A powertrain has an engine with a crankshaft. The powertrain includes a planetary gear set having a first, a second, and a third member. The first member is connected for common rotation with an input member. A first clutch is selectively engageable to operatively connect the crankshaft with the input member. A second clutch is selectively engageable to ground the input member with a stationary member. An electric motor/generator has a rotor operatively connected for common rotation with the second member. An output member is provided, with a set of intermeshing gears configured to transfer torque from the third member to the output member. A first gear pair and a second gear pair are operable by engagement of a first synchronizer and a second synchronizer, respectively, to provide two different fixed ratios between the input member and the output member.

A system for absorbing energy in a vehicle includes a pair of laterally spaced upper and lower side rails which extend along a longitudinal axis. The lower side rails are disposed below the upper side rails. An upper member extends transverse to the longitudinal axis and interconnects the upper side rails. A lower member extends transverse to the longitudinal axis and interconnects the lower side rails. The upper and lower members are each disposed to transmit energy from the upper and lower members through the respective upper and lower side rails. The upper and lower members are configured to simultaneously deform upon impact of the vehicle with an object and transfer a force generated from impacting the object to the upper and lower side rails, respectively.
