Cadillac has been doing something that brands at GM just haven't done in decades. It's building its own engine. And to show it off, it'll have a special logo.

The logo, first uncovered by GM Authority, shows "two stylized wings comprised of six elongated geometric shapes" forming a V in the middle. The trademark filing has also been reserved for use on engines for automobiles, SUVs, and trucks. 

So it's a pretty good bet that this new logo for engines will apply to Cadillac's new "blacking" engine. Which all sounds very exciting indeed.

Cadillac's V8 displaces 4.2 liters and has double overhead cams and two turbochargers for power. According to Cadillac, its good for (at least) 550 hp and 626 lb-ft of torque in the CT6-V and will be paired to a 10-speed automatic transmission.

The engines will be hand built by one of six people certified to make the engines and should appear in V-Sport products (though there's been some indecision on that score).

The engine may also find its way into the Escalade, the CT5-V, and maybe even GM's mid-engine supercar, though all of the above are unconfirmed.

All of the above would look rad with the logo somewhere on their body, though, so we're excited to see the "Blackwing" badged cars when they hit the streets. Just don't confuse it with another dark wing.
