Seeing a sleek modern car pull away whisper quiet and then start the ICE 3 seconds later with a stutter and a puff of water vapor from underneath is the most schizophrenic sight, it somehow feels more dated than actual ICE cars.
Unless you live in bumfuck nowhere with expensive electricity, zero solar power and a daily 5 hour commute, an EV will likely work just fine for you.
I’m a few years into PHEV ownership now, and I’m so glad I didn’t get an EV. Just a normal weekend trip to the beach or mountains (200-ish miles from the Triangle of NC either way) would mean I’d have to limit myself to hotels/Airbnbs with a charger. And chargers are VERY sparse everywhere I’ve been.
With my RAV4 Prime, I get 40-50 miles of EV range, enough that most days I use zero gas. But if I want to hit up the beach or mountains, or take a cross-country trip, or drive up to PA or VA to visit my girlfriend’s family, there’s zero hassle to find a charger. It just reverts to a normal hybrid once you run out of electric-only range (around 20% of the battery’s actual capacity).
It also performs far better than any EVs or ICEs I’ve seen anywhere close to its price point.
This “everyone should just have an EV” thing really reads like a modern “let them eat cake.”

My own anecdote is that I vastly prefer driving an EV on road trips. The lack of noise and gear shifts, regen braking, etc., all make it a much less draining experience.

This is a very different story for countries that don't have high import tariffs on Chinese vehicles. EVs there are fast becoming the cheaper option.
However, as someone who made the jump to an EV a few years ago, if you can manage it it's more reasonable than a lot of people think. I too live in the Triangle of NC, and my current EV cheerfully gets me to the beach every year and up to visit family in Virginia without breaking a sweat. This year, I used ABRP (A Better Route Planner app) to plot out the beach drive and it was as smooth an experience as I've had making that trip. Yes, we had to stop for a charge (because I hadn't charged fully before we left), but I had the chance to grab a snack and stretch my legs for fifteen or twenty before setting out again, so I honestly didn't mind. A lot depends on where people need to go, but thus far I haven't found a lot of places where the chargers are so sparse I really had to worry about it.
Curious what you're using for comparison for "performs better." There are lots of 300-400+ HP EVs when you consider the cost of a RAV4 Prime ($41.5K-$50K USD)
If we put aside 5 hour commute, this describes central Tokyo, not bumfuck nowhere. Bumfuck nowhere has land for offgrid solar and therefore free home charging.
If the city you're in offers free roadside parking with L1 or L2 charging on light poles, good for you, but Tokyo and Japan at large isn't like that at all(unattended roadside parking is banned nationwide and robotic garages are everywhere).
> robotic garages are everywhere
Robotic WHAT? That's crazy, if it's what I'm imagining. Is Tokyo that much crowded?I have an EV, which is amazing in my metro area, but I regularly take trips where I would not feel comfortable finding a place to charge, despite what EV locator maps might tell you. If you show up and that charger is not working, which is not uncommon, you might be stranded.
But I’m not even sure regulators would allow such a design. Even then I’m not sure it’s worth it.
But I am totally done with ICE car maintenance. I want nothing to do with it anymore.
I believe there's also a bunch of Chinese vehicles with similar design, entirely electric drivetrain with gas generators for range extension. Most of these will need to kick in before the battery is empty so that there's some stored energy buffer available for acceleration.
Hmm. Supposing we need a 6 hour drive at 20 kWh per hour (eschewing specific speed/distance figures), and a generous "smaller battery pack" can provide 3 hours (60 kWh). Then the generator must supply the missing 60 kWh during the 6 hour interval, i.e. a 10 kW generator.
Google says those cost from 1k to 5k USD, and they seem rather beefy.
(Just doing the math out of curiosity, otherwise agree with you.)
Hook it on, plug the connector up and attach your license plate to the back (or use eink).
It's not exactly what you're describing, but I think it will become more common as battery technology growth slows down.
A more practical solution is to just rent out a small generator on a trailer.
Unless I’ve completely misunderstood what you’re getting at.
Hybrids with their good mileage although complex are a good fit for those.
It almost reminds me of mechanical alarm clocks from the 70s, where they are designed to look like an electronic model but are just driven by AC motors (1).
The smaller size of an EV would be more useful in most European cities, at least.
tl;dw: constant RPM and a weird stroke geometry where the power stroke is longer than the other strokes to extract more energy from the expanding gasses.
A.k.a. Atkinson-cycle (1882): https://en.wikipedia.org/wiki/Atkinson_cycle
I think it's also because EREVs need a performant generator that isn't much different from the drive motor. So you'll have a full ICE+EV drivetrain on top of an EV as its battery for it to work, which is not ideal.
Compared to that, other hybrid systems like the motor-clutch combo packs that sit between the ICE and gearbox, as well as the fixed gear Toyota systems, can have motors that are weaker, lighter, and cheaper than the ICE, while being able to be additive to the ICE power output. That makes more efficient use of steel and copper than full serial setups.
BMW i3 had such EREV option, but it apparently used a cheap OEM bike engine(not like a BMW Motorrad engine) and also could not overcome power draw of the EV drive motor. So it literally just extended the range, not allowing it to run indefinitely at highway speeds with just refueling. Nissan e-POWER system is powerful enough to do that, but then the readers of comment will have to back to the line 3.
