During the 1960s SAT made a number of innovations, experiments and extended to new areas. In 1961 the radial type hydraulic motor Sisu Nemo was patented. The main use was powering of trailer axles but Nemo's were installed also in number of other applications. The 1963 introduced K-138 features another innovation of the same period: vertical ejector exhaust pipe that dilutes exhaust gases. At the early 1960s also wide tyres to substitute double wheels were tested; the experiment done together with Nokia did not, however lead to production.
