This time, we test-drove the numbered mass-produced models in the real world (on public roads). What are the “”similarities”” and “”differences”” between the new bZ4X and the new Solterra that many people are wondering about?
Toyota and Subaru together created the new bZ4X and the new Solterra
The first collaboration between Toyota and Subaru dates back 16 years (2006) to the commissioned production of the Toyota Camry at Subaru’s U.S. plant (SIA) (until May 2016).
Subsequently, although it is not well known, Subaru engineers were transferred to Toyota for the development of the Toyota “”Ractis”” and Subaru “”Tresia”” and carried out car manufacturing together.
This trend led to the joint development of Toyota’s 86/GR86 and Subaru’s BRZ, and now the new bZ4X and new Solterra.
Incidentally, the joint development of the new bZ4X/new Solterra differs from the tag teaming of the new GR86/new BRZ, which will be fully remodeled in 2021.
The development of the new GR86/new BRZ was carried out under the theme of “”Let’s build a good car together,”” with Toyota taking care of product planning and design, and Subaru taking care of development and production.
In the case of the new bZ4X and new Soltera, engineers from Toyota and Subaru were brought together in the new “”ZEV Factory”” on an equal footing, working from scratch.
From the planning stage to packaging, design, engineering, and equipment, the two companies discussed and developed the car together. In other words, it was a “”one-team”” joint development in the true sense of the word.
Although we in the media tend to focus only on differentiation, in fact, the common parts of the two companies also contain strong ideas and thoughts from each company.
Daisuke Ono, the person in charge of the development of the new Solterra, says, “”The ZEV factory was set up within Toyota for resource and production reasons, but there were no barriers in the development process that made us aware of the differences between manufacturers. When the result became a product, there were some differences between the new bZ4X and the new Soltera, but it would be better to say that we created a vehicle that both companies were satisfied with and seasoned it at the last minute to bring out the individuality of each car.
Looking at the two cars with this in mind, the image of the two models seems to have changed a bit.
One example is the exterior design. Some may say that both are “”too ordinary for a BEV,”” but the “”not too advanced, but not too conservative”” design makes sense when you look at them as models that are intended for widespread use.
Incidentally, the only differences between the new bZ4X/new Solterra are the color coordination of the front mask, rear combination lights, and wheels, as well as the different specifications of the cladding (material color for the Solterra and paint color for the bZ4X’s advanced version); the basic form is common.
However, it seems that it was difficult to reconcile the two companies’ particular needs, with Toyota wanting to emphasize design and Subaru not wanting to compromise on visibility performance.
Strangely enough, however, the new bZ4X has an atmosphere of a “”good mix”” of the two companies’ crossovers, skillfully balancing the wildness of Toyota’s RAV4 SUV with the sophistication of the Harrier.
On the other hand, the styling of the new SOLTERRA evokes Subaru’s new design language “”BOLDER,”” which was adopted from the second-generation Levorg, and it is clear that Toyota and Subaru’s respective design aspirations have been incorporated in the common parts.
The visor-less meters, horizontal infotainment, and the integrated structure of the center cluster and center console all seem to lean toward Toyota in terms of design, but the driver’s seat offers a good view (the A-pillar is narrow and the windshield wipers are hard to see), which gives the driver a sense of security and a functional layout. It is interesting to note that the sense of security, functional layout, and other aspects of the car that are not visible are typical of Subaru.
However, I wonder if it was not necessary to follow the many switches, which is one of the issues with Subaru vehicles.
Incidentally, the new bZ4X and the new Solterra have their own exclusive interior coordination, light gray and tan, respectively, and I was reminded that this is not mere differentiation, but an important element that enhances the “”character”” of each model.
The front seat position is more like a sedan with a high eye level than an SUV, but the “”top-mounted meter,”” which is installed for the first time in this model, looks over the steering wheel. This is a seat position that was adopted for the first time in this model. If we wanted, we would be happy if there was an adjustment allowance for this meter as well.
The navigation system is a new generation cloud type, but while the new Solterra is the best Subaru in terms of functionality, the new bZ4X has not only improved in some areas, but has been adversely affected in others, such as the elimination of screen splitting and simplification of functions. I hope that the new bZ4X will be updated to better accommodate users in the future.
