This is a Hot Wheels car called Prototype H-24.
This one got me excited for a second, I thought it was the Porsche LeMans car (same color scheme), but then I realized it was a non-existent car. Oh, well. I couldn't help but buy it anyways. I has a nice little design. It reminds me of a speed racer car, like from the new movie coming out soon.
Here's the Porsche LeMans.
