With a crossflow cylinder head, a V-shaped canted valve arrangement and a multi-spherical combustion chamber design, the G-15 was the most technologically advanced Japanese car engine of its day, eclipsing even Nissan's L series engine in their design. The Nissan G engine was not related to the Prince engine; the Nissan version was OHV and slightly smaller displacement.
