While sitting down with BMW M CEO Frank van Meel at the Kyalami Grand Prix Circuit in South Africa last week, CarBuzz asked the big boss about a number of M products, ranging from the XM and M2 to the 3.0 CSL Homage that we've seen but officially know quite little about.

While van Meel remained tight-lipped in response to our questions, he left us with this: "The only thing I can say is it's going to be a very special car." It has largely been reported that the 3.0 CSL will be based on the BMW M4 CSL, but van Meel assured us that "the car will look like nothing else" in the BMW stable.

So what's the deal? Why won't BMW divulge any information whatsoever about the car when it was van Meel himself who originally broke the news of the newcomer via his personal Instagram account?

As it turns out, the only reason he did so was that BMW needed to test the car on the track and figured rather it breaks the news than have everyone find out later. "We needed to complete the car on the track. So we knew [...] everyone would see us on the Nurburgring Nordschleife, so that's why I said okay, then we might as well say 'there's something coming,' but we don't say anything more about that car."

At this stage, it's a game of shadows and rumors. The only details we know for sure are those that are pasted all over the prototype's custom wrap.

The "I Like It Rare" sticker alludes to the rumored 50-strong production run, each of which is rumored to carry a price tag in excess of $750,000. That's because the 3.0 CSL Homage is expected to be a highly specialized coachbuilt model from M.

The 3.0 CSL will have a six-speed manual transmission and is expected to deliver nearly 600 horsepower. This will be sent exclusively to the rear wheels, as indicated by the "Drift Happens" sticker on the camo wrap.

Like the M4 CSL, there will be no rear seats, while the front occupants will be cosseted in carbon fiber buckets. Strangely, despite the car seeming so track-focused, it will not be sold with a roll cage as standard, suggesting it will be fully road legal - although reports suggest it won't be made available to American buyers. Not officially, anyway.

With a rumored reveal next month, we might not have to wait long to find out more. Maybe BMW M knows how to build a real halo car after all. In our sit down with van Meel, he admitted the XM SUV is more for appearances than performance, so perhaps the new 3.0 CSL might be able to restore some of our faith in the brand.
