Subaru's Own EV Drops Toyota. Should You Wait for It?

If a Subaru electric vehicle (EV) is on your list this fall, every one Subaru has sold so far was developed with Toyota: the Solterra, the Trailseeker and the Uncharted. On Saturday, October 17, Subaru let reporters drive the first EV test car built on its own technology, at its research center in Sano City. Electrek reports that Subaru revealed the technology the next day, Sunday. Electrek reports that executives said some of the new technology will begin rolling out around 2029, while CarExpert and Headlight.News report the first showroom model from 2029. Subaru did not disclose the battery capacity, the driving range or the charging speed, and it cautioned that the test car does not represent final production specifications.

So the question for a shopper is narrow: does a prototype with no published price or range change what you buy this year? Mostly not, and the reasons are below.

What Subaru showed in October

The package is Subaru’s first dedicated EV platform plus new batteries, new electric motors and an integrated control unit that enables over-the-air (OTA) software updates. The camouflaged test car wore the body of an Outback, modified for the new platform’s longer wheelbase, and Subaru said the design is not final.

Two of the bigger numbers are Subaru’s own, not independent measurements. Its engineers say the motors are 30% more efficient than the industry average, and Subaru is aiming for battery energy density 20% above the industry average. Neither figure names the average it is measured against.

The Japanese magazine Motor-Fan, which drove the car on Subaru’s handling course, reports that it is the test vehicle for a production version of the Performance-E STI concept shown at the 2025 Japan Mobility Show and pictured above. Subaru told Motor-Fan it had built the car in half the usual time, and that full tuning was still to come. Headlight.News reports that Subaru confirmed the production version will be slightly larger than the Outback.

Takatomo Watamori, Subaru’s executive officer in charge of engineering, put the reason this way to Automotive News: “By developing vehicles in-house and having EV technologies on our own, we can quickly deliver to our customers the peace of mind and driving pleasure that define Subaru, even in this era of change.”

Postponed in May, but never stopped

The October news reads like a reversal, because five months earlier Subaru had pulled back. In its May results presentation, Subaru said it had “decided to postpone the launch timing of in-house BEVs and to shift development resources toward expanding the ICE and HEV product lineup”, meaning battery electric vehicles (BEVs) gave way to internal combustion engine (ICE) and hybrid electric (HEV) models. The same presentation recorded 57.8 billion yen of BEV-related expenses, including an impairment on capitalized BEV development costs, in a year when operating profit fell to 40.1 billion yen.

Electrek reported at the time that Subaru had planned up to four of its own EVs by 2028, built at a new factory at its Oizumi plant, and that the factory would open building gasoline and hybrid cars instead.

But the May presentation also said: “Development of essential future technologies, including batteries and eAxles, will therefore continue.” An eAxle combines the motor, inverter and reduction gear in one unit. Another slide in the same deck lists “Continue R&D towards future full-scale introduction of BEVs.” Read against those lines, October looks less like a U-turn than the research track May kept. It also goes further than batteries and eAxles: Motor-Fan calls the car a prototype built in one year of digital development, and the 2029 showroom reports point to a vehicle program, not only parts.

The larger goal is less clear. CarExpert reports that Subaru still wants EVs to be half of its global sales, but now expects to get there after its original 2030 deadline. In May, Electrek called that 2030 target “effectively dead.”

What it means if you are buying a Subaru EV now

The cars Subaru sells stay Toyota-based. CarExpert, an Australian outlet, lists the Solterra as closely related to Toyota’s bZ4X, the Trailseeker to the bZ4X Touring and the Uncharted to the electric C-HR. In the US, the bZ4X is now sold as the bZ, and Headlight.News lists the bZ Woodland as the Trailseeker’s Toyota counterpart. Prices below are the manufacturer’s suggested retail price (MSRP) from Subaru’s June and July 2026 pricing releases, before destination and delivery.

Destination and delivery adds $1,525 on the Uncharted and the Solterra and $1,545 on the Trailseeker, more in Alaska. Subaru’s April reveal said the Getaway would reach retailers in late 2026, but Electrek reported in September that it now arrives in 2027 as a 2028 model, and Headlight.News also says it joins the lineup next year.

