The new Smart electric homologous autonomy in cycle NEDC than the previous version. However the cycle EPA homologous 18 kilometres unless they are due to the introduction of a factor of degradation of the battery.
This year, Smart has been placed on the market, the new ForTwo ED and the ForFour ED, the electric version of alternative four-doors. Both were filed in April and the first units have been delivered this summer.
Share mechanical features and only differences in the autonomies approved and certified according to the cycle NEDC: 160 kilometres for the ForTwo ED, and 155 for the ForTwo Cabrio and the ForFour. To achieve it incorporates a battery manufactured by ACCUMOTIVE, a subsidiary of Daimler, 17.6 kWh formed by 96 cells.
Autonomy according to the european approval NEDC
The autonomy to be certified according to the cycle standard european the new new Smart ED are 160 km for the version Fortwo and 155 km for the versions Cabrio and Forfour, higher than in the previous model.
According to has informed us Smart Spain the autonomy has not been increased in a greater extent, for two main reasons. In the first place to be an urban vehicle, the autonomy is suitable for use in city. On the other hand to increase the autonomy implies to increase the price of the battery , and hence increasing the product when it would not be necessary for the utilization profile of these models.
Autonomy according to the approval of the american EPA
The results provided by the type approval according to the cycle american EPA surprised because in it we can see that it gets 58 miles of range (93 miles ) off the 69 miles (111 kilometers) which offered the previous version. That is to say lose 18 kilometers of autonomy.
again, we have been in contact with Smart Spain to know the reason of this apparent loss of autonomy that is not due to a lower efficiency of the battery or the car but to a change introduced in the cycle. This reduction in the autonomy certified is due to the introduction in 2017 in the certification EPA a factor theory which takes into account the progressive loss of capacity of the battery. This factor has been set at a -16% to a life cycle of 5 years. Smart tells us that they expect the customers to get a greater autonomy that the certified.
The input Autonomy approved for the Smart ED first appears in Electric Mobility.
