February 4, 2009 Aptera have displayed two prototypes at the Technology, Entertainment, Design (TED) conference held annually at Long Beach California and have revealed more specifications for the 2009 production 2e that we reported on just days ago. The big news is finally some specs for the powertrain. The 1500lb (680kg) curb weight Aptera 2e will have a 60 ft/lb (81 Nm) electric motor driving the front wheels through a 10:1 single speed gearbox with power provided at 336 volts by a 10 – 13 kw/hr Lithium iron phosphate battery pack.
Still no details on battery supplier, motor type or power output at this stage. Without knowing the motor type (the Aptera does have regeneration, so the motor is either a BLDC or AC Induction type) or the torque curve we can only calculate an educated guess based on the torque figure and gearbox ratio information provided. The 2e electric motor power output could be in the range of 100 hp (75kw) at over 13,000 rpm. While that might not sound like much, with such a lightweight chassis and super low 0.15 Cd drag coefficient much less power is required to equal the performance of a heavy conventional steel vehicle.
