The Tango currently weighs about 3,100 lbs (trying to get it down), but 2,000 lbs of that are under the floor in the form of batteries, drivetrain, etc. The carbon fiber body only weighs about 25 lbs so it's very bottom-heavy; the batteries sit 4" off the ground and the center of mass is about 13" off the ground. The car is built around an FIA-approved chrome-moly cage and stainless steel chassis and battery box. The door bars are pinned into the rest of the cage.
It seats 2 in tandem, up to 6' 8" each in the newer cars with the passenger straddling the driver seat with out-stretched legs. Both custom Sparco seats have 4-point aircraft pilot harnesses with inertia reels.
For driver comforts, it has a very powerful air conditioner, 400 W Alpine sound system with rear subwoofer, GPS navigation, backup camera, and back-lit MoTeC.
The motor controller has a peak output of 600 kW (805 hp) and can instantly and easily produce over 1,000 ft-lbs of torque. There's one motor driving each rear wheel directly through a 3.5:1 helical gear box on each side.
Let me know if you have any questions.
