CarGurus Analysis: 2018 Audi S4
Summary
With 131 currently listed for sale and an average price of $23,188.00, 33.6% of 2018 Audi S4s for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2018 Audi S4 4.67 / 5 stars.
82.4% of 2018 Audi S4 models on CarGurus are accident free.
Why it stands out
The 2018 Audi S4 stands out as a performance sedan that blends strong straight-line speed with everyday usability. In this generation, Audi used a 3.0-liter twin-scroll turbocharged V6 producing 354 ponies and 369 pound-feet of torque, paired with an eight-speed automatic and standard all-wheel drive. That combination gives the S4 a zero-to-60-mph time of 4.4 seconds, while still delivering a smooth ride for a performance car. It also brings Audi’s Virtual Cockpit and Google navigation, which help give the cabin a modern, tech-forward feel.
For 2018, the S4’s appeal is also tied to its balance of equipment and refinement. Audi’s standard all-wheel drive and the car’s strong thrust make it feel capable in all conditions, and the interior is described as packing a powerful punch. At the same time, it is not the most athletic handler in its class, and the conservative design may not be as exciting as some shoppers want. Even so, the 2018 S4 remains attractive for buyers who want a quick luxury sedan that is fast, well equipped, and easy to live with.
