Powertrain

The powertrain encompasses all the subsystems that generate the drive torque and ultimately transmit it to the road via the tyres. Traditionally, this involves an internal combustion engine via a clutch, manual gearbox, differential, drive shafts and tyres; or, in the case of hybrid or fully electric powertrains, where the electric motor eliminates the need for certain subsystems (clutch, manual gearbox). The following equipment is available for investigating the various powertrain strategies.
