Initially, I wasn’t too taken by this EV, and its been around a while, but after seeing it handle and accelerate, it looks like a lot of fun. Instinctively, you think it will tip over around curves, but you have to keep in mind that there are several heavy batteries on the floor, keeping its center of gravity extremely low. It also has a reinforced NASCAR rollcage; so it’s safer than it looks. Commuter Cars Corporation has lofty hopes of getting this car under $20,000; I hope they can do it. Listen to the guy’s reaction to the acceleration at 2:50.
I mean George Clooney’s got one, what else do I have to say?
The Tango is a plug-in EV produced by Commuter Cars Corporation. It may look like a small economy car, but the Tango is neither cheap nor slow. This in-line two-seater will rocket from 0-60 in 4 seconds and can reach a top speed of 135 mph. It meets or exceeds the performance specs of electric supercars like the Tesla Roadster and the Venturi Fetish. It’s price is comparable too, at $108,000. Just watch how a Google exec weaves through highway traffic as Danny from DannysContentment.net holds on for dear life in the backseat:
Also, I was intrigued by Danny’s other Tango video with Google’s solar powered charging station in their parking lot. Hats off to them; what an amazing glimpse into the future. If we could have these at more workplaces, it certainly would make a greener world. Maybe a tax write off as incentive for more companies to put these up would make some execs feel greener:

Seating: Tandem Sparco custom bucket seats with 4-point aircraft pilot harnesses on attached structures. Passenger straddles the front seat and harness structures which do not interfere with the passenger’s knees.
Storage: Passenger and a few bags of groceries with rear seat installed. Removed, it allows 2 very large suitcases and a large breifcase with the driver’s seat in extended position. (Rear seat with harness structure is removable through rear hatch.) Multiple compartments for smaller items.
Headroom: 39″ driver and passenger.
Trailer Hitch: Accepts standard 1.25″ hitch for towing generator cart for extended range. Front hitch for moving small airplanes.
Note: Projected performance specifications will vary depending on final weight, gearing, tires, and batteries used. Acceleration figures assume racing slicks are used on a drag strip.
Range: 40-60 miles maximum with Lead-Acid batteries
over 150 miles with Li-Ion batteries
Cost per Mile: About 1/2 the cost of a gasoline car for the average commuter. (See note.)
Acceleration: 0 to 60 MPH, about 4 seconds. 1/4 mile time about 12 seconds at a speed of approx. 120 MPH (See note.)
Top Speed: 135 MPH (See note.)
Cost per Mile:
The average round-trip commute in the U.S. is 20 miles according to the 2000 report from the Bureau of Transportation Statistics.
For that average commute of 20 miles and up to 24 miles per charge, the total cost per mile of the Tango is approximately 30% lower than that of a Honda Insight. This includes battery replacement, maintenance, and the cost of electricity at $.05 per kWh (as in the Northwest). The Honda Insight has an EPA rating of 56 mpg city and 57 highway. Please see the Cost-per-Mile Spreadsheet for details. This spreadsheet shows how the Tango compares with other vehicles, both Internal Combustion Engine (ICE)-driven and hybrid. It includes gasoline and recommended dealer maintenance costs for the gasoline cars and electricity, maintenance, and battery replacement costs for the Tango.
In California where electricity rates are nearly $.15 per kWh, the total cost per mile for the Tango becomes roughly equal to that of the Insight. Electricity cost per mile runs from 0.9 cents to 2.6 cents as cost per kWh goes from 5 cents to 15 cents.
0 to 60 MPH, about 4 seconds. 1/4 mile time about 12 seconds at a speed of approximately 120 MPH. These figures are based on comparisons with other cars that hold official records with NEDRA (National Electric Drag Racing Association). Calculations have taken weight, motor torque, controller, voltage, gear ratio, and traction into consideration. They assume that racing slicks are fitted and driven on a drag strip with good traction conditions. For example, the world record held for a dragster used the same controller as the Tango in the Current Eliminator IV, with a quarter mile time of 8.801 seconds at 137.65 MPH. The Tango has the same motors that the Maniac Mazda used to achieve an 11.039 second quarter mile at 111.80 MPH.
135 MPH. This is a limitation based on a practical red-line for the motors of about 8,000 RPM with the standard 3.86:1 gear ratio. Top speed vs. acceleration can be traded off by choosing any of 10 different ratios from 2.92:1 giving a top speed of 172 MPH to 5:1 which would give a top speed of 100 MPH. The 5:1 would give phenomenal acceleration if you could get enough traction.
