RE: New Mercedes Engine (6.2L)
It probably has an angled head design, almost definetely not a Hemi however. Hemis have many undesirable characteristics for street vehicles, like carbon build up, inability to meet emission standards etc. You'll notice that even the Chrysler 5.7-6.1 Hemi, really isnt even a Hemi. Its what we call a Semi Hemi. The combustion chamber has a very noticeable flat spot in it to help with the above mentioned issues. The new Hemi is a fantastic engine though, definetely on par with GM's LS smallblocks in design.
