Going from my W213 to a new W214 - Why or Why not?




The discussions are to merge:
Why Mergers of Carmakers Like Honda and Nissan Often Falter
see: https://www.nytimes.com/2024/12/24/b...ger-deals.html
A few things that I can't say are "worse," but just "different" in the sense of not necessarily needed to be changed are: the W214 Panorama Roof Control is now an annoying buttonless sliding thingamabob... which could have been a simple button like the old one. As well, I like the ambient lighting, but on the W213 it was soft and subtle while on the w214 it IS like the "German Disco" I've heard people joke about. The w214 steering wheel, which has been used for a while, isn't as easy to use as the W213 (or at least the one through 2020, when it was the simpler one and when she had the clock on the dash). FInally... yes, I love the clock and am sad they got rid of it.
Again, I don't think all of the above are "downgrades" in the sense that the quality of each is very high, and the inclusion of an analog clock I can see as out of sync with the new tech-vibe... but still I just think it might be a case of changing things just to change them. If it ain't broke... don't fix it... but then again for a car company wanting to sell NEW stuff, I get it.

• W212 had a torque gap around 30-40 mph which the 9 speed transmission corrected. It made passing from that speed somewhat sluggish. (W212 E550 - 8 cylinder - is better).
• A few versions of the 4 cylinder 27x engines have some serious/costly engine failures (cracked pistons, oil sump pump,...). Far more than the 6 cylinder W212 E350 which is likely to last longer. If buying, I would get 6 cylinders (E450) W214.
• The MBUX is less safe and harder to use than COMAND. Car magazines always put the MBUX controls in the short list of "CONS" when they review(ed) them. I have the first MBUX year (2021) and it's really bad (compared to newer models I have driven). Make sure you like the touch pads and swipes on whatever you buy.
• W212 has a spare and a CD which (optionally) allows copy of CD's to a hard drive to store music. W213 and W214 do not, although they have USB-C ports for thumb drive (or external sourced) music (not USB-A).
• W213 and W214 have large screen areas and more info on displays. W212 displays are adequate (for me).
• AEB was introduced in 2015, earlier versions of W212 only had it when DISTRONIX (option) was turned on.
• W214 has numerous problems with MBUX software, some serious, many annoying, and some taking new cars out of service for weeks.
• 2025 E350 has optional rear airbags.
A complete list of differences (Major and minor) which I found after my 2014 E350 (W212) was totaled, and I replaced it with a highly options 2021 E350 (W213) follows. I have not seen any significant upgrades (except the rear seat belts, which is significant to me) in the W214, but I’m not very knowledgeable of the W214.
W213 PROS (vs W212) Some of these are due to options I did not add to the W212
1. Engine: 4 modes (ECO, CMFRT, SPRT, SPRT+), W212 had only 2 (E and S)
2. Engine: Auto-stop at red lights (will it wear anything out? – I suppress it just in case, only works with fully charged battery.)
3. Engine: Better pickup at 30-40mph (Torque dip in W212 E350) due to 9 vs 7 speed.
4. Engine: Slightly Better City / overall Mileage
5. Outside: Better looking Hood (to some people)

W213 CONS (vs W212)
a. Engine - 6 cyl is better; Piston Cracking and Oil pump problems with some M27x engines. Get a 450

As an owner of a W213, I must say my impressions of the W214 is that it is a superior car to the W213. It looks classier inside and outside, and the evolution MB created clearly hits the mark. Yes there are a few nits that’ll bother me, but the overall package is much improved over the W213. IMHO. My goal is to purchase a CPO W214 2025 E53 AMG in 2027. I can wait patiently until then…
The Best of Mercedes & AMG




Most of the difference is from the sides views.

