater fuel consumption, though its exhilarating acceleration during highway overtaking is a definite plus. Exterior-wise, the S4's sporty kit looks aggressive but offers limited practical value, whereas the A4's classic design is more than sufficient. In terms of driving, the S4 accelerates faster by a few seconds, but in city traffic, the difference is negligible. Considering resale value, the A4 generally sells better, while the S4 caters to a niche market. In my opinion, if you're just looking for a daily driver, the A4 is the smarter choice—the money saved can be used for additional features. Performance enthusiasts, however, might think differently.
