Brief Introduction of Audi S4

The Audi S4 is the high-performance variant of Audi’s A4 compact executive car, skillfully blending luxury with exhilarating power. Available primarily as a sedan and an Avant (station wagon), the S4 has carved a niche for itself among enthusiasts who desire a potent daily driver with the practicality for everyday use. Its popularity stems from its sophisticated combination of a powerful engine, Audi’s renowned quattro all-wheel-drive system, and a premium, well-appointed interior. Throughout its multiple generations, the S4 has consistently evolved, offering a range of engines from inline-five and V6 to V8, and back to V6 with modern turbocharging and supercharging technology. This evolution has allowed the S4 to remain a strong competitor in the sports sedan market, appealing to a wide array of driving enthusiasts.

Audi S4 Overview

Generations and History of Audi S4

First Generation (C4; 1991–1994)

The original Audi S4, internally designated as the C4, was introduced in 1991 as a high-performance version of the Audi 100. It was available as both a saloon and an Avant (estate). The C4 S4 was initially powered by a 2.2-liter turbocharged inline five-cylinder engine producing 227 horsepower. A more powerful 4.2-liter V8 engine option was later introduced. This generation laid the groundwork for the S4’s legacy of combining understated looks with impressive performance, further enhanced by the standard quattro all-wheel-drive system. When the Audi 100 was updated and renamed the A6 in 1994, the S4 was accordingly rebranded as the S6.

Second Generation (B5; 1997–2002)

After a brief hiatus, the S4 nameplate returned in 1997, this time based on the smaller A4 platform. The B5 S4 was a significant step forward in performance, featuring a 2.7-liter twin-turbocharged V6 engine that produced 261 horsepower. This engine, combined with a standard six-speed manual transmission and quattro all-wheel drive, made the B5 S4 a formidable competitor in the compact executive sports sedan segment. Available as both a sedan and an Avant, the B5 S4 was praised for its all-weather capability and immense tuning potential. The exterior design was subtly more aggressive than the standard A4, with unique bumpers, side skirts, and larger alloy wheels.

Third Generation (B6; 2003–2005)

The third-generation S4, based on the B6 A4 platform, marked a significant shift in the model’s powertrain philosophy. Launched in 2003, the B6 S4 was equipped with a naturally aspirated 4.2-liter V8 engine, producing 339 horsepower. This made it a direct competitor to other V8-powered rivals. The B6 S4 was available in sedan, Avant, and for the first time, a Cabriolet (convertible) body style. While heavier than its predecessor, the B6 S4 was lauded for its V8 soundtrack and linear power delivery. The design was more muscular than the standard A4, with more pronounced wheel arches and a quad-exit exhaust system.

Fourth Generation (B7; 2005–2008)

The B7 generation S4, introduced in late 2004, was more of an evolution of the B6 rather than a complete redesign. It carried over the 4.2-liter V8 engine with the same power output. The most noticeable changes were cosmetic, with the B7 adopting Audi’s new single-frame grille and revised front and rear styling. Mechanical updates included revised springs and dampers for improved handling. The B7 S4 was also available in sedan, Avant, and Cabriolet variants, continuing to offer a compelling blend of performance and luxury. A special limited edition “25quattro” model was also produced to celebrate 25 years of the quattro system.

Fifth Generation (B8; 2009–2016)

The B8 generation S4, which entered production in late 2008, saw another significant change in engine philosophy. The V8 was replaced by a more efficient and tune-friendly 3.0-liter supercharged V6 TFSI engine, producing 333 horsepower. This move was praised for improving the car’s weight distribution and fuel economy without sacrificing performance. The B8 S4 was available as a sedan and Avant, with the convertible role being taken over by the S5 Cabriolet. A mid-cycle facelift in 2012, known as the B8.5, brought updated styling and technology, including revised headlights and a new MMI infotainment system.

Latest Generation (B9; 2017–Present)

The current B9 generation of the Audi S4 was unveiled in 2015 and features a 3.0-liter turbocharged V6 engine, moving away from the supercharger of the B8. This engine produces 354 horsepower and is paired with an eight-speed Tiptronic automatic transmission. The B9 S4 is available as a sedan and an Avant. A significant interior update was the introduction of the Audi Virtual Cockpit, a fully digital and customizable instrument cluster. A facelift in 2019 (B9.5) brought a more aggressive exterior design, a new MMI touch-screen infotainment system, and for the European market, a switch to a 3.0-liter V6 TDI diesel engine.
