The 2014 Rolex 24 at Daytona: What we learned, what we saw

Two days after the flag dropped on the 2014 Rolex 24 at Daytona, people are still trying to figure out what it might portend for the rest of the season. In 24 hours, two minutes and 24 seconds, 695 laps were completed by the car that crossed the line first. During that time, 67 cars began the race, 18 of them retired. There was that accident, and a red flag. There were supposedly slower classes beating supposedly faster classes. There were 16 caution periods, including that yellow flag. And then there was The Decision. And Then The Uproar. And then The Reversal.
There was also some pretty good racing, so let's have one last look at the weekend. Oh, and there was that 1964 Ferrari 250 GTO Series II...
If you want to skip the reading bits and go to the photos, there's a high-res gallery of 158 images above and a couple more below. Enjoy.

Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.

'Latest production version' of Porsche 918 shown off on Twitter

Porsche posted a picture of what it is calling "the latest production version" of the 2015 Porsche 918 Spyder on Twitter. It looks like the gasoline-hybrid supercar is being driven sportively on some California back roads during Monterey Speed Week.
Whatever updates were made to this version aren't visual (except for the paint), as the one Chris Harris drove last spring and another seen hot-weather testing in Nevada both had production bodies. We presume the changes are relatively minor and more than skin deep - perhaps brake calibration, suspension tuning or tweaks to the powertrain - but Porsche didn't release any more information.
The 918 Spyder is Porsche's latest supercar, which will compete with the LaFerrari and the McLaren P1 hybrid supercars. The Porsche may be the underdog of the group when considering horsepower, acceleration, top speed and price, but the 887-horsepower brute has the most advanced hybrid drivetrain of the three.
