A manual transmission can do the same thing.

It can slow a vehicle without using the brakes, but it's not going to return any of that energy into moving the vehicle forward again.

Hydraulic Launch Assist

Interesting. A KERS system for commercial use?

 

[rusty ol ranger]

This is prolly stupid but...

Why couldnt they make a driveshaft out of a torsion spring type material, so when you stepped on it instead of tire spin the excess accleration would whind the spring up and launch you harder?

If that makes sense.

That's not a manual transmission using engine braking. It's a regen braking system, it's just storing the energy in hydraulic fluid instead of a battery. From the article:

"The Eaton Hydraulic Launch AssistT (HLA®) System utilizes regenerative braking and is being initially targeted at refuse trucks.


Eaton''s Hydraulic Launch Assist System has two parts: regeneration and launch assist.

Regeneration

During braking, the vehicle's kinetic energy drives the pump/motor as a pump, transferring hydraulic fluid from the low-pressure reservoir to a high-pressure accumulator. The fluid compresses nitrogen gas in the accumulator and pressurizes the system. The regenerative braking captures about 70% of the kinetic energy produced during braking."

OK, lets everyone remember why we are on this forum...to have a bit of fun and to ask questions and exchange ideas and to solve problems.
Lets all play nice.
Lets remember that EV's are still aways off as far as becoming main stream. Not only the vehicles themselves, and charging stations, but an entire infrastructure to care, maintain, and repair them.
It's gonna be a number of years before they become as reliable as IC vehicles (think Tesla's that catch fire or explode).
Those of you who are waiting to embrace them, more power to you, and I won't fault you As for those of us who still and will always like IC vehicles (myself included), thats our choice.
Unless gas stops flowing, I will most likly never own an EV. My son/daughter in law, in their 40's now, maybe.
My grandkids, it's probably a 100% deal that they will be driving an EV. It's just the nature of progress
There was a time just 35 years ago when almost no one owned a portable phone, and now look at us...the cell phones we have now have more computing power than all the moon landers combined.
We think nothing of looking up just about anything on our home computers, while 30 years ago we were still waiting for catalogs to come in.
Remember going to your local parts store where they had a rack 8 feet long on their counters with parts catalogs.
When jet passenger aircraft first came into use, everyone was afraid of them as they couldn't "see" the props spinning...what in the hell was holding that plane up ?
ABS, air bags, traction control, computers, radial tires, were all looked upon with suspicion when first introduced. Now their all standard and work.
History will always show that people are very stubborn when it comes to change unless it's forced upon them. It will be the same with EV's, but it will happen. Won't affect me cause I probably won't be around, but you 30 and 40 year olds will be.
I'm fairly new here, but I do hate to see a post started that turns into a pissing match and members belittled for their opinions.
Now, I'm stepping off my soap box, so ya all play nice.

I know, but for awhile there it got kind of heated and I thought someone would get physical.

I'll fight the internet! Bring it on you dirty ones and zeros!

It's fine if they're not for you, but lets not spread false truths about levels of reliability without any data to back that up. They're already more reliable than ICEs though. They require less maintenance than ICE powered vehicles. Chevy has been selling a 230 mile EV for 3 years that can be serviced at any GM dealer. Hyundai and Kia sell cheap electrics with really good range. And we're about 11-12 months from Ford having a similar vehicle in all of it's showrooms. I don't want to confuse the issue too much, but The Honda CRV and Toyota Rav 4, two of the best selling vehicles in the world, are offering Plug in Hybrid versions in 2020 along with the new Lincoln Aviator PHEV and are all considered EVs. They're becoming more and more mainstream very quickly.

NYC has a large fleet of vehicles, several of which are either hybrid or electric. Earlier this year they released their first report on average maintenance costs per vehicle type and on average, EVs were several hundred to over 1000 less per year to maintain. The fully electric version of the Ford Focus averaged almost $1500/yr less in maintenance costs than the gasoline Focus:

New York City says electric cars are now the cheapest option for its fleet

The data is in.

Here's a maintenance log for a limo company that puts about 17k miles PER MONTH on each of their Teslas:

If that’s the final production design, or pretty close, you’re going to see most of them get wrapped. Here’s a 90’s version...

 

[Grumpaw]

What your noting is true, BUT, there are over 250 million vehicles on USA roads right now, and EV's are just a spit in a bucket compared to them .EV's are coming, in dribbles now, but in a flood 15-20 years from now.
So. lets just be happy with what we have for now, the future will be here soon enough. Silly to argue about it now.

When I see a 30 year old EV with 300,000+ miles on it driving around the rust belt then we can discuss reliability...

Not many ICE vehicles of that vintage in circulation.

Rust in the rust belt don't care what makes it move... and stainless isn't really stainless. It is stain resistant.

Agreed. I even gave a similar timeline. I did some admittedly rough math earlier in the thread that we'd be looking at almost 20 years for all of the vehicles on the road in the US to be EVs if they stopped selling ICEs right now.
