Re: All about Z4 (E89/ E86/ E85) thread
ndeed, but S35is is using N55 with single Turbo...
There are many articles out there that pointed out the N55 engine being use on
the F10, the new E70 and E71. There is no intention at the moment to have it on
the Z platform. The S35is version was out way before the first F10 was commercially
made available. Understand that S35is was launched for those itching for a ZedM.
Unfortunately, that's not going to happen and thus the S35is is really a tuned-up S35i
with an N54 inside. The BMW statement is "N55 will give you same power with the single
scroll turbo but better fuel efficiency and a smoother ride".
Well, the N54 doesn't win engine of the year (for so many consecutive years) for nothing.
I am sure the low end rev performance (though more raw) will give it an edge off the lights.
It may be slightly more jerky, edgy ..but we all bought the roadster not because it is the
quietest and smoothest of the lot right?
