Famed custom vehicle designer Robert Q. Riley has worked on everything from bikes to kit cars to hovercraft to submarines. Now's he's drawing up plans for a high-performance, diesel-electric hybrid. A spec image (pictured) features a drawn-to-scale victim of Auric Goldfinger, though it's doubtful the figure in any way represents Riley's target market. Do-it-yourselfers can watch for the blueprints, coming soon.
