The differences between the S4 and S5 are: 1. Different dimensions: The S4 measures 4770mm in length, 1847mm in width, and 1404mm in height; the S5 measures 4702mm in length, 1846mm in width, and 1331mm in height. 2. Different body structures: The S4 has a 4-door, 5-seat sedan body structure; the S5 has a 2-door, 4-seat hardtop coupe body structure. Taking the 2020 S4 3.0TFSI and the Audi 2020 S5 3.0T Coupe as examples: Both cars are manufactured by Audi (imported), classified as mid-size cars, with gasoline as the energy type, a maximum power of 260kw, a maximum torque of 500nm, an 8-speed automatic manual transmission, and a top speed of 250 kilometers per hour.

To discuss the differences between the S4 and S5, as someone who frequently drives both, the key lies in the driving experience. The S4 is a four-door sedan with a more balanced chassis tuning, offering stable high-speed cruising and less aggressive cornering, making it ideal for long trips. The S5, with its coupe design, delivers a more dynamic drive—its lower body enhances agility in turns. Both share the same 3.0T V6 engine, but the S5 might have a slightly quicker acceleration response by 0.1 second, and its manual shifts in Sport mode feel crisper. In city driving, the S5’s louder exhaust note adds excitement, while the S4 offers better sound insulation, making Comfort mode less fatiguing over time. On highways, the S5’s lower drag gives a more planted feel, though both average around 10L/100km in urban areas. The S4’s lighter weight grants marginally nimbler starts. For pure driving thrill, the S5 stands out, but the S4 is the more practical daily choice.

As a dad with kids, I've deeply experienced driving both the S4 and S5, with the main differences lying in practicality. The S4 sedan offers a spacious rear seat, providing ample legroom for children without feeling cramped, and its trunk easily accommodates a stroller. In contrast, the S5 coupe or Sportback versions are less convenient for rear-seat access, with limited space that barely fits luggage. In terms of interior, the S5's firmer seats result in a bumpier ride on long trips compared to the S4's more comfortable, softer seating. Price-wise, the S5 costs tens of thousands more, with slightly higher and maintenance fees. Fuel consumption and performance are similar, but the S4 is more economical and hassle-free for daily commutes. While the S5 Sportback can balance family use with sportiness, the S4 proves to be the more practical and cost-effective choice—saving money is what truly matters.

In the eyes of aesthetics enthusiasts, the difference between the S4 and S5 is significant: the S5's sleek fastback lines are sexy and eye-catching, turning heads on the street, with more carbon fiber details in the interior and dazzling light strips; the S4 has a stable and low-key business style with soft and enduring lighting. Whether the higher price of the S5 is worth paying for its beauty depends on one's love for bold designs.

The budget shows that the S4 starts at over 500,000, while the S5 is about 30,000 to 50,000 more expensive. costs are similar as they share the same engine, but the S5 has slightly higher insurance premiums and better resale value, making it more popular in the used car market. Fuel consumption is the same. Buying an S4 is more cost-effective, putting money where it counts.

From a technical perspective, both vehicles share the same 3.0T V6 engine and quattro all-wheel drive system. However, the S5 features stiffer suspension tuning for more aggressive handling. The S4 is lighter, offering slightly quicker acceleration off the line. The dynamic balance system has been fine-tuned to make the S5 more stable at high speeds.
