Lupine Racer 2 vs Dog Racer: AR or Super-II?
Lupine Racer 2 and Dog Racer both put a painted animal driver into a real Mini 4WD kit, but this comparison genuinely changes chassis family. Lupine Racer 2 item 18102 is AR; Dog Racer item 18086 is Super-II. Both published packages use 5:1 gears and include motors, so the choice is not a simple “faster gear” decision. It is a choice between an open-top Thunder Shot with a wolf and a Shiba-inu buggy, as well as between two different chassis assembly and maintenance layouts.
Check the item numbers before comparing
Lupine Racer 2 is Racing Mini 4WD Series No.102. Tamiya gives it an open-top Thunder Shot body, a preassembled and painted wolf figure, and metallic stickers. This is the second Lupine release on AR; an earlier Lupine Racer used a different chassis. Dog Racer is Racing Series No.86 with its Shiba-inu driver, white buggy body and character sticker. A product photo featuring a wolf or dog is not enough to establish the chassis generation. Use 18102 and 18086 respectively on the listing and package.
The broader animal racer overview introduces Dog, Cat, Panda 2 and Lupine 2 together. Here the important question is narrower: do you want AR's body and maintenance layout, or a simpler Super-II learning platform? A buyer can enjoy either as a first kit, but the parts and printed chassis diagrams will differ.
What comes with each car?
| Stock feature | Lupine Racer 2, 18102 | Dog Racer, 18086 |
|---|---|---|
| Chassis | Red polycarbonate-ABS AR, black A parts | Light-green Super-II, white fittings |
| Body and driver | Open-top Thunder Shot, painted wolf | White buggy, painted Shiba-inu |
| Wheels and tires | Orange five-spoke, dark-blue large-diameter slicks | White V-spoke, large-diameter narrow arched tires |
| Kit gears and motor | 5:1, motor included | 5:1, motor included |
| Published specification | 155 × 97 × 47 mm in specification block | 150 × 97 × 45 mm |
Both require two AA/R6 cells separately. The tire descriptions differ even though the gear ratio matches: Lupine has slicks, while Dog has arched tires. Those are package facts, not a measured verdict for every circuit. Similarly, the AR versus Super-II name tells you about the platform you will assemble, not which racer must win a local heat.
How the chassis decision changes the build
Super-II keeps the motor at the rear and uses a relatively exposed, familiar single-shaft layout. AR also has a rear motor but uses a more enclosed body-and-underpanel arrangement, with underside parts intended for routine access. Read the correct instructions before opening a gear cover or changing a stay; the covers and attachment points are not interchangeable just because both cars are Mini 4WD. Whichever you choose, first check free wheel movement and secure body mounting with the stock wheels and tires. The AR guide and Super-II guide cover later platform-specific work.
The character body is another practical difference. The wolf sits in an open Thunder Shot cockpit, while the Dog's buggy forms a different space around its figure. When test-fitting rollers and stays, put each body on and check the animal, canopy edge and wheel openings. Do not assume an upgrade that clears one will clear the other. If you are entering a class event, confirm any figure removal or body trimming with the organiser's current rules; the official product pages only describe the stock models.
A note about Lupine's published length
Tamiya's Lupine 2 English page has an internal discrepancy: a short caption near the top says 150 mm, while its specifications block gives 155 mm. Tamiya's AR chassis page also uses 155 mm for the platform. The table above labels the 155 mm figure as the product specification block rather than quietly choosing one number. If exact clearance matters, measure your completed car, especially after adding any stays. Dog's official page consistently lists 150 mm for its stock assembly. This small source conflict is a good reason to build and measure by item number rather than using a generic animal-racer chart.
Which animal racer fits your goal?
Pick Lupine Racer 2 if you want the Thunder Shot body, wolf figure, AR platform and dark-blue slick-tire look. Pick Dog Racer if you prefer the Shiba-inu buggy and want to learn on Super-II. Neither 5:1 kit is presented by Tamiya as a guaranteed faster choice. Visit Lupine Racer 2 (AR) or Dog Racer (Super-II) for the exact stocked product pages.
Frequently asked questions
Is Lupine Racer 2 the same chassis as Dog Racer?
No. Lupine 2 uses AR; Dog uses Super-II.
Are the wolf and dog figures finished?
Tamiya describes both drivers as preassembled and painted. The cars themselves require assembly.
Why do Lupine dimensions differ online?
Tamiya's own Lupine page gives two lengths. Its specifications block says 155 mm, while a caption says 150 mm; measure a finished car when an exact limit matters.
