The world of luxury sedans is a realm of opulence, power, and unparalleled comfort. For decades, Mercedes-Benz has been synonymous with this class, and the W140 S-Class stands as a monument to their engineering prowess. But when we talk about the absolute pinnacle of automotive luxury, names like Bentley inevitably enter the conversation. Imagine a Mercedes-Benz so refined, so effortlessly smooth, it feels like it’s almost flying – that’s the level of experience we’re exploring when comparing the best of Mercedes to a marque like Bentley. While the idea of a “Flying Mercedes Benz” might be a dream, today, we’re diving deep into a real-world comparison: a Bentley sedan versus the legendary Mercedes-Benz W140 sedan, focusing on comfort, performance, and the overall driving experience.
The original article sparked a fascinating debate, typically centered around coupes and GTs, but this comparison zeroes in on the sedan versions, putting family comfort and daily drivability at the forefront. The author of the original piece, much like many of us, harbored skepticism that anything could truly surpass the W140 in comfort. Let’s unpack this head-to-head battle of luxury titans.
Power and Performance: Under the Hood
When it comes to raw power, the Bentley, equipped with a W12 engine, is undeniably in a different league. Boasting 552 horsepower and matching torque, it’s engineered for effortless performance. The fuel economy, as noted, sits at 11 mpg in the city and 18 mpg on the highway.
In contrast, the Mercedes-Benz W140 S500 sedan, with its V8 engine, delivers a respectable 315 horsepower. Fuel consumption is slightly better in the city at 14 mpg but matches the Bentley on the highway at 18 mpg (or 11/15 mpg for the V12 S600 variant).
While the Bentley offers a significant power advantage, the W140 is no slouch. For everyday driving, the W140’s power is more than sufficient, but the Bentley’s sheer force is always on tap, offering a different kind of driving experience – one of almost limitless potential.
Comfort and Interior: Where Luxury Resides
The heart of the original comparison lies in comfort, a traditional stronghold for the W140. The author initially leaned towards the W140’s “plushier seats” as the definitive winner. However, the Bentley’s highly adjustable seats, including shoulder angle adjustments, proved to be a game-changer. While the Bentley seats are firmer, this adjustability allows for a truly customized fit, potentially making them more comfortable for long journeys once perfectly configured. This bespoke comfort experience is a hallmark of ultra-luxury brands like Bentley, going beyond mere plushness to personalized ergonomics.
In terms of size, both cars are remarkably similar in length and width. However, the Bentley ingeniously maximizes interior space by having a shorter and more compact engine bay. This design choice translates to more room for passengers, especially in the rear, where occupants enjoy comparable space to those in the front.
Suspension and Ride Quality: Gliding vs. Sporty Firmness
Suspension is where the W140 truly shines in terms of classic Mercedes-Benz comfort. The original author rightly points out the W140’s “plushness and road feel,” where road imperfections virtually disappear. The Bentley, even in comfort mode, leans towards a firmer, more “sportscar-like” ride. The difference between comfort and sport modes in the Bentley is subtle, indicating its inherent sporty nature. You feel the road texture in the Bentley, whereas the W140 isolates you in a bubble of smoothness. If the goal is to feel like you’re “flying” over the road, the W140’s suspension delivers a more traditional luxury sedan experience.
Interior Quietness and Sound: Auditory Luxury
In cabin quietness, the Bentley takes the lead. Despite not having double-paned windows like some luxury cars, the Bentley’s superior sound insulation, evidenced by thicker door padding, creates a remarkably serene environment. The author notes being able to hear the W140’s auxiliary fans even on low, while the Bentley remains whisper-quiet even with fans at full speed. This level of auditory refinement contributes significantly to the overall sense of luxury and relaxation within the Bentley.
However, when it comes to the sound system, the W140 unexpectedly reclaims ground. The original author praises the W140’s sound system, finding the Bentley’s lacking in bass and overall fullness. The W140’s audio is so impressive that the author claims it rivals aftermarket systems costing thousands of dollars. This highlights a surprising strength of the older Mercedes-Benz, where sound quality was clearly a priority.
Practicality: Trunk Space and Ease of Use
For practicality, the Bentley boasts a significantly larger trunk, estimated to be “2-3 W140 trunks” in size. The added convenience of a trunk access slot behind the rear armrest further enhances its usability. Like the W140, the Bentley also offers space for features like a mini-fridge, catering to the needs of luxury travelers.
Ease of driving, however, leans back towards the W140. The Bentley’s stiffer steering requires more effort, especially for sharp turns. The gas pedal response is also described as less linear and predictable compared to the W140’s smooth and consistent acceleration. The Bentley, despite its advanced technology, can feel heavier and less nimble in everyday driving situations.
Unique Features and Road Presence: Standing Out in Style
The Bentley in the comparison comes with a unique solar sunroof, powering interior fans to circulate air when parked – a thoughtful feature for hot climates. The multi-key memory system, storing individual driver settings, is another modern luxury touch. The Bentley’s headliner, made of thick leather, and the presence of two car batteries in the trunk, further emphasize its opulent and robust engineering.
In terms of road presence, both cars command attention, but the Bentley stands out more overtly. Interestingly, the author notes increased instances of “brake checking” while driving the Bentley, suggesting it attracts more attention, both positive and potentially negative, from other drivers. The Bentley’s prestige also seems to translate to tangible benefits in business settings, where it commands a certain level of respect and seriousness.
Reliability and Maintenance: The Cost of Luxury
Reliability is a complex area. The author suggests the Bentley may have an edge in engine and transmission reliability based on online forums, while the W140 might be more robust in electronics (excluding the wiring harness issue common in W140s). Surprisingly, some Bentley parts are reported to be cheaper than W140 parts. However, Bentley maintenance presents unique challenges. DIY repairs are discouraged by the manufacturer’s design, with simple tasks like headlight replacement requiring expensive dealer service. Replacement keys are also significantly more costly for the Bentley. The use of shared VW parts in the Bentley offers potential savings if the correct part numbers can be identified.
Overall Impression: Choosing Your Luxury Experience
The original author concludes that, overall, the Bentley is “better,” citing its fun factor, potentially cheaper maintenance (excluding specific expensive parts), and greater visual appeal. However, for daily driving, the W140 is favored for its plusher suspension and easier steering, making commuting less stressful. The W140 is praised as a comfortable “all-day sofa,” highlighting its enduring appeal for relaxed, comfortable cruising.
Ultimately, the choice between a Bentley and a W140 Mercedes-Benz sedan depends on individual priorities. The Bentley offers unparalleled power, bespoke luxury, and a more modern, sporty driving experience. The W140 prioritizes classic Mercedes-Benz comfort, a smoother ride, and a more relaxed driving demeanor. While the “flying Mercedes Benz” might remain a dream, both these sedans represent the pinnacle of automotive engineering in their respective eras, offering distinct interpretations of luxury and performance. For those seeking ultimate comfort and a classic luxury experience, the W140 remains a compelling choice, while the Bentley caters to those desiring cutting-edge performance and a more overtly opulent statement.
