2014 Audi S8: Performance Luxury Sedan Review

The 2014 Audi S8 stands as a remarkable achievement in automotive engineering, seamlessly blending the sophistication of a luxury flagship with the raw performance characteristics typically reserved for dedicated sports cars. This comprehensive examination explores the vehicles defining characteristics, technological innovations, and the driving experience that positions it among the most compelling performance sedans available. Whether you prioritize speed, comfort, or cutting-edge technology, the S8 delivers across all dimensions with unwavering consistency.

Powertrain Excellence: Engineering Performance at Scale

At the heart of the 2014 S8 resides a formidable twin-turbocharged 4.0-liter V8 engine that produces 520 horsepower and 479 pound-feet of torque. This substantial power output represents a significant upgrade from the standard A8, demonstrating Audi’s commitment to creating a genuine performance variant rather than simply a cosmetically enhanced version. The addition of the second turbocharger fundamentally transforms the driving character, delivering acceleration that rivals vehicles costing significantly more.

The propulsion system achieves the sprint from standstill to 62 miles per hour in merely 4.1 seconds, a figure that places the S8 in territory typically occupied by exotic sports cars. What makes this achievement particularly noteworthy is the manner in which the acceleration occurs: with near-total refinement and without any jarring sensation. The turbocharged V8 spools up so swiftly that the forced-induction nature of the engine becomes nearly imperceptible to occupants, creating an experience of continuous, fluid power delivery rather than turbo lag or sudden boost onset.

The eight-speed automatic transmission paired with the V8 plays a crucial supporting role in this performance narrative. This gearbox cycles through its ratios with such speed and smoothness that transitions between gears remain virtually unnoticed during aggressive driving or casual commuting. The transmission’s intelligence allows it to anticipate gear changes, maintain optimal engine characteristics across the power band, and deliver power to all four wheels through Audi’s proven all-wheel-drive system.

Efficiency Without Compromise: The Cylinder Deactivation Innovation

Perhaps one of the S8’s most ingenious engineering solutions addresses the apparent contradiction between extreme performance and fuel consumption. Audi engineered a sophisticated cylinder deactivation system that essentially transforms the thunderous 4.0-liter V8 into a more economical 2.0-liter four-cylinder configuration during urban driving or highway cruising. The transition between these operational states occurs with such seamlessness that occupants remain unaware the system is operating.

This technology proves particularly intelligent in its application, activating more frequently in low-speed urban environments where fuel conservation provides meaningful benefits, while remaining deactivated during highway driving or spirited acceleration. The result manifests in a combined fuel economy rating of 19 miles per gallon, a genuinely impressive figure for a vehicle delivering 520 horsepower. This efficiency achievement underscores Audi’s engineering prowess in refusing to accept traditional trade-offs between performance and consumption.

Handling Dynamics: Size Transcended Through Engineering

The 2014 S8’s handling characteristics represent perhaps its most surprising strength. Despite tipping the scales at over 2,000 kilograms and stretching nearly two meters in width, the vehicle exhibits agility that recalls machines substantially smaller and lighter. This unexpected nimbleness stems from multiple integrated systems working in concert: sports adaptive air suspension, variable steering geometry, and a mechanical differential calibrated for performance driving.

The air suspension system deserves particular attention for its dual nature. In comfort-oriented modes, the suspension filters road imperfections with remarkable effectiveness, creating an experience of gliding above imperfections rather than traversing them. This capability proves especially impressive considering the S8 wears low-profile 21-inch performance tires that typically transmit more road feedback than conventional tire-and-suspension combinations. Yet when the driver engages dynamic mode, the same suspension firms up considerably, transforming the vehicle’s handling response and enabling cornering speeds that defy the S8’s substantial dimensions.

The variable steering system complements the suspension’s contributions by adjusting both its ratio and response characteristics based on speed and driving mode. At parking speeds, the steering becomes increasingly responsive to avoid excessive effort during low-speed maneuvers. Conversely, at highway speeds, the system becomes more progressive, providing stability while maintaining directional precision. This engineering sophistication creates a vehicle that remains effortless to pilot through narrow urban streets yet capable of executing tight lane-change maneuvers on congested highways.

Technological Integration: The Connected Flagship

The 2014 S8 represents Audi’s vision of an intelligent, connected flagship that anticipates occupant needs through integrated technology. The vehicle arrives equipped with navigation systems, 3G connectivity, and wireless hotspot capabilities that transform it into a mobile office for professionals demanding connectivity while traveling. These systems integrate seamlessly with the vehicle’s entertainment and climate control infrastructure, creating a unified technological ecosystem rather than a collection of isolated features.

