5 reasons to buy the 2018 Audi S8

1. Plenty of standard features 

There’s only one version of the 2018 Audi S8 trim, 'Plus', so Audi packs in a comprehensive list of features. For example, an eight-inch high-resolution screen, a trackpad for handwritten input, Bluetooth® connectivity, and a heads-up display are part of the included technology. Or, if comfort features are more your style, indulge in four-zone automatic climate control, heated and ventilated front seats, massage functionality, a panoramic sunroof, and soft-close power doors. 

2. Available suite of driver assists 

Elevate your highway commute by looking for a 2018 Audi S8 with the Executive Plus package, which blends innovative technology with even more comfort touches. As for active driver aids, the Executive Plus package adds lane departure warning, adaptive cruise control, and forward collision mitigation. Or, look for a 2018 Audi S8 with the available night-vision camera system, which identifies pedestrians and animals that hide in the dark. 

3. Adrenaline pumping performance 

Get the heart-pounding driving experience you thought only a sports car could deliver in the 2018 Audi S8. That’s because the turbocharged V8 engine makes 605 hp, and the snappy eight-speed transmission delivers a zero-to-60 mph time of just 3.7 seconds. Plus, the standard quattro® AWD intelligently uses torque vectoring to shift power to the wheels with the best traction. At the same time, the adaptive suspension dampens body roll, delivering deceptively sharp handling for a sedan this size. 

4. A refined interior experience 

There’s an interesting juxtaposition to the experience a 2018 Audi S8 delivers, which is both aggressive and exceptionally luxurious. For example, the same air suspension detects any road defects and adjusts dampening so you barely feel a thing. Plus, high-end materials and solid build isolate almost all exterior noises. That means the 2018 Audi S8 has the sophisticated ride you expect from a flagship luxury sedan. 

5. Immersive audio systems 

From classical to classic rock, the 2018 Audi S8 gives you a front-row audio experience. High-end sound systems such as the standard 14-speaker Bose® system immerse you in the music. Or, look for a 2018 Audi S8 with the upgraded Bang & Olufsen® audio system, which surrounds you with 19 speakers and 1,400 watts of high-fidelity sound.