Four facts decide whether waiting makes sense:

1. 2029 is a target, not a promise. Electrek reports no specific launch date was given. The 2029 showroom date comes from CarExpert and Headlight.News, and no outlet reports a model name or price. Electrek counted May’s postponement as the second time in six months that Subaru pulled back from its EV commitments.
2. The first model sounds bigger and quicker than the current cars. Subaru said the production version will be slightly larger than the Outback, and Motor-Fan describes a concept packaged around its occupants, rear seat included. CarExpert notes the prototype’s under-4-second 0 to 100 km/h claim beats the 4.4 seconds Subaru claims for the Australian Trailseeker; Subaru of America rates the US Trailseeker at 4.3 seconds from 0 to 60 mph, a slightly shorter sprint. That is the honest case for waiting.
3. The new electronics reach gas and hybrid cars too. Subaru said it will deploy the integrated electronic control unit (ECU) gradually across its lineup and standardize electronic platforms across electric, hybrid and gasoline cars. It plans software-defined vehicles, cars whose features can change through updates, in the second half of this decade. That suggests the new control unit is not tied to the EV’s launch date.
4. Subaru is not adopting Toyota’s software, for now. Subaru said it has no plans at present to adopt Toyota’s Arene software platform, despite Toyota’s 21% stake in the company. Reuters reports that Subaru developed the chip at the core of its control unit jointly with Advanced Micro Devices (AMD).

The practical reading, which is this site’s opinion rather than anything Subaru has said: if you need an EV in the next year or two, the choice is between the Uncharted, Solterra and Trailseeker (or the three-row Getaway once it arrives) and their Toyota twins, on price, range and dealer. A three-year lease signed now ends in late 2029, at or before the earliest reported date for Subaru’s own model, so it keeps that option open but may need an extension if 2029 slips. If your current car is reliable and you can wait until the end of the decade, watching costs you little. To compare the Subarus with every other EV on sale, the EV catalog lists them alongside the rest and the EV Matchmaker scores them against your budget, daily miles and climate; the new electric cars tracker follows announced models that are not on sale yet.

Why Subaru is doing this at all

Subaru is small next to its partner. It sold 923,873 vehicles worldwide in 2025, less than a tenth of Toyota’s 11.3 million. It wants 1.2 million a year in the first half of the 2030s. Motor Illustrated reports that wider use of common components and in-house electronics is expected to help contain costs as Subaru grows. Reuters reports a target of cutting vehicle development times by about 40%.

The case against reading too much into October is the May presentation itself, which moved development resources toward gasoline and hybrid models. The prototype shows what Subaru can build. It does not yet show when Subaru will sell it.

Subaru in-house EV questions

When will Subaru’s own EV go on sale?

Subaru has not given a specific launch date. CarExpert and Headlight.News report the first showroom model from 2029. In May, Subaru said it had postponed the launch timing of its in-house EVs.

Were the Solterra, Trailseeker and Uncharted developed by Toyota?

They were developed with Toyota. CarExpert lists the Solterra as closely related to the bZ4X, the Trailseeker to the bZ4X Touring and the Uncharted to the electric C-HR.

How powerful is Subaru’s in-house EV prototype?

The test car makes 380 kW combined, about 510 hp, from a 150 kW front motor and a 230 kW rear motor, and Subaru claims 0 to 100 km/h in under 4 seconds. Subaru did not disclose its range or battery capacity.

Who makes the battery cells and motors?

Panasonic Energy supplied the 4,000 cylindrical cells, and the drive units were developed with Aisin.

Will Subaru use Toyota’s Arene software?

Subaru said it has no plans at present to adopt Arene. Reuters reports that the chip at the core of Subaru’s own control unit was developed jointly with AMD.

Should I wait for Subaru’s own EV instead of buying a Trailseeker or Uncharted?

Only if you can wait until the end of the decade. The 2029 date comes from press reports, not a named model with a price. The 2027 Uncharted starts at $34,995 and the 2027 Trailseeker at $39,995.
