• "Comfort"￿mode￿on￿the￿F97/F98￿delivers￿a￿distinctly￿comfortable￿ride￿to￿satisfy￿any￿demands
for￿comfort￿on￿the￿part￿of￿BMW￿X3￿M￿or￿BMW￿X4￿M￿customers.￿The￿basic￿damper￿hardness
is￿comfortable￿without￿forfeiting￿safe￿handling￿in￿an￿emergency￿(such￿as￿during￿rapid￿evasive
maneuvers).
• "Sport"￿supports￿a￿demanding￿M￿dynamic￿and￿sporty￿driving￿style￿with￿increased￿basic
damper￿hardness￿and￿sufficient￿remaining￿comfort￿(for￿example￿on￿country￿roads￿or￿bumpy
racetracks￿such￿as￿the￿Nürburgring￿Nordschleife).
• "Sport+"￿on￿the￿F97/F98￿now￿also￿means￿that￿M￿dynamic￿control￿comes￿into￿effect,￿with
the￿basic￿shock￿absorber￿stiffness￿being￿further￿increased￿relative￿to￿"Normal".￿It￿may
