Abstract: A computer having a processor and memory that stores instructions executable by the processor, wherein the computer is programmed to: receive adaptive transmission clutch data from a plurality of first vehicles, the data from each first vehicle including a modified shifting profile; determine, using the received data, an updated initial shifting profile; and provide the updated initial profile to a plurality of second vehicles.

Abstract: An exhaust gas aftertreatment system having a housing and a plurality of separate diesel particulate filter bricks disposed in the housing. A first one of such bricks is disposed upstream of a second one of the bricks. The second one of the bricks has channels with closed downstream ends and open upstream ends and channels with closed upstream ends and open downstream ends and the upstream brick has channels with closed downstream ends and open upstream ends and bypass channels with open upstream ends and open downstream ends.

Abstract: An air induction arrangement 7 for a variable displacement engine is provided. The air induction arrangement 7 includes first and second plenums 22, 24 fluidly connected to respective first and second throttles 26, 28. The first and second throttles 26, 28 are connected to respective first and second inlets 44, 60. In partial operation, the air induction arrangement 7 induces air into the first plenum 22. In higher power demand operation, the air induction arrangement 7 additionally induces air through the second plenum 24. There is a reduction of the cancellation of acoustic output between the first and second inlets 44, 60 so that an acoustic output of the engine 14 operating with only a first group of cylinders 16 is similar to the acoustic output of the engine when the engine is operating with both groups of cylinders 16, 20.
