Buried in a recent Autocar article on the various approaches Mercedes-Benz will take to meet both short- and long-term CO2 requirements in Europe were a few statements related to electric vehicles.

This one, from Thomas Weber, the man in charge of research and development for Mercedes’ passenger vehicle division, caught our attention:

“By 2020, we expect the energy density of battery technology to have doubled and the cost halved.  Without any other changes being made, the range of the B-Class Electric Drive could increase to 185 or 250 miles.”

So, without any changes other than increased energy density, the B-Class ED could boast Tesla Model S-like range.

Weber continued:

“Lithium sulphur will be the next step after lithium ion, followed perhaps by lithium air. Lithium sulphur is comparable to lithium ion but lithium air will be a completely different world.”

Guess it’s about time to get ready for a complete different world of EVs.

Separately, Harald Kroger, vice president of e-drive for Mercedes-Benz, commented on the limited of range of most of today’s electric vehicle:

“These questions often evaporate if you use an EV on a daily basis. A lot of customers realize their regular driving is covered by a 95-mile range.”

To us, it seems that Mercedes-Benz is leaning more and more towards an electrified future, which for now the automaker claims will involve fuel-cell vehicles too, but perhaps that will change as Mercedes sees that fuel cells are unnecessary as range continues to grow.

If true, sounds like a good reason to sell their Tesla stock. If there’s anything to this stuff — who knows, but probably just a matter of time — it may mean that Tesla’s range advantage would be yesterday’s news.

Wouldn’t Tesla then have a range of 500 miles, retaining it’s range advantage?


100 EV miles for plug-in hybrids

200+ miles for sub $30k EVs

500 miles for $70k EVs

I would be happy with 180-200 miles. 🙂

At some point, more range isn’t worth the tradeoffs of less storage, more expense, worse handling. That probably starts to happen around 200 miles of range. At 300, few would be willing to sacrifice anything for more.

The big boys such as VW who are the among the leaders in lithium sulphur are putting billions into battery research.

Will Tesla be able to get its hands on it, and at what cost?

So far VW’s billions in research adds up to e-Golf and e-Up!.

Will VW be able to keep up with billions spent by battery veterans like Panasonic,Samsung SDI and LG Chem plus the thousands of battery startups around the world?

They don’t need to.
They are perfectly clear that they will not manufacture cells, and so they work in conjunction with Panasonic, and Audi are now also working with LG Chem.

Their ramp up of battery research has been relatively recent, I believe, as previously they were happy to simply use the cells available, but since they are now in production of both BEV and PHEV cars and feel that they are onto something with their lithium sulphur technologies they are pouring in the resources now.

The VW group tends to work in projects, and the last phase of their projects aimed at two things, obtaining a leading position in China as the world’s biggest market and building new platforms for all their models capable of several different power systems, including electric.

Their present phase aims to dominate in electric drive, so they are electrifying all their models, and to greatly increase their production and sales in North America.

Battery research is tied in with the first of those goals, and so a substantial part of their $13 billion or so R & D budget is going into it, as a lot of their $22 billion investment budget is going into ramping electric vehicles.

Tesla’s R & D spending was $325 million up to the end of September, so around $440m pa, which was spent mainly on their new motors and the Model X, so they are somewhat out-gunned in battery research cash.

One of Tesla’s main advantages right now is DCQC for free. The B-class doesn’t have that option. Range doesn’t matter as much when you can DCQC for free for long trips.

Tesla would love it if Mercedes wanted to share them, or the cost of building their own CCS network would not be very high, especially if shared with the other manufacturers using the standard.

It would be even better if all the automakers chipped in to start building tri-DCFC stations… instead of 87, 89, and 91 at the pump you get to choose Chademo, CCS, or SC connector.

I see, so instead of the “gas station” it would be a “power station” with a similar layout. Pull up to the “pump”(hub?) slide the credit card, pick your handle and charge. If you have enough of them, wait times would be minimized.

At a crowded gas station, I would have to wait 10-15 minutes anyway for a pump to open.

Ron Baron (of the Baron funds): “All of us will likely be Tesla customers in 25 years”

By “all of us” he might have been talking about the set of people who invest in mutual funds, but the point stands…

Considering Tesla is the one who built the B-class EV powertrain, I don’t think they’re the stock I’d be selling. On the contrary, I’d be selling every other auto maker (except BMW, as noted below).

“Tesla’s car culture is far different from that of other car companies,” Baron wrote. At least, all car companies except for BMW. Baron noted that two of his analysts recently visited BMW in Germany and the BMW financial team believes that a “revolution in the drive train is underway. … We believe that BMW will likely phase out internal combustion engines over the next 10 years,”

Yeah but, who are they going to buy the batteries from? Probably Tesla.

BS! They can do an EV with 150 miles right now!

+1. The B already gets 110-120. Production cost is the only honest excuse.

Well of course they can. Any of the automakers can produce a 200+ mi EV if they wanted. The question is whether or not people will pay for it. Tesla shows that there is a market for it. It just happens to be the same market that would buy an A7, 7-series, S500, etc. However, Nissan/Renault, Chevy, and Ford show there’s an even bigger market for more affordable EVs based on the dominant Leaf and Volt sales (and increasing FFE/C-Max Energi sales.)

Not surprised they’re looking at Li-S next. Though I’ve negatively revised my own internal time table for Li-S in EVs (from 2017 to 2018-2019) based on beefing up volumetric density to match Li-Ion but far ahead on the grav. density (Li-S 2018: 500 Wh/kg, 750 Wh/l). By then, you could have a pack in a skateboard form factor (Tesla) that goes 250 miles, but weighs between 1/3 and 1/2 of the current pack weight (battery cell weight reduction, reduction in protection circuitry for safer Li-S cells), cutting about 600-800 lbs off the current vehicle weight (15% total vehicle weight).

Even on a same range basis Tesla has now clearly shown it can make more appealing cars that look better, perform better and have the magic Elon touch that makes them unique and desirable.
That is very different then a Mercedes bulbous pumpkin look alike class b, BMW makes it somewhat better but it is time they turn out a true sedan out of their i3 prototype.

The B Class ED has a battery almost double the size of the battery in the i3. If the B-Class got the 124 MPGe that the i3 does, it would have a range greater than 150 miles.

If BMW wanted to put a larger battery in the i3, they could accomplish the same thing.

Nissan’s advertised battery replacement cost pegs the consumer cost at about $250kWh. Tesla is in the same neighborhood.

The price premium for that 150 mile range i3 would likely be in the neighborhood of $5k.

This just seems to be an article further indicating that ev’s are the wave of the future.

I will believe a 250 mile mass produced EV when I’m able to see it drive down the road or if I’m able to go sit in it at the dealership. Other then that all this is stories and science fiction.
