The new Honda Super-One taps into a growing appetite for retro-flavored EVs, borrowing heavily from the irreverent charm of the City Turbo II from the ’80s. While the standard model already leans into a sporty aesthetic, Mugen has taken it further with a more aggressive bodykit, interior tweaks, and a set of performance dampers to back up the look.

Starting with the exterior, the Japanese tuner injects a dose of motorsport attitude into the Super-One. Up front, it gains a black chin spoiler and a vented hood, but the real standout sits along the sides, where vented wide fender extensions are mounted over the already flared arches.

Those arches are complemented by carbon mirror caps, deeper side skirts, and a set of 16-inch forged aluminum wheels with a five-spoke design. Around back, Mugen adds a sizeable roof spoiler and sharper extensions to the rear bumper.

Inside, the front seats have been swapped with semi-buckets from Recaro, complementing the track-ready stance. Buyers can also get special floor and luggage mats, scuff plates, and protective door trim with Mugen branding, which can also be found on the rim of the two-spoke steering wheel. Other accessories include the hydrophobic mirrors and the window visors.

Under the skin, Mugen is offering Performance Dampers developed in collaboration with Yamaha, which are said to improve handling and reduce vibrations. Note that the Super-One has a more aggressive chassis setup compared to the N-One e: kei car, featuring a lowered suspension and wider tracks.

Unfortunately, the zero-emission powertrain is left untouched. The Super-One sticks with a single electric motor producing 94 hp (70 kW / 95 PS) in Boost Mode. It is not a headline-grabber, though Honda tries to add some theatre with an Active Sound Control system that pipes in simulated gearshifts and engine noise through the speakers.

Mugen has yet to put a price on any of these upgrades, as they remain under development. A market launch in Japan is scheduled for late May 2026.

Beyond Japan, the Super-One is headed to the UK, Europe, Australia, New Zealand, and parts of Asia, which raises the prospect of a one-make series. It would suit the car rather well.

The trail of breadcrumbs pointing to the return of a proper Subaru STI has been an entertaining one to follow. Shortly after the company put its new racing hatchback through testing, a set of patent drawings surfaced online, fueling more speculation about a potential production version.

The patents, filed at the Japan Patent Office, depict a Subaru hatchback with a wide body kit, WRX-sourced headlights, a new grille, and prominent aero components. It looks nearly identical to the Performance-B STI Concept from the 2025 Japan Mobility Show.

A closer look reveals only minor differences, namely the absence of extra vents on either side of the signature hood scoop and the lack of tailpipes at the rear. The latter likely relates to the patent application itself, much like the blank wheels and simplified lighting details.

Concept Design Captured In Patents

Japan Platform for Patent Information

As reported by Top Gear Philippines, which spotted the filing on the Japan Platform for Patent Information, the documents were submitted on September 29, 2025, one month before the show car’s debut on October 30. The timing, combined with the near-perfect visual match, strongly suggest these drawings depict the Subaru Performance-B STI Concept rather than a rumored 2027 production model.

A quick search of the same database shows that similar patents for the Subaru Performance-E STI Concept were filed on the very same day. They replicate the fully electric fastback’s design without any changes. This is standard practice, as automakers routinely secure design protection for both concepts cars and future production models ahead of their public debut to prevent copyright issues.

What About The Rumors?

While these patents likely exist for legal reasons, the timing of their discovery is what has enthusiasts paying attention. Subaru’s HiPerfX2 hatchback, essentially the racing counterpart to the Performance-B STI Concept, is set to compete in Japan’s Super Taikyu series, where it will double as a rolling development lab.

The race car pulls together an assortment of WRX STI sedan components, wrapped in a widebody hatchback silhouette that appears to draw from the Impreza. Under the hood sits a motorsport-tuned version of the turbocharged 2.4-liter boxer engine, producing 359 hp (268 kW / 364 PS), paired with a six-speed manual gearbox and an all-wheel-drive system.

Talk of a 2027 return for the WRX STI hatchback starts to make more sense when you look at the gaps forming in Subaru’s current lineup. The company has confirmed it will stop taking orders for the WRX sedan in Japan, along with the Levorg and Layback wagons, leaving some notable space to fill.

Another telling move is the removal of the STI Sport grade from the WRX range, which could be less about trimming options and more about clearing the stage for something more exciting with the STI badge.

Whether this all points to a routine model year reshuffle or a deeper generational reset, one that finally brings the STI badge back to a hot hatch, is still an open question.
