Hi Folks,

I been looking at a couple of 2010 W212 M156 E63s (RWD) and they seemed a bit off expectations.

In comparison to 2006/7 W211 M156 E63s (RWD) they seemed:

• Louder
• More snatchy and unsettled in the transmission (MCT vs torque converter maybe?)
• Missing the OMG top end pull - just smooth up there... (Do the W212's have THAT much more low end which disguises the old top end power band...?)

Are they just that much more refined that they could feel slower or have I just driven a couple of lemons?

Mods, apologies, I think I stuck this in the wrong forum initially.

Please feel free to close ^. My bad.

Are you comparing the m157 and m156 engines? Are you comparing rwd and awd platforms? Did you drive performance package e63's? So many variables here that you haven't discussed and therefore your questions are a bit open ended

I'm a bit confused by your post. Did you test drive a non turbo V8 E 63 and then back to back test drove a TwinTurbo V8 E 63?

Did you feel like the TwinTurbo V8 was slower than the non-turbo V8? By statistics in magazines and anecdotal reports and YouTube videos the W212 E63 m157 is definitely definitely not slower than the W211 E63 m156

And stock, the 2014+ e63S (awd) is faster off the line than the 2013 e63 with performance package ...a rwd drivetrain

Thanks Peter, the W211 E63 only had M156's right as per the 2010 W212? I have updated the OP to make it more clear.

Saw your revision to your original post and this now makes much more sense. You also have to consider that the newer model E 63 vehicles may need to have a TCU reset, as the transmission perhaps adapted to a less aggressive driving style. Also I take it you were driving each of these vehicles in sport mode and not comfort mode

The multi clutch transmission is definitely with some bugs in 2010 and not nearly as smooth as the torque converter 2006 two 2009 E63. However the multi clutch transmission should not ever slow down the vehicle compared to the torque converter version. I personally think the 2009 E63 is one of the best looking sedans I've ever seen in black

how long did you drive each car for? When driving a used or new car I always recommend at least a 20 minute drive in many driving conditions such as bumper-to-bumper and highway driving. You may have two bad examples in the more recent vehicles you drove and I strongly recommend you drive some more to compare.

Also consider this thread

It is more refined plus the speed isn't like huracan v Taurus here, they are somewhat comparable.

w211 were more reliable in my opinion than the w212 e63 amg m156.

Thanks guys, great info, yes I am going to go and have a look at some more W212s.

So if I could find a nice 2006/7 W211 that would be the preference over the 2010 W212? Was 2010 the first year they did MCT?

Otherwise should I spend a bit/quite a bit more on a post 2011 W212 to help get of the head bolt radar?

Just trying to figure out the sweet spot here.

Majority of people who buy the w212 m156 have no issues, and then theres the unlucky ones like me which it spends more time at the dealer getting repaired than being driven itself.
Id personally go with the w212 if i was you beautiful car to drive.

Before you make any purchase of an M156 engine based car you can ask the Mercedes dealership to look up the engine number and see if this qualifies for the head bolt problem, I personally would not touch a car that was in the head bolt range, nevertheless most people will be just fine, but when there is a problem it is usually catastrophic

As you probably know, Mercedes will not replace the head bolts prophylactically if there is not an active problem, they are cheapskates like that

I've ridden/driven both...they're as slow as each other tbh. OMG factor kicks in at the top of each gear...so from 80-95mph in third...from 120-140mph in fourth. I wish this motor had a stronger midrange.

No 7 went on my 2008, took the top half of the engine with it just over year ago. No warning at all. Lovely being outside of warranty. Have to admit I drove it hard for multiple years, was close to 100k miles. Loved that engine...

PeterUbers

And it's stories like this that make me make the recommendation that I make as per above ....

Missionary

That is interesting and enlightening. So if these cars felt flat on the top end then there is defo something wrong. They were both Japanese models...

I'll drive some more and update.

Yeah it's a notably better surge at the top of each gear. It's almost like VTEC valve lift, but without the actual change in cam profile.
