Turbo lag on 350 vs 450
Don’t know where the guy who popped up with the mis-information that the X5 can be optioned with a 4-cylinder, disappeared, with no follow-up from his end.
Bottomline, IMO, MB should not equip the GLE with their 4-cylinder engine. It is an inappropriate pairing. Another inappropriate pairing is MB equipping the 4-cylinder GLEs with their 315/325mm wide tires on 21/22 rims, which is akin to a normal portly guy walking around with a jacket saying he’s Mr.Olympia. Humor inducing, at best.
For the GLE, the 6-cylinder with mild-hybrid, should be the base engine. The 4-cylinder is however a great pairing for the smaller/lighter MB SUVs like the GLA/GLC/GLB etc. Hope MB does the right thing.

In my view, having owned multiple loaded spec BMW-s and now having received my first MB, a fully loaded GLE 450 petrol, the interior quality is a disappointment and shows the manufacturer clearly cutting corners. The car excels in ride quality, sound dampening, size/practicality, stereo but lacks heavily in leather/seat quality and dashboard materials (cheap scratchy plastic found in many places. When fully loaded, the X5 interior is just a very nice place to be in and the diamond-stiched comfort nappa leather seats that BMW has is a level above MB even when considering the AMG GLE models.
IMHO the only MB models keeping up with their quality standards are currently S class and G-wagon

P.S. Dont get me wrong, the current GLE is a great car and a successful model, at the same time at this price point I would not expect to find any costcutting or compromises made.

When I was purchasing my GLE450, I saw the GLE450e, which intrigued me, since that in my mind, was the best of both worlds. All of the good aspects of the Inline-6, with electrification added in. I then dug in deeper, and realized that the “450e” was really a “350e” (a 350 4-cyl engine with the plug-in stuff added in). I dropped that plan right away.

I'm right here. I "liked" your clarifying response because I learned something from your post.
Thanks for the clarification. Yes, 4 cyl. No, not in this market. And it's only @$4k more than the 350.
The 2 liter GLE 350 is plenty of engine for many, and it fits a niche in the MB lineup.
With all the regulations, owners don't have many ways to customize their cars, so staggered tires is one way. Wraps are another.
You don't have to be fat to drive a four cylinder.
I prefer the 450 for the reasons I posted earlier. I drive a 53, after owning a 450. I lost 8-10mpg, BTW.
They've had some great sixes. BMW leather smells funny to me, and their handling is just lazy.
I keep wanting to like them, having sold them in the 80's and being friends with the Dealer, but I just don't.

cost cutting is another thing. I was shocked to find out that the rear seats are not heated. That the rear climate package doesn’t include heated rear seats. Also, side rear window shades, not there. My MDX and Audi Q5 both had them. They were manual, (what a hardship) but they were there. I couldn’t believe that one. Cost cutting has been around for years. I had a 2004 Saab. Then a 2007 Saab. Stuff that was standard on the 04 were no longer available on the 07. I don’t like the cost cutting but, it’s not going away.

The Best of Mercedes & AMG
Let's not forget the C 63 S E Performance the fact they used the C 63 S name was also because of marketing.
Currently, the GLE350 has a 2.0L 4-cylinder turbo engine, which means the "350" is a meaningless, pretend number that tries to project something it is not. Same with the GLE450, where the "450" is intended to be a 4.5L V8, while in reality, it is a 3.0L I-6 Turbo.
Some say that since it is a turbo engine, the performance is "similar" to that of a 3.5L V6, and that's why it is called a "350" etc., but I don't buy that kind of trickery. Just say it is a 4-cyl and be done with it, as far as I am concerned.

