The 2025 Audi A8 offers two distinct gas-powered models—the standard 335-hp V6 A8 and the high-performance 563-hp V8 S8—both representing the final year of the current generation before an all-electric A8 e-tron replacement potentially arrives in 2026. This positions buyers at a crossroads between purchasing proven gas technology today or waiting for Audi's uncertain electric future.
The 2025 A8 situation highlights Audi's transitional challenge in the luxury sedan market. According to Autvex market analysis, the current D5 generation has been in production since 2017, making it the oldest flagship among its German competitors[1]. While rivals like the BMW 7 Series and Mercedes-Benz S-Class have undergone complete redesigns, Audi continues with incremental updates while developing its electric successor.
This creates a unique dilemma for luxury buyers. The 2025 models remain competent and refined, but they lack the cutting-edge technology found in newer competitors. Meanwhile, the promised A8 e-tron based on the Grandsphere concept represents an exciting leap forward—if it actually materializes as planned[2].
No, the 2025 Audi A8 is definitively not a new generation. It's a carryover model continuing the D5 platform introduced in 2017 with a mild refresh in 2022[1]. Car and Driver confirms it's "starting to show its age" compared to all-new rivals, though it maintains the core qualities that define luxury sedans[3].
The unchanged platform means buyers get proven reliability but miss out on the latest safety features, infotainment systems, and electrification technology. The 2025 model year brings only minor updates including new 21-inch wheel designs for the Black Optic package and additional standard leather trim[4].
Yes, the gas-powered A8 faces discontinuation after 2025, marking the end of this generation. Industry sources indicate Audi plans to transition the A8 nameplate to an all-electric model, though exact timing remains fluid[2]. The company has confirmed development of over 20 electric vehicles by 2026, with the A8 e-tron positioned as the flagship.
However, production challenges and platform development delays could extend the gas model's availability. Audi hasn't officially announced a firm end date, leaving room for potential 2026 availability if the electric successor faces delays. Buyers seeking the traditional A8 experience should act within the 2025 model year to ensure availability.
The choice between gas and electric represents more than just powertrain preference—it's about timing and technology philosophy. The 2025 gas models offer immediate availability with proven V6 and V8 engines, extensive dealer support, and nationwide refueling infrastructure[3]. They represent traditional luxury without the learning curve of new technology.
The upcoming A8 e-tron promises revolutionary change with the PPE platform co-developed with Porsche, featuring 800-volt architecture and potentially 120-kWh battery capacity[5]. Early estimates suggest 0-60 mph times in the low 4-second range with over 400 miles of range. However, these remain projections without official confirmation from Audi.
The standard A8 continues as Audi's traditional luxury flagship, prioritizing comfort and refinement over sporting pretensions. Edmunds rates it 7.4 out of 10, noting that while competent, it lacks the wow factor expected from flagship sedans[6]. The long-wheelbase configuration remains the only option in North America, ensuring exceptional rear-seat space.
Despite its age, the A8 maintains several advantages. Standard quattro all-wheel drive provides confidence in various weather conditions, while the base price of $92,000 undercuts both BMW and Mercedes competitors by significant margins[7]. This value proposition appeals to pragmatic luxury buyers who prioritize substance over the latest technology.
The A8 55 TFSI designation represents Audi's standard luxury sedan configuration. According to Autvex testing data, this model balances performance with efficiency, though some reviewers note the engine could use more grunt for a flagship sedan[3]. The powertrain delivers smooth, predictable acceleration suitable for executive transport rather than enthusiastic driving.
Real-world performance feels adequate rather than exciting. The eight-speed Tiptronic transmission shifts imperceptibly in comfort mode, prioritizing refinement over engagement. The 48-volt mild-hybrid system enables cylinder deactivation and start-stop functionality, improving fuel economy to 22 mpg combined[3].
The turbocharged 3.0-liter V6 produces 335 horsepower and 369 lb-ft of torque, channeling power through all four wheels via the standard quattro system[3]. This output trails the BMW 740i's 375-hp inline-six and Mercedes S450's 362-hp unit, highlighting the A8's age in the segment.
Acceleration from 0-60 mph takes approximately 5.6 seconds—respectable but not remarkable for the class. The engine operates with exceptional refinement, producing minimal noise even under full throttle. However, enthusiasts seeking more power should consider the S8 or wait for the electric successor.
Changes for 2025 remain minimal, reflecting the model's end-of-lifecycle status. New features include:
These updates represent packaging adjustments rather than significant improvements, confirming this as a maintenance year before the model's retirement.
