In the distant past, 24 hour races were always a crap shoot because of attrition. The last few years we have not had that much of it because the original Daytona Prototypes were pretty stout machines. This year it's hard to predict the outcome because the quality of the field goes so deep. This could be the most competitive field of prototypes we have seen since the mid 80s Group C days.
This year is going to be impossible to predict simply because we have so many new teams and combinations. There are also quality winning efforts like the United Autosports car, which would be a contender even without Alonso. You also can't count out the Jackie Chan car, something the Porsche LMP1 team can tell you about. JD Miller now has some capital to work with through Gainsco, and after last year's performances have to be considered solid contenders. The CORE car also looks really, really strong.
Notice I didn't even mention the four Cadillacs, two Nissans, two Mazdas and two Penske Acuras. We have a reasonably complete prototype field even without them. Most people probably believe the winners will come from this list of factory cars, but I am not so sure. Remember that the Gibson V8 is about as reliable as a concrete block, and that will definitely work to the privateer's advantage.
I don't have an entry list in front of me, but I don't believe we have any junk entries. Probably every prototype that lines up will have a chance to win. For some it might take a bit of luck, but at least they have a chance, and hopefully that alone will keep all these cars and teams in the game long term, and hopefully pull in some new teams as well.
So, I don't have a clue who will win. Even if there was a solid favorite it all depends on who hits the set up and gets the breaks. When your throw in weather, slower traffic and parts falling off the cars, or even outright blowing up, there's no way to even make a reasonable prediction. This is what endurance racing is supposed to be like.
Personally I am pulling for any of the smaller P2 teams. When the privateers win, the sport prospers. The flip side is that no one would mind seeing Helio win, Mazda certainly deserves success, and an Alonso win wouldn't hurt the series profile either.
If you also consider that WEC is looking like 25-30 P2 entries and about the same in ELMS, pretty clearly the P2 platform makes the first viable world platform we have ever seen. All the FIA has to do is allow the DPI and P2 cars to go head to head for overall wins and sportscar racing could very well reach a height we have never seen before. Here's one prediction I can fearlessly make: This will be yet another lost opportunity for sportscar racing, and probably the best opportunity we have seen yet.
Still, we are probably going to have the best Rolex we have had in a long, long time.
