Unanswered questions about new Prius

Toyota thought EVs were not price competitive with hybrids. They're right about that. But they didn't realize people were willing to drop thousands more for EVs.

 

That's the same for me. My life time is 5.2miles/kWh. I can get above 6 in summer and shoulder seasons, but winter average pulls down the number. The PP is officially rated to be only 4miles/kWh by the EPA rating. Average 5miles/kWh is already above that mark. I don't know if M3 can average that high with highway drivings included which I never do with my PP on the EV.

it will take a major catastrophe for mankind to realize this.

 

My 5.1 is about half-and-half city/highway.

 

Name a well-built hyper-efficient EV liftback.

 

there isn't a good ev for most folks yet. compromises must be made in most cases when people do buy them.
a prius ev sounds good on the surface, and i would like one if it met my needs. but there have to be good reasons why toyota hasn't made one, and as far as we know, is not contemplating it.

 

An article I read in the 90s was entitled, "It's the battery, stupid!".

That.

 

and they were probably right. toyota is maybe the furthest behind in battery technology, access to raw materials, and manufacturing capacity.
that can change quickly though, and we might see good things in the near future.
one concern i have is that manufacturers don't see efficiency as a plausible marketing tool

 

Nope, it's all about zoom zoom, 0 to 60 time, and being the fastest moron on the road.

 

The thing is that your definitions of city and highway driving are probably different from mine. In my scenario, my driving is 70% rural 29% interstate (above 65mph), and about 1% real congested stop-and-go city drive. This percentage is by the distance traveled, not by the number of trips. If done by the number of trips, then it would be 99% rural and less than 1% each for interstate and city drives.

My routine rural drive is almost no stop-and-go traffic but speed varies from 25mph to 55mph depending on the road I am on. I use my PP's EV mode for those, but never on the interstate where the speed exceeds 65mph.

 

My definition is about 50% 25-45 in-city, and 50% 55mph in-city highway.

 

The Ioniq Electric was as efficient as the Prius Prius, or better. It started under $30k. Those numbers shifted a bit when the car got a larger battery. Hyundai has greatly improved since my friend got a 2000 Tiburon.

Now that Ioniq is an EV sub-brand, going to have wait for a direct replacement to the original.

Maybe you can import one of those hydrogen Prius when they arrive.

 

Full H2 cars are just as dumb as full battery cars.

But we're stuck with full battery cars now, so we have to try to make the best of them. Let's hope for some serious battery improvements into the 800Wh/kg and $30/kWh range.

 

Don't you drive above 65mph on the interstate? In my case, less than 1% of trips by numbers are on the interstate, but by distance, it represents ~30% of total miles driven on my PP. I never use EV mode for those interstate trips.

My question was "Would M3 or any other BEV, which would be used for the trips on the interstate going above 65mph, get efficiency as good as PP's EV efficiency on non-interstate speed (below 55mph). I doubt it. But, this also means that if I drove my PP at a speed above 65mph 30% of the distance driven on the EV mode, I really doubt I can maintain the lifetime 5.2 miles/kWh average efficiency.

 

In-city highway, the speed-limit is 55, and I don't speed.

Speed kills efficiency. Aerodynamic power goes up with the cube of speed while distance covered is just linear. So, aerodynamic losses go up with the square of speed.

Speed doesn't change efficiency caused by rolling friction, since it's linear with speed, as is distance covered.

 

You are lucky, no interstate highway driving for your PP. If I can do that then I am quite confident that I can get very similar EV efficiency on some of the BEVs available on market. Yes, speed kills efficiency, but when traveling on an interstate, there are sections that have a minimum speed of 45 mph, but in reality, it can be dangerous to drive below 55 mph on most stretches of the interstate I drive. So, I adhere to the speed limit and flow of the traffic which makes above 65mph on the interstate a regular thing (at least ~30% of distance) on my PP. Again, the point is that I really don't think PP or any BEV would get overly optimistic efficiency above the EPA rating in those instances.

 

We've got two routes into town: a secondary highway with speed limit 80 kmh, and the freeway, which has 90 and 100 kmh limits. Haven't taken the freeway in over a decade, lol.

 

Not quite 'hyper' efficient, but the Model Y 2wd is reasonably efficient.

 

You would see 6 mi/kWh round-trip on the Prius Prime only if you drive 25–35 mph. I exceeded 7 mi/kWh round-trip a few times, but that's even more hypermiling than driving 25–35 mph, sticking closer to 25 mph.

However, thin mountain air in Colorado reduces the aerodynamic drag and improves the fuel economy, but cold weather would negate this effect by making air more dense.

 

No it's not, and it's exceptionally over-priced ($20k or so). And no dash, and lousy quality.