The rear seat has more legroom than in other classes, taking advantage of the long wheelbase, but the floor is slightly higher, so the seating posture is a bit like sitting on a gymnast. However, there is plenty of leg room, so this is probably within the acceptable range.
One thing I noticed is that the new Solterra’s rear seats are equipped with heated seats, but the new bZ4X does not have such a feature. I do not think it was necessary to go to the trouble of differentiating between the two here.
250km range! Is Toyota and Subaru’s latest SUV, the bZ4X/Solterra, good-looking? What is the new EV with “”uniqueness””?
What are the differences in driving performance between Toyota and Subaru?
So how about their respective driving performance?
In this case, both the new bZ4X/new Solterra are electric AWD models (80kW + 80kW for a total of 160kW specification) with independent motors in the front and rear, and 20-inch specifications (Bridgestone Transa 235/50R20).
The powertrains are basically the same, but there are two differences between the new bZ4X and the new Solterra.
One is the number of drive modes, with the new bZ4X having two modes (ECO/Normal) and the new Solterra having three modes (ECO/Normal/POWER).
The other is regenerative control. Both have normal and one-pedal acceleration/deceleration modes (new bZ4X: Regeneration Mode / new Solterra: S-Pedal Drive), but the new Solterra is equipped with paddle shifters that can control the amount of regeneration in four stages in addition to the normal mode. The new Solterra is equipped with paddle shifters that can control the amount of regeneration in four levels.
Both of the Normal models have a “”margin”” of performance that slightly exceeds the expected value of “”this much power”” when the driver presses the accelerator pedal, but the new bZ4X gives a more powerful impression when compared to the two models.
We thought it might be an individual difference, but when we talked to the engineer, he said that the Normal of the new bZ4X corresponds to the POWER of the new Solterra, and the Normal of the new Solterra is relatively mild in taste.
Comparing the two vehicles, the POWER of the new Solterra felt more powerful than the Normal of the new bZ4X.
When we asked the engineer about this question, he replied, “”I don’t think that’s wrong; the two cars have different damper settings. Naturally, the car sinks differently when the accelerator pedal is pressed, so I think this slight difference in behavior is what gave the impression of a difference in power.
Paddle shifters are a common feature in engine-powered cars, but in BEVs they are used to adjust the degree of deceleration when the accelerator pedal is off.
There are four levels of deceleration. The default is “”2,”” followed by “”3″” and then “”4,”” which increases the degree of deceleration. On the other hand, “”1″” is equivalent to coasting.
This is a typical Subaru item in the sense that it leaves the control to the driver, but it would have been better if these were mounted on the new bZ4X without differentiating it from the other models.
Looking at the differences in powertrains, the new bZ4X is, at best, “”normal”” but, at worst, it is a bit too rational and lacks interest.
The footwork is exclusive to BEVs. The new bZ4X is called “”e-TNGA”” and the new Solterra is called “”e-SGP,”” but they are the same thing, just different names.
The new bZ4X is characterized by a low center of gravity, reduced moment of inertia due to reduced front and rear overhangs resulting from a more compact power unit, lightweight design, and an excellent rigidity-balanced body structure with a strong lower body and flexible upper body, resulting in excellent basic characteristics.
In addition to these features, the AWD model adopts electric AWD with independent front and rear motors. This is where the advantages of the fusion of Toyota’s electrification technology and Subaru’s AWD technology and joint development are best utilized.
The common features include a steering system with a solid core, a series of cornering performance that transcends the concept of a drive system, stability that seems to forget that the car has a high overall height, and a flavor that is sportier than it looks, but to be honest, the driving performance of the two cars is similar but not the same. However, to be honest, I felt that the two cars are similar but not the same in terms of driving performance.
The two differences in driving are EPS control and damper tuning. However, when you compare the ride, you can realize that the difference in ride quality is more than you can imagine, considering the parts that have been changed, though not as much as the new GR86/new BRZ.
Both are basically sporty in flavor, but the new bZ4X has a “”gentler”” steering feel and car movement, with a pleasant dullness as if a layer or two of skin had been added to the new Soltera, and a “”generosity”” that makes the car feel larger than the body size. It has a “”generosity”” that makes the car feel larger than its body size.