The A8 L configuration adds 5.1 inches to the standard wheelbase, creating class-leading rear legroom of 44.3 inches[7]. This exceeds the BMW 7 Series (43.3 inches) and Mercedes S-Class (43.8 inches), making it ideal for chauffeur-driven executives.
Extended-wheelbase benefits include:
The additional length doesn't compromise handling significantly, thanks to available rear-wheel steering that reduces the turning radius and enhances maneuverability in tight spaces.
The cabin showcases traditional German luxury with high-quality materials throughout. The dual-screen MMI infotainment system features a 10.1-inch upper display and 8.6-inch lower touchscreen for climate controls[7]. While not as visually dramatic as Mercedes' Hyperscreen or BMW's curved display, the system proves intuitive in daily use.
Standard interior equipment includes:
Critics praise the serene environment, with Car and Driver noting "not a bad seat in the exceptionally quiet house"[3]. However, newer Audi sedans offer more advanced technology interfaces.
The 2025 A8 starts at $92,000 for the base model, though typical transaction prices average $89,786 according to TrueCar data[7]. This positions it as the most affordable German flagship sedan, undercutting the BMW 7 Series by approximately $5,000 and the Mercedes S-Class by over $20,000.
Popular option packages include:
Fully equipped examples can exceed $110,000, though most buyers find sufficient luxury in mid-level configurations around $100,000.
The S8 transforms the A8's refined platform into a genuine performance sedan, addressing criticisms about the standard model's lack of excitement. What Car awards it 5.0 out of 5 stars, praising its ability to combine "savagely fast" acceleration with supreme comfort[8]. This dual personality defines the S8's appeal.
According to Autvex performance testing, the S8 achieves the rare balance of being both a capable luxury cruiser and a legitimate sports sedan. The transformation from the standard A8 is comprehensive, affecting not just the engine but also suspension, steering, and braking systems.
Professional reviews consistently praise the S8's completeness as a luxury performance sedan. The understated exterior provides few hints of its capabilities—only subtle badges, unique wheels, and quad exhaust tips distinguish it from the standard A8[9]. This discretion appeals to buyers who prefer their performance without ostentation.
The driving experience delivers effortless speed rather than raw excitement. The S8 covers ground at "a seriously rapid rate" according to What Car, though the excellent isolation means the experience feels muted compared to more extroverted rivals[8]. Some buyers will appreciate this refinement; others might find it too clinical.
The twin-turbocharged 4.0-liter V8 represents traditional performance luxury, producing 563 horsepower and 590 lb-ft of torque[9]. This substantial output flows through the eight-speed Tiptronic transmission and quattro all-wheel drive, ensuring consistent traction regardless of conditions.
The engine delivers its power with remarkable smoothness. Peak torque arrives at just 2,000 rpm and maintains through 4,500 rpm, creating a broad powerband that makes the S8 feel effortlessly quick in any situation. The exhaust note remains cultured—a "growl rather than an almighty roar"[8]—maintaining the car's executive character.
Official acceleration figures show 0-60 mph in 3.8 seconds, placing the S8 among the quickest luxury sedans available[9]. This performance comes without drama—the all-wheel-drive system eliminates wheelspin while the adaptive air suspension maintains composure during hard launches.
Quarter-mile times hover around 12 seconds at 115 mph, confirming genuine sports car performance. Yet the S8's true talent emerges during in-gear acceleration for passing maneuvers. The instant torque delivery makes highway merging effortless, while sport mode sharpens throttle response for more aggressive driving.
The S8's "sleeper" status comes from its ability to hide extraordinary performance behind ordinary luxury sedan appearance[9]. This approach differs from Mercedes-AMG and BMW M models that announce their intentions more boldly.
Performance-enhancing features include:
The predictive suspension reads the road ahead using cameras, adjusting damping preemptively for upcoming obstacles. This technology particularly impresses when encountering speed bumps, which the S8 crosses with minimal disturbance.
The 2025 S8 starts at approximately $126,000, representing a $34,000 premium over the standard A8[9]. This pricing undercuts the Mercedes-AMG S63 E Performance by significant margins while offering comparable real-world performance.
Standard S8 equipment beyond the A8 includes:
Most S8 buyers add few options, as the standard specification proves comprehensive. The Vorsprung model available in some markets bundles all available features for approximately $140,000.
The promised A8 e-tron represents Audi's vision for flagship luxury in the electric era. Built on the Premium Platform Electric (PPE) co-developed with Porsche, this model would compete directly with the Mercedes EQS and BMW i7[5]. However, confirmation timing remains uncertain.
