E400 Coupe - 3 litre v 3.5 litre engine

[DavE400]

Hi can anyone advise.

I have a 3l V6 2014 E400 AMG sport plus and spotted a 2015 E400 AMG line coupe that sparked my interest

The AMG Line apparently has a 3,5 litre V6 engine but both cars have the same bhp and performance stats.

Trying to understand the benefits of the 3.5 litre engine......

Thanks in advance

It'll be a typo, that will have the same engine as your existing car. 3.0 Twin Turbo.

Not sure to be honest - as there must be a lot of typos on various web sites -

Sounds like they brought out a 3.5 version towards the end of the life of that model:

You can compare the stats between the 3.5 and 3.0 on that site to see what the differences are, if any.

Interestingly I found it mentioned in this Brochure:-

http://tools.mercedes-benz.co.uk/current/passenger-cars/e-brochures/e-class-coupe-cabriolet.pdf

But I can't find any reference to an engine code.

It has identical performance figures to the 3.0 v6 with a 333hp output.

Changed to 3.5 from 3.0 around late 2014 iirc.

Only in the E coupe? Not used in any other model with a 400 or 450 designation. Seems odd that MB would use an engine in one model only.

I guess it's one for the ask JBD thread.

E400 AMG sport plus insurance group 45 but E400 AMG line coupe insurance group 42 ....so the extra 0.5 litre of engine reduces insurance ............bizarre!

BenzBoost - Mercedes introduces a new 3.5 liter M276 turbo variant with the same horsepower and torque - M276 DELA 35 V6, 333 horsepower 354 lb-ft of torque

It seems to have made it's way into the CLS400 as well and it must be an emission thing for certain markets as mentioned on the ask JBD thread.

It runs much less boost to generate the same 333ps so you'd assume it would hold plenty of tuning headroom if you were that way inclined.

Delivers torque lower down too which is welcome.

Here's an article from when it was introduced into the CLS.

Interestingly it seems that the new E400 coupe has reverted to the 3.0 V6.

When I bought my E400 I drove both versions and not surprisingly couldn't tell the difference.

I am impressed by the thrust and smoothness of the 3 litre bi turbo V6 in my SL400 .. it sounds very dull though.

Yes it certainly has plenty of go, the sound is quite monotone though.

More goodies with the E400 as standard plus a little faster 0-62.

But much worse fuel economy and the old 7 speed gearbox where as the E350 3ltr has the new 9 speed box ....silky smooth
