The illustrator's over at Winding Road have been having fun with a possible future RX-9 based on previous concepts such as the Mazda Nagare. Their guesstimation picks up some of the Nagare aft of the A-pillar, with a modernization of lines from the current generation RX-8 and last generation RX-7 in the rear. As for under the hood, guesses range from a modified Renesis to something as out-of-character as a V8. But before you rotorheads get up in arms, remember this is all just educated dart throwing.