YouTube channel Faster Cars reports the A8 e-tron will feature a 120-kWh battery with 800-volt architecture, enabling rapid charging and impressive range[5]. These specifications would position it among the most advanced electric sedans available, though official confirmation from Audi remains pending.
The A8 e-tron represents the complete reimagination of Audi's flagship for the electric age. Unlike the current e-tron GT, which serves as a performance-oriented four-door coupe, the A8 e-tron would maintain traditional sedan proportions while incorporating revolutionary technology[2].
Expected features include:
The Drive confirms Marc Lichte, Audi's design lead, acknowledged the A8 e-tron's development, stating it will be "one of more than 20 Audi EVs coming by 2026"[10].
The Grandsphere concept unveiled at the 2021 Munich Motor Show previews the A8 e-tron's design direction. The concept's dramatic proportions and minimalist interior represent a complete departure from traditional luxury sedan conventions[5].
Key Grandsphere features likely reaching production:
The production model will inevitably compromise some concept features for practicality, but Audi's recent electric launches suggest significant design elements will transfer.
Audi's evolving nomenclature reflects the transition to electrification. The "e-tron" suffix currently designates fully electric models, though this strategy may evolve as the lineup becomes predominantly electric[11]. The A8 e-tron would follow the established pattern seen with the Q4 e-tron, Q8 e-tron, and upcoming [A6 e-tron].
Future naming possibilities include:
Motor Trend confirms Audi added new all-electric Sportback sedans for 2026, including the A6 e-tron and S6 e-tron, suggesting the naming convention will persist[11].
The luxury sedan segment has never been more competitive, with each manufacturer pursuing different philosophies. According to Autvex's comparative analysis, the 2025 A8's position as the oldest design creates both challenges and opportunities. While it lacks cutting-edge technology, its proven reliability and lower pricing appeal to traditional luxury buyers.
Cross-shopping data shows A8 buyers frequently consider BMW and Mercedes alternatives, though brand loyalty remains strong in this segment. The S8 particularly appeals to those seeking understated performance rather than the flashier alternatives from AMG or BMW M.
The Mercedes-Benz S-Class sets the luxury benchmark with its opulent interior and advanced technology. Starting around $115,000, it costs significantly more than the A8 but justifies the premium through superior refinement and innovation[3]. The S-Class offers more powerful base engines and the dramatic Hyperscreen in EQS-influenced models.
However, the A8 counters with:
For buyers prioritizing value and all-weather capability, the A8 makes a compelling case despite its age.
BMW's redesigned 7 Series represents the A8's most direct competitor, offering similar pricing but newer technology. The 740i's 375-hp turbocharged inline-six outpowers the A8's V6 while delivering comparable efficiency[3]. BMW's latest iDrive 8 system also surpasses Audi's aging MMI in functionality.
The A8's advantages include:
Personal preference plays a significant role, with the BMW appealing to technology enthusiasts while the A8 suits traditional luxury buyers.
Mercedes-AMG discontinued the S63 for 2024-2025, leaving a gap in their lineup that benefits the S8. When available, the S63 delivered more power—typically over 600 horsepower—but at substantially higher cost[8]. The S8's 563 horsepower proves sufficient for any realistic driving scenario.
The S8's sleeper approach contrasts with AMG's extroverted style:
For executives wanting serious performance without compromise, the S8 offers an ideal solution.
Yes, by objective measures the 2025 A8 is outdated compared to newer rivals. Car and Driver explicitly notes it's "starting to show its age" with technology and features that trail the competition[3]. The infotainment system, while functional, lacks the visual impact and processing speed of newer alternatives.
However, "outdated" doesn't mean inadequate. The A8 remains supremely comfortable, impeccably built, and thoroughly refined. Some buyers actually prefer its traditional approach over the technology-heavy newer models. For those prioritizing proven reliability over cutting-edge features, the A8's maturity becomes an asset rather than liability.
This decision ultimately depends on individual priorities and timeline flexibility. Buy the 2025 A8 now if you:
Wait for the A8 e-tron if you:
Consider typical purchase timelines when making this decision. The electric model could face delays, while gas model availability diminishes as production ends.
Start by determining your powertrain preference and timeline flexibility. If proceeding with a 2025 model, test drive both the A8 and S8 to evaluate whether the performance upgrade justifies the premium. Compare directly with the [BMW 7 Series] and Mercedes S-Class to understand the technology gap.
For those considering waiting, monitor Audi's official announcements regarding the A8 e-tron timeline.
