This. This times 100x . Also, it’s not like each powertrain has an independent failure mode. If either break, your car is a brick until it’s fixed.

I have a friend who drives a Chevy Volt with a dead ICE engine; she just charges the battery and uses it as a (rather short range) pure EV vehicle. Not ideal, but it works for her until she gets something else.

If she was in California she wouldn't be able to pass smog at her next inspection, which is a funny problem considering she drives in pure EV mode now.

See the Ioniq 5 N. But those sounds are piped inside... not blasted to the neighbors...

I love the look of the Ioniq so much, I wanted to reward the guts it took to create such a unique looking car! I wanted to buy the new one but I just couldn't not get a Tesla because of FSD. Cars without FSD are fighting for second place imho.

I like Hyundai's HDA much more than Tesla's.

With Tesla it's all-or-nothing, and when it inevitably drives poorly, I can only turn it off. It physically resists me turning the steering wheel while it's driving, and overcoming the resistance results in an unpleasant and potentially dangerous jerk.

OTOH in IONIQ I can control lane assist and adaptive cruise control separately. The lane assist is additive to normal steering. It doesn't take over, only makes the car seem to naturally roll along the road.

>> the range extender was unable to recharge the battery Could you expand on this? What was the actual problem? For example, did the range extender start and run? Did it put any energy into the battery at all?

The original BMW i3 had/has a lockout that prevented the range extender from charging the battery until it reached 6% in order to meet California's ZEV BEVx regulation.

facepalm

I don't know what to call this.

I don't touch the steering wheel period in my Tesla though. Literally from door to door.

Another part of the point is that you can pack a much smaller and more efficient ICE and then substitute the missing power and torque from electric motors when needed. Most cars are not used at max power all the time. You need max power only at short times when accelerating. With pure ICE there is the tradeoff - a bigger engine will get you more max power / max torque but is going to be less fuel efficient because of…

On paper, yes, but did that ever happen? Sorry for being sarcastic, but where I live the frugal hybrid is exceptionally rare and the "same big engine, but driving a much heavier car" hybrid is omnipresent. The kind of people who might buy the frugal one buy second or third hand while almost all buyers of factory new pick the "same big engine" option, and those are the ones who decide what's available on the second ha…

I've never seen a car where the hybrid and pure gas versions have the same size engine; the hybrid engine is almost always lighter and makes less power.

The difficult is not electricity prices; those can simply be tariff'd for overhead-slash-profit as all U.S. chargers do already. The difficulty is building out hundreds of chargers within a single city block's worth of the city's x,y grid. That level of power density is generally only seen in heavy industrial zones, and residential distribution grids can barely cope with air conditioners, much less with electric vehi…

This doesn't really matter that much. The average car commute in the US is less than 40 miles per day. Even if we assume that everyone gets a fairly giant Model X, that's still around 12kWh of energy per day.

You can get that much power from a regular 120V wall plug within 8 hours.

Which is why I'm surprised electric cars with range extenders aren't a bigger thing: * https://en.wikipedia.org/wiki/Range_extender Have the powertrain be all-electric, and have a battery pack, but for those with range anxiety have a small generator as an option that woul…

The EU2200i can sustain 15 amps. That charges most EVs at something like a few miles of range per hour. The biggest one that’s small enough for a frunk is the 3200i, which still only sustains 21.7 amps - plus, that’s from an L5-30R socket, so you’d need an adapter for the EV, and a custom chip to limit charging current below that, since the ones I’ve seen for that socket assume they can pull 24 amps.

Ah, thank you, I see the argument. I'm still a bit skeptical though when many non-CVT automatics are 6 or 8-speed models that there would be much "sweet spot" benefit left by being able to make relatively small changes in engine speed. Like many things probably depends on exactly what comparison is being made.

I mean, we are comparing 6-8 to effectively infinite? Question then comes into just how much is lost by being outside of the sweet spot for an engine. Which, I agree that I would not have thought it would be that big of a deal. Just going off modestly paying attention in my car, I see massive benefits keeping the car around 300 rpms lower. Interestingly, my car gets better gas mileage around the 40ish speeds than I d…

Generally speaking your car will get better fuel economy at 40mph than it will at 60 or 70mph. Your car gets so much more wind resistance the faster you go.

The main reason why city mileage is usually lower is because of all the stopping.

Cool idea. Perhaps a better idea would be to borrow from the brake balance adjustment in race cars, wherein an adjuster dial/knob allows the driver to alter the balance between the front vs rear brakes when the brakes are applied (very useful in wet vs dry conditions, high-speed vs low-speed sections, etc.). So, instead of adjusting the F-R brake balance, the dial could adjust the regen-vs-mechanical braking, up to t…

Most of the dynamics like that are abstracted away in EVs (i.e. dumbed down) or buried in menus and not readily accessible. I think this is done in part because the majority of people don't know or care about them, and if they were readily accessible would toggle them unknowingly and be confused or upset. In the Nissan Leaf it was done intentionally to make the car feel as much like a traditional ICE as possible. In…

>>the dynamics like that are abstracted away in EVs (i.e. dumbed down) or buried in menus and not readily accessible.

Exactly, they already do regen first, then mechanical braking, and just hide all the details.

I would like to see those details available so I can tune them (it'd be ok if they put safety limits on where they know the capabilities of the batteries, electronics, etc. far better than I ever could). Just a nice to have...

Everytime I fill my truck up, I’m at the gas station thinking “man, I wish I could just hang out here for two hours!!”

I’m keeping my Tacoma forever

Used vehicles are about to be where it is at.

The tracking, the module security lockdown, and that in a couple years particulate filter systems like DEF for diesel that everyone just loves… is coming to petrol by regulation.
