EV owners of today and tomorrow

From what I’ve read, it is, essentially, a pure EV. An AWD EV with a V6 “portable” generator onboard.
They’re claiming 145 miles range on electric. Assuming that’s true, many could charge daily without using the gasoline engine? If so, the drawback over a standard EV , would be the weight of the engine, and initial price tag, but it does give a high >700 miles range, which many should like

The tiny BMW i3 REx serial hybrid got 30 MPG. A larger Prius gets an easy 50 MPG.

GMC has an extended range package for the 2025 Sierra Denali. It extends the range from 390 miles to 460 miles. Not sure the $9,500 cost is worth it. I hope the seats are comfortable. According to my wife I would be sleeping in it if I brought one home.

I did not tell the wife about buying the Tesla until she was driving me home from the Hospital. Fortunately I did not have to go right back into the emergency room after telling her.

I may already be regretting that post. I firmly believe the the engine should be able to drive at least one pair of wheels in certain conditions, which apparently the Ramcharger cannot. That ability could help when pulling a trailer up a long grade etc.

Electric motors are awful torquey. What do you see as the advantage of a direct connection to the ICE? I'm thinking what has worked well for diesel locomotives and submarines the last 90 years must work well enough for towing any trailer I own.

Standard PHEV model? All the performance advantages, but also usually the most expensive configuration, as you're essentially adding an ICE generator to an already expensive BEV.

A big problem with early homebrew EVs was using an industrial motor and motor controller, and not spinning the tires off the line every time.

In a locomotive application shifting gears with a mechanical gearbox is totally impractical so the inefficiency of converting mechanical power to electrical and electrical back to mechanical is energy well spent.

The diesel-electric locomotive's ICE drives an excited field alternator whose field is controlled to regulate power driving the traction motors. There may be a couple stages of excited field alternators serving as amplifiers so one might use a small rheostat flowing a few amps to control hundreds of amps out the big alternator.

And then there are the other great efficiencies of steel wheels on steel track and no stop signs or traffic lights. IIRC they claim 400 miles/gallon per ton of cargo.

The PHEV adds a potential (not always used) electrical to chemical and chemical back to electrical path for more losses.

Plug-in Hybrid adds all the complexity of BEV and ICE.

It is the magic of planetary gears and electric clutches. You use all the EV motor power And can planetary couple the engines output in addition "when" needed.

Is a serial hybrid. The least efficient means of implementing a hybrid. Mechanical energy from engine converted to electricity, most stored in battery some used immediately on motors, then later used from battery. Not as efficient as directly driving the wheels from engine.

This is just the sort of solution that sounds attractive to intellectuals who sit in their mother's basement "thinking" about things but never actually getting up to do something and get real experience.

Some will say it is no different from a pure battery-electric vehicle whose electricity comes from natural gas, oil, or coal fired power plants. The difference is those large stationary plants are more efficient, and cleaner. Plus the BEV can be powered from solar, nuclear, hydro, etc, if one cares about such things.

Well guess what it sounds like an attractive idea to me.

If the RAM was out I'd certainly be considering it. And I like the Edison system and feel that it is a very practical system. It gets the"simplicity" electrical axles and a good sized battery for the initial run with the ability to recharge at any time needed or desired.
An electric drive capable of starting loads and moving them with the efficiency of electric and the capability of recharging when needed.
The ability to use much more energy when starting and working and then to conserve energy will loafing along on flats or downgrades.

You are entitled to your opinion but that is all that you are spouting off about your opinion and only yours.

That is the Toyota Synergy Drive system. Toyota found it terribly hard to control with software but prevailed.

Ford licensed by sharing clean diesel technology. Licensed the right to build their own, did not license a copy of Toyota’s work. Doesn’t seem to be using in their PHEV truck.

Notice RAM is only claiming maximum range and not saying anything about energy consumption? Is going to be awful. You get your pipe dream of an onboard charger but it’s use will come at a high price.

First Volt prototype was a series hybrid. Fuel economy sucked so bad the project was delayed nearly two years in a panic building a transmission.

BMW i3 REx was a pure serial hybrid with terrible fuel economy.

You keep dreaming but never wonder why your ideal simple solution is (almost) never brought to market?

 

[WinterDeere]

...not saying anything about energy consumption? Is going to be awful.

I doubt RAM is putting fuel efficiency anywhere near the top of their priority list, having built a customer base almost solely on large-displacement engines.

All else equal, of course I'd choose the vehicle with better efficiency. But "all else" is never equal, and so I drive vehicles that consistently get less than 15 mpg.

Volkswagen Data Breach Exposes Location Data of 800,000 Electric Vehicles - Security Spotlight

A data breach at Volkswagen has exposed the location data of around 800,000 electric vehicles from VW, Audi, Seat, and Skoda. The vulnerability, reported by the Chaos Computer Club, allowed potential linkage to driver identities. Volkswagen maintains no misuse has been detected.
