EQ Boost mild hybrid walkthrough | Your Mercedes-Benz Explained

EQ is electric intelligence from Mercedes-Benz. One of the EQ technologies used in our road cars is the mild hybrid system called EQ Boost. In this video we dive in to this system and find out what it is, how it works and how it can improve your drive.

EQ Boost uses an Integrated Starter/Generator (ISG) and the 6-cylinder engines utilise an electric compressor. The system output is 14 hp or 22 hp depending on the model and an additional 250 nm of torque.

Think of it like this: boost power, boost torque and boost efficiency with EQ Boost.

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 😊

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

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

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.

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!

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 ?

[Bayanda]

Thank you for the explanation, I drove my sister's C180 and I thought it was hybrid 🙈 she couldn't explain to me what the "charge" gauge was for in her car

[lepaul]

Is it good for the engine and filters to get switched on and off so many times and for short periods ?

[nizzan]

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?

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

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

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

[slav]

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

[carloandfamily]

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

[swissnaturek]

When should we expect to see it on E400d?

[kevinspaceprogressrocketry]

Question can the boost move the car?using e

[kachi]

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?

[Adamasher]

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