There’s something enduringly elegant about a luxury sedan—especially one that balances cutting-edge technology, effortless power, and limousine-like comfort. In India, this segment has become a quiet yet consistent battleground for three formidable contenders: the Audi A6, BMW 5 Series LWB, and the Mercedes-Benz E-Class LWB.
While the new-generation BMW 5 Series LWB and the all-new E-Class LWB made their debut in 2024, the Audi A6 continues with the generation that’s been around since 2019—albeit with a few updates in 2023 to stay relevant. Globally, Audi has unveiled the next-gen A6, and it’s expected to arrive in India by 2026. So, in many ways, the A6 is the elder statesman here, holding its own among fresher competition.
And while all three sedans deliver a refined driving experience, it’s worth noting that only Mercedes-Benz offers a diesel variant. The Audi and BMW models come with petrol powertrains only—something to consider depending on your driving needs.
With long-wheelbase versions now available from both BMW and Mercedes, these cars don’t just drive well—they pamper, especially in the back seat. If you’re contemplating which one deserves that coveted spot in your garage, let’s dive into their unique stories.
Exterior Design
Audi A6: The A6’s design is a masterclass in subtlety. It doesn’t scream for attention, but it holds it—with a wide Singleframe grille, elegant Matrix LED headlights, and a clean profile that reflects Audi’s signature minimalism. The rear, adorned with wide taillamps and tasteful chrome, finishes the look with quiet authority.
BMW 5 Series LWB: In contrast, the BMW leans into sportiness. Its illuminated kidney grille is hard to miss, especially after dark, while adaptive LED headlamps and a muscular bumper add to the assertive presence. The Hofmeister kink and trim-specific accents lend an unmistakable sense of performance wrapped in polish.
Mercedes-Benz E-Class LWB: This one’s the grand arrival. The E-Class LWB wears its size with grace. The avant-garde grille, intricate 3D tail lights, and AMG Line trim bring together elegance and drama—a perfect blend of boardroom and ballroom.
Interior and Rear Seat Comfort
Audi A6: Step inside, and the A6 envelops you in clean lines, soft-touch materials, and tech-forward minimalism. The rear seat is generous but more functional than indulgent, featuring manual rear door sunblinds and lacking a recline option. It’s comfortable, but not as opulent as the others.
BMW 5 Series LWB: BMW has taken the rear seat experience seriously in terms of design, but with some limitations. The sculpted rear seats feature a fixed 31-degree recline—comfortable, yet not adjustable, which may be a dealbreaker for those seeking flexibility. Also notably missing are sunblinds, which feel like an oversight in an otherwise plush rear space. That said, ambient lighting, tablet holders, and premium vegan leather do add a touch of indulgence.
Mercedes-Benz E-Class LWB: This is where the E-Class shines brightest. Rear seat passengers get electric recline up to 36 degrees, extendable under-thigh support, neck pillows, electric sunblinds, and even wireless charging. It’s a first-class experience tailored for India’s luxury-conscious buyers.
Technology and Infotainment
Audi A6: The A6’s tech approach is sophisticated yet restrained. It features a 10.1-inch MMI touchscreen for infotainment and a 12.3-inch Audi Virtual Cockpit Plus for the driver. Additionally, there’s an 8.6-inch lower touchscreen that handles climate control and seat settings—an intuitive setup that gives the cabin a clean, futuristic feel. Haptic feedback across the screens adds a premium layer of interaction, even though the interface is slightly less dynamic than newer rivals.
BMW 5 Series LWB: BMW offers a more immersive setup with its curved display, integrating a 14.9-inch infotainment touchscreen alongside a 12.3-inch fully digital driver display. Combined with the sleek BMW Interaction Bar, wireless Apple CarPlay/Android Auto, and a 655W 18-speaker Bowers & Wilkins sound system, it creates a tech-savvy yet tasteful experience.
Mercedes-Benz E-Class LWB: The E-Class raises the bar with its MBUX Superscreen—a seamless glass panel that stretches across the dashboard, housing a 14.4-inch central touchscreen and a 12.3-inch passenger display. Add a fingerprint sensor for personalization, a selfie/video conferencing camera, and AI-powered “MBUX Routines,” and you’ve entered the realm of digital luxury. The 17-speaker Burmester® 4D surround system with Dolby Atmos is an aural treat.
What further sets the E-Class apart is its Chauffeur Package, which integrates luxury and tech in the rear seat: passengers can electronically move the front passenger seat forward for additional legroom, operate all rear sunblinds and sunroof shades from either rear door, and enjoy a rear center armrest equipped with wireless charging.

Safety Features
All three sedans are loaded with safety tech—8 airbags, 360-degree cameras, parking sensors, and stability control come standard. But:
BMW brings in semi-autonomous tricks like Parking Assistant Professional.
Mercedes-Benz layers on systems like PRE-SAFE, blind spot assist, and an additional centre airbag.
Audi covers the essentials well, but skips the advanced driver assistance systems found in the other two.
Engine and Transmission
Audi A6: A 2.0L turbo-petrol that pushes 265 hp, paired to a 7-speed S tronic, does 0–100 in 6.7 seconds. Smooth and efficient.
BMW 5 Series LWB: 2.0L TwinPower Turbo, good for 258 hp and 400 Nm. With an 8-speed Steptronic and a 48V mild hybrid, it feels eager and responsive.
Mercedes-Benz E-Class LWB: Three variants, from the efficient E220d diesel to the punchy 381 hp E450 4MATIC that does 0–100 in a brisk 4.5 seconds. All use a refined 9-speed automatic and mild hybrid tech.
Alloys and Tyres
Audi A6: Comes with elegant 18-inch alloys, with 19-inch options for added flair.
BMW 5 Series LWB: The 5 Series LWB was launched with 18-inch standard alloys with 19-inch as an option. Recently, the company introduced 19-inch M alloys as standard, which certainly ups the style quotient.
Mercedes-Benz E-Class LWB: Whether it’s multi-spoke elegance or AMG aggression, the 18-inch wheels are perfectly matched to each variant’s personality.
Ride and Handling
Audi A6: Geared more for relaxed cruising, it offers a supple ride on most roads, thanks to well-tuned suspension.
BMW 5 Series LWB: Despite the extended wheelbase, it maintains BMW’s driver-friendly character with precise handling and well-balanced weight distribution.
Mercedes-Benz E-Class LWB: The E-Class glides like a magic carpet. Thanks to its India-specific AGILITY CONTROL suspension, the rear-seat experience is unmatched. The E450’s 4MATIC adds all-weather capability.
Unique Features
Audi A6: Refined design and best-in-class touchscreen haptics.
BMW 5 Series LWB: Interaction Bar, crafted glass elements, and thoughtful touches like tablet holders.
Mercedes-Benz E-Class LWB: MBUX tech suite, AI routines, ultra-reclining rear seat, and premium ambient lighting with 64 shades.

Verdict
Each of these sedans tells a different story. The Audi A6 is the reserved, intelligent one—modern, minimal, and effortlessly smooth. The BMW 5 Series LWB is the confident performer—balanced, bold, and subtly indulgent. And then, there’s the Mercedes-Benz E-Class LWB, which walks into the room like royalty, commanding presence, comfort, and tech in equal measure.
Of course, luxury like that comes with a steeper price tag. You’ll need to shell out a bit more for the E-Class. But for those who see their car as an extension of their lifestyle—not just a means of transport—the E-Class makes a compelling case for itself. Because sometimes, the best things in life aren’t just bought—they’re experienced.
