Proof of Tango's Motor Torque

For many years I've been saying that the Tango has over 1,000 ft lbs of motor torque—500 ft-lbs each. In a recent drag strip event, we proved that the Tango has over 2,500 ft-lbs of torque at the motors—over 5 times the torque of a Viper V-10 engine at peak output. This is proven by the fact that the Tango weighs 3,500 lbs with the driver, distributed 43%-57% front to rear, and a 75" wheelbase. Therefore, it requires 9,500 ft-lbs of torque at the rear wheels to lift the front wheels off of the ground, as demonstrated in the video below. The drive ratio is 3.86:1 from motors to rear axles. It took a very sticky track to accomplish this with street tires. It was prepped with a goo that was stickier than the floor in a 7-11 next to the Slurpee machine—hard to keep your shoes on.
