The extra power over BMW's own V8 applications (the
similarly -
powerful M760Li instead uses a V12) comes as a
result of airflow optimisation, a wide - bore intake system and uprated pistons and spark plugs, while an air / water / air intercooler keeps intake temperatures low.
That's quite an impressive
result — the Xperia Z5 came out with a multi-core score of 4,015, so the Premium is
similarly powerful.
