Holy crap balls that's cool.
What's with the shark fin/tiny snorkles on the nose?
Although the Roar Before the Rolex—IMSA’s preseason warmup for its premier series—was mandatory for all the teams expecting to contest the Rolex 24 at Daytona, the clear star attraction of the weekend was the pair of Corvette C8.Rs making their public, at-speed debut.
We were fortunate enough to beat the crowds to the garages and snap a few photos of the cars in their uncovered states before the blankets and tarps came out to hide proprietary setup tweaks from other teams and the public. We even managed to snap a quick photo of the flat-plane V8 before the Chevy crews hid all the interesting bits on the Pratt & Miller-built racers.
While teams are always suspected of holding back a little performance at this preseason test, if we believe the results, the C8.Rs should be competitive right out of the box. The C8.R posted the class’ third-fastest time of the weekend, barely a tenth of a second off the class-leading Ferrari and Porsche machines. That’s solid performance for a rollout, and should bode well for a competitive Rolex 24 at Daytona, and a competitive season for the Corvette Racing team.

Yep - Cool car, like the production version. Hope there's minimal teething problems in the big debut.
Snorkels are pitot tubes that measure speed through air velocity.

I have been wondering that. What is the advantage of having an air velocity reading over other sources of speed?
I'd imagine it is to compare with all the other data being collected. Knowing how fast the car is going over the ground but also how fast it is going through the air is probably very important for them as they make setup decisions and changes. I do wonder if they are just there for testing purposes or if they will remain on the car in competition.
You know your car is badass when it has pitot tubes! 
The C7Rs had the pitot, too, as do the Acura NSX GT3s. I asked about them at the VIR last fall and they said they use the data to measure the downforce they're generating.

Eric Orr
Anything airflow related is best measure at a relative airspeed rather than a relative groundspeed. Things like downforce and brake cooling and air intake velocity will change dramatically based on whether you're driving into a 20 mph headwind or driving away from a 20 mph tailwind.
Any specs on the engine?
The similarities between the C8R and my Fiesta ST are striking. It has 4 wheels...I have 4 wheels! It uses a steering wheel...I steer with a wheel! It has brakes to stop...I have brakes to stop! While the fine details vary a bit ($10K carbon-ceramic disks vs $20 steel) the basics are essentially the same.

5.5L, DOHC, flat plane v8. 500hp/480ft-lbs in (restricted) race trim. Sounds different, but not bad:
