Racing Mini 4WD at 40: The 2026 Anniversary Releases

Racing Mini 4WD turned 40 in 2026, and Tamiya marked it the way it usually marks anniversaries: not with a fanfare, but with a handful of limited kits and parts that appeared in the August release list alongside everything else. If you only read the item numbers you would miss what they are. This guide covers what Tamiya actually released for the 40th — the Zenperor 3 polycarbonate body special, the Dash-1 Emperor back on a Type 3 chassis, and the two commemorative Atomic-Tuned 2 motors — and is honest about which of them changes anything on track and which is a paint job with history attached.

What the anniversary is actually counting

Mini 4WD as a product line is older than 40 years, which is why the anniversary maths can look wrong. Tamiya is counting Racing Mini 4WD specifically — the racing-oriented series that began in 1986, not the earlier Mini 4WD models. Tamiya's own product copy for the anniversary items dates the start to the 1986 release of the Hotshot Jr., a shrunk-down version of the Hotshot R/C buggy and the first Racing Mini 4WD model; CoroCoro's machine catalogue fills in the rest — June 1986, series No.1, item 18001.

There is a wrinkle worth knowing, because it comes up every time someone tries to name "the first one". CoroCoro's machine catalogue — Shogakukan's magazine has been the Mini 4WD record-keeper since the beginning — dates the Hornet Jr., item 18002, to May 1986, a month before the Hotshot Jr. Its entry says plainly that although the Hornet Jr. was the second Racing Mini 4WD in design order, manufacturing circumstances meant it reached shops first. So the series number and the shelf date disagree: No.1 is the first by intent, No.2 is the first by delivery. Both ran the Type-1 chassis — a shaft-driven four-wheel-drive layout built for the new series, sharing the Hotshot's styling rather than any of the R/C car's mechanism. The short history of Mini 4WD covers the decades that followed; this article stays with what Tamiya put in the 2026 catalogue.

Zenperor 3 Polycarbonate Body Special (95703)

This is the centrepiece of the wave and the one with the most substance. It is a tribute to the original Zenperor 3, designed by Yasuyuki Maeda, reissued as a clear polycarbonate body on a VZ chassis moulded in dark blue with pearl-white A parts. Tamiya lists it at 158 x 98 x 47 mm with a 3.5:1 gear ratio, POM 620 plastic bearings, and five-spoke wheels on super-hard small-diameter low-profile tyres with an offset tread.

Two things make it more than a livery. The first is that a polycarbonate body is a genuinely different proposition from the usual moulded plastic one — lighter, and shaped by trimming and heat rather than by the sprue layout, which is why polycarbonate specials tend to end up on serious cars rather than shelves. The second is that the instruction manual carries a commentary piece by Maeda himself. That is unusual enough to be the reason to keep the manual rather than bin it with the sprues, and it is the sort of thing that makes a kit worth more intact later — see the guide to collecting rare and discontinued kits for why completeness matters more than condition in this hobby.

A note on Tamiya's own spec sheet: the English page lists the VZ chassis and, separately, “includes double-shaft motor,” which do not go together. The Japanese page for the same item gives the line simply as “motor included,” with no shaft count — so the double-shaft wording is an English translation slip, and the VZ chassis and the 3.5:1 ratio stand as written.

Dash-1 Emperor on the Type 3 chassis (18025)

The Dash-1 Emperor returns as Racing Mini 4WD series No.25 on a Type 3 chassis — 127 x 86 x 53 mm, a motor in the box, slick tyres, and a choice of 5:1 or 6.4:1 gearing. Tamiya's description leans on the same things it leaned on originally: the slim, deep rear wing, the jutting side pontoons, and plastic thinned in places purely to save weight.

This is a reissue, not a modernisation, and that is the point. Type 3 is a 1980s chassis and it behaves like one — the gear ratios on offer are both slower than the 3.5:1 that current chassis default to, and there is no roller provision remotely like a modern car's. If you are buying it to race a current three-lane or five-lane layout you are choosing a handicap on purpose. If you are buying it because you had one, or because a vintage-class night is a real thing at your local track, it is exactly right. The vintage kit guide covers what running an old chassis genuinely involves.

A separate Dash-1 Emperor Silver Plated Body Set (95712) and a matching Red Spike Tire & Silver Plated Wheel Set (95713) are dated for around 12 September, so the same shape can be built two ways without hunting a second kit.

The 40th anniversary Atomic-Tuned 2 motors (95188 and 95189)

Two commemorative motors shipped in the same August wave: 95188, the single-shaft version for standard chassis, and 95189, the PRO version for the dual-shaft chassis. Both carry a black end bell and a gold-on-black label instead of the usual Atomic-Tuned 2 dressing.

The question everyone asks about limited-edition motors is whether they are actually faster, and here the honest answer is no. Tamiya publishes the same performance figures for these as for the standard Atomic-Tuned 2 — roughly 12,700–14,900 rpm for the single-shaft version and 12,300–14,500 rpm for the PRO. Nothing in the specification says these are a different motor. Buy them because you want the black-and-gold one, or because you were going to buy an Atomic-Tuned 2 anyway and the price is the same; do not buy them expecting a gain. Where Atomic-Tuned 2 actually sits relative to Torque-Tuned and Rev-Tuned is covered properly in the tuned motor comparison. A Black Plated Screw Set (95233) shipped alongside them, which is a cosmetic item and makes no claim to be otherwise.

What to buy, if you are buying one thing

For a racer: the Zenperor 3 special, because a polycarbonate body and a current VZ chassis are both useful regardless of the anniversary sticker, and the tyre and wheel spec is a real race combination rather than a display one. For a collector: also the Zenperor 3, kept sealed or at least kept with its manual, since the designer commentary is the part that cannot be reprinted into a later release. For someone buying out of nostalgia rather than either: the Dash-1 Emperor, with clear eyes about what a Type 3 chassis will and will not do on a modern course.

The wider context for all of this sits in Tamiya's Official Mini 4WD Guide 2026-2027 (item 63809), which carries the anniversary feature alongside the year's Japan Cup circuit and grade-up-part data. It is Japanese-language only, and at 102 pages it is a reference rather than a read.

Frequently asked questions

Is Mini 4WD 40 years old in 2026, or older?

Older. Mini 4WD as a product line began earlier; what turned 40 in 2026 is Racing Mini 4WD, the racing-focused series that started in 1986 with the Hotshot Jr. Tamiya's anniversary products all count from that point.

Which was really the first Racing Mini 4WD, Hotshot Jr. or Hornet Jr.?

Both answers are defensible. Hotshot Jr. is series No.1 and is what Tamiya calls the first. Hornet Jr. is No.2 but reached shops a month earlier, in May 1986, because of manufacturing timing — CoroCoro's own machine catalogue states this explicitly.

Are the 40th anniversary Atomic-Tuned 2 motors faster than the normal ones?

No. Tamiya publishes the same rpm range for the anniversary versions as for the standard Atomic-Tuned 2. The black end bell and gold label are the difference; the motor is not a different specification.

Can I actually race the Dash-1 Emperor Type 3 reissue?

You can, but you would be giving away a lot. Its 5:1 and 6.4:1 gearing are both slower than the 3.5:1 current chassis use, and it has no modern roller provision. It suits a vintage-class night or a display shelf far better than an open three-lane race.
