One reason why Diesel powered engines will be faster at Puebla:
- low atmosferic pressure (and lower oxygen level). For standard family cars it's irrelevant, for race cars, 0,001 seconds is the difference between pole and the rest, it's more like having extra weight penalties.
Diesel engines in the Seats, are turbocharged, otherwise they would be sitting ducks in the middle of the track. With all my respect, diesel engines without turbo are hopeless.
This means the air is forced with high pressure in the cylinders, so at the Puebla circuit (2000 m. altitude), they will have an advantage over the aspirated, gasoline engines (the more air is forced in, the more powerful the explosion - the gasoline engines will be limited to current atmosferic pressure).

Again, with all my respect, I can't see the diesel Seats dominating.
There's three possible solutions (in my view):
- all the competitors will switch to Diesel powered engines;
- removing the turbo from Diesel, the gasoline engines are aspirated so there will be some "balance" (no chance, as a Diesel engine is desperately slow, without turbocharger is as fast as a tractor in the field);
- adding turbo for the Otto engines (again not the slightest chance... all the diesel fan will commit suicide). With turbo added, those gas. engines will reach almost or over 400 hp. There will be no such thing as balance.
