Last month, Toyota launched the iQ city car, to much fanfare amongst the green-machine crowd. Within days, speculation began on a sporty two-seater roadster based on the same small platform. Naturally, the first thing we noticed was its resemblance to the 1965 Toyota Sports 800, itself based on a lesser commuter car, the Publica. If built, the yet-unnamed iQ-based convertible could be powered by a 1.0 or 1.3-liter gasoline or diesel engine. Sadly, unlike its predecessors, both this roadster and the iQ are front wheel drive. Expect to see a prototype at the 2009 Tokyo Motor Show.