Unless you are on smooth pavement, with 21 inch wheels expect tire/wheel damage including bubbles and bent rims.
Hope this helps




There are several advantages to my set up vs. 20 inches: (at least for me, where I live and drive)
- Savings of $5000: The 20 inch wheels are $1950 extra and the air suspension $3200 (you do get the rear wheel steering which is an advantage)
- Tires: As I drive in winter for skiing I can do it on the all season tires that are stock on the 18 inch wheels. Traction in snow with 20 inch tires is not as good as 18 inch, and if they are summer tires, you have the extra expense of 4 winter tires.
- Where I live on Long Island, pot holes are a fact of life. I have already had to replace three tires at 20K miles, with at least 20K miles left on them because of bubbles. With 20 inch wheels I do not think I would be getting even 10K miles before they had to be replaced. (I would replace them at Costco with their 5 year road hazard warranty)
- Wheels: Again because of where I live, by necessity I would have to pay extra for the wheel package.
Just my $.02

I wonder if the smallest 20" build option (middle E53) is actually the smallest wheel that will fit over the AMG Performance Package composite brakes. Also wondering if just going down to 20" will make enough comfort difference (about 14-17% more sidewall going from 35/30 to 40/35). 20" also opens up all season tire options.
Wheels aside, the AMGs (bottom two) are definitely the most handsome in those images.

For me there is no choice: 40% of my driving is long distance on the Interstate: here I want as much comfort as possible: 18 inch wheels on the E450
The rest of my driving is local: I do not drag race or accelerate hard: the E53 would be completely wasted on me. I find the looks of the two, 450 vs. E53, too similar to warrant any extra money. Ditto for the interior.
But then again, I just turned 80, and I realize that that the market for the E53 is not me!
Good luck!

Suggest you test drive the 450 with stock 18 wheels and another car with larger wheels. See if the trade off in comfort warrants the extra handling and cost and further costs down the road when tires need to be replaced.
Also, three years from now, no one but you and other E53 owners will even know what the stock wheels were vs. the 21 inch wheels. Nor do the 21 inch wheels add any value on trade in and of course the replacement cost on the 20/21 is much higher and choices are limited.
What really gores me is the extra cost of the 20 and 21 inch vs, the 18 inch wheels. If you go to replace them the difference is less than $200 a wheel. But if you order the 20/21 wheel there is an extra charge of $2000. Mercedes is not giving you any credit for the stock 18 inch wheels.

My 2012 E350 had 18" wheels and were size 255/40R18 front and 265/35R18 rear. Doing the math to calculate sidewall height I had 3.86" (front) and 3.65" rear. The overall height of those tires are 25.72" front and 25.30" rear. I drove that car for just over 150K miles throughout TN and several road trips to NY, FL, and GA. Roads in TN are just as bad due to the freezing winter and our poor road repair. Plenty of cars on the side of the road with blown tires due to hitting a large pot hole. Over the course of 10 years and 150K miles, I have never had a flat tire due to a pot hole and have never been stranded due to a flat. I've had my share of nails or other objects puncturing the tire but I can easily fix them with a tire plug kit I keep in all my cars and motorcycles.
Moving on to the W214 model (and I would suspect is very similar for the wheels and tires on the W213) the tires are larger than on the W212. The below table show the sizes from the factory based on the different wheel choices and the tire size of my W212. Notice the tire height of the 2012 with 18" wheels is only 25.72 and 25.3 inches while all the sizes for the W214 are 2 or more inches larger in diameter. Because of this, the W214 with 20" wheels has the exact same sidewall height as the W212 with 18" wheels. The point of this is don't just go by the wheel size. There is more to the equation than just wheel size. The big factor in ride comfort is sidewall height and that is also a big factor in durability over pot holes or other road hazards. The key thing to look at in the below table is SW Height (in) or in (mm) if you prefer metric. The differences (last two columns) are in inches. If you go with the 18" wheels on the W214, you will get nearly 5" of sidewall. Move to the 19" wheels and you will drop about 0.5" of sidewall and drop 1" to go to the 20" wheels. The 21" wheels will drop the sidewall 1.5" over the 18" wheels but still less than a 0.5" drop from the W212 18" wheels.
If you are wondering how to calculate the above data, you can reference any number of online examples such as this one from Tire Rack.
