Why it stands out
The 2018 Audi S4 is a performance-oriented luxury sedan that appeals to buyers looking for a blend of sportiness and sophistication. Equipped with a potent 3.0-liter twin-scroll turbocharged V6 engine generating 354 horsepower and 369 lb-ft of torque, this model delivers exhilarating performance with a 0-60 mph time of just 4.4 seconds, while maintaining a smooth ride thanks to standard all-wheel drive. The car has a reputation for high-quality interiors adorned with luxurious materials and advanced technology, making it a comfortable and stylish option for daily driving or spirited weekend outings. However, prospective buyers should be aware that lower trims may lack some desirable features like adaptive cruise control, which became standard in later model years, and the maintenance costs associated with Audis might be higher compared to some rivals.
