RAM 1500 EcoDiesel or RAM 1500 with an eTorque module.

 

But electric vehicles have good low end torque, it only goes down as RPM goes up. Not good for towing.

Id think they would produce enough to be decent? Well I did forget about how it drops with speed


I spent $2500 on building my PC and all i do with it is play MTGA & watch anime at 720p...

"Here is some advice that might have gotten lost somewhere along the way in your life. 

 

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

 

Follow these simple rules in life, and I promise you, things magically get easier. " - MageTank 31-10-2016

You can definitely tow with EVs.  Even a Model 3 can haul a decent amount behind it... though I'd probably use a Model S or X if I were hauling a large trailer.

Not without cutting the battery life in half. Whereas a Cummins or Powerstroke may lose 20% on heavier trailers, and up to 40% of you're really pushing the truck to its limits.

 

Then there's the question of is it fun to drive. Electric cars have nearly the same characteristics as some older CVTs, just that electrics can handle torque better. Many modern CVTs simulate gear shifts, and Toyota has one with a launch gear, because many people that bought CVTs didn't enjoy the car for its acceleration characteristics.


Yup the yup.

He's pretty much accepted it at this point. I think this is a positive step, as Musk doesn't seem stable enough to be a leader by himself. I don't expect this to stop him from doing silly things, but at least at a business level the impact will be more limited going forwards.

 

While not an expert, there are rules on disclosure of information that would be of interest to investors, to help create an even playing field. Twitter is a public forum so that in itself isn't likely to be a problem. The problem, which they got him on, was that the "secured funding" didn't happen and most likely never existed in any tangible form.

I haven't been in EVs often, but I have been in them... and I'd say they're great experiences.  That massive, continuous wave of instant torque is something to experience.  And since they have low centers of gravity, they're pretty well-planted in turns.  People have complained about CVTs in the past (not so much with newer iterations) in part because they're usually mated to modest engines that just aren't exciting.

Banks have received huge fines, 100's of billions of dollars between them . The difference is bank CEOs tend to keep a low profile.

YIKES.

 

Very few perpetrators of individuals taking bailout finances were prosecuted. The banks themselves were sometimes fined, never the ceo's.

People complained because they were too linear and had no gear shifts, which to them is boring. I agree with that sentiment.

 

People stopped complaning about CVTs because modern ones now mimic the feel of an automatic tranny, defeating the purpose. Most of them still can't handle that much torque.

Too linear, it's predictable and boring. The responce, power, and acceleration of ICEs, particularly turbo and supercharged engines, is far more fun.

I'd say that a sufficiently powerful EV is still going to be fun to drive; you just don't have that familiarity of gear shifts.

 

As it stands, this feels like a bit of a moot point... the industry is moving towards EVs, so there's a good chance you won't be driving a V8 twenty years from now.

Not really. Beyond adding a few models, the industry is happy to keep going with gasoline Ottos and Diesel engines.

There really isn't. EVs can't effectively replace large engines and the enthusiast market is too large to abandon it.

You haven't really been paying attention, I think.

 

GM will have 20 electric car models on the road by 2023; Ford will have 13 global EV models by 2022; VW will have several major models; Toyota and Porsche are dropping diesel sales.  And that's not even ten years out.  This doesn't mean everyone will be driving EVs in 10 years (or even 20), but we are approaching a  tipping point where EVs are a regular part of the automotive landscape.

 

Also, who said EVs can't effectively replace large engines?  There are already electric semis and buses (either here or on the way) that can handle mainstream duties.  Tesla has an electric pickup on the way.  You'll soon see electric supercars that decimate gas rivals in every category, not just short-term acceleration.  And saying they "can't" replace large engines just seems very... short-sighted.  As if the technology we have now will never advance, and that we should just give up.

Aren't most plug-in hybrids serial by definition?  That is, they typically run on electric power first and switch to gas only when they run out of battery.  Some performance models invoke the gas motor to maximize performance, but otherwise...

Serial means electric drive only, parallel means there is direct drive capability from both the electric motor and the petrol/diesel motor. The downside to serial is they require a larger battery so full electric is often just done instead but I really do think there is something to be had for a serial hybrid with electric type performance such as a Tesla rather than the current, rather meager, hybrids.

The UK will ban all sales of combustion engine cars and vans, including hybrids, in the year 2040.

 

The electric future is already laid out for us in England, that's assuming fuel cells don't make huge leaps between now and then.

 

The massive problem is it doesn't really solve anything as long as 85% of our electricity comes from coal & gas. It just moved the problem up the chain.

Not too sure about that. 0-60 in 1.9s is pretty nice. EVs are such a new technology and we’ll get even quicker acceleration soon.

 

I’ve had the joy to drive my family’s new Nissan Leaf, and compare it to a new Mini, it accelerates yarns quicker than a mini, and way more fun to drive.

Read up on EVs and cars in general

You might want to follow your own advice. I'm the guy that tows anything for my company, my truck has good low end torque and the best high end torque. My truck tows heavier trailers with little loss in performance and fuel efficiency. But it's also the lowest horsepower truck, only for the fact that diesel trucks red line at 3000RPM and gassers can go 4500RPM. I bought that diesel knowing that when it comes to towing, torque is king.


Yup the yup.

The fact that you think that there is something wrong with that statement, that somehow horsepower makes or breaks towing but torque doesn't, just tells me that like most car "enthusiasts," especially the ones on LTT, you're a rat rodder that only knows how to turn a wrench, not what turning that wrench will actually do.

 

Horsepower is the rate at which work is done.

Torque is the capability for work to be done.

Diesel vehicles are high torque, low horsepower, because they're low RPM.

Gasoline vehicles can be low torque, high horsepower, because they can safely achieve high RPM.

Electric motors are high torque at zero RPM, and as RPM rises, torque falls.

Electric trains use substantially larger and more powerful motors and the rails are powered.

Most are Diesel-Electric and have on-board power generation rather than powered lines, though both exist. A train is also well, exponentially freakin heavier than anything on the road and the prime reason electric motors are used is because of the torque performance. If diesel motors were better for that type of task it would be direct driving the train but that is not the case.

If you're above 90% RPM then you're also, or most likely, well above highway speed limits. There are actually many types of electric motors with different performance characteristics i.e. Variable Torque and Constant Torque.
