Hey guys,

I just ordered a 2018 Coupe! Delivery is estimated for mid to late April. Can't wait!

Nice! Any plans for it?

As far as modifications? Maybe some black rim savers to cover up that silver ring like this guy did. Also curious about the piggyback. Not sure exactly what that is, need to do a bit more research.

Really excited to drive it. Coming from a little VW Golf, this is a huge power and luxury upgrade.

Piggyback is a serious waste of money. If anything, get a full software upgrade. Check into AMR Performance. I have their stage 1 and it is ridiculous haha I love it.

That's a pretty hefty price tag.
How does this affect factory warranty? Void?

Piggybacks are useles. I am AMR stage 1 as well and it is well worth the investment. I believe they are giving killer deals on tunes currently as well for the holidays!

Congrats! It's a great car, I'm one year in and I love the thing.

Good news everyone! My vehicle "now has an estimated delivery date of late March (possibly earlier)."

Sandsnip3r the piggyback from Burger is great for what it is. For the price point you cant go wrong. All depends on what you want and what your looking to spend.

2018

Just got my 2018 c43 coupe last week and LOVE IT!
Have a question regarding the recommended break in period of 1000 miles.
The operating manual recommends using Comfort mode during this period. The problem I have with this is that I am constantly forced to manually paddle the auto gear selection down as the tranny
goes to 9th gear by 40 mph! This puts the revs at about 1500 rpm so I am constantly having to manually downshift to get the revs in the 2000-3000 range.

I made the executive decision to start in Sport mode instead of comfort which still goes to 7th gear by 45 mph and 2000 rpm but thats better then 9th gear at 1500. I also am able to avoid having to
CONSTANTLY downshift to avoid ******* the engine.

Any comments or suggestions would be appreciated.

Thanks for sharing that problem. I'll be accepting my delivery early March so that'll be good to know. Pretty ridiculous 9th at 1500!

That sounds like an optimistic delivery time . My C43 cabrio was ordered in early December last year and estimated delivery is mid April and my current 2014 C350 took 5 months to arrive !

ANY INPUTS STILL APPRECIATED!!!!!!

General consensus is that only "real AMGs" need the break-in period. Since the 43's engine comes from an assembly line, extremists don't call it a real AMG. And, in the manual, the break-in period is only for, what they call, "Mercedes-AMG Vehicles."

You are incorrect about the manual, I just got it with my new C43 coupe delivery last week. The manual is written/titled for "all 2018 C300 coupes" The break-in section is written for all mods and recommends using
E for all "non-AMG" cars for first 1000 miles and C for AMG cars. Hence my question. In C mode, the car hits 9th gear at about 40-45 mph and only goes to about 1500 rpm.

I detect a sense of sarcasm in your remark about "extremists" only considering the 63 as a "true AMG" vehicle. I test drove both the 43 and 63 coups before making my order decision. The 43 coupe has PLENTY of ZIP and I really saw no need to spend the extra money for a track ready 63. This is a personal choice and I am completely thrilled with my new C43 coupe. It is looks great, sounds great, and handles great.
I would have made the same decision again opting for it vs. the crazy tight and firebreathing 63. To me, that car is more for people who at least occasionally track it which I have no interest in. I could easily of afforded either mod but didn't see the need to go with the 63.
As I try to nurse my baby up to 1000 miles, I do put it in S mode at times and can tell again what its true potential is It is indeed a great, very quick vehicle. Enjoy it!!
BTW, I got a great deal on it for a custom order and only added wood trim and perf exhaust. Net price about $54K plus tax/fees. It comes with a ton of great standard features so I didnt load it up.. I try to do that every time I itch for a new vehicle. Let the "extremist" 63 owners try to come close to that price.
I am not dissing the 63, it is a great monster of a car, but not necessary for my desired use and needs. I'll keep my awesome 43 coupe

@uzona, I would question why you need the revs in that range. Let the car decide. If you need to change down, pull on the left lever on the steering wheel the car will select the correct gear then mash the accelerator. About the C63 v C43, that's beating on a dead horse. Don't rise to that bait. Enjoy your motor and don't drive it like you nicked it...

Well that is not what the AMG techs at my dealership said...they HIGHLY recommended a proper break in period (1500km...metric in Canada) for a C43. Involving not putting it into Sport or Sport Plus.....keep revs below 4000 RPM...and do not use cruise control or drive extended long periods at a constant RPM.
Just because an engine was made on a assembly line does not mean the build tolerances were sacrificed in comparison to a hand-built version.
Here is a published quote from a Mercedes representative

Mercedes-Benz knows a thing or two about performance engines as well. Their Manager of Technical Service, Literature and ISO is Sylvain Gilbert. He explains what goes on inside an engine during break in.“Modern manufacturing technologies can precisely cut, polish and hone materials at exact dimensions, with tight tolerances,” said Gilbert. “However, at a microscopic level, metal surfaces that appear perfectly smooth can actually still be rough. During break-in, the peaks of the microscopically rough metal surface get shaved off and flushed away, so the surfaces smooth out and glide with less resistance.”

The standard Mercedes-Benz break-in for gas and diesel engines recommends driving at varying engine speeds for 1,500 kilometres while keeping the revs below 4,000.

After this point, customers can gradually increase engine speed and load to the permissible maximum.

When it comes to breaking in the brand’s high-performance AMG engines, Gilbert says procedures are virtually the same, but with a few additional stipulations.

These include keeping the vehicle speed below 140 km/h, and ensuring the engine is at operating temperature before being driven at higher RPMs.

The specially-designed AMG engines take higher loads into account, using special materials and parts to handle additional stresses of performance driving.

“Optimal engine performance and fuel consumption are only reached after the break-in period is complete. Power actually varies a little over engine life, it actually raises within the first few hundred kilometres,” Gilbert added.
