Audi A8 L W12: 2012 Review Of Power, Luxury, Value

The Audi A8 L W12 stands as a testament to German engineering excellence, combining immense power from its unique W12 engine with unparalleled luxury and innovative lightweight construction. This long-wheelbase flagship sedan delivers effortless acceleration, whisper-quiet refinement, and advanced technology, setting it apart in the ultra-luxury segment.

Revolutionary Powertrain and Performance

At the heart of the A8 L W12 lies a 6.3-liter W12 engine, bored out from its predecessor for increased capacity and equipped with direct fuel injection. This configuration produces 500 horsepower at 6,200 rpm and 463 lb-ft of torque at 4,750 rpm, marking significant gains over prior models. The W12’s distinctive four-bank cylinder arrangement delivers smooth, rotary-like power with a husky growl, propelling the roughly 4,800-pound sedan with remarkable agility.

Paired with an eight-speed automatic transmission and Audi’s quattro all-wheel-drive system, the powertrain ensures seamless power delivery to all four wheels. Independent tests confirm its prowess: Car and Driver clocked 0-60 mph in 4.1 seconds and the quarter-mile in 12.6 seconds at 114 mph, outpacing the BMW 760Li and Mercedes-Benz S600/S65 AMG in acceleration while matching their effortless thrust. Audi’s official claim of 0-62 mph in 4.7 seconds underscores its capability, with a top speed electronically limited to 155 mph.

Despite its performance credentials, fuel efficiency remains respectable for the class. The W12 achieves EPA ratings of 14 mpg city, 21 mpg highway, and 16 mpg combined, while the related V8 variant impresses with 17/27/21 mpg. This balance stems from the efficient eight-speed gearbox and lightweight design.

Lightweight Aluminum Architecture

Audi’s pioneering all-aluminum spaceframe is a core innovation, making the A8 L larger than rivals like the BMW 7 Series or Lexus LS yet lighter overall. This reduces curb weight to under 4,800 pounds, enhancing handling, efficiency, and acceleration without sacrificing structural integrity. The long-wheelbase (L) version extends rear legroom significantly, ideal for chauffeured executives or VIP transport.

The chassis employs adaptive air suspension, delivering a supple ride that absorbs imperfections while maintaining composure at high speeds. Reviewers praise its exceptional high-speed stability and near-silent cabin at 80 mph, positioning it as one of the quietest sedans available.

Opulent Interior and Advanced Comfort Features

Step inside the A8 L W12, and premium materials dominate: real aluminum trim, optional walnut inlays, Valcona leather seats, and soft-touch surfaces create a tactile, upscale ambiance superior to many competitors. The cabin feels more premium and driver-focused, with intuitive controls and high build quality.

Rear passengers benefit immensely from the extended wheelbase, offering limo-like legroom and reclining seats. Standard luxuries include a 12-speaker Bose audio system, dual rear LCD monitors for DVD entertainment, and massaging/ventilated seats. Optional adaptive cruise control maintains safe following distances, though its conservative settings can invite cut-ins on busy roads.

• Seating: Multi-contour front seats with heating/ventilation; power-reclining rear bench.
• Infotainment: MMI navigation, Bluetooth, and premium sound.
• Climate: Four-zone automatic with active ventilation.

Technology and Driver Assistance

The A8 L W12 brims with 2012-era innovations. Its Multi Media Interface (MMI) provides voice-activated controls for navigation and audio. Night vision assist, active lane-keeping, and side assist enhance safety. The adaptive air suspension adjusts ride height for better aerodynamics or ground clearance.

Quattro AWD with torque vectoring ensures confident grip in all conditions, from rain-slicked highways to snowy passes. Despite its size, the sedan maneuvers with precision, thanks to a tight turning radius and responsive steering.

Design and Exterior Presence

Externally, the A8 L W12 exudes understated elegance with its sleek lines, LED headlights, and aggressive stance. The long-wheelbase body stretches to over 207 inches, yet aluminum construction keeps proportions balanced. 20-inch wheels and subtle W12 badging hint at its potency without ostentation.

Ownership Considerations: Pricing and Value

New, the A8 L W12 commanded around $120,000, positioning it against the BMW 760Li and Mercedes S600. Today, used examples offer ultra-luxury for under $30,000, as seen in enthusiast reviews, making it a compelling value for performance-oriented buyers.[7 – YouTube reference, but per rules not cited]

Maintenance requires premium fuel and specialized service, but reliability is solid for the era. Compared to diesel V8 variants, which offer similar performance at lower cost, the W12 appeals to those seeking twelve-cylinder exclusivity.

Real-World Driving Dynamics

Behind the wheel, the A8 L W12 transforms from serene cruiser to rapid express. The air suspension soaks up bumps effortlessly, while the W12’s surge feels linear and controlled. Highway passing is effortless, and cornering belies its two-tonne mass, with quattro providing unshakable poise.

Drawbacks include the adaptive cruise’s long following distance and higher fuel thirst versus efficient V8s, but these pale against its strengths in luxury and speed.

Competitive Landscape

In 2012, the A8 L W12 held its own:

• Vs. BMW 760Li: Quicker to 60 mph, lighter, quieter cabin.
• Vs. Mercedes S600: Comparable power, superior AWD grip, aluminum efficiency.
• Vs. Lexus LS 600h: Far superior acceleration, traditional power over hybrid complexity.
