This situation in the World Touring Car Championship illustrates perfectly why a two-tier championsip is unworkable, and why fans would hate it.

SEAT are comfortably leading the championship with their turbo-diesel Leons, the rest of the field using petrol engines. One of the ways the FIA can "equalise" the cars is by restricting their turbo pressure, which is what they've done for Pau.

Now suddenly SEAT, leading the championship remember, can only qualify 15th.

You've got this rediculous situation where the FIA have clearly hampered the diesels far too much... or have they? Maybe the SEATs weren't that brilliant in the first place and only lead the championship becuase they formerly had too much dispensation. Who knows?

By tampering with the regulations in this way the FIA have created a false picture where nobody bar a handful of engineers really knows the true performance of the cars relative to each other. How is the public expected to understand - or care about - that?

SEAT for their part say this is "as a result of the lack of clarity in the technical regulations and the constant rule changes introduced by the FIA in this championship, hindering participants from fighting at the top level on an equal basis".

The full story is on Autosport, it makes pretty sad reading. We certainly don't want this in F1.
