MUNCLE MIKE'S COLLECTOR GUIDE
Baja Bison T5 — Casting Info & Complete Collector’s Guide
The Baja Bison T5 is an original Hot Wheels electric rally-raid truck design. Its wide windshield, raised stance and rally-style body give the casting a distinct identity; the releases are easiest to tell apart by their color, graphics, wheels and packaging codes.
The casting
Mattel introduced the Baja Bison T5 in the 2023 HW Green Speed series. The card describes it as a T5 electric cross-country rally truck, highlighting a water-cooled battery system, high ground clearance and a large windshield. Sonny Fisher is credited as the casting designer.
Across the series, the recognizable form stays the same while finishes and graphics change. The 2023 pair carries rally and sponsor markings; later releases shift to First Response liveries, a chrome-gold chase finish and multipack editions.

How to identify the releases
Use the toy code together with the body finish and series. The two 2023 Green Speed cars share 143/250 and 7/10, and the two 2024 First Response cars share 058/250 and 6/10, so those printed numbers alone cannot identify the colorway.
JDM25 is the chrome-gold Purple and Gold chase. JKG10 and JTH60 are five-pack codes shared across every vehicle in their respective packs; each Baja Bison is the fifth vehicle. For those two, match the casting and its decoration as well as the number.

Value Research
Start with the individual toy code and finish, then check the series and whether the car came from a single-card mainline, a chase set or a five-pack. The 2023 HKG44 and HKK23 share 143/250; the 2024 HTB61 and HTD29 share 058/250. Their toy codes and finishes are needed to identify the exact version. For JKG10 and JTH60, distinguish the pack code from the individual casting record.
Compare sold examples in like condition: loose with loose, and carded with the same release and similar card and blister condition. For multipacks, record whether you are comparing a loose car, the complete set or an opened pack. This guide does not assign a price range without matched completed-sale evidence.
Collector notes
At close range, compare the wheels and side printing as carefully as the body color. The 2023 blue and green cars are both numbered 143/250, while the two 2024 First Response cars are both 058/250. Their toy codes are the decisive identifiers.
On loose examples, inspect the front corners, roof edges, wheel openings and large windshield for paint rub or scratches. On a multipack example, check that the car is the Baja Bison T5 rather than relying on the JKG10 or JTH60 pack number alone.
Collector FAQs
Who designed the Baja Bison T5?
Sonny Fisher is credited as the designer of the Hot Wheels original casting.
Which releases share a mainline number?
The 2023 HKG44 and HKK23 colorways share 143/250 and HW Green Speed 7/10. The 2024 HTB61 and HTD29 colorways share 058/250 and HW First Response 6/10.
Are JKG10 and JTH60 the Baja Bison T5’s individual toy codes?
Those are the five-pack codes. Identify the Baja Bison by its decoration and casting, and retain the set context; the 2027 Electrorush entry separately lists NN015 as the vehicle SKU.
