Tula is driven by an overriding passion to increase efficiency and improve the environment. With more than 340 patents issued or pending for multiple technologies, and a combined 450 years of engineering behind those patents, we’re focused primarily on applications for passenger automobiles, commercial vehicles for on and off road and electric vehicles of any size. Our approach to improving efficiency sets us apart. We come at it with demonstrated software solutions, and we deliver proven results with more than one million vehicles on the road using our technologies to decrease greenhouse gas emissions and increase fuel savings. But we’re not stopping there. We’re working to reduce or eliminate the use of rare earth elements in electric vehicles through improved electric motor efficiency and exploring efficiency in other means of mobility, too, including robotics, e-aviation and industrial machinery. Tula drives efficiency.
