E300/350 vs E400/450 Power?












I have driven both: to me the 4 is "peppy but not powerful ": the 6 is smooth, quiet and powerful.
I had the same reaction when I had the 5 series BMW's. I also went to the 6 over the 4.
I also felt at this price point, the 6 is a much more appropriate for an E Class. Of course in Europe almost everyone drives a 4, but their trips are shorter and gas much more expensive.
As I lease, the monthly lease payment was about $100 a month extra for the 6 vs.4. Buying there is a much greater difference between the 6 and the 4, so keep that in mind.
Mileage: As a loaner my dealer has given me the GLC with the 4. In town I was getting about 25 mpg vs. 19/20 in my E450. So if most of your driving is local the 4 has an advantage. On the other hand if most of your driving is local the total mileage will not be that great to begin with so the extra mpg, may not be significant.
On the open road at 75 mph, I consistently get 30 mpg plus. At highway speeds the extra power of the 6 vs. the 4, I think eliminates most of the advantage of the 4.
So as others have posted, drive both, weigh the cost differences and then decide.

"Peppy" is the right word for the 4 - even in the GLE, it feels lively and responsive around town - less so when accelerating from 50 to 70mph on the highway - still adequate but not "fast." The start/stop functionality is less smooth on the smaller engine.
The V6 in the 450 (can't speak to new inline 6) just plain feels fast - it pulls strongly even 60 to 80mph and feels like there's plenty left. ( must be getting old because it felt like overkill for me ) Start stop is much less noticeable.
The effortless power of the 6 is definitely a luxury - but the 4 is still a good choice and it is by no means a punishment to drive every day.

I've never had any complaints about the "peppy"ness of my E-class. We're only a 1/4 mile or less from the interstate which is the primary way to town/shopping/meetings etc. The speed limit is 75 MPH on the interstate and I've never noticed any issues. My leadfoot days are past, but the driving on the highway is quite good by all measures. Both my brother-in-law and my nephew have driven the car and they both assumed it was rated around 300 HP. On the few occasions when I wanted to really hammer it, I switch to sport and I've been more than satisfied. BTW this is the same technique I used with the 6 cylinder BMW 328 coupe I had a few years ago.
Although it has been sometime since I had a 2005 E320 which had a v6 rated at 220+ HP and 232 ft lb torque, but this new car clearly performs better all around -- acceleration, passing, the ride -- than the W211. If the question is: Is more power better? The answer is yes. If the question is: Is the 4 pot strong enough? The answer is yes.

Ex Navy guy here (Engineer Nuclear Submarines) so won't steer a fellow service guy wrong.
Had many fast cars: Corvetts, Ford GT40, 427FE powered Shelby Cobra and of course the 2015 and now 2018 SL550 so I know what "performance" feels like.
My daily driver is the 2020 E350 replacing a 2017 E300 and prior to that lots of "E" class cars with a 6 cyl
For daily driving the 4 cyl E350 is great...I can easily enter highway traffic with no effort, pass slower moving cars no problem and great gas mileage.
Also the cost of ownership original and residual if lease is better with the 4 cyl. so for regular driving why want or need more?
Real proof is:
I have removed the trunk badges so no one knows it is a 4 cyl and surprising to me many of my friends and clients think it has a big engine; also as most MBs now look alike without the trunk badges many think it is an "S" class (not that I'm "posing" because I'm not badging as an "S" but, interesting how models look so much alike to many only the badging differentiates.
Bottom line is one should drive both. I do agree the 6 cyl is more powerful but, for my daily driver I don't see the advantage.....maybe if I only had 1 car I might get the 6 cyl but, really I'm so pleased with the 4 cyl performance I think not.
Performance of the engine and transmission combo was well thought out....AND...if you want a kick going to "sport" will liven things up !
Bottom line try them both BUT, do a real road test (highway and back roads) then try "sport" mode in BOTH settings.
Let us know what you think after your test drive and what you decide.

PS: If we want to compare MB models I/we have a 1986 560SL with 30K original miles (we bought new) and IT is the ultimate in a "solid feel"that we don't get today with any newer MB. It is "solid", doors close like a vault, and is "planted" when driving. MB really lost that "feel" with newer cars.
One more thing:
For 1'st time on an "E" class I went with the 'acoustic" package and I"M SOLD on it. Lot's less road noise AND really solid feel over bumps ect vs the car without it....in my opinion really worth it for the "FEEL" it affords the E




My SL has the TT V6 and is has all the power I need. I traded a C7 Corvette for it and admit that anything over 400 HP is unnecessary unless you live in Germany or like to drag race.
I'm actually more concerned about ride quality so I want to compare a Sport model and a Luxury model to see if there is a noticeable difference in ride quality and interior noise level.


Regardless of what you do heed my suggestion and order with the "acoustic" package. I am convinced this offers a substantial improvement to "ride quality" (sound deadening AND vibration/shock dampening).........side benefit some improvement in solar loading.
My E-class has same sound each time I start the car.

You buy a Mercedes for its ride and refinement. It is already one the quietest cars, if not the quietest mid size car you can buy.
I have the the E450 Luxury Styling with the standard 18 inch wheels. I do not have the acoustic package
On this board I have seen over and over again people complaining about ride and road noise - something that really surprises me. Turns out that those who complain almost always have the larger tires or sport suspension.
I am not saying that the acoustic package will not make the car quieter - what I am saying is that the incremental degree of quietness is not worth the cost.

If you live in a warm climate the accoustic comfort package is a must unless you want to install window film (repeatedly BTDT) that costs about as much. I can't imagine the engine noise levels of the 4 banger without the acoustic comfort package. With it the noise levels are still almost excessive. My E55 was much quieter. My neighbor's BMW cycle is quieter than my E300 when sitting in the driveway with the engine idling.
On a side note, I drove a Bentley “New” Flying Spur a few months ago and did not care for the ride of their air suspension as I thought it too billowy, for lack of a better term. That car sort of floated over the road. The wagon has none of that and really has a good road feeling, while still being very insulated from road imperfections.




Is the acoustic package still available?
