The battery pack for the Tango is only about 7.5-9 kWh at typical EV rates. On that, it gets 60-80 miles range to 100% discharge.
The car uses high power components because power does not add much expense. It could use a low power Curtis Controller, a single 9" motor, and flooded batteries and have a more modest 50 horsepower or so, but it would only shave about $5k off of the production cost. At low volume, this car is going to be $80-100k. At that price, 50 horsepower will not garner sales, but 400 horsepower will. Small cost penalty to generate big hype and perhaps some sales.
In mass production, this would be a $20,000 car.
