Commuter Cars Corporation and the Tango
The Tango--unique in many ways--has the solution for some of the major problems
we have with automobiles today. Traffic has overcome the current freeway system.
There are too many 4-passenger cars using an entire lane to transport a single
person. There is also too much pollution from gasoline vehicles.
Artist's drawing Solution: Reduce traffic and pollution with the Tango, a car
that fits its use! This tandem two-seater can get you safely and comfortably to
work and back without wasted space or fuel. The Tango--being 6" narrower than
many motorcycles--takes less than half the space of the average car on the
freeway, thereby doubling the capacity of existing freeway lanes. The Tango can
fit in a future 6 foot lane easier than a truck fits in a standard 12 foot lane.
To fight pollution it is available as an electric zero-emission vehicle.
Parking too is a major problem for most commuters. Finding space to park in
congested cities is difficult and time-consuming. Add in the cost of parking
garages and lots or the extra hassle of moving your car and plugging the meter
every hour or two, and people will jump to an alternative when it presents
That alternative is the Tango. Size does matter. As many as four Tangos can fit
in one parallel parking space. Many parking locations also have spaces that only
motorcycles and Tangos can fit in.
Some other long-standing concerns on the show-room floor are safety,
performance, and handling.
Because safety is such a concern for small cars in particular, we have designed
the Tango around a roll cage that meets or exceeds both SCCA and NHRA
regulations. These are racing organizations that specify cage design to protect
the occupants of cars crashing at over 200 mph. In addition, the extremely high
strength-to-surface area ratio of a steel roll cage allows superb visibility
from within the Tango. Rollover too is a great danger for many vehicles. The
Tango, being so narrow, would look to the layman's eye to be unstable. But in
fact, the Tango has stability that exceeds that of most sport cars.

buried in asphalt. As far as performance goes, the Tango is no slouch. Since
electric cars--especially small ones--are generally thought to be slow and weak
performers we set out to blow some minds by designing the Tango to accelerate
through the standing 1/4 mile in 12 seconds at over 120 mph and travel from 0 to
60 mph in 4 seconds.
And as for handling, who would think a car this narrow could compete? All the
people we beat at the autocross!
Getting back to the more typical drive to work, consumers may be interested in
the vehicle's range. Although the Tango can be built with a fuel cell or
internal combustion engine, conventional lead-acid batteries work well for most
commuters. Its 80-mile range is nearly 4 times the distance the average commuter
travels per day. With high-tech batteries, range could exceed 150 miles per
To minimize any day-time inconvenience, the Tango can charge to 80% in just 10
minutes from a 200 amp charging station. This gives approximately 50 additional
miles of range per quick-charge. Typically one would just plug in each night to
a dryer outlet and get a complete charge in less than 3 hours and be ready for
work the next morning.
