Hot Wheels we used: boosters, Race Crate and Mega Hauler

Four Hot Wheels sets our boys use: a small booster, a larger powered track, a folding race set and a car hauler. The motors get loud, and the loaded truck can tip.

Quick answer

The small Booster Pack makes sense if your kid already owns track. Ultra Boost is a bigger powered build with pieces we have stacked. Race Crate is the folding race toy; Mega Hauler is for loading cars. I would choose by whether your kid wants to build track, race four cars or load them onto a truck. We used all four, and neither powered set is quiet.

Hot Wheels Race Crate

The Race Crate is awesome for us: the boys still race four cars at once through its loop layout. Mattel includes two cars, so a four-car race needs extras.

Representative Hot Wheels Mega Hauler CKC09 loaded with cars on a wooden floor

Family-used hauler

Hot Wheels Mega Hauler Truck

Our boys still use the Mega Hauler, and loading cars holds their attention. Its six expandable levels make it a carrier rather than another track set.

Fully loaded, ours gets heavy and can topple over. Mattel rates CKC09 ages 3+; keep its small cars away from younger kids. Mattel · CPSC

Before you buy

  • Powered or unpowered: The two boosters need D batteries. Race Crate and Mega Hauler do not.
  • Track building or car carrying: Mega Hauler carries cars; the other three products add boosts or race layouts.
  • Age on the package: Mattel’s service ages span 3+ for Mega Hauler through 6–12 for Ultra Boost.
  • Any product: check current recall information before buying — the kids' product recall tracker lists recent CPSC recalls of children's products.

How I narrowed it down

We put rechargeable batteries in our Booster Pack to avoid buying new ones, although Mattel lists two D alkaline batteries for GBN81. The pictures were staged from verified model photos; they don't show our house or our actual toys. The Hauler pictured has the CKC09 mechanism, but its cab art differs from ours, which has a 50 badge.

  • The exact Mattel models are GBN81, GWT44, GKT87 and CKC09. I used their maker pages for ages, batteries and box contents.
  • The Race Crate instructions list three builds and two included cars. Our four-car loop races use additional cars.
  • I did not time a race, count a full Hauler load or measure battery life. The loud motors and tip-prone full truck are what we noticed at home.

I'm Matt, a dad of two boys. If we've used something at home, the card says personally tested. The rest I read up on. I keep a weekly list of kids' product recalls. How I pick.
