Mercedes-Benz USA CEO: We're Undecided on Diesel for U.S.

Diesel isn't worth it for 3% of sales, especially when electric is the future.   Might as well just invest in the future, work on the 48 volt system and new inline engines and hybrids.

With Tesla's system being an 84V to 265V system depending on the charger used to recharge the auto. One has to wonder why only 48 volt system for MB especially when Porsche is going with an 800V system in the Mission E?

Because 48 volt is for gas engines, replacing the 12 volt system that ever other car has.

And they have other plans for Tesla.

So you are saying MB is going to move all ICE to 48 volt systems too?

Yes, inline 4, inline 6, V8 gas, and inline 4 diesel which looks like it won't make it here.  Four engines, all with 48 volt system.  Which will clean up the number of engine offerings and get fuel economy up about 15% across the board.

If MB would really devote themselves to a singular engine vision, they could bring out an I8- it would be as smooth as an EV.

a friend recently bought a titan diesel and took it back the next day.

some of these states like mine mandating certain percent of biodiesel (i.e. government mandated spiked fuel).  Friend's Titan specfically mentioned warranty is void if too great percent of biodiesel.  Some of these other Euro diesels have limits as well.  My guess is with the stupidity of select states creating warranty hazards for potential new buyers, why would you even try to bring any more over on expensive rigs like this.>?

I really have to question the sound decision on this. They might as well just keep improving their ICE line as is and build their EV line on a far superior electrical system.

Having slept on this, from an engineering standpoint I get it that they would have a single electrical harness for the auto. Yet this also means they are going to spend a fortune on R&D to do this, they will also now have issues with mechanics who mix up the existing 12v line with their newer 48v line and I can see all kinds of mistakes being made by the mechanics.

Every car maker will go to 48 volt eventually because they will need the gains to hit CAFE.  They will have to do it to get over that 50 mpg number, gas engines alone will never do it and the EV take rate is too slow to pull the average up fast enough.

Mercedes spends over $1 million per hour on R&D.  It is costing a fortune but if they are ahead of the game in 2020 it will pay off.

So you're saying they will be Hybrids then based on what I am reading. That makes sense, but then we have seen plenty of 12v Hybrids that are over 50 mpg.

Basically all of Mercedes gas cars will be light hybrids with a 15 or 20 hp electric motor and no more alternator or tradional starter motor.  I am not sure how it is all going to work but the 2018 S-class is supposed to be the first car with it.

Not sure that would fit under the hood of an E-class or AMG GT.

They can both be turbo 4s.
