Just received this video (click on this link) taken by Michael Woon, of the Tango going through the chicane at Michigan International Speedway during finals. During this run, the Tango achieved both 100 miles and 100 MPG equivalent with approximately 10% state of charge at the end. This, despite rather aggressive driving, but not as tough as the stop and go in the urban and city cycles. And, of course, this time without running the air conditioning.

Thomas Greither, takes a friend up to the end of the road on Mt. Shasta in his Tango. Both are over 6-ft. tall. This photo is at 9,000-ft of elevation. It the first electric car that we know of that's climbed Mt. Shasta. It did this with ease and the round trip only used 35% of the charge. His Tango is now equipped with 1,000 Headway energy cells, 10 in parallel and 100 in series. This gives him 32 kWhrs, which is about 120 miles of 60 mph relatively level freeway driving.A year ago, when he only had lead-acid batteries, I followed him around M... more »

The Tango was never designed to be the most fuel-efficient car in the world. To do that, safety and rollover threshold would be compromised. The fact that the 3,300-pound Tango made it to finals in the Automotive X-Prize competition is quite remarkable.Following is the official data from the efficiency event. Note that although the Tango was less than 1% short of the required MPGe to go to Argonne for the Validation Stage, it needed 104 MPGe, because of the emissions requirement. They use a national grid average to calculate the emissions from ... more »

I'm just returning now from a successful completion of the X-Prize Knockout event. Staying in Bismarck ND tonight, I should be back in Spokane Tomorrow. I'll be taking the Tango back to Finals at Michigan International Speedway (MIS) on July 18 through 30th.During the Shakedown event last month, Consumer Reports captured the Tango in the 0 - 60 acceleration and braking events, but didn't get the the emergency-avoidance (moose test or double lane change, as it's often called), before I had finished it. During Knockout, to the best of my knowledg... more »

We are still contenders in the Automotive X-Prize competition due to no small contribution from other teams and volunteers. We've now completed the first week of the Knockout stage which consisted of economy runs which require 67 MPGe (Miles Per Gallon Equivalent) and a range, in our class, of 67 miles at 60 mph. We completed these easily, of course, however, the urban and city driving cycles brought the Tango down to 86.8 MPGe due to lack of regen which we sacrificed in order to have the extreme torque of two series-wound traction motors. The ... more »

We are trying to raise capital to further the Tango project to drive toward lower cost Tangos. The Pepsi Refresh Project is a way to win a $250k grant which can be used for demos and tooling to reduce cost. We need your votes. All you have to do is to click on this link and vote for our idea. It is only for the month of June.Please Click Here.
