The dimples act exactly like the surface of a golf ball for aerodynamics it actually smooths out the boundary layer air flow for sound reduction.

3:15 - Those dimples serve the same purpose under the car that they serve on the golf ball. They create a boundary layer of air around the surface, allowing for smoother airflow around that boundary layer. On the golf ball, that gives the ball greater aerodynamic efficiency to allow the ball to travel farther. On the underside of the car, it will allow the car to experience less drag due to the way that air is made to flow underneath it. The Ferrari F12 has air channels that run from the grille to the center of the hood, and from the upper-outer sections of the hood to the sides of the car just below the A pillars. Those channels help to create a similar aerodynamic boundary effect on the top & sides of the car.

I work on these for a living 🥰 the EQS is even more impressive.

There's a lot of tech in this car but the head-up display is something else. A great review Sarah!

I've been working at an independent MBZ shop for 25 years. This is the kind of POS that will finally make me move on to something else in life. Recently bought a 2020 TRD Pro 4Runner because it's such a "dinosaur". I want a car to work for me...not the other way around. The mere thought of the conversations I will be forced to have with customers about these cars makes me want to retire right NOW! Thanks for the review Sarah!

Love the sparky things when you tap the chassis. I know I can't afford a MB, but seriously appreciate the crazy engineering. Absolutely love your way of describing a beautiful machine such as this. Ruffles at the bottom of your pants are neat and unusual.

A metric Sarah , you have earned , even more respect

Mercedes tech here. Had the opportunity to drive one of these a while ago (still havent broken down so we havent seen these in the shop yet). But all I can say is that this thing is on a level of its own. I have never in my life driven anything like it, its an experience you have to experience to understand. One thing Sarah forgot to mention that is really cool on these is that the whole instrumentcluster is 3D, which is especially cool if you have the nagivationscreen selected, feels like looking into the screen.

OMG... Outstandingly subtle eyebrow raises... Visual ASMR! Top quality content Sarah! Nicely done as always!

That's a pretty cool car. I'd never watch car reviews if you didn't do them and yours are probably the only ones I'll ever watch. So thank you for bringing some cool stuff into my life :)

You're completely on the money giving it the lowest wrench score ever. I've logged a lot of miles in high- mileage examples of MB S550s as a professional driver. The massage feature kept me from having to visit a chiropractor in 80 hour weeks behind the wheel. There is a reason why these tend to be leased, and why they lose >$100K in value by the end of a lease. They are extremely fun to drive right up until they're not. Too often they've become so mechanically crippled that to fix the components only MB has the diagnostic workstation to reflash or reset, you would be way ahead by parting it out. So they stay broken. I'd wager 95% of the black car service MB sedans are limping along with some major feature or several being broken.

Aluminium? Proper EU/Canada speak..... I love your charisma. A breath of fresh air. Your channel is absolutely worth a subscription.

I’m glad the all-knowing algorithm decided finally to have you show up in my feed. You’re amazing!

Honestly this channel is amazing! It’s nice to see someone talking of the mechanicals and not just talking about interiors and entertainment systems. Thanks for creating this 👍

Golf ball pattern is for aerodynamics... Myth busters did an episode about it with successful results.

As a car enthusiast listening to your reviews gives me the biggest joygasm in the world! Happy New Year and keep up the great work! 💖👍💰

Mercedes Benz always pushing the boundaries to the highest standard on car industry.

Who knew cars came with magic seats that can make women feel that way. ;) Great review. Amazing tech and fast for such a big, heavy beast.

Happy New Year thanks for another review! Looking forward to a great year!

The golf ball dimples are for aerodynamics. There's a video of The Myth Busters that tested that theory on a cars outer body panels and it was shockingly impressive. Definitely worth watching.

Yes, I like the discussion on the head up display also. Thank you Sarah for this review.

Mercedes engineering has been superlative for decades. But, as Sarah noted at a couple places in her review, service can be insanely expensive because some of the components are very difficult to access, and some require partial disassembly of other components before you can even get to them, not to mention the specialized tools needed for actual service. Finally, note that Mercedes is NEVER on anyone's list of "most reliable" vehicles. With a lot of TLC ($$), they can last a very long time, but the cost per mile can get ridiculous. No thank you, especially at this price point.

4.5 degrees for handling, 10 degrees for getting into the parking spot in the mall at Nordstrom.

