If you haven’t heard of Steve Hamilton, he’s amassed a collection of incredible super and hypercars that total to 30 billion dollars. Instead of hiding them away to impress other rich people and preserve the paint by keeping them in a controlled climate storage building so they’ll never see the light of day, he drives them.

He will bring cars to community events, take them to events to let children experience them, generate money for fundraisers, use them for educational purposes, or just to make fun videos.

In the most recent video he posted to his YouTube channel (@TheHamiltonCollection), he decided to use three of his cars to raise money for a local charity. Using a Hennessey Venom F5 Revolution, Bugatti Chiron, or Koenigsegg Regera, strangers could pay $5 for a ride in one.

Here’s why those hypercars are a big deal

The Hennessey Venom F5 Revolution has a twin-turbo “Fury” 6.6-liter V8 that churns up a jaw-dropping 1,817 horsepower. It has a top speed of over 300 mph, and it can go from zero to 60 in 2.6 seconds. It can drive a quarter of a mile in less than 10 seconds. It’s insanely fast, and it’s all from a gas-powered engine.

The Koenigsegg Regera is a hybrid “megacar,” with three electric motors mated to a twin-turbo 5.0-liter V8. It makes over 1,100 horsepower, and it was a limited production model—making it pretty rare.

A Bugatti Chiron is, well, a Bugatti. So it has four turbos bolted onto an 8.8-liter W16 engine (that means it has 16 cylinders, in case you didn’t know), helping it put over 1,500 horses to work. It has the fastest zero to 60 of the bunch at 2.3 seconds.

And, given those stats, all three cars cost millions of dollars.

The customers had the best reactions

When one man walked up to the Regera, the car with the hybridized 5.0-liter V8, his brain went to the same place everyone else’s likely went: a Ford Mustang.

When he was presented with a “hypercar,” he said, “No, that’s a Mustang.” Of course, when Steven drove him around at speed, he took back what he said.

Naturally, some tried to film the entire ride, others stared into oblivion, but most shrieked with joy the entire ride.
