That's a very strange calculation method. In the case of the GLE450e, the car would have a very different rating based on ICE only and ICE/Battery combination.

 

I think the GLE 450e powertrain is more sophisticated than the scenarios being discussed.

While it has a finite range of pure EV, after the battery range reaches 0 it does not mean the battery is depleted.

It means pure EV is not available but the vehicle can operate as a Hybrid combination of ICE and Electric, but unlike a typical hybrid it has a larger electric motor and available battery capacity.

The long range battery will retain a reserve charge of 10 - 20% for hybrid usage which is 3 - 6 Kwh.

The battery does not recharge from the ICE but does from braking or slowing.

So I expect it is available for significant amount of extended assist but not continuous for miles on end.

Bottom line is if pushing the limits of towing capacity is the goal then it cannot replace a 6 or 8 cyl ICE. But it should perform well for medium duty demands, better than a GLE 350

 

It is strange, but there's a bunch of Euro things that I won't really understand either.

But that's the way they establish tow ratings, and it doesn't make any difference whether it's electric, gas or pedal powered.

Maybe with the Advent of new drivetrain technologies, they have separate rating schemes.

 

I too have a 2024 GLE 450e. 18,500 miles over 22 months with no problems and great EV mileage of 62 miles per charge. BUT THEN ... the EV battery died: on a full charge, the battery's predictive mileage is reflective of what is happening outside the car. Then as the battery discharges to about 50% and shows 32 miles left -- the battery collapses and I get only 7 miles on that last half of the charge. Repeatedly, for me and for the dealer's service techs. So, at 19,000 miles and 22 months, they are replacing the EV battery. Now, this car is assembled in Alabama and I live next door in Florida. But the battery has to come from Germany and it will take "weeks", per the dealer. I wrote a review for this forum after I had the car for 2 months and gave it all-thumbs-up but for some minor quibbles like the fake exhaust ports. Now, however, the failure of the EV battery and the totally ridiculous supply chain for its replacement cause me to question whether PHEV technology, as Mercedes conceives it, is up to the demands of the real world. I do recognize two factors: MB has used basically the same PHEV setup on some European vehicles for years, so they should have a pretty good grip on the technology. Second, the fact that my replacement battery has to come from Germany MIGHT mean that the failure of my battery might be anomalous -- if, say, 1 out of 5 batteries were failing, they probably would have a supply to. deploy from the US factory. ANYWAY, my EV range for now (and for the upcoming "weeks" ) is about 35 miles, which would be great for a cheaper PHEV, but obviously is not what I paid for. I leased this car because I did not fully trust the long-term value of this hi-tech vehicle and, at least for now, I'm glad I did not buy it outright. I'll repost once this is all resolved.

 

A buddy bought a Malibu ski boat this summer. After a month the GM based engine blew a cylinder and needed to be replaced. That boat is twice the cost of your GLE. I can guarantee that’s not what he paid for. But @hit happens.

Why not talk about the wonderful resilience of your PHEV that still gets 35 mi on a failed battery and has an ICE engine to drive you anywhere you want to go while waiting for delivery of the new battery.

 

A customer who has been sold on a product, based on claims and features, quality, what have you, is totally justified in expecting that all claims be met in ownership. They should not be expected to be content with anything less than as advertised.

 

I would agree with you if Mercedes refused to replace the failed battery. But Mercedes has agreed to replace the battery. There is no car which has perfect quality. That is why each new Mercedes comes with a warranty, as advertised.

 

I have to agree that **** happens, and nothing is perfect.

 

I forget the right number, but the GLE450E without elcct is about seven or eight hp lower than a GLE 350 and weights quite a bit more. GLE450e sold to my neighbor a long time ago. He drives locally a LOT more than I do. I've a '18 S560 Coupe with a 21.1 gal tank that gets 28 mpg on Interstate hwys doing a slow 75 mph to Big Spring, Tx from Ft Worth, Tx. Drove from Ruidoso, NM to Ft Worth on one tank, a bit over 500 miles on a single tank. I do not like to stop when going from one place to another, period. I care not about visitiing gas stations when it's not a requiement, I do not hate oil companies at all. I do hate the EPA giving out incorrect information on EV cars though. A Tesla S Model, as an example will NOT go any 410 miles on a interstate hwy at posted 75 mph speeds It does about 80% of 410 miiles and there'd better be a Supercharger at 320 miles or else. I'm not including the GLE 450e as having it's EV range alone being wrong on EPA ratings, Not at all Just those False claims of a EPA range of a EV going over 300 whatever miles on an interstate, I trust Car and driver onine mag for true hwy milage on an EV. EPA has be deliberatley deceptive on EV ranges for way too long, Corruption in spades imho, Time from Petaluma Ca to FT Worth in 24hrs or a bit less is my way of traveling. Not stopping to feed my face and car allllll the time.

 

I really don't understand your point.

The ICE in a 450e is rated 248hp. The 350 is rated 255 hp was a mild hybrid. But that does not take I to account that the 450e when the battery range is used up is still a full hybrid with a larger electric motor than a mild hybrid.

The rated range of the 450e in electric mode is 48 miles. I get more like 57 miles in the summer. The gas range is 412 miles. The combined 460 miles is over 7 hours of hwy driving.

So what's the problem?