It is thinner than the new Solterra, but I thought it was more pure and faithful in terms of “”anyone can experience high performance without feeling self-conscious,”” which is a characteristic of Toyota’s driving style.
The ride quality of the new bZ4X gives the impression that the legs are moving more than expected, and in the practical range it is the most comfortable Toyota vehicle, but at high speeds, the car seems to move too much and is not under control.
In contrast, the new Sortera is “”agile”” in both steering feel and car movement, giving a direct impression as if a layer or two of skin had been removed from the new bZ4X. It has a movement that makes the car feel smaller than its body size.
In this sense, even without the horizontally opposed engine and direct-coupled AWD, Subaru’s unwavering axis of car manufacturing, “”enjoyment with peace of mind,”” is clearly reproduced, and it is a driving experience that will not betray existing Subaru users even if they switch to the new model.
The ride quality is slightly tighter than the new bZ4X, but it is also the most comfortable Subaru vehicle. It is rather flat at high speeds, but on the other hand, strange resonance is generated at around 70 to 80 km/h, and the lack of stability is a little worrisome.

How “”electric”” is the new bZ4X/new Solterra?
The Toyota Safety Sense (Ver. 3.0), the third generation of driving assist technology, is installed. Incidentally, the new Soltera calls it “”Subaru Safety Sense.
In addition to the accuracy/smoothness of control of ACC and steering assistance being at a level comparable to Subaru’s “”EyeSight””, the “”PDA (Proactive Driving Assist)”” risk anticipation support function and “”Advanced Park”” that enables automatic parking are also used, so Subaru fans should feel comfortable using it.
From Toyota’s side, however, the fact that the “”Lane Change Assist”” and “”Advanced Drive”” with traffic jam support functions, which will be used in the new “”Noah/Voxy”” models, have not been adopted may be a bit of a concern.
And the most concerning thing for BEVs is the “”cruising range.
The AWD + 20-inch model has a battery capacity of 71.4 kWh and a cruising range (WLTC mode) of 487 km for both the new bZ4X and new Solterra.
This public road trip was not fully charged, but started at about 80% capacity and traveled about 250 to 300 km, including general roads, winding roads, and highways.
Although the car can reach its destination even if it is driven as it is, Toyota and the company want the driver to experience the “”hardships (!?) of recharging the battery. The first day was spent driving from Shizuoka to Hamamatsu and back.
On the first day, we drove from Shizuoka to Hamamatsu, Hamamatsu to Nagoya, and on the second day from Nagoya to Gujo Hachiman and Gujo Hachiman to Kanazawa, and in all the sections, we found that the electricity consumption was around 6.0 km/kWh (we drove around 250 km each day).
When we spoke with Toyota’s CTO, Masahiko Maeda, he said that he was confident about the electric power consumption, so we had high expectations for the car.
When we talked to the engineer about this, he said, “”The 20-inch tire is more about maneuverability, so we are not ignoring electric cost, but it is also true that there is a part of the tire that has been cut off. If you value electric cost, 18-inch tires are probably the best.
Although the author was not able to ride in the test car due to the availability of a test car, a person who compared the 18-inch and 20-inch tires said, “”The 20-inch tire was around 6.0 km/kWh, but the 18-inch tire increased to 8.8 km/kWh.
We tried quick charging several times on the road, and we got the impression that charging for 30 minutes at 50kW output would increase the cruising range from 100km to 120km.

Looking at only the changed parts of the new bZ4X and the new Solterra, it may seem that there are no major differences, but when I actually drove them in the real world, the differences as cars were more than I had imagined.
However, when you sit in the driver’s seat and drive, the parts that you see are the same (the only difference is the emblem in the center of the steering wheel), but in combination with the ride quality, the new bZ4X looks like a Toyota and the new Solterra looks like a Subaru, which is surprising because they properly look like Toyota cars and Subaru cars, respectively.
The reason for this is that the point is rather in the common parts.
We did not add “”character”” to a car developed by either company, but rather developed the car together from scratch, so we were able to incorporate a good balance of both companies’ ideas in the common parts.
The differences between the new bZ4X and the new Solterra are like seasonings hidden in the common parts that bring out the individuality of each company.”
