BMW 8-Series Vs Mercedes S-Class: Which Of Germany’s Luxury Convertibles Do You Like Best?

Even though BMW’s all-new 8-Series Convertible is a tad smaller than Mercedes-Benz‘s S-Class Cabrio, there’s no denying that they’re aimed at the same market and that there a lot of parallels to be drawn between the two, especially if you look at them as luxury 2+2 drop tops.

Otherwise, you’re faced with the fact that the S-Class is bigger and considerably more expensive, but we’ll get into those figures a little later on. First, let’s talk about aesthetics.

Plenty of glamour to go around

You can argue that BMW did a very solid job with the new 8-Series, as the car looks properly sporty and elegant at the same time, something the old 6-Series Coupe/Cabrio wasn’t as good at.

It all starts with that wide kidney grille and those sharp headlights, which together with the dual-crease hood and aggressive-looking front bumper give the 8er a really menacing “face”. It’s almost like it’s angry about something.

Move to the rear and you’ll find a slightly more elegant demeanor, although it’s certainly nowhere near as stylish as the Mercedes, whose design language could almost be described as timeless.

The sheer size of the S-Class Cabriolet also goes on to help it in the styling department. The bigger the wheelbase, the more you can afford to stretch out the exterior design and make the product look sleeker – it’s why the two-door versions of the S-Class tend to look better proportioned than their C-Class and E-Class siblings.

Just how big of a difference is there you ask? Well, the 8-Series Convertible measures 4,851 mm (190.9 in) in length, 1,902 mm (74.8 in) in width, 1,345 mm (52.9 in) in height and has a 2,822 mm (111.1 in) wheelbase. The S-Class Cabrio on the other hand is 5,051 mm (198.8 in) long, 1,913 mm (75.3 in) wide, stands 1,428 mm (56.2 in) tall and has a 2,945 mm (115.9 in) long wheelbase.

The very best in on-board tech

Regardless of which of the two you prefer, know that they both feature the very best when it comes to available on-board technology. The S-Class is still Mercedes’ most popular luxury nameplate, whereas the 8-Series is also right up there with Bavaria’s finest, like the 7-Series and the X7.

What you might not be able to escape is that sensation of timeless luxury that you get in the Mercedes, while the BMW has a more modern-looking dashboard, which also happens to be driver-focused (somewhat), unlike the S-Class’.

While we’re sure that most of you can appreciate both interiors, we reckon buyers will simply go for whichever model best suits their image, especially since from a practical standpoint, the two cars are indeed similar: both are ultra-expensive convertibles with potent engines, excellent tech and well-put-together interiors.

Speaking of money, this BMW M850i xDrive Convertible has been assigned a base price of $121,400 in the U.S., making it $9,500 more expensive than the Coupe version. The S-Class costs more, any way you look at it: the entry-level S 560 Cabriolet is priced from $133,300, whereas the AMG-powered S63 version will set you back at least $179,500.

So there you have it. Sure, they may not compare all that well from all points of view, but the bottom line is this: If you want a large luxury 2+2 convertible and you’d love to shortlist something that’s sort of in the same ballpark as the Mercedes S-Class, your only alternative is the new BMW 8-Series, at least until Bentley launches its all-new Continental GTC that is.

    Give me the Merc thanks.

  • atomicbri


  • Bash

    I love the side profile of the BMW, but at the end of the day, i’d Rather have the Benz key fob in my pocket. I would definitely choose the Merc here, just with a darker paint job, and a different interior color as well.

  • Merc1

    So if we’re talking M850i vs S560 I’ll go for the BMW M850i Cabriolet. Now what is pictured is the S63 Cabriolet which I will take over the M850i Cabrio. Will have to look at this again when the M8 Cabriolet arrives.


