The B5S4 Audi refers to the first generation (B5) Audi S4, which was produced from 1997 to 2002. It is a high-performance sports sedan based on the Audi A4 platform and is best known for its 2.7-liter twin-turbocharged V6 engine. The engine produces around 261 horsepower and 295 lb-ft of torque, enabling the car to accelerate from 0 to 100 km/h (62 mph) in about 5.7 seconds, with an electronically limited top speed of 250 km/h (155 mph). It features Audi’s quattro all-wheel-drive system, a six-speed manual or a five-speed automatic transmission, and comes equipped with upgraded suspension, brakes, and sporty interior and exterior styling compared to the base A4 model. The B5S4 is valued among enthusiasts for its strong performance, handling, and tuning potential.
The Audi B5 S4 differs significantly from other S4 generations in engine type, performance, technology, and design features. The B5 S4 (1997–2002) uses a 2.7-liter twin-turbo V6 engine with all-wheel drive and is prized for its strong tuning potential. Later generations, such as the B6 and B7 S4, shifted to a naturally aspirated 4.2-liter V8 engine for more linear power delivery but at the cost of added weight. The B8 S4 switched to a supercharged 3.0-liter V6 for a balance of power and improved efficiency, while the B9 S4 adopted a turbocharged 3.0-liter V6 and an updated, more luxurious interior.
Key differences include:
Engine: B5 has a twin-turbo V6; B6/B7 have a naturally aspirated V8; B8 is supercharged V6; B9 is turbocharged V6.
Transmission: B5 comes with a 6-speed manual or a 5-speed automatic. Newer models offer dual-clutch or advanced automatics.
Power: While the B5 S4 has about 261 hp, later models increased power output, with B7 at 339 hp, B8/B9 exceeding 330–350 hp.
Performance: Each generation improves 0–100 km/h acceleration.
Technology: Newer models have advanced suspension, safety, infotainment, and driving-assistance systems.
Styling: Each update brings more modern aesthetics, with changes in grilles, lighting, interior features, and luxury touches.
The B5 S4 remains highly regarded for its robust engine and modifiability, while newer S4 generations focus increasingly on refinement, luxury, and usable daily-driver performance.
