TESTA 3.0 is REV's current main project, an improvement upon the original TESTA. TESTA 3.0 has been given a new black fiberglass body and several other significant improvements. We are planning to compete with TESTA 3.0 in the Shell Eco-Marathon in 2016.
Tachyon competed in a different category at the Shell Eco-Marathon than the other two cars, the Urban Concept category. Tachyon ran a 48 VDC system, with two brushless motors. It had on an Arduino Galileo with custom code, and a custom-designed motor controller. Tachyon was disassembled in the fall of 2015.
TESTA was REVs second car. There were two TESTA iterations. The first was a partially solar-powered vehicle, and the second focuses mainly on efficiency. Both ran on a 36 VDC system with one brushless motor. Both had a custom aluminum chassis and fiberglass body. TESTA 1 placed 3rd in Solar Category at the 2012 Shell Eco-Marathon, while TESTA 2 placed 12th at the 2013 Shell Eco-Marathon.
Photon was REVs first car. It ran on a 36 VDC system, with a brushless motor and controller. The body and chassis were altered from the Electrathon kit. It placed 18th in Battery Electric Charge category at the 2013 Shell Eco-Marathon, with a usage of 62.88 miles per kilowatt-hour.
