"Typical Porsche 911 install would include 16-28 batteries depending on range, weight, and speed desired. These electric cars have respectable performance, 0-60 can be around 5 seconds.
2000 amp controller with 269 volts, 11" WCE motor in 4th gear at a .98 ratio = 1,200 ft lbs of Torque!
The Electric Porsche drives like a normal Porsche but Electric motors don't stall, the torque is available from the start. Very easy to drive. Generally 4th 5th and reverse are only used. If a direct drive is what you want we can design a special system for you.
Lithium in the new Porsches (99-'08) also offers a close final weight with the gas '08 and with rear trunk to boot. The front trunk is untouched, more overall.
