EQ Boost mild hybrid walkthrough | Your Mercedes-Benz Explained

[@Platuss213]

Really needed a video to help me understand as I thought the car was a hybrid. I was especially pleased when I noticed this video was made by my local dealer in Bishop’s Stortford 😊

[@stevysan420]

That startup really suprised me 😀

[@DanielSadjadian]

And now of course the AMG models also have E-Performance hybrid systems. Incredible performance numbers 🔥

[@RolandLyngvig]

Well explained. I love EQ Boost in my C300 from 2019 (facelifted)... :-)

[@MrTench8]

It has been standard fit on many Honda's for 20 years, the EQ boost system is almost identical to Honda's IMA system (integrated motor assist) which has been available since the year 2000! My CRZ is a 2010 and has Honda's 6th generation IMA system. Mercedes are late to the party but i am sure will have an equally polished product. Might have to swap our W204 for one!

[@LandLAutomotive]

I'd not looked into IMA in much detail before but every day is a school day! The two systems are very similar - it looks like the main difference is the voltage with some IMA systems running at well over 100v. The CRZ still looks futuristic whenever I see one.

[@chinkang3566]

I happened to own a 2013 Honda CRZ and a 2020 Mercedes C200 1.5 EQBoost Turbo.

[@bangarslough]

Mercedes over Honda any day even if it was running on water I will not buy it

[@archimedesbird3439]

To what extent does it enhance engine braking? Do the brake lights come on if it's substantial?

[@RJ-pz8bk]

not all are integrated. my c class is belt driven starter generator

[@Khans1199]

Nice sporty car 🏎️🔥🔥

[@koeniglicher]

Only M256 with 320 kW get the additional 48V electric supercharger shown at 1:05. The M256 with 270 kW does NOT have this additional 48V electric supercharger. So, it is not all 6-cylinder engines, but just a subset of them.

[@maxagent86]

Thank you for this important clarification. Do the 270 kW engines have an electric motor powering the turbo air compressor at low rpm's to minimize lag?

[@koeniglicher]

@@maxagent86 No, M 256 E30 DEH LA G R (270 kW) does *not* have the electric turbo air compressor. It only has a conventional turbocharger, entirely driven by exhaust gases. To reduce turbo lag however, the crankshaft of the engine is supported by a an integrated starter generator (ISG). This is a flat electric motor ("EQ Boost" marketing term) with 16 kW of peak power, 250 Nm of peak torque that sits on the crankshaft, acts as a starter, acts as a small generator during deceleration and can add some torque at the low end during acceleration. It is supplied with energy from a 48V battery and stores its generated energy in there as well.

[@joanharmonize]

Totally random but i love your shoes

[@nizzan91]

Can you alter in the settings how the EQ boost/regen work? Eg: can you set the intensity of the recharge? how early it starts the regen under deceleration?

[@richardjones7386]

How many cabriolet EV’s are available? One. Smart car. So just bought E 350 Cab with this tech. It’s worth it for the smooth start up alone. Excellent. Great explanation. Thanks

[@LandLAutomotive]

Thank you! The new 2.0 litre 350 engine is brilliantly suited to the E-Class Cabriolet too. We do hope you enjoy your new E 350!

[@FratDag]

Hi , i do have c200 4 matic cupe 2020 with eq boost , I would like to know does it makes sound when we break the pedal, because mine does a sound when I touch the break padle , it is really smooth sound but it may be annoying sometimes. Does it normal ?

[@carloandfamily5051]

You forgot to mention the AMG 4 door GT 43 and 53. They both have the EQ Boost system.

[@LandLAutomotive]

We never got those models in the UK officially, though I believe there are no more than 6 AMG GT 53s on our roads.

[@slav999]

Do all C200 4matics from 2020 onwards have EQ boost or is it a specific model? I cannot find information whether the 184hp c200 4matic petrol engine has it by default

[@416to212]

Great content!

[@LandLAutomotive]

Thank you!

[@teemo988]

Reliability problem with such complicated design?

[@mbm-j3z]

Hello I have a Mercedes Benz C200. But I can’t find the The EQ Indication located on the gauge. Is something wrong with my car

[@wineyestap1172]

mercedes 48 volt battery problem engine stop

[@kevinspaceprogressrocketry5590]

Question can the boost move the car?using e

[@LandLAutomotive]

Great question! Only under certain conditions - the system is there to run with the engine rather than instead of the engine. However, when slowing to a stop the engine can switch off and the electric motor will move the car for the final few metres before stopping. This is to extend the start/stop time in traffic and help to save fuel even in heavy traffic.

[@swissnature4k]

When should we expect to see it on E400d?

[@LandLAutomotive]

EQ Boost is starting to make its way to the diesel engines. At the moment it is available with the 2.0 litre 4-cylinder only but I hope it arrives on the 6-cylinder engines soon. The in-line 6 diesel is one of my favourite engines at the moment.

