2016 Audi S8 Plus: 605 Horsepower Super-Sedan Review & Specs

The 2016 Audi S8 Plus represents the pinnacle of Audi’s engineering prowess, transforming the already formidable S8 into a four-door supercar contender. With a boosted twin-turbo V8 engine producing 605 horsepower, this model pushes boundaries in speed, handling, and refinement, making it a standout in the ultra-luxury performance segment.

Powertrain Excellence: A Twin-Turbo V8 Beast

At the heart of the 2016 Audi S8 Plus lies a 4.0-liter twin-turbocharged V8 engine, meticulously tuned for explosive performance. This powerplant delivers 605 horsepower between 6,100 and 6,800 rpm, surpassing the standard S8 by 85 hp and approaching the output of Audi’s R8 V10. Torque figures reach 517 lb-ft normally, spiking to 553 lb-ft during overboost phases above 4,000 rpm, providing relentless thrust.

Paired with an 8-speed ZF Tiptronic automatic transmission, power flows seamlessly to all four wheels via Audi’s quattro all-wheel-drive system. This setup ensures optimal traction in all conditions, from dry tarmac to slippery surfaces. The gearbox offers quick shifts, though manual paddle interventions can occasionally overwhelm it under extreme loads.

Performance metrics are staggering: 0-60 mph in as little as 3.3 seconds, 0-100 mph in 7.8 seconds, and a top speed of 190 mph (305 km/h) with the optional Dynamic package. Real-world tests confirm this surge continues well beyond 60 mph, turning highway merges into effortless overtakes.

Chassis and Dynamics: Precision Meets Comfort

The S8 Plus features an adaptive air suspension retuned for sportier responses, allowing it to handle like a midsize sports sedan despite its 4,600-pound curb weight. In Comfort mode, it glides over imperfections; switch to Dynamic, and it transforms into a corner-carving machine with minimal body roll.

Standard carbon-ceramic brakes provide fade-free stopping power, essential for repeated high-speed runs. The Dynamic package adds a sport exhaust for a deeper growl and further sharpens the steering, which feels more connected than in prior models.

Interior Refinement: Opulence and Technology

Step inside the S8 Plus, and you’re enveloped in premium materials: supple leather, Alcantara suede headliner, and contrasting red stitching. Front seats offer 22-way power adjustments, heating, ventilation, and massage functions for long-haul comfort. The driving position is near-perfect, with excellent visibility and support for taller drivers.

Rear seating provides adequate legroom for adults in this standard-wheelbase sedan, outperforming rivals like the Jaguar XJR in headroom. Optional rear massage seats elevate luxury further.

Technology abounds with standard Audi Connect (WiFi hotspot, live traffic), a full assistance suite (adaptive cruise, lane assist, parking aids), and the intuitive MMI infotainment system. The cabin feels driver-focused yet welcoming for passengers.

• Alcantara-trimmed headliner for a sporty touch
• S8 badging on seats, no ‘Plus’ designation
• Ambient lighting and high-quality plastics throughout
• Optional Bang & Olufsen audio for immersive sound

Fuel Economy and Practicality

Despite its power, the S8 Plus achieves 15 mpg city and 25 mpg highway, respectable for the class thanks to efficient turbocharging and cylinder deactivation. The trunk is modestly sized, a common critique in this segment, prioritizing performance over cargo space.

All-wheel drive ensures year-round usability, excelling in snow or rain. However, the short-wheelbase limits rear legroom compared to long-wheelbase rivals like the Mercedes S-Class.

Design and Styling: Subtle Yet Menacing

Exterior updates for the Plus include quad exhaust tips, aggressive front fascia, and optional matte finishes with carbon accents. At 17.5 feet long, it cuts an imposing figure without screaming for attention. 21-inch wheels fill the arches, shod in high-performance tires.

Audi’s signature LED matrix headlights and sleek lines maintain elegance, blending with the brand’s design language while hinting at the power within.

Ownership Considerations: Pricing and Value

Base pricing started around $115,000, with loaded Dynamic package models reaching $153,000. Today, used examples depreciate to about $28,000-$38,000, offering strong value for the performance. Maintenance costs are premium, but standard equipment mitigates the need for options.

Rivals include the Mercedes S63 AMG, BMW M5, and Porsche Panamera Turbo. The S8 Plus edges them in straight-line speed and all-weather grip.

Driving Impressions: A Four-Door Supercar

On the road, the S8 Plus feels otherworldly. Acceleration pins occupants back, with turbo boost building a seamless wave of power. Highways become playgrounds, and twisty roads reveal composed handling. The exhaust note in Dynamic mode adds theater without drone.

Comfort mode suits daily duties, isolating noise and bumps effectively. It’s a grand tourer at heart, capable of 190 mph runs or relaxed cruises.

Pros and Cons

• Pros: Insane acceleration, all-weather AWD, luxurious interior, advanced safety tech, ceramic brakes standard.
• Cons: Firm ride in Comfort mode on poor roads, limited rear space, smaller trunk, high fuel and insurance costs.
