What next for the DeltaWing?

I don’t see any basis in it becoming a spec chassis unless Nissan did it as a completely separate spec-series off their own back.
What about replacing the Oreca FLM09 as the Le Mans Challenge car, which is a) three years out of date and b) effectively an LMP2 car, running in a highy-competitive LMP2 class?19th June 2012, 10:25 at 10:25 am #203824
I don’t know anything about that class, but wikipedia says that it is ‘intended as part of a ladder system for young and upcoming drivers into the world of endurance racing while also serving as a value engineered entry for drivers and teams into Le Mans Prototypes due to limitations on manufacturers and suppliers.’ I’m not sure that the Delta Wing is any of that- too unusual to prepare young drivers for LMP1 and 2 cars properly, and too specialist to be cheap. Why use a completely irrelevant car in a series that is meant to be highly relevant?19th June 2012, 10:30 at 10:30 am #203825
World Series by Nissan featuring Deltawing?19th June 2012, 10:34 at 10:34 am #203826
Nissan and Renault have a close partnership, don’t they? Or am I mixing up manufacturers?19th June 2012, 10:37 at 10:37 am #203827
Yeah you are right, I forgot about that, it’s just coincidence I used Renault’s race series with the Nissan name.19th June 2012, 12:52 at 12:52 pm #203828
It could happen, but I don’t see why they should.
It will hardly prepare young drivers to take on LMP2 and LMP1 cars, and I don’t see it being anything like as fast as an LMP2 style car with similar specs.
To me it seems like its different, for the sake of being different.19th June 2012, 17:19 at 5:19 pm #203829
Here’s a great, thought-provoking piece about the plans for the Delta Wing design.
The Way It Is / New Technology in Racing (Gordon Kirby)
Interesting words from Marino Franchitti about how well its aerodynamics worked in traffic, and Gordon Kirby raises an important question about hybrids and safety – that could so easily have become a matter of life and death. Definitely one for the round-up @willwood !19th June 2012, 18:23 at 6:23 pm #203830
I would be interested to see how the drag on a similarly non-winged, but full-width car would look, particularly if the centre was kept very low and sleek. I wonder if the narrow section actually helps a huge amount or if it just makes it quirky enough to appear more interesting. I think a full-width but equally low drag, low-powered and light-weight car would be a better move for future thought. It wouldn’t be weird for the sake of it, but would otherwise hold true to Delta Wing’s efficeincy intentions. It could make a fun little series- fast, light, little prototype-like cars.19th June 2012, 18:47 at 6:47 pm #203831

@matt90 Like Radicals? Or is that an ignorant thing to say? I’m not too savvy on LMP technology.19th June 2012, 19:47 at 7:47 pm #203832
Sort of, but not necessarily to a spec, and with more of a focus on ground effects rather than wings- so more specifically low-drag than Radicals, and possibly with a wheelbase and track closer to LMP cars.19th June 2012, 21:25 at 9:25 pm #203833
I can only agree with that. Low drag and high dependency on floor created downforce could provide for a great racing series, but there is no need the shape it like the DW.
The point in shaping the car like the DW is that it has a very small frontal area, where a normally configured car will be larger, because its wider, but again the wider car will have a larger floor on which it will be able to create downforce, and you can easily make it as light as the DW so I think if you apply the DW concept to a normal car you will get a much faster car, but probably a slightly higher fuel consumption.1st August 2012, 14:39 at 2:39 pm #203834
Why not an experimental class in the WEC1st August 2012, 16:04 at 4:04 pm #203835
I don’t think that’s quite correct. For a start, the narrow front track means they can run extremely narrow front tyres, which significantly reduces drag. Tyre wear on the DeltaWing was also extremely low because of the low weight/drag setup; they reckoned they could have done up to 10 stints on a single set. The deltawing shape meant that the floor was the most efficient shape for a venturi, meaning you didn’t get the loss of efficiency you got from a rectangular wheelbase.
Basically, everything which was great about the DeltaWing came specifically from the shape. It certainly wasn’t a gimmick, and they literally wouldn’t have been able to create something with similar efficiency with a traditional wheelbase.1st August 2012, 17:56 at 5:56 pm #203836
True there were gains from the weird shape, I didn’t know that the triangular shape was better for a venturi, so yeah thats surely an advantage from the shape. But as I said, the low weight and low drag principle could easily be achieved with a conventional layout.
Maybe the DW setup is slightly more efficient, but you need to be fast and efficient to win. I don’t think the DW has proven to be a better setup for endurance racing then the conventional setup.
While the DW concept is very interesting, it is so far just a different approach to things. Whether it is better, or at least competitive is yet to be proven. Therefore I think all the talk about racing categories for it is very premature.1st August 2012, 17:57 at 5:57 pm #203837
