Looks like Mazda redesigned the rotors for lighter weight.
They look to me like two piece aluminum diecastings
with a larger rotor bearing and/or phaseing gear.
That would make sense for 280 HP NA at 9000 RPM. To
run that fast both the gear needs to be improved  and
the rotor weight needs to be reduced.

Looks like we are going to need new PSRU's with 3:1
gear ratios.

I'd say more like a 3.3:1 PSRU.  Maximum torque is 23.0 kg-m at 8,000
rpm.  8,000 / 3.3 = 2424 prop rpm.  I wonder how much the engine weighs
now, since presumably Mazda tried to minimize the car's weight for fuel
efficiency's sake.

I also think the "suicide" doors are way kewl.

Those "suicide" doors are all the rage on pickup trucks
and Saturns these days.
