The Toyota mid-engined coupe prototype is heading into Super Taikyu’s October 24–25, 2026 Okayama round with a substantially revised body. Reporting published on October 23 describes a coupe-style redesign of the Toyota GR Yaris M Concept, with Friday practice already under way in Japan. This is a new development stage, not the concept’s first Super Taikyu appearance.
What changed on the Toyota mid-engined coupe?
According to Car Watch’s October 23 report from Okayama, the prototype has received changes to its body structure, chassis geometry and aerodynamics. The revised silhouette is the immediate headline, but the reported work extends beyond exterior panels.
However, a coupe-shaped development car does not establish the design of a future showroom model. The available information supports a substantial racing-prototype redesign, not a production-car reveal.
That distinction also matters when describing its debut. Toyota previously identified Okayama in 2025 as the M Concept’s racing debut. Consequently, this weekend’s story is the revised car’s Okayama outing, rather than Toyota entering the concept in Super Taikyu for the first time.
When will Toyota’s mid-engine prototype race at Okayama?
The official round runs on October 24–25, 2026, at Okayama International Circuit. Friday, October 23, is practice activity and should not be confused with the published race-round dates.
The official Super Taikyu Round 6 schedule and entry information lists Saturday qualifying and Sunday racing. The weekend has two three-hour races; the ST-Q group is scheduled for the morning race.

However, ticket options and broadcast arrangements are not established by the information checked for this report. Consult the event’s official information before making travel or viewing plans.
What engine does the GR Yaris M Concept use?
Toyota’s official M Concept background describes a midship four-wheel-drive layout using the G20E engine. Both the engine and transmission sit behind the driver.
That establishes the project’s mechanical starting point. However, it is not a complete specification sheet for the revised October 2026 car.
No confirmed power output, acceleration figure or maximum speed for this updated Toyota G20E prototype appears in the sources checked. Accordingly, figures associated with other development stages should not be presented as this car’s specification.
For drivers, the interesting questions concern the whole package: how the revised geometry, body and aerodynamics work together over a stint. Those answers require more than a new silhouette or one quick lap.

What lap times did the Toyota prototype set at Okayama practice?
Car Watch reports Friday practice laps of 1:38.003 and 1:37.231. It also cites 1:38.698 as the best lap from the 2025 Okayama ST-Q winner.
The reported 1:37.231 lap is numerically quicker than that historical reference. However, the figures do not establish a controlled, like-for-like performance gain.
Track conditions, tyres, fuel load and the purpose of each run can change the picture. Moreover, these are reported practice figures, not official results from Sunday’s race or a confirmed lap record.
For a clearer framework, our guide to lap times, drivers and record categories explains why the category and circumstances matter. Here, the three-hour race will provide a different test from a single practice lap.
Is Toyota’s mid-engine prototype a new MR2?
Toyota has not confirmed that this revised prototype previews a production MR2 in the sources checked. Nor do those sources establish a Celica connection, a road-car launch date or final production styling.
Instead, the confirmed identity remains the No. 28 GR YARIS M concept. Its Super Taikyu ST-Q entry and coupe-style redesign are newsworthy without attaching an unannounced production badge.
For now, separate three things: the entered race car, its reported development changes and speculation about a future road car. Only the first two have supporting detail in this report.
How can drivers use telemetry at their own track days?
For drivers following the development story, recording their own circuit sessions offers a practical connection. TripRank is an iOS driving and performance telemetry companion that records drives with GPS route capture. Recording works offline and continues in the background.
Each trip has a Smoothness Score. Pro adds Apple Watch heart-rate analytics, aggregate Stats charts and data export. These features do not establish equivalence with Toyota’s prototype testing.
Before recording, work through a first track-day preparation checklist. Keep acceleration and limit-handling tests on closed circuits or authorised private venues.
For the season-ending race weekend, our Fuji Speedway Super Taikyu finale 2026 report covers the confirmed dates, four-hour format and ticket listings.
Separately, ROOKIE Racing has confirmed the front-engined GR GT3 concept’s Motegi competition debut for November 7–8, 2026.
Frequently asked questions
Is this the GR Yaris M Concept’s first Super Taikyu appearance?
No. Toyota identified Okayama in 2025 as the concept’s racing debut. The October 2026 news concerns a substantially revised, coupe-style version.
When is the prototype scheduled to race?
The ST-Q group’s race is scheduled for October 25, 2026, from 08:30 to 11:30 JST at Okayama International Circuit.
Which team and class is the prototype entered with?
The official entry lists No. 28 GR YARIS M concept with GR Team ORC Field in the ST-Q class.
Has Toyota confirmed power figures or an MR2 production link?
No confirmed output figures for the updated prototype or production MR2 connection appear in the sources checked for this report.
Bottom line
Toyota’s revised prototype brings a coupe-style body and reported chassis and aerodynamic changes to Okayama. However, the confirmed story remains a Super Taikyu development programme, not a production-car announcement.
