Why it stands out
The 2018 Audi S4 continues the legacy of delivering a high-performance experience wrapped in a luxurious package. One of its most significant traits is the standard Quattro all-wheel drive, which enhances its stability and grip, especially in challenging conditions. The sporty sedan comes equipped with a robust 3.0-liter V6 engine generating an impressive 354 horsepower, allowing it to accelerate from 0 to 60 mph in just 4.4 seconds. With its eight-speed automatic transmission and sport-tuned suspension, the S4 strikes a balance between thrilling performance and everyday drivability.
The interior reflects Audi's commitment to quality, featuring a mix of luxury and technology, including the innovative Virtual Cockpit display. While it may not have the same athletic handling as some of its rivals, like the BMW M340i, its smooth ride and well-appointed cabin make it appealing for those seeking both performance and comfort. The S4 also boasts substantial standard features, increasing its value compared to standard A4 models and making it a compelling choice for buyers looking for a premium sports sedan.
