2018-2020 Audi S3 Sedan (8V facelift ) 2.0 TFSI (300 Hp) quattro S tronic

Technical Specifications

The Audi S3 Sedan (8V, facelift) 2.0 TFSI 300 Hp quattro S tronic is a high-performance variant of the Audi A3 Sedan. Introduced as part of the 8V generation’s facelift in 2016, production of this specific configuration ran from 2018 to 2020. It served as Audi’s entry point into the world of high-performance sedans, offering a compelling alternative to rivals like the BMW M235i/M240i and Mercedes-AMG CLA 35. The “quattro” designation signifies Audi’s renowned all-wheel-drive system, while “S tronic” denotes the seven-speed dual-clutch transmission. This combination aimed to deliver rapid acceleration, precise handling, and a refined driving experience.

Powertrain & Engine Architecture

At the heart of the S3 Sedan is the EA888 2.0-liter turbocharged four-cylinder engine, specifically the DNUE engine code. This engine is a direct-injection unit, utilizing a sophisticated fuel injection system to maximize efficiency and power output. The DNUE features an integrated exhaust manifold for improved turbocharger response and thermal management. The turbocharger itself is a twin-scroll unit, further enhancing responsiveness. The engine also incorporates variable valve timing on both the intake and exhaust sides, optimizing performance across the rev range. The S tronic seven-speed dual-clutch transmission provides incredibly fast and smooth gear changes, contributing significantly to the car’s acceleration capabilities. This transmission allows for both automatic operation and manual gear selection via steering wheel-mounted paddles. The dual-clutch design allows for pre-selection of the next gear, resulting in near-instantaneous shifts and minimizing torque interruption.

Driving Characteristics

The 300 horsepower and 295 lb-ft of torque, coupled with the quattro all-wheel-drive system, result in exhilarating performance. The S3 Sedan can accelerate from 0 to 60 mph in approximately 4.5 seconds. The S tronic transmission’s quick shifts and the quattro system’s ability to distribute power effectively provide excellent traction, even in challenging conditions. Compared to lower-powered A3 variants, the S3 offers a significantly more engaging driving experience. While the manual transmission offered in some markets provided a more raw connection, the S tronic delivers a level of convenience and speed that appeals to many drivers. The gear ratios are tuned for acceleration, with shorter ratios in the lower gears and a taller final drive for highway cruising. The quattro system intelligently manages power distribution between the front and rear axles, optimizing grip and stability in various driving scenarios. The car feels planted and confident, even when pushed hard through corners.

Equipment & Trim Levels

The S3 Sedan came well-equipped as standard. Key features included sport seats upholstered in a combination of leather and Alcantara, a flat-bottomed steering wheel, and aluminum interior trim. The infotainment system featured a 7-inch display screen with Audi’s MMI interface. Standard safety features included Audi’s side assist, rear cross-traffic alert, and a rearview camera. Optional extras included a larger 8-inch infotainment screen with navigation, a Bang & Olufsen sound system, and a panoramic sunroof. The S3 also offered a range of exterior customization options, including different wheel designs and paint colors. The interior design emphasized a sporty yet sophisticated aesthetic, with attention paid to detail and material quality.

Chassis & Braking

The S3 Sedan’s chassis is specifically tuned for performance. It features a sport-tuned suspension with stiffer springs and dampers compared to the standard A3. The front suspension utilizes the McPherson strut design, while the rear suspension employs a multi-link setup. This configuration provides a good balance between ride comfort and handling precision. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. The electronic stability control (ESC) system is calibrated to allow for a degree of wheel slip in Sport mode, enhancing driving enjoyment. The larger brake rotors and upgraded calipers contribute to improved stopping performance and fade resistance.

Market Reception & Comparison

The Audi S3 Sedan was generally well-received by automotive critics. It was praised for its potent performance, refined interior, and advanced technology. Compared to other trims in the A3 lineup, the S3 offered a substantial performance upgrade, justifying its higher price tag. Fuel economy was respectable for a performance sedan, averaging around 34 mpg in combined driving. Reliability was generally good, although some owners reported minor issues with the infotainment system. Compared to rivals like the BMW M235i/M240i, the S3 offered a more understated and sophisticated driving experience, while the Mercedes-AMG CLA 35 focused more on styling and luxury. The S3 struck a balance between performance and practicality, making it an appealing option for buyers seeking a versatile high-performance sedan.

Legacy

The 2.0 TFSI engine and S tronic transmission combination in the S3 Sedan have proven to be relatively reliable over the long term. The EA888 engine is known for its durability, and the S tronic transmission, while requiring more frequent maintenance than a traditional automatic, is generally robust when properly serviced. Today, the 8V S3 Sedan remains a popular choice in the used car market, offering a compelling blend of performance, luxury, and practicality. Its reputation for reliability and its engaging driving dynamics continue to attract enthusiasts seeking a high-performance sedan at a reasonable price point. Proper maintenance, including regular oil changes and transmission servicing, is crucial for ensuring the longevity of this powertrain. The S3’s enduring appeal is a testament to its well-rounded design and its ability to deliver a rewarding driving experience.
