Details of the A-Class E-Cell are expected to be announced in mid-September ahead of its debut at the Paris Motor Show. Straubel told the times that the pack would have a capacity of about 40 kilowatt-hours and contain approximately 4,000 18650 lithium-ion cells. That should be sufficient for about 124 miles of electric driving range. Since the current-generation A-Class is not certified for the U.S. market, the electric variant is unlikely to make it here until the next-generation model arrives.
