Drivetrain layout with CVT

A drivetrain layout comprising:

• a primary gear reduction operationally engaged to an output of a motor;
• a continuously variable transmission (CVT) including a primary pulley, a secondary pulley and a belt operationally engaged between the primary pulley and the secondary pulley, the primary pulley of the CVT operationally engaged to the primary gear reduction, the primary gear reduction reducing a rotational speed of the output of the motor that is coupled to the primary pulley of the CVT;
• a launch clutch in operational engagement between the motor and the primary pulley of the CVT;
• a range box operationally engaged with the secondary pulley of the CVT, the range box configured to couple torque between the CVT and wheels of a vehicle, further wherein a single engine torque path is provided from the output of the motor through the CVT to the range box;
• and
• a peak torque limiting (PTL) device in operational engagement between the secondary pulley of the CVT and the range box, the PTL device configured to slip to limit torque spikes through the drivetrain layout.

A vehicle comprising:

• a motor to generate engine torque, the motor having an output;
• a drivetrain including,
