So my c300 doesn't have the EQ boost logo above the power and charge does that mean my car didn't come with it ?

 

Do the Power and Charge segments light up when you drive? I thought they all came with it standard.

 

Yeah they do

 

Maybe some weird marketing thing in your area, where some other company has rights to EQ?

 

Yes all W206 C 300 with the M254 has EQ boost, they got rid of that logo on newer model years as they are considering dropping the EQ branding on all MBs eventually. This is nothing new. I think they got rid of the logo starting 2023 or 2024 model year in the instrument cluster.

 

yeah makes sense because my friends 2022 has the logo while mine doesn't but he also has a screen that shows him how much the battery is charged and i don't why is that

 

normal and intentional change.

 

They will not drop the branding. EQ will just be reserved for electric cars (like in "CLA with EQ technology"). They didn't want people to confuse EQ boost with "EQ technology", so fully electric.

 

We discussed this in one of the EQS thread, I forgot which thread but they are planning to drop the EQ branding eventually, next S Class EV will simply call it S class. So far they called the new MB g wagen the G580 with EQ Technology instead of previously trademarked EQG, so it takes time.

 

EQ Boost was MB's designation for its mild hybrid technology. Like most other car manufacturers, MB is not promoting MH technology as some glorious owner benefitting feature because of its unreliabilty, its circumstantial fuel savings, its ability to cripple normal operation of the vehicle and its integration with auto start/stop. Quite the contrary, MH is buried somewhere in the OM, and dealer policy is don't ask/don't tell.

 

Mhmm, although forum members been talking about the "EQ" branding as a whole to be eventually dropped mild hybrid or fully electric doesn't matter because that branding nomenclature will be gone.

 

Interesting. Right now they are just ontriducing this branding. It is used in brand new CLA. So why would they use branding they want to ditch?
I mean i assume they will want to ditch this naming once they go fully electric (which, unfortunately, probably will happen eventually), but for now they need to differentiate electric cars somehow.

WHAT?!
Most car manufacturers do promote MH, but it's not on top of their priorities, as they benefit much more from BEV and PHEV (emmissions regulations).
What about unreliability? Of course, probably failures happen, but personally never heard of any failures amongst people i know, not to mention any mass failures. It's actually rather simple tech.
How is it "cirppling" operation of the vehicle? How is it crippling integration with start&stop? It actually makes this system work perfectly for the first time ever. I used to always disable S&S in my older cars, without MHEV. W206 is my second car with MHEV and i never disable it now. It actually brings fuel savings when driving in congested cities with a lot of traffic jams and/or traffic lights.
Also if done right, MHEV can bring some benefit by helping to reduce/eliminate turba lag, and this is actually the case in MB. With it's 200Nm of torque, this small electric motor helps with turbo lag and acceleration at low speeds.

 

The branding is proposed to be gone the year the first fully electric S class comes out. We will see if that will be true. That is 2030?

 

I feel the same way about start/stop on the W206; with motor/generator, it just works so seamlessly. The systems have really come a long way from early attempts with conventional starters, where the delay in re-lighting, noise of pinion/ring gears, and vibration on startup and shutdown made me reach for the disable button every time. I'm sure there have been a few failures, but like a lot of internet forums, the bad experiences of a few get amplified and suddenly the issue is a "fatal flaw." It's just that the bazillions of other owners for which the system works perfectly never weigh in.

I do love the fuel economy of the C300, which is my cushy ride for errands and transport to golf courses a couple times a week. While I'm not exactly a hyper-miler, I do like to call up the trip computer and see what numbers I get for a particular trip. Personal best door-to-door is 38.4 mpg on a 30-mile trip, primarily freeway at 70-75 mph, super impressive for a big 3800-lb sedan. With previous cars (non stop/start) I'd do the same, but so depressing to achieve good mileage only to see the number on the computer slowly worsen when stuck at a 3-minute light.

 

I have no issues with the start/stop - as you observe it's almost unnoticeable. We do turn it off occasionally when we're in traffic and it's hot outside, just to keep the a/c running. As far as mileage goes, we regularly get 30MPG+ around town, and often 36+ on the highway. And also yes, we love the cushy ride, especially after we got rid of the abysmal run flat tires, which also made the ride very, very quiet!

