the silhouette appears to be a ferrari 599. though one of my fav looking ferraris, you may run into copyright/licensing issues if you intend this to be an identifier of your brand and corporate identity.
in your signature, the contour is generic and simple enough to be recognizable as a car, but could get murky as anybody who lives near hills or mountains may mistake them for a landscape.
i recommend tweaking the contours you already have to a more definable shape, maybe closer towards that ferrari in the example images you posted.
i have not begun to attack the typography, but it seems to me the ferrari silhouette is your most prominent element of the this stage of your logo. typography can follow if you aim for the silhouette to be more unique to your identity.
i'm sure you have already, but brainstorm a few ideas and keywords of what you want your logo to convey. doesnt have to make sense, random words like potato or canary might make it in the list. right now you are getting it all out on paper so you can narrow the focus of the brand image before diving into design.
