A new 3.0l i-6 is coming to the new Mercedes S-Class. No belt/pully

Sounds good.

That's awesome I knew the i6 would stick around

>Sounds like there are a lot of new parts that can and will break
I need this

>>16097117
>add 20hp when you floor it.
wow

Honda's mild hybrid system lives on...Because this is pretty much the CRZ and Insight's method of electrification. Elec motor on the ass end of the engine before the tranny, makes auto stop and start a breeze. Also would allow them to use a manual gearbox, but this is MB so it ain't gon' happen.

>all the pistons always at the same level
Primary balance must be terrible.

This is cool

This is how hybrid power should be used desu
Augment the performance of the engine with electric power instead of tacking on a pifgat electric drive system

>>16097133
>Sounds like there are a lot of new parts that can and will break
Why do you think that?

No pullies and shit to replace and break, just wires. Electrical wires are much less likely to get fucked up.

It also makes the engine shorter, as the 15kW motor is smaller than the accessories on the front end would be. More can be packed in front of the firewall to the sides of the engine.

The 48v systems are also much much lighter than the traditional 12v.

>>16097140
Actually it's surely more than 20hp. Probably more like 35-45 because there is electricity stored in the small amount of batteries/capacitors to power the AC and other accessories instead of them drawing on the engine under full load.

The engine itself is over 400hp, so it's like adding around another 10% compared to a conventional system, on top of improving fuel efficiency.

I'm not sure it actually adds more weight when you take into account the removal of the alternator, the lighter weight of the 48v system, etc. Maybe like 50-75lb at most; will have to weight and see. Well worth the power and efficiency gained.

>>16097210
Agreed.

>>16097210
>>16097200
I hope some company starts making standalone conversion kits of stuff like this. Bad Obsession Motorsport could really use this for their Mini project, and it'd open a world of possibilities for kit car builders.

ah yes, because E V E R Y B O D Y knows that electrical is much easier to repair by yourself, rather than that fucking useless mechanical garbage, amirite?

>>16097308

Thank you t. hillbilly holley carb lover.

But he's not wrong.

>>16097308
Modern electrics are way more reliable

>>16097338
eh, its pretty easy to tell if an accessory isn't getting power. then all you would need to do is trace the circuit back. Yes that will require a little more time than checking if the belt is broken, but modern electronics and motors are pretty rock solid.

I would gladly take the weight reduction, improved economy, and packaging over a slightly simpler belt.

I have daily driven 20 year old cars and never had a significant electrical failure. I have had temp sensors fail, but that is it.

>>16097357

>I have daily driven 20 year old cars and never had a significant electrical failure

But we're not talking about 20 year old cars, we're talking about modern cars with modern electrics that are a fucking nightmare......and in a lot of cases nigh impossible to troubleshoot yourself without manufacturer specific equipment.

...and jesus christ, modern mercs and their electronics are anything but "rock solid".

i want to like it but it just seems like lots more things to go wrong, in areas that have very infrequent service lives and if they go wrong start taking the engine with them

Unless you buy german that is...

>>16097308
Modern electrics are way more reliable than belts, dude.

Not to mention that holy shit vacuum lines are on a whole nother level, which is the main problem with those cars you listed, you fucking moron.

Go bitch about electric transistors replacing vacuum tubes while you're at it.
Hur dur it's so much easier to detect a blown vacuum tube than a defective transistor, yeah that's shit that matters.

>>16097342
VW says no.

>>16097228
Yeah, I'd really fucking love to see an aftermarket hybrid turbo kit.

An ecu compatible with many engines and the turbo controls, plus the turbo itself, and the capacitor.

The other bits might be too much for aftermarket. You'd need modified front engine housings to mount the electric motor.

>>16097117
but will it have a dipstick...

>>16097117
How long until they electrify the valve timing and get rid of conventional belts/chains?

>>16097689

>>16097228
It's not likely, vairable geometry turbos have been around for a while, but it's still not used for many tuners. But I really hope I am wrong.

Eggsplain moar about the eletric turbocharger?

Would be possible to put in a 4.3 I6 Chevy?

>>16097117
I do hope this becomes the norm.

Most of /o/ doesn't realize it only takes about 75hp for the average sized car to cruise at 100mph. A small electric motor, just 20hp like this, does a lot to increase efficiency on top of having the electricity to spool the turbo immediately at any RPM range.

It's useful for any car, both commuter and the most pure of sports cars.

Give me something with ~.65-.9 L/Cyl and undersquare.

>>16097812
Yeah they're using the same exact pistons they use in their i-4 and v-8s, I believe.

Hybrid electric turbochargers have been used in them for a few years now and is finally trickling down to consumer cars.

My econobox only has 50kw and still gets up to 110 mph.
Nobody seems to realise that the efficiency of a engine gets lower the lower the load is, as long as it doesn´t exceed about 70-80%.

>>16097812
You wouldn´t be able to rev that high with a longer stroke.

You won´t get much power out of a Engine like that.

>>16098264
Who needs power when you can ease off the clutch and get rolling, all without pressing the gas?

What could possibly go wrong

>>16098129
Actually isn't there usually a sweet spot, usually around 30% or 40% energy load, and lower load is less efficient? I guess it could be higher still.

Pretty much all the hypermillers recommend to accelerate a bit "briskly" up to speed to load the engine a bit more, and that's more efficient than just slowly easing up there.

>>16098272
Everyone that wants to go fast.
If your first gear is that short you will have to shift extremly early.
Also with a shorter first gear every car could do that.

>>16098285
I should have mentioned that in my autistic fantasies, this hypothetical engine is an iron block/head, OHV, 10 valve intended for use as a base engine for half ton trucks.

>>16098283
The sweetspot is at 80-90% throttle opening and around 3000-4000rpm for most european engines, wich gives you about 70% of their power.
The sweet spot starts at avout 50% throttle an is usually betweein 2500 and 5000 rpm.
It is more efficient to use a bit less rpm/power since you will usually drop out the sweetspot when you reach you desired speed.

>>16098296
>iron block/head
>OHV
Sounds pretty damn old.
>10 Valves
For how many cylinders?
1?
2?
5?

You think we can get Chrysler to bring back the AMC block for this shit? I'd love to see a new Jeep with the proper engine for once. Though they only seemed to fuck it up as time when on (0331 head).

>>16098320
5, as mentioned in my post describing the engine here >>16098229

And yeah, I want an old school motor that would be easy to work on and maintain.

>>16098272
>>16098285
The current gen stang has a pretty short first gear. No problem getting in 1st gear from a slight uphill even without gas, but its at 15-20mph ~ 4k rpm

>>16097689
Did someone say Koenigsegg FreeValve?

>>16098358
Why should it be OHV and 5 cylinders if it should be easy to maintain?

>>16097812
They are doing this because of global regulation

http://www.motortrend.com/news/500-club-mercedes-benz-expands-its-new-500cccylinder-engine-family/

>>16098374
My first gear gets me up to ~70 km/h or ~44mph, so it is much longer, with this gear ratio I have to be more carefully with the clutch.
If you would try getting of at a similar gear ratio with your stang you would have to use the clutch as much as I do.

maybe 10% of the time the cause of the problems these cars have is a damaged wire or bad ground, it's almost always an intermittent problem in the module


The system makes a lot of sense for Mercedes but it's going to be even worse out of warranty.
