Okay kiddo, let me explain what Aussie Invader 5R is. It's a really cool and fast car that was made in Australia by a man named Rosco McGlashan. He wanted to make a car that was the fastest in the world, so he built the Aussie Invader 5R.
Now, this car is different than most cars you see on the road because it's powered by a really big jet engine! That means it goes super fast, faster than most people can even imagine.
Rosco and his team have been testing the Aussie Invader 5R for a long time to make sure it's safe and can go really fast without breaking. They want to break the world land speed record which means they want to go faster than any other car ever has before!
It's really amazing what people can build, isn't it? The Aussie Invader 5R shows that with hard work, people can make incredible things.
