Don't think so. The one that won was the first version of the 767B, this is the second, don't think it did all that well.
I would think that Mazda would keep the winning won, and well the others. Just like Nissan has kept the failed, but Tony Southgate designed R390...they gave away the homologated one.
Yes, as mentioned that sound of the Mazda engine is a beast. I wish that they had produced the Furai and continued the Rotary engined Le Mans theme.
