active rear from evo 4 to evo X
active center from evo 7 to evo X

[Munkvy]

They most definitely have an active centre diff. Google it...

How on earth did I miss this?
I should burn my engineering degree and commit suicide out of shame!

Did you notice that in the third post of the evolution.net link have a link to a pdf which describe the drivetrain. In the most right text box on the upper part say that evo 3 and 4 had a viscous coupling and from evo 5 an active one.

Here’s a link to AYC document about the development.

I have also (February 2008) downloaded an document of the development of the ACD but I couldn’t find it on internet anymore.

Power/Torque:
280 hp (approx) @ 7500rpm
450 Nm (approx) @ 7500rpm

Those figures cannot be right. 450 Nm @ 7500 rpm equals approximately 474 hp. The torque figure quoted must be at a much lower engine speed.
I suspect some technical illiterate in a marketing department has put maximum power, maximum torque & maximum rpm together on the Mitsubishi R5 web page in a way they were not originally specified.

[Mirek]

Yes, that's clear nonsense but since the publically presented power and torque figures are never true I doubt many people on this board bother to read them at all
