The design on this one isn't too bad, I think it's your best so far.
Just somethings that could be improved:
→ The tires don''t have any radial blur on them.
→ The smoke doesn't look realistic. (Could be motion blurred a bit)
→ There are parts just in front of each wheel that have been smudged.
→ The front far wheel is missing.
→ The spoiler isn't positioned the best it could be, move it to the right a bit.
→ There's no one driving it.
→ It's going towards a barrier (maybe because no-one is driving it?

).
Keep it up.