    • Сафиуллина-Мохамед Рамазанов

      Agree sir

  • DanSemering

    The MX-5

  • TheBelltower

    Both of these are gorgeous. I’d go for the BMW because it’s a newer design. And because the Mercedes doesn’t really turn heads. It could be an E-class. Or at first glance, even a C-class. They all look good, but if I’m dropping this kind of money I don’t want it to resemble a car that costs half as much.

    • OdysseyTag

      With you there.

    • Mynameis Taylor

      sorry, buddy.. but the S Class has presence you won’t confuse it for an E class on the road. Also ,there’s a difference between the cars resembling the FLAGSHIP, rather than 5 and 7 serious looking like a 3 serious.

      • TheBelltower

        If you say so.

  • Marwan Abdul Hak

    Different size categories in my opinion. Even the dimensions of the E cabriolet is slightly bigger then the 8 series. That said, merc all the way ( but i prefer the coupé)

  • Jason Panamera

    8 Series in terms of dimensions plays on the same field as E Class coupe. In S Class coupe you can easily sit behind the driver, in E Class coupe also but in 8 series 2nd row is just for isofix. The problem with E Class coupe is it looks too smiliar to C class coupe what makes E class less prestigious for me. I mean all mentioned above cars are beautiful inside and outside but only S class seems like really luxury coupe. I compared S coupe, E Coupe and 8 series with similar engines powers and equipment and 8 series was about 15-20 k more expensive than E coupe ( not that much) , not mentioning about S Class which was always above the price of 8 series. Personally I’d choose 8 series. I just love it’s design, especially front of the car.

  • Javier Casabe

    i like front and back of the BMw with the profile view of the mercedes! haha

  • Momogg


  • Bimmer looks better.

  • Ermal Morina

    Definitely the Mercedes,it just suits my taste

  • PK

    bright colors suits the benz while dark colors suits the bmw. both of them should stick to that tradition.

  • Mynameis Taylor

    The Merc.. handsdown the winner for me, aesthetically speaking.

  • Mynameis Taylor

    i agree. Doesn’t even look to be in the same class as the S Class

  • Six Thousand Times

    The BMW looks more sleek and is almost certainly the driver’s option but if you can still get a V-12 in that bubble-butt Benz…

  • lustratum

    BMW for sure

  • An Existing Person

    I’m not sure if I would even put the two in the same class. The Mercedes just oozes class and excellence, and the Coupe/Cabriolet has a presence on the road in a way that no BMW could. I can’t help but look at the BMW and see just a rebadged 6-Series. Sure, the BMW might behave better dynamically, but then again if you wanted dynamics you would buy a Porsche and neither of these.

  • SteersUright

    Benz on the inside, BMW just a tad newer and fresher on the outside. In all fairness, the S-class coupe is hardly new at this point, though, and it still looks great. That said, neither of the land yachts is appealing to me personally and I’d have so many other coupes at these price-points.

  • C Noi

    8 con look better than 8 coup. But s coup/con more elegance

  • Tinky-Winky

    No poll? :*(

    • Nordschleife

      They never make them. It’s like they don’t want an easier way to answer these questions.

  • botornot387

    BMW for sure!

  • Dan Iosubescu

    Mercedes S-Class Cabriolet …. of course !!!

  • PK

    if you want a luxury yacht then buy the s class coupe convertible. if you want a sports boat then buy the 8 series convertible. simple as that.

    • Kagan

      no buy a 911 cabrio.

      • PK

        porsche wish they were like mercedes and bmw! lol

        • Ary Wisesa

          Quite contrary, it’s Mercedes and BMW that wish to be like Porsche. Just look at AMG GT & AMG GT4, they are clearly 911 & Panamera Turbo wannabes, respectively. Even SLK and Z4 can’t match Porsche Boxster.

          • PK

            but who sells more and has the popularity? exactly. performance is one thing but the attraction is another. which porsche lacks.

  • ErnieB

    Merc interior is uniquely merc.. bmw’s looks soo generic..

  • Ary Wisesa

    Mercedes S Class Coupe, but with original grille, not that hideous panamericana grille.