More recently effort is also going into series hybrids for public road haulers, which I personally think is a great application for it since you can potentially put a lot of the equipment into a hot-swappable dolly.
I drove a Nissan Note (Nismo esition) with ePower and it could happily spin the wheels when taking off, not something you normally get out of a tiny economy hatchback. I think it has 140kw electric drivetrain? 140kw is pretty sporty when delivered instantly.
Now these EREVs are mostly luxury niche of big cars (where extra space taken by two power trains doesn't matter) for people who don't want to spend 20 minutes at rapid chargers on that yearly long trip they do. Or for people who live in some global warming ignoring backwater[1] that hasn't built out rapid charger yet.
[1] even China has ubiquitous fast charging network now
Nissan has been really struggling for the last few years, this new hybrid engine doesn't look like it will turn things around for them to me.
EREVs are an idea that is not new and also relevant in shipping and aviation. Many modern large ships (oil tankers, cruise ships, etc.) are already EREVs effectively: an electrical motor drives the propeller and a generator powers the motor.
And there are are a few plane designs that are using small batteries + generators to power flight. It makes a lot of sense: electrical motors are a lot simpler, lighter and cheaper to maintain. Engine maintenance is very costly in aviation. And so is fuel. The recently announced X1 is a good example of a plane that does this. There are a few other manufacturers working on this as well. Early days but the potentially large fuel savings probably ensure this is going to happen one way or another.
The simples reason is this. What you’re describing is having a gas motor spin a thing (the generator) -> charge battery -> discharge battery -> spin a thing (the wheels) to make car go. Each of those steps has efficiency losses.
That’s why most hybrids are parallel hybrids, where both the gas engine and the battery+motors can spin the wheels more or less directly, even at the same time.
you still basically get the engine spinning at a more constant rpm, and the battery kicks in for acceleration (and charges on deceleration), and now highway cruising doesn’t have any lossy conversion steps, while acceleration and braking uses the advantages of the electric drive chain.
And yes the Atkinson cycle helps
>>EREVs/series hybrids don't get better fuel economy
They sure do if 80% of your driving is done purely on battery, which is how nearly every Volt owner I know operates. Once every couple weeks they'll exceed their EV range, let the gas engine take over, and be done with it. The fuel is sipped so infrequently the car will require a "maintenance mode" to run fluids through the ICE but the car is still perfectly useful for a last minute blitz to St Louis or whatever.
I love the Volt. I personally have an i3 REX and I love it even more because it is absurdly lightweight and RWD.
>>Just get an EV
What about renters who don't have access to level 2 charging? The small battery in an EREV can be easily topped up with a normal extension cord (20 amp rated) run out of a rented house or apartment to the car.
Alternately, what about people who can only afford or have the space for one car? Not everyone wants to own the small city EV + ICE road trip car wombo combo, nor do people want to spin the roulette wheel of charging infrastructure that is still barley adequate, especially in the flyover states.
A Chevy Bolt EV gains around 5 miles per hour when charging at 12 amps from a 120v socket; it's similar to an i3 in this way.
If it's home half of the time and it sits plugged in for 12 hours every day, then it it can gain ~60 miles during that time.
60 miles per day is not enough to cover everyone's needs all of the time, but it's more than enough for all kinds of folks who would otherwise be afraid of having some kind of electrical upgrade required before considering an EV.
For comparison, the full classic gasoline engine with manual gearbox consumes less gasoline than the e-Power one. This is just some pure greenwashing, that isn't even explained at car dealerships and people can't say anything about it, when you ask for information.
Works like (?) an EV, it isn't an EV.
You surely mean that it is not recognized as plug-in hybrid vehicle.
10L/100km on highway, worse than cheaper comparably powerful ordinary diesel. Seems like a pointless car, X-Trail 2.0 dCi M9R was better in every possible way.
I'm not familiar with this; don't you just plug it in?
- Nissan's petrol engine is the crossbow, a well optimised generator for onboard battery
- Every other brand's EV is the machine gun. About 4 times as energy efficient as a petrol car when you take into account the lifecycle of the vehicle, so probably more when you talk about a hybrid car.
Why bother going to all this effort for an internal combustion engine (crossbow)? Why not spend that money researching 100% EV (machinegun) drive trains?
Its pretty obvious where the future is headed for personal vehicles (yes yes yes I am sure I will get loads of responses where people need to drive 750 miles a day non-stop every day, both ways, towing a boat, up a mountain etc).
It surprises me that these manufacturers like Nissan and Toyota and Honda seem incapable of reacting and changing their product line-up. You can get 100% EV porsches, mercedes, BMWs - hell even Range Rover now and yet these guys are dithering and have basically got only very very half-hearted efforts in EV offerings while apparently trying to pretend its not happening and relying on hybrids.
Meanwhile, at least here in London, I am seeing more and more and more EV BYDs & Jaecoos & MGs etc... so if you care about outward appearances you buy the merc/porsche/etc EV, if you just need a car and don't care what people think you buy the cheap & decent Chinese EV. Toyota, Honda et al don't compete at the luxury end, and they've got nothing to compete with against Chinese EV brands who seem to be taking over the lower end where Toyotas and Nissans etc used to be popular.
