Claas 600 (euro) --> 770 (585 hp max, Mercedes V8 engine (T3))

Claas 590 (580 euro) --> 760 (530 hp max, Mercedes V8 engine (T3))

Claas 580 (570 euro) --> 750 (466 hp max, Cat C13 engine (T3))

Claas 570 (570C euro I guess) --> (431 hp max, Cat C13 engine (T3))

The 770 will have hydropneumatic suspension on the tracks.  Not sure about the others.  They all use the same cab as the 494 Jaguars and Tucano combines.  

*all hp figures come from European brochures, might be different in NA.

600 series will be walker combines, all powered by a Cat C13 (670) or C9 engine (others).  There will probably be some changes within the next 15 months to switch the range to iT4 (and maybe a 780 model for Europe)
