A powertrain system including an internal combustion engine rotatably coupled to a continuously variable transmission (CVT) is described. A method for controlling the CVT includes determining minimum and maximum CVT input speeds in response to an accelerator pedal position, and monitoring vehicle speed and a CVT input speed. A target CVT input acceleration rate is determined based upon the vehicle speed, and a desired speed ratio is determined that is responsive to the target CVT input acceleration rate. The CVT is controlled based upon the desired speed ratio.

A bumper beam for an automobile is disclosed, which has a first set of surfaces and a second set of surfaces. The first set of surfaces is inclined at a pre-defined angle with respect to a pre-defined plane. A plurality of slots is provided on the second set of surfaces of the bumper beam, which facilitates the bumper beam to crush during an impact.

A method and apparatus for absorbing energy during a frontal collision of a vehicle, through the use of a front frame structure having main frame rails that include several deformable and non-deformable sections which are connected by selectively crushable junctures that are configured to predispose one or more of the junctures and sections to pivot selectively outward, rearward and upward, in a predetermined manner, during the collision. The front frame structure also includes an engine cradle, attached below the main frame rails, and having a pair of side rails that include forward and rear crushable junctures joined by non-deformable intermediate sections, with the crushable junctures of the main frame rails and engine cradle side rails being configured to predispose the intermediate sections of the engine cradle side rails to move downward and rearward during the collision.