The old rules of physics start rearing their head, when you pair such an engine with a 5000+lbs vehicle. As stated above, BMW's base engine for their X5, is the 3.0L Inline-6 Turbo. Their X5 PHEV is paired with the 3.0L I-6 Turbo and the electric bits.
I am sure the 2.0L performs "adequately enough", given what it is being asked to do. But I just wish MB had done the right thing, just like BMW, and gone with the I-6 Turbo, for the GLE.
PS: I used to have a 2002 Subaru WRX, back in the day, with a 2.0L Turbo engine (227HP/217Torque). And paired with a vehicle with a curb-weight of 3085 lbs, the thing was a hoot to drive, despite the noticeable rubber-band like turbo-lag. It was another one of my cars that went well above 200K miles with zero problems, and I used to personally change its oil every 5K miles. I have owned far more expensive cars since then, but I still miss that little car even now.

Aren't you driving an I6 GLE?
I'm not clear on your objection. Clearly MB offers such a thing. No buck teeth or Chris Bangle, though.
PS: My GLE leaves WRX's in the dust at the track. Road course or drag. If you love boost and lag, though, WRX's are stellar. For the Traffic Light Racers out there.




As MB announced when they made the "Almost All In" switch to EV's, their offerings will be "according to Market Conditions.
With a new US administration and China's economy fumbling, those Market Conditions might be leading us to more cylinders.
In the meantime, a near-500hp 2 liter four is pretty impressive.
Looking at this Copilot output, it's clear that the entry 350 is designed to make more money than the rest of the lineup while also providing a lower barrier ($$$) of entry to the GLE. I am actually surprised BMW doesn't have a 4 cylinder option (sDrive30i) priced at $59.5k to compete with the 350.
Edit: added power-to-weight ratio.

The reference above is entirely about the lower-down GLE350 (or the GLE450e), where the 5000+lbs vehicles has been equipped with the 4-cylinder by MB, unlike competitors like BMW who equip their BASE X5 with their I-6 and not their I-4. And BMW equips their regular PHEV also, with an I-6.
And what WRXs are you referring to ? I was talking about my WRX from 22 years back. Not something from the past couple of DECADES. I have not driven any of the WRXs in 10+ years, but I doubt they weigh 3085 lbs or have the kind of seats that the original WRX came with, or have the steering feel that the prior hydraulic system that the one I drove, had.

Your personal dislike for 4 cyl is acknowledged. Acknowledged. Acknowledged.
IMO the GLE350 (4 cyl) is a reasonable entry level application of their four, in their hottest selling model. I spent 1,000 miles / 10 days in one as a loaner, and my only complaints were turbo lag (pre e-Boost) which I easily adapted to, and passing power above 80mph at 7,000 ft elevation. No lag once moving.
I didn't examine the WRX seats at the track. The cars weren't fast on the straights or the corners. Late models with all their snazziness. For a certain buyer who isn't me.
My Mom had an H-6 Subaru. I drove it over Vail Pass and it barely maintained 45mph with four aboard. But it had a six! For another buyer who isn't me.

- Why does BMW not offer a competitor to the 350's 4-cylinder?
- Why does BMW not offer a GLE 53 competitor?
- Why does Mercedes-Benz not offer a 450 without 4MATIC?
- Why did Mercedes-Benz choose to mate their PHEV 450e with a 4-cylinder instead of an inline-6? Is it price? They would probably have to charge $5-10k more to justify the added two cylinders. Maybe they did a market study and found that potential owners don't care about 0-60 times and instead just want to reduce their gas and purchase costs?

Those sport seats in the 2001/2002 WRX (essentially Japanese spec sport-seats) disappeared in 2003 and no Subaru since, has gotten it back. No iteration of the higher performance WRX STI that ever appeared in the US, has gotten a decent sport seat (other market STIs get full Recaro seats as an option, while the US market gets a weak partial Recaro). So if you go examine the current WRX seats, you will no longer find what I am talking about.
The point however, is NOT about the WRX. The point is about the 5000+lbs GLE, with a similar 2.0L Turbo 4-cylinder that the 3085lbs WRX had 2 DECADES back. Does the point now make sense ?
Either way, my last post on this topic. The point has been repeated ad nauseum.
