The present invention generally relates to a vehicle system which may include a primary clutch operably coupled with a primary inertia, and a torsional spring operably coupled with the primary inertia and also operably coupled to a transmission input shaft. The transmission input shaft may be operably coupled to a secondary clutch which may be constructed and arranged to engage a secondary inertia. The secondary inertia may be used to deliver a dual mass fly wheel effect and the secondary clutch may be constructed and arranged to be opened during shifting events.
