That being said, the turbo V8 has been a much bigger issue. The N63 (up to 2013-ish?) was their first “hot-vee” design and had a long list of issues. They had a bulletin to revamp a bunch of stuff called the “Customer Care Package” - dual issue of excessive heat causing oil leaks/consumption + eating batteries. They’ve come out with a few updates - I had N63TU in my 2016 550 and it was trouble free for 3.5 years. |
‘Fil: had you continued to own that v8 the 4th and 5th years might have been brutal, from what I can see from my neighbor’s experience.
So the new N63 successor engine —this also have a hot-vee design but somehow they’ve addressed this?
Why would you want a red-hot turbo impeller near your cylinder heads? Other than packaging.
Doesn’t this seem bad?