[@bernardjukic9545]

E400d 4matic 2020 has it..only problem is with constant start-stop in town it feels sluggish and has delayed start... annoys more than regular cars...

[@kachi1122002]

GLE 400d diesel vs 450 petrol which one is better in terms of ride quality, driving experience? Does the EQ boost technology impact on 450 performance? I heard the 450 engine lags and the battery makes whining noise, is this true?

[@LandLAutomotive]

On paper the two are very close with the same 0-60 time and nearly identical power and combined torque outputs. In terms of ride quality they both have the magic carpet effect on the road surface - all 6-cylinder GLEs in the UK get AIRMATIC air suspension as standard. The instant electric assistance to the drivetrain makes the 450 engine lightning quick to respond. In my experience the addition of EQ Boost improves the driving experience as the engine itself doesn't need to be worked as hard to get going. On the road you will naturally find yourself driving a little bit more economically to maximise what the EQ Boost system can do - like using gliding mode as and where you can. The battery itself is silent, I've never heard any whining from the engine or transmission whilst driving EQ Boost models.

[@user-qc5lc9gv2d]

Will 48v system stay charged over 5 months unused with only a 12v trickle charger?

[@wolfsbite]

where can you see how much it is charged

[@LandLAutomotive]

For EQ Boost mild hybrids there is no display for how full or depleted the battery is - the 48v battery is around 0.5 kWh in capacity but it will display whether the system is harvesting or using power underneath the rev counter on the instrument cluster.

[@Adamasher8888]

Hi can you please tell me, What is the real world mpg on the Mercedes s500 eq boost? ...

[@LandLAutomotive]

For the new model, combined fuel consumption is between 32.5 and 34.5 mpg WLTP. OF course this can vary depending on your route and how you drive but on long motorway cruises the in-line 6 is fantastically smooth, quiet and can easily achieve the up to 38.2 mpg figure quoted for high speed sections.

[@Frankie5Angels150]

Does the 2023 C-43 AMG have EQ boost?

[@LandLAutomotive]

It does - in a slightly different way! As well as having the mild hybrid electric motor, it has an electric exhaust gas turbocharger too. This sees an electric motor mounted on the shaft of the turbine itself to allow it to spin up quicker than you can say EQ boost. This does away with the need for the electric compressor as seen on the six-cylinder engines.

[@josesedes5133]

I own a brand new FL Amg a 35 and wonder if the EQ boost if the same as in the C-43 AMG. Thanks in advance for your feedback@@LandLAutomotive

[@gogutzy]

EQboost, big words (lots of marketing budget) for a technical solution that's found on the cheapest Japanese cars: Suzuki's.

[@Frankie5Angels150]

But then you are not driving a Mercedes. It’s still an effing rice burner.

[@spewgilist]

You notice it more on deceleration

[@LandLAutomotive]

Definitely, to my senses it will use the proximity/active emergency braking sensors to help decide when to start recovering energy or restart the engine.

[@spicymeatball07]

Next video pls lay off the blue smarties , slow the video down and pls make sure some of the video is in focus .

[@conradmilson6654]

Suggest you google MB who are being sued in the USA for a dangerous failure of the 48 volt battery causing the cars to cut out in the middle of highways or just about anywhere. And they are not covered by the warranty after three years. Good sales pitch but not a good buy.

[@stuartmitchell8736]

Fantastic BUT it’s got an exhaust.I love Mercedes had them since 85,I can’t understand why they are still messing around with ice.I now have an I-PACE, out off all the cars I have had this is the best by far I have had Es,SLs,Cs and Ss.Why waste R&D on this primitive propulsion?

[@LandLAutomotive]

Great question - it's all in the interest of increasing efficiency whilst reducing emissions. As a bit of a dinosaur I do like a good engine so the addition of something that boosts performance and fuel economy is a winner for me personally. Similar mild hybrid systems are starting to appear across the market with Audi being one of the first to introduce 48v systems with the SQ7 TDi. Our friends from BMW and JLR are also introducing mild hybrids across their combustion engine range.

[@dsingh2888]

I bought 1.5 MHEV C200 AND it's completely garbage on Fuel economy 😅

[@RJ-pz8bk]

it is you are right and there is turbo lag

[@RC-xr2hm]

EQ booster also caused lots of problems. You can google to find out the problems across different models. Mercedes still does not have a solution to fix the problems.

[@drsuarezneuro]

Really?

[@AC-ec2yr]

Do uou need to charge it unbelievable .rubbish review

[@odgie5228]

Use your brain for goodness sake, it's mild hybrid, not plug-in hybrid...48v battery is peanuts and gets charged via driving. If you can't understand the difference between mild hybrid, plug-in hybrid and full electric, choose a different car.

[@bastogne315]

Hybrid is bollox!

[@nizzan91]

this kind of hybrid makes a lot of sense actually, not a lot of disadvantages while helping out the engine when it's least efficient

[@jontyrocks3]

Or just go full electric and get much better acceleration with exceptionally low running costs 😏
