We've created a comparison table of the number of years it takes to pay back the fuel costs of hybrid cars, PHVs, and EVs!

We've created a comparison table of the number of years it takes to pay back the fuel costs of hybrid cars, PHVs, and EVs!
First of all, a serialized article was published in the Nikkei Home Builder issue that arrived yesterday.
The title is "Poor insulation performance makes you hate air conditioning?"

Today's main topic is, how much do eco cars cost? We've looked into this question in detail and here are the results.
This is a summary.
I drove both the first-generation Prius (which I bought used) and the second-generation Prius for over 2 km each.
We still have two Prius cars with 23 km on them in our office.
(One was a used car purchase and the other was a new car purchase)
Recently, we had a self-employed customer who was spending a lot of money on gasoline.
This was inspired by the advice I received.
In creating this table, we have tried to calculate fuel economy based on actual fuel economy as much as possible, rather than catalog fuel economy.
We also took into account the availability of subsidies, mileage, and preferential tax systems.

You probably won't find a table with such detailed comparisons in any car magazine or on the Internet.
Indeed, if we look at fuel economy alone, the regular Prius is about 10 times faster than a car with a fuel economy of 2.5km/L.
The Leaf is seven times cheaper.
However, the Leaf's actual driving range is said to be around 130 km, making it difficult to say it is practical.
I've also heard that the heating doesn't work very well.
Plug-in hybrids are expected to become more common in the future, but currently they are only good for about 24km.
It can only be driven as an electric vehicle. For those who usually drive around town and only go on long trips on weekends,
The effect will be great, but for people who usually travel a lot, the benefits are not so great.
I understand.
By the way, let's look at the table to see how much profit I've made from the three Priuses so far.
Saw.
The first generation Prius probably had 20km on it during my generation, 10 years and about 180 million yen.
Bought a second-hand second-generation Prius with 2km, 15 years and about 7 million yen
A new second-generation Prius with 2 km and 20 years worth of goods costs about 10 million yen.
This amounts to a savings of approximately 480 million yen.
Of course, gasoline was cheaper 15 years ago than it is now, so if you take that into account, it would probably be around 400 million yen.
I think it saved me money.
In addition to the profits we have made, there are other benefits. Most people don't know this, but
Only Prius cars with mileage of 40 km can be traded in for 10 to 20 yen.
You can have it done!!
If you don't care about style and you only care about economy, there is no better car than this.

However, after recalculating, it turns out that plug-in hybrids do not save as much as we thought they would.
That was surprising. Electric cars were what I expected, but...
There are many ways to save money and make investments, such as solar power generation, improved insulation, and winter solar radiation capture.
Items such as protection from the summer sun and reducing fuel consumption in cars are far more certain and will generate higher profits.
Today's solar power generation can easily exceed 10% in terms of yield.
It's going to be expensive.
What do you think when you look at this table?
