The 2008, and as far as we know the 2009, USA 451 smart fortwos do NOT have the Micro Hybrid Drive (MHD) feature.
They are delivered with a seperate electric starter moitor and a 90 amp alternator, both seperate components.
The MHD variant uses a special Motor/Alternator that is capable of stopping the motor and starting the car faster then a typical starter motor and pinion / ring gear set up
