The design limits the loss of energy as heat by a variety of technologies; using lube oil as coolant too, no water cooling of the engine block is required, though an oil cooler is needed. It had a 25% fuel efficiency advantage over contemporary designs in the 1980s. Several revolutionary improvements were achieved in this design, such as a new piston design and combustion process.
