Along with Haldex AWD, several Volvo design features were incorporated into the structure of the Five Hundred, including a modified version of Side Impact Protection System (SIPS) from Volvo, channeling impact forces around the passenger compartment; the front frame rails were redesigned to better absorb impact forces [REF].
The Ford Five Hundred/Mercury Montego were powered by a single engine, shared with the Ford Taurus: a 203 hp 3.0L Duratec V6, paired with a 6-speed Aisin automatic transmission (for front-wheel drive versions) or a ZF CVT (for AWD).
