              3.2.34. "Dynamometer in 2WD operation" means a 2WD dynamometer, or a 4WD dynamometer which only simulates inertia and road load on the powered axle of the test vehicle and where the rotating wheels on the non-powered axle shall have no influence on the measurement results compared to a situation where the wheels on the non-powered axle are not rotating.

              3.2.35. "Dynamometer in 4WD operation" means a 4WD dynamometer which simulates inertia and road load on both axles of the test vehicle.

              3.2.36. "Coasting" means a functionality of either an automatic transmission or a clutch which, when no propulsion or a slow reduction of speed is needed, decouples the engine from the drivetrain automatically and neither a propulsion energy is applied to the wheels nor recuperation energy is taken from the wheels nor friction braking is applied. During application of this function the engine may be idling or switched off.

              3.2.37. "Reference mass" means the vehicle's mass in running order less the uniform mass of the driver of 75 kg and increased by a uniform mass of 100 kg.

              3.3. Pure electric, pure ICE, hybrid electric, fuel cell and alternatively-fuelled vehicles

              3.3.1. "All-Electric Range" (AER) means the total distance travelled by an OVC-HEV from the beginning of the charge-depleting test to the point in time during the test when the combustion engine starts to consume fuel.

              3.3.2. "Pure Electric Range" (PER) means the total distance travelled by a PEV from the beginning of the charge-depleting test until the break-off criterion is reached.

              3.3.3. "Charge-Depleting Actual Range" (RCDA) means the distance travelled in a series of WLTCs in charge-depleting operating condition until the Rechargeable Electric Energy Storage System (REESS) is depleted.

              3.3.4. "Charge-Depleting Cycle Range" (RCDC) means the distance from the beginning of the charge-depleting test to the end of the last cycle prior to the cycle or cycles satisfying the break-off criterion, including the transition cycle where the vehicle may have operated in both depleting and sustaining conditions.

              3.3.5. "Charge-depleting operating condition" means an operating condition in which the energy stored in the REESS may fluctuate but decreases on average while the vehicle is driven until transition to charge-sustaining operation.

              3.3.6. "Charge-sustaining operating condition" means an operating condition in which the energy stored in the REESS may fluctuate but, on average, is maintained at a neutral charging balance level while the vehicle is driven.

              3.3.7. "Utility Factors" are ratios based on driving statistics depending on the range achieved in charge-depleting condition and are used to weigh the charge-depleting and charge-sustaining exhaust emission compounds, CO2 emissions and fuel consumption for OVC-HEVs.

              3.3.8. "Electric machine" (EM) means an energy converter transforming between electrical and mechanical energy.

              3.3.9. "Energy converter"