Wow, what a next level driving experience you conveyed from the front seat! All the info and comfort tech there will not be commonplace for years. However, I saw the most joy on your face when you found the pillow in the back seat. Loved that!

Great car and great review to start the new year. The HUD is cool and utilitarian. Worth having.

You look great in that Mercedes! Happy New Year Sarah!

Happy Sunday Sarah!!! That thing is crazy, to be expected I guess. Love the rave lighting for night driving, of course all those torques is also pretty awesome, working on it though, eeesh, lots of expletive laden phrases for sure. Stay excellent!!!😎

Yeah, more Sarah!!! Love her outlook on car reviews!!

Amazing car. Great review and content Sarah.

What a great review! Thank you and Happy New Year!

Sara , I have been around cars all my life . I have seen many beautiful cars all shapes all sizes , but you my dear are a knock out !

This is the first mechanical review ive seen and I love it! Im a diehard mercedes fan, but I never get to see a review of one of these newer cars from a mechanic's point of view. It was insightful, thanks!

This was cool. Thanks for the tech breakdown Sarah!

Happy New Year Sarah and thank you for the video.

Come on, pop off .. then into the valley of the beasts . Happy new year Sarah . Girl, you are awesome, an inspiration 💖.

Great review Sarah love all your reviews you do great work!!!

A peach of a review on that Ga Mercedes, love your videos Sarah!

Great review Sara. Thank you 😊 for talking about the Audio Systems between the Lexus and the Mercedes. It’s hard to find people that talk about the differences when it comes to audio. In most cases poor audio is a dealbreaker unless were speaking about an exotic car where performance is the up most concern

Happy New Year, Sarah.

I learn so much from your reviews. They are awesome.

Great vlog Sarah and looking forward to the next vlog

Great video,as always you killed it on the review.keep it up.👍👍👍😎😎😎

Happy new year Sarah, this AMG is a power beast!!!

Next level engistyling!

Sarah I've Been A Huge Fan For A Long Time!!! THIS WAS AN AWESOME REVIEW, Love The Next Level Technology... 💯💯💯💯💯

The panel dimpling: on a golf ball, it reduces overall air resistance. So I expect this application has the same purpose. The skinny antisway bar maintains more compliance on rough roads, but seems inadequate, yes. The difference in lateral resistance to body lean is taken care of by the "E-Active Body Control" system on a constantly adjusted thousanth-of-a-second analysis basis, per the MB site.

Time travelling from 1985 with the legwarmers 😄

Another great review Sarah, thanks so much!

Another great review, especially the seats lol. Really enjoyed watching this one.

Thank you Sarah!

Very Nice Review Sarah!

Cool video thanks. The AMG MUST REALLY BE CRAZY.

Congratulations - I heard every word : ) Have an amazing new year beautiful Sarah!

Awesome technical review !!👍🔥 Thanks for taking off that cover 😁

Thank you Sarah for an excellent start to your car reviews for 2022! Any chance of getting your hands on the EQS next?

Great work Sarah, another enjoyable Sunday evening watching your awsome content 😀 👌 😊 👍

your reviews are so….nicely - different from all the other car reviews. Love it! Keep going….

LOL! I guess you like those magical seats? Thanks for the review and have a Happy New Year Sarah!

Awesome stuff Sarah, love the content ❤

Great job Miss Sparkle fingers. Love your videos.

Thank you for another great review.

It's amazing how far car technology has come. With the Augmented Reality navigation, if the car has active assist technologies like lane assist, collision prevention controls, etc, it could teach you how to drive without an instructor in the car. Amazing car.

Thanks for actual info during a review esp the materials, wow, just wow. I miss the 108 series which was such a dream to work on.

This is the type of car you sell immediately after it goes out of warranty. Love the boots Sarah. Happy New Year!

5:00 Great example of seatbelt tensioning! Watch her microphone attached to the seatbelt jump!

love your work and grind ethics

Another great review, Sarah. I'm glad that you brought up the complexity and cost of servicing a vehicle like this. Lots of people don't figure that into their buying decision and end up having a heart attack when they take it in for service.

Happy New Year Sarah! Another great car review! That's quite the car for 138k! Take care! Can't wait to see more on your grandmother's 94 Ford Ranger!

So much detail. Impressive review..one of your best. Thank you. I love this car. I would like to lease a S series one day.

