E300 vs E350
It confuses me that the M264 engine starts just with 181hp, 258hp then up to 299hp/370N.m. Is there any real performance gains / durability issues regarding the 299 version in the E350. There is around 5k$ difference here in price and I am inclined towards the E350 but I am afraid of durability issues. Any one can spot some lights ?

2018 E300 4Matic Sport
I can't speak to the mechanical aspects, dependability, etc. However, having had an E350 4Matic (which I think was a 6 cylinder) and now an E300 4Matic (turbo, 4 cylinder) -- and I will attach a big disclaimer to what I am about to say -- I do not drive fast, aggressive, look to enjoy the performance of what the car can do, etc. -- I don't have a problem with the smaller, E300 engine. I drive nice and easy, but the car can accelerate, can be relatively nimble, and can move as much as I need and want it to. I did not know the E350 engine had issues. Sure, my E300 is a pretty big car, and it is a 4 cylinder, so that could be an issue for real driving enthusiasts, but it is not for me. I am sure some of the resident experts who are very knowledgeable about this can speak to this more than I can. Whichever car you end up getting -- good luck and all the best with it!

Depends on where you live. If you live anywhere other than North America (USA and Canada) then the E350 has a 48V mild hybrid system, if you live in North America, the E350 is just pure marketing, it uses the same set up as the W205 C300 facelift, reason why they called it E350 because they don't want it to sound like it is the same as the C300. To answer your question, the real performance gain is that the turbo doesn't have to spool up with the mild hybrid system so quicker acceleration, durability wise I guess the engine doesn't have to work as hard (again, this only applies to E350 outside of North America)

Yes it is non US, and we got both with 2.0 engine for the E350/CLS350 with 299hp and the E300 with 258hp. I am thinking that 258hp from a 2.0 engine is already too stressful. So what it would be like to get 299 out of it. And yes the E350 does have a 48V system but that is another issue as it is a novelty and I am not aware of its durability and repair costs. Thanks

E350e
I have 2018 E350 e PHEV, the engine is indeed M274 with 211 HP / 155kW. I can't really say what is the difference with E300 non hybrid as we only have E250 here as other option and it also has 155kW/211 Hp power.
I have read for the EQ boost model the total power is 210 kW (155 + 55), but on my car the registered power in the official paper is only 155 kW.

Definitely a different discussion here in Europe. In my country the speed limit is 140 km/h (87 mph), in many countries it's 130 km/h (around 81 mph) and I regularly drive through Germany, where many parts have no speed limit. A stronger engine comes in handy.