A particularly noteworthy technological achievement involves the MatrixBeam LED headlamp system standard on all 2014 S8 models. This intelligent lighting solution employs an array of individually controlled LED elements that can selectively illuminate portions of the road without creating glare for oncoming traffic. The system actively tracks approaching vehicles and adjusts its beam pattern accordingly, essentially permitting the driver to maintain maximum illumination while automatically preventing distraction to other road users. This represents a substantial leap forward in lighting technology, demonstrating how incremental innovations can meaningfully enhance the driving experience.

The vehicle’s comprehensive safety architecture incorporates blind-spot monitoring and rear collision alert systems as standard equipment on the 2014 model year. These systems transform the S8 into a platform that actively protects occupants through both passive structural design and active intervention technologies. The combination of multiple radar sensors, cameras, and algorithmic processing creates a protective bubble around the vehicle, alerting drivers to potential hazards before dangerous situations develop.

Interior Refinement: Luxury Redefined

Stepping into the S8’s cabin reveals a space where materials, design, and ergonomic consideration converge into an environment reflecting the vehicle’s premium positioning. The interior employs leather throughout, complemented by plush carpeting and suede trim elements, creating tactile richness that acknowledges the S8’s four-figure monthly payment. Every control, from climate settings to entertainment management, operates with the silky smoothness expected of equipment designed for executives accustomed to first-class accommodations.

The heated and cooled seat systems extend beyond mere comfort features, actually contributing to overall cabin thermal management and occupant wellness during extended driving. When occupants sink into the S8’s supportive seats during a morning commute, the vehicle intuitively adjusts seat and steering wheel heating to counteract morning chill. Similarly, during warm afternoons, the cooling function prevents heat-related fatigue during traffic-heavy drives. These seemingly minor details accumulate into an overall sense that the vehicle genuinely cares for occupant wellbeing.

Acoustic engineering deserves recognition as well, with the S8’s cabin achieving a level of quietness that borders on disconcerting. Even when maintaining speeds exceeding 100 miles per hour, a hushed calm pervades the interior, permitting conversation at normal volumes and reducing listener fatigue on extended journeys. This acoustic refinement stems from multiple engineering investments: acoustic lamination in the glass, additional sound-damping materials in the doors and floor, and careful attention to mechanical noise isolation.

Performance Comparison: Competing at the Highest Level

The 2014 S8 operates in a competitive segment where Mercedes-Benz, BMW, and Jaguar all field compelling alternatives. While the S8 may not achieve the absolute handling superiority of the Jaguar XJR or the raw horsepower of the Mercedes S63 AMG, it positions itself as the value-conscious choice for performance-oriented luxury buyers. The S8’s pricing advantage over competing German and British performance sedans proves particularly compelling for buyers who value overall capability and technological sophistication over raw specifications alone.

Driving Experience: Performance Without Pretension

One of the most distinctive characteristics of the 2014 S8 involves the manner in which it delivers its extraordinary performance. Unlike vehicles that announce their power with aggressive exhaust notes and visible aggression, the S8 operates with almost understated sophistication. You can comfortably maintain 100 miles per hour on an autobahn without consciously monitoring your speed, the vehicle’s composed demeanor belying its velocity. This characteristic proves either refreshing or potentially disappointing depending on buyer preferences—those seeking visceral feedback might find the experience too refined, while luxury-first buyers will appreciate the effortless performance delivery.

The air suspension’s intelligent algorithm constantly monitors road surfaces, adjusting stiffness many times per second to optimize the balance between comfort and control. On deteriorated urban streets littered with potholes and patched asphalt, the system filters imperfections with nearly magical effectiveness. Simultaneously, when encountering a smooth mountain pass calling for aggressive cornering, the same suspension enables performance that belies the vehicle’s size.

Value Proposition: Premium Pricing with Performance Justification

The 2014 S8’s base price of $112,500 positions it in the upper echelon of performance sedans, yet this figure represents substantially less than several competing alternatives. The value equation improves further when considering that the S8 includes all-wheel drive as standard equipment and delivers efficiency capabilities through cylinder deactivation technology that competitors charge extra for or simply don’t offer.

Long-term ownership costs reflect the S8’s position as a maintenance-intensive performance vehicle. The complexity of twin-turbo systems, adaptive air suspension, and advanced electronics suggests that maintenance expenses will exceed those of less sophisticated competitors. However, Audi’s warranty coverage of four years and 50,000 miles provides meaningful protection during the critical early ownership period.
