Perhaps the coolest part of the Mazda Ryuga concept is its wild, four-passenger interior, accessed by gullwing doors and rendered in white-and-gray leather, polished aluminum, and translucent plastic. The steering wheel of the Mazda Ryuga concept is more of a steering “u”, which may not work real well in reality but sure looks cool. The instruments sprout of the from the dash like big, chrome flowers with both digital and analog readouts.