 

Walk into any dealer showroom -- you won't find placards sitting on the hoods heralding "Now with fuel savings mild hybrid technology!" "EQ Boost"? IMO this implies a supplementary system that is non-essential to the vehicle. Yet if you search the forum and read about the experiences of those who have had mild hybrid system failures, they describe their vehicle entering "limp mode", requiring flat-bedding to the dealer to await replacement parts to arrive from Germany.

Conceptually, the mild hybrid system is simple -- an electric machine that can function as either a motor or a generator, and a battery that either delivers power in the motor mode or is recharged in the generator mode. In practice, it becomes much more complicated with the use of lithium battery technology, the battery management system, battery temperature stabilization, and managing motor versus generator modes. Automobiles have functioned for 100 years without mild hybrid technology, yet now a vehicle having MH stops almost dead in its tracks when something goes amiss with the 48 volt battery or with a motor that outputs a puny dozen horsepower (and only when accelerating from a standstill). Although faults may be few, why is the vehicle designed to go immediately into limp mode? Why can't an indication be provided warning of the fault and advising you that you have 100 miles to get to the dealer for repairs before limp mode occurs?

Turbo lag -- is this what occurs because auto start/stops shuts off the engine? If a dozen extra hp makes a huge difference, a tuning chip can deliver this, rather than resorting to a complicated and expensive mild hybrid system.

The second generation mild hybrid implementation with the ISG built into the transmission, should make the auto start/stop function smoother and less objectionable. And for those who drive daily in freeway stop-and-go traffic, there are likely measurable fuel savings. But I remain unenthusiastic about mild hybrid technology, as it would deliver nothing of value to me, while presenting just yet another system that will eventually malfunction and cost big bucks to remedy once out of warranty, and create potential repair inconveniences during warranty period.

We are fortunate to have choices about what we drive. None of my vehicles are MH equipped, and I'm happy with them as they are. Others are EQ enthusiasts and are able to purchase/lease whatever version of EV powering they wish. I'm not saying MHs, and EVs in general, are good or bad -- merely that they aren't for everyone.

 

The fact, that there are no big signs, doesn't mean they are not promoting it. It's there in almost every MB car for a reason.
But of course marketing is focused on EV's and PHEV's, as this brings significant benefits for companies in Europe ("fleet emmissions" and penalties for going above 95g/km of CO2).
I don't know why it's going to a limp mode. You would have to ask MB. There's probably some reason for it, but i don't know what it is.
Of course there are some failures. But there were much more failures of 12V battery and starter when they used it for S&S. MH is more complicated, but so far seems more reliable. Same way there are ECU failures or injector failures. Would you really want to go back to using carburators? I wouldn't, even if in theory there are more things that can fail with ECU and fuel injection.
Those "puny dozen horsepower" also has 200Nm of torque, which is more than 50% of C300 ICE engine. And it's available from 0 RPM. It means, that this torque helps to start engine in unnoticable way, get the car moving before ICE will get up to decent torque and help to get the car quickly moving from low revs. Turba lag is not something you can fix with chip tuning. It's the property of turbine, which doesn't work below certain revs and no matter what you do, it will not start working well, as it needs certain pressure of exhaust gases to get it running correctly. This "puny" 200Nm electric motor is providing this toruqe before turbo can get up to it's speed.

Nobody is saying, that you should be enthusiastic. You don't have to (i'm also not "enthusiastic" ). But you don't have to picture it as if it was some fundamentally flawed and useless system (which one could get from your previous post). It's not.
You're right, good that we have a choice. Question is for how long?

 

Not disputing any of this benefit. Only that an ancillary system like MH shouldn't be designed to shut down a vehicle as a consequence of a fault condition.

 

Well, it is what it is. Whether we want it or not, cars got much more complicated during last years, partially due to environmental requirements.
I prefer this kind of complication and car potentially going into limp mode, than being burned alive in a car with electric door handles which didn't work when needed
And again - issues with MHEV are rare. I understand we could complain if it would be failing often, in many cars. But it's not the case.

 

Looks like it was officially confirmed, EQ branding in the model like EQS, EQE and the transition period such as the newly announced Mercedes-Benz GLC 400 with EQ Technology, Mercedes-Benz G 580 with EQ Technology will eventually become Mercedes-Benz GLC 400 electric https://www.autoblog.com/news/merced...l-evs-electric
