Additional Features1. It has a fully usable bed with payload capacity of around 1000 lbs.
2. It can be driven at highway speeds if necessary with a top speed of around 75 mph and a 0 – 60 mph time of around 12 seconds.
3. Driving at moderate speeds (45 mph) it has a range of 80 – 100 miles.
4. It holds 3 passengers.
5. If one drives less than around 10 - 15 miles per day, then there is no need to plug in and charge up the batteries. The sun will provide all of your energy needs.
6. If one drives more than 15 miles per day, then the additional energy costs roughly 3 cents per mile or about 5 miles per Kilowatt-hr.
7. Very low maintenance. Just check battery water level once a month and transmission fluid as usual.
The Solar Black Bear - Performance Highlights

From June 3 to November 3, 1999, the SSB traveled a total of 2446 miles on $75.60 worth of electricity (based on the utility @ $.14/KW, 414.7KWh). Assuming the price of gasoline to be $1.40 per gallon, a gas-powered car would have to get about 45.3 miles per gallon to compare, or operate at a cost of 3.1 cents per mile of travel.

From June to November 2000, 2001 and 2002 the SBB traveled an average of 50-80 miles per week using only energy gained directly from the sun (about 10-15 miles of free driving per day). It cost literally nothing to drive and produced virtually no air pollution for a period of six months each year.
