What are Hot Wheels Mainlines?

Mainline

Mainline Hot Wheels are the most common and widely produced Hot Wheels cars. They're the foundation of the brand and what most people think of when they hear "Hot Wheels." 

250 different castings are released in the mainline cases from A to Q. 15 lettered case assortments each year now for a while. There are no I or O cases. Those letters are too easy to confuse with numbers 1 and 0.

Key Characteristics:

  • Quantity: Hot Wheels releases around 250 new Mainline models each year, divided into different series like HW City, HW Flames, Factory Fresh, HW Screen Time, etc.
  • Packaging: They come in the standard, familiar blister packs you see in most stores. U.S. gets long blisters, Europe gets mainlines in short blisters.
  • Wheels: Mainline cars typically have plastic wheels.
  • Price: They are the most affordable and easiest to find, usually costing just a few dollars.
  • Hunt: Most Mainline models are not rare. However, the series includes Treasure Hunts (TH) and Super Treasure Hunts (STH), which are much harder to find and highly sought after by collectors.

Super Treasure Hunt (STH) 

Upgraded version of a regular Mainline car. You can find them mixed in with regular cars on the pegs, making them one of the most exciting and sought-after finds.

Key Characteristics:

  • Rarity: They are produced in very small numbers, with a reported average of one STH for every 10 to 15 cases of mainline cars.
  • Upgrades: An STH is a specific Mainline model with three key upgrades:
    1. Spectraflame Paint: A special, glossy metallic finish that is noticeably different from the regular version.
    2. Real Riders: They have rubber tires, just like Premium cars.
    3. "TH" Logo: A small "TH" logo is hidden somewhere on the car's body. The card will also have a subtle golden flame logo behind the car.
  • Hunt: The thrill of the hunt is the main appeal, as you have to search through a large number of regular cars to find one.

Treasure Hunt (TH) 

A Treasure Hunt, or T-Hunt, is a rare, special version of a regular Mainline car. You can find them mixed in with standard cars on the pegs, making them a common but still exciting find for collectors.

Key Characteristics:

  • Rarity: They are less rare than Super Treasure Hunts, with an approximate distribution of one T-Hunt per mainline case.
  • Visuals: A T-Hunt is a specific Mainline model with key visual identifiers:
    • Circular Flame Logo: A subtle, silver circular flame logo is found on the blister card, behind the car.
    • "TH" Logo: A small "TH" logo is hidden somewhere on the car's body.
    • Regular Features: Unlike an STH, a regular T-Hunt will have plastic wheels and standard paint, not Real Riders or Spectraflame paint.
  • Hunt: The thrill of the hunt is a main appeal, as you have to search through a large number of regular cars to find one. They are a perfect entry point for new collectors and a rewarding find for experienced ones.
