The 2017 Audi A8 stands as a benchmark in the executive car segment, combining sophisticated design, plush ride quality, and forward-thinking technology. This flagship sedan excels in delivering a serene driving experience while offering engaging dynamics, making it a compelling choice for those prioritizing refinement over outright sportiness.
Design and Exterior Highlights
Audi’s 2017 A8 features a sleek, understated aesthetic that emphasizes elegance rather than bold aggression. Its aluminum spaceframe construction keeps weight down, contributing to both efficiency and agility. The front grille, a signature Audi element, dominates the fascia, flanked by sharp LED matrix headlights that provide superior nighttime visibility.
- Body Styles: Available primarily as the long-wheelbase A8 L, offering extended rear legroom for chauffeured comfort.
- Wheel Options: Up to 21-inch alloys in Sport packages enhance stance and grip.
- Aerodynamics: Optimized for low drag, aiding fuel economy on long journeys.
The overall length exceeds 5.2 meters in LWB form, yet clever proportions make it less intimidating than rivals like the Mercedes S-Class. Subtle character lines and flush door handles underscore its premium build quality.
Powertrains and Performance
Under the hood, the A8 lineup caters to diverse preferences with potent yet efficient engines, all paired to an 8-speed Tiptronic automatic and standard quattro all-wheel drive.
| Engine | Power | 0-60mph | Fuel Economy (mpg) |
|---|---|---|---|
| 3.0L V6 TFSI | 333 hp | 5.4s | ~30 combined |
| 4.0L V8 TFSI (Sport) | 420 hp | 4.5s | ~25 combined |
| 3.0L V6 TDI Diesel | 258 hp | 5.6s | ~40-45 |
The V6 diesel shines for UK buyers, balancing torque (up to 443 lb-ft) with respectable economy, ideal for high-mileage motorway runs. Petrol variants deliver effortless acceleration, with the V8 providing supercar-like thrust without sacrificing composure.
Quattro’s grip transforms the A8’s handling; wide tires and precise hydraulic steering (in earlier models) inspire confidence on twisty roads. Despite its size, it corners flat, thanks to optional dynamic all-wheel steering that angles rear wheels for better maneuverability.
Chassis Dynamics and Ride Quality
The adaptive air suspension is a highlight, automatically adjusting height and damping for optimal comfort or sportiness. Predictive systems scan ahead via cameras, preempting bumps for a glass-smooth ride. Double glazing minimizes noise, creating a vault-like cabin even at highway speeds.
In town, rear-wheel steering shrinks the turning circle, making parking straightforward. On undulating B-roads, the A8 remains planted, though it prioritizes poise over the razor-sharp responses of sportier saloons. Safety features like pre-sense side impact protection raise the body during collisions, channeling forces to the reinforced underfloor.
Interior Refinement and Space
Step inside, and the A8’s cabin exudes quality with supple leather, real wood veneers, and ambient lighting. The 12.3-inch Virtual Cockpit digital gauge cluster redefines instrumentation, displaying navigation or media in crisp detail. Front seats offer massage, ventilation, and extensive adjustment; rear Relaxation seats in A8 L models include footrests for ultimate lounging.
- Seating: Generous space for four adults; A8 L adds limo-like rear legroom.
- Storage: 14.2 cu ft trunk is adequate but trails rivals.
- Build: Flawless fit-and-finish rivals Bentley levels.
Head-up display projects key info onto the windshield, enhancing focus. Visibility is excellent, with standard parking sensors and optional 360-degree cameras simplifying maneuvers.
Technology and Infotainment
Audi’s MMI system, with dual touchscreens and haptic feedback, controls most functions. While intuitive, the nested menus can distract during motion—voice commands help mitigate this. Standard kit includes sat-nav, Bluetooth, and LED lights; options like active cruise control and lane-keeping add semi-autonomous capability up to 37mph on compatible roads.
Limitations persist: UK regulations curb full hands-free driving, requiring wheel contact. Still, traffic jam assist eases urban crawl. Bang & Olufsen audio elevates entertainment, and onboard TV (where legal) offers passenger diversion.
Safety and Driver Assistance
The A8 earned top Euro NCAP scores, bolstered by pre-sense front and side detection. Night vision, intersection assist, and automatic emergency braking form a comprehensive suite. Quattro and stability systems ensure control in adverse conditions.
Rivals Comparison
| Model | Strengths | A8 Edge |
|---|---|---|
| Mercedes S-Class | Ultimate opulence, air ride | Better handling, lighter weight |
| BMW 7 Series | Agile chassis, tech | Superior quietness, Virtual Cockpit |
| Jaguar XJ | Style, value | Tech depth, quattro grip |
The A8 holds its own, blending comfort with engagement better than most.
Ownership Costs and Reliability
Expect premium running costs: diesels fare best at 40+ mpg. Servicing via Audi dealers is pricey, but residuals hold firm. Warranty covers 3 years/60,000 miles. Tech-heavy nature demands diligent maintenance to avoid glitches.
Pros and Cons
- Pros: Exquisite interior, balanced ride/handling, advanced safety tech, powerful quattro system.
- Cons: Infotainment usability, trunk space, higher costs vs. rivals.
