M156 vs m157 amg engines c63 e63 amg

[rsk21]

Having recently moved from a C63 to a CLS63 SB I can say that there is a definite and very noticeable difference between the two. At first blush the BiTurbo was disappointing lacking both the bite and the bark of the n/a engine. Where it comes in to its own is the torque and having completed my first long mway drive last night I found the biturbo a more relaxing car for such a journey.

On order to restore some of the aural excitement and get a bit of the madness of the C63 back I've invested in new pipe work (see thread elsewhere) which IMO has made a big difference. I've obviously had to adapt my driving style a bit given the comparative lack of revs and I still think the throttle response lags the C. On occasion I can push the pedal and nothing happens at all, am wondering if this is a facet of the learning gearbox ?

Do you drive it in C or one of the S modes?

In mine (an M156) the C (controlled efficiency) is quite lethargic, with 2nd gear starts. S modes and manual are significantly more sprightly.

I use c on motorway trips, m everywhere else when up to speed.

The issue seems to be when moving from or in neutral.

I can't get my head round M mode so just leave mine in S which is quick enough for me and lets me keep my concentration on the driving.

Much more point and squirt fun in M, though I think M in a 212 is different to M in a 211 - I recall that a 211 will still change up automatically, whereas in a 212 it disnae - the dash turns red and the engine cuts a couple of cylinders for protection. There's also no kickdown - you have to do the work, which is fun.

Also there's no tip function on the gearshift on a 212 - in M it's paddles or nothing.

Too many numbers going on here lads :

Whats 156 v 157 ?
Whats 211 v 212 ?

Im assuming something to do with 6.2 v 5.5 TT ??

M156 - 6.2l naturally aspirated (your C63 engine)
M157 - 5.5l twin turbo (in the E63S amongst others).

211 E Class from c2003 to 2009
212 E Class from c2009 to present

W = saloon
S = Estate.

It doesn't change up automatically in M mode on mine either and the cirlce in the dash goes red and demands you to change up whilst also cutting power.

I remember it when I test drove one at a dealer and had it in M mode but never tried it on mine as it's far too much work for my head to take in.

Unlike a proper manual you know what gear you are in, in the AMG you don't and have to look down.

also in S mode you can just hold down the left paddle and it will drop as many gears as is safe and off you go then you are in M/S mode as it will stay in the gear you choose and you go up the gears using paddles or you can hold the right paddle and it will then go back into S mode.

Thanks - I didn't know that .

Actually I wish it did change up in manual - I quite often hit the rev limiter, quite annoying.

Interesting thread his...

Agree the 'M157 is a torque monster, would prefer M157 but not available due to tree huggers.....

M doesn't shift up it just crashes into to limter in second and third uless you pull 'up' by 4k as the box is so slow.

I love short shifting in M and riding the torque with the engine thundering away from 2k to 4k.

If you have a 2014 E63 it will have the M157 5.5 biturbo

Sorry, I know that, what I meant was I would have preferred the M156 but it's not in the e class anymore....

 

[c_200k]

I've not drove the W212 E63 with the 6.2l M156 but with the better gearbox and other upgrades I can only imagine it being perfect. The 7g box in the w211 is a joke at times and has its own mind too clumsy for my liking but the remap has made it a bit more acceptable.

 

[doughboy]

I've got the 7g MCT in my W212 E63 with the 5.5TT, it's a great cruising gearbox, but pretty rubbish when pressing on (as all auto's are), the usual problems, wrong gear wrong time, lurching slurry down shifts, upsetting kickdowns right in mid corner or just when you're crossing a slippy white line etc.

In Manual you can avoid the unexpected down shifts and preselect properly before overtaking etc, but then in M it's so slow to respond you have select a gear 2000rpm in advance to avoid lumping the limiter.

And who's idea was it to remove the manual up/down from the selector stick? Now you can only shift from the stupid steering wheel mounted buttons, impossible when you've got any lock on.

Why can't we have proper shift levers fixed mounted on the steering column, much better than silly playstation-flappy-paddles.

Question asked was, is it a good time to buy a c63 -

Hi I am going to say yes as well. The new E63 (turbo) does not have the same noise, excitement and character of the older one, and I fear that the next C63 will be the same. Get one while you can....I am totally smitten over mine and I have had it for quite some time.

A Separate reply - the n/a e63 was fantastic ,I was a bit disappointed with the new engines,there is combined with the slightly sluggish gearbox a noticeable lag when you put your foot down I found compared to the n/a version.


One more -


Totally fell for it (c63) and if I was in a position to need to run my own car again it'd be a strong consideration.

Also ran an E63S recently but while the interior is better the 5.5 twin turbo isn't even close to how raucous the 6.2 is and doesn't have the same presence with an unflaired bonnet and 'sensible' estate and saloon guises.

I've been in two tuned M157 engines during the last week - E63 and CL63 (claimed at 570/630bhp respectively) both times as a passenger (which I realise will make the experience different).

My technical observation of the performance on offer from both was...

F*ckin 'ell .

Which, of course, is good news for the future, if you're planning to have one, as I am.

Neither sounded like mine though .

Edit - I should add, I'll be owning one through evolution, not necessarily through choice, as the monumental M156 will be gone soon .

Agree

I had a c63 for a year before swapping to the m157. Both boxes are a bit lax in my opinion but I agree with F*ckin ell.

My SL was putting out around the 575bhp mark originally and there was a slight hesitation at low spreads before the turbos kicked in then ..... Now it has had the power an torque upped the lag has gone and it's ballistic. Tcu next to sort the box out and then I don't think I can fault it. They are quieter at lower revs than the n/a engines but mine puts out 99db at just under 4k revs but sounds monumental under full acceleration.

Went to look at a new E63 estate yesterday in Swindon - who now have AMG status ( fair enough but they need to read up a bit more!). I must say it looked great in Tenorite with the black 19's. I can see it being my next car. Want the S but no way is it worth 10k over the standard.
I still haven't driven an M157 yet though. Been in one yes, but the passenger experience is SO different. Even my C feels totally different as a passenger!
They are having an AMG event soon so I will take advantage of that.

 

[doughboy]

By a non S model, save 10grand, then spend £1K on a plug in tuner box to give you 600-630bhp

And then you can sell the tuner box when you're done...
