Dolus eventualis aka Eventualvorsatz, which can indeed be summed up as “willingly hazarding the consequences”. AFAIU in English that’s not a type of intent but recklessness. It certainly is not intent to kill someone, just intent to not give a fuck whether someone dies, there’s a difference there.
Trying to sum up the stuff that distinguishes Totschlag from Mord with “malice” is also rather… vague. The key factor in this case (or at least the aspect that’s easiest to establish) is killing by using means that are a danger to public safety, to wit, a car going 226km/h. Certainly doesn’t fit the dictionary definition of “malice”.