Very interesting, informative, intelligent and sassy review. Rarely see reviews where the underside and the engineering is so closely scrutinised. Many valid and astute observations Sarah. Whoa all that plastic is scary and looks very cheap and flimsy like it won't last very long. Yeah Sarah sure will be challenging when diagnosing electrical gremlins in 20 years time! Had a friend with a 6 month old E320cdi and Mercedes could not pinpoint the fault so they ended up just replacing all the ECUs and a range of other components, crossing their fingers that they'd managed to rectify it.

The special effects rock!

Interesting Car, I prefer the simplicity of the 1966 230 sedan we used to have.Thanks and Happy New Year Sarah 😀👍🇨🇦

As a new sub I appreciately your down to earth review. Great job.

Golf ball surface is for aerodynamics I believe. Golf Type R has a similar shape on its front spoiler

Gorgeous,definitely 5 Penguin. Car's nice too.Cheers luv ya work, as always

Love the review Sarah. Kudos for the correct pronunciation of aluminium.

@sarah-n- tuned seeing you in expensive cars is oddly satisfying

Another Great Car Review

One of the points that car reviewers fail to highlight when testing cars is RELIABILITY. This is clearly a time-dependent aspect, therefore difficult to estimate when testing a new car for a few hours or a few days. But it is also one of the most important points for those looking at reviews. This is precisely why many of us enjoy your videos and especially the sessions where you lift the cars and analyse them from below. When you show the bottom of the car, many are interested in the technology, but many also try to understand whether the quality of the materials and technical choices will allow the car to last for many years. A tip: you could introduce a score (Ants? Camels?) to estimate the reliability of the car. We all know Lexus are the most reliable cars, but these are beliefs developed over the years and they are not immutable. For example, many reviewers like the Lexus NX 2022 but argue that the Genesis GV70 is better. It would be interesting to see if Genesis is improving reliability and the GV70 can be expected to last as long as a Lexus NX or if it's just a nice car to keep for the first 70,000km.

Great overall score!

MB, knows how to make great cars ........... this is a fine example of class & power !!

I’m digging the editing style

Happy new year.

That is one super-sweet ride!

Nice review as always Sarah. You may want to consider adding a link to your second channel in the description to make it easier for us to check it out. May you and yours be well, j

As said, the golf ball dimples increase aero dynamics, it can also be done to inlet manifolds to increase air flow and can now be found on fan blades, again to increase air flow and reduce noise.

I have the S500 with the upgrade in the rear seats. It's not just heated seats. They have all the functions of the front seats, including massage and 4D sound. A must have...

that seatbelt tightened up when you did the brake test that was pretty amazing

That’s some vehicle. I love the HUD which I think should be optional on many vehicles for safety. Despite your “promise” to take it easy this season, everything you’ve posted has been first-rate. Thank you and Happy New Year! 👍👍👍 ~ John

The version with the 10⁰ rear steer makes these so easy to put on my hoist at work. Love these cars... depending on the version, there are over 110 individual modules. The ball joint nuts are technically single use and must be replaced every time they come off. The front anti roll bar end links bolt right through the upper knuckle... these will be an issue in the rust belt... tons of cool tech in this car too

Great Review

The golf-like holes have an air stabilizing properties and help reduce wind resistance.

Great beat when putting the engine cover on and closing the hood!!!

......Happy New Year! and this was a GREAT review/test. Now, all we need is a Big Trade to get the coin to buy one or two of these! What took them so long to get you to do a Review???? Anyway, do more Night Drives....very cool!!!

5:00 That mic(?) mounted on the seatbelt is a great indicator to show the seatbelt being pulled tight during emergency braking =)

Fantastic channel

Hair New Year, best wishes, health and peace! The dimples in golfballs are supposedly for aerodynamic purposes: the air would cling less to the ball. The nuts or bolts in the ball joints look like Torx to me. Glad to hear the seats were... Pleasing. There's probably a separate cooling circuit for the e-motor.

Having owned numerous Bimmers, I have never lusted for a Mercedes luxury model...until now

Amazing amount of tech in this car, most of which seems to be designed to isolate the occupants from any driving sensations. Obviously, this isn't intended to be M-B's driver's car, nor is this the kind of car people would keep for many years and hundreds of thousands of miles. M-Bs in general are known to become money pits as they age, due in part to the expensive parts and all that complex engineering which requires mechanics to disassemble half the car to get at things that only require removing a few bolts on "lesser" cars. Great review, and it's nice to see a car like this reviewed from a more "regular person" reviewer than typical for something like this.
