The system is powered by an innovative, liquid nitrogen Dearman engine, which replaces the standard diesel engine. Since then the Dearman engine has been re-designed and it is already proving to be 30% lighter, 30% smaller, and 30% more efficient than its predecessor. Dearman liquid air engine, Gen 2 design.

A team from McMaster University in Canada has published a comprehensive review of recent progress in low-temperature combustion (LTC), alternative fuels (AF), over-expansion Atkinson cycle, and waste heat recovery (WHR) techniques as applied to hybrid-specific engines. Modern Atkinson engines are mostly realized by VVT technology.
