- The Toyota IQ, one of the shortest vehicle in the car market, could not prevail in any country. Positioned as a competitor of the Smart Fortwo, but with three seats instead of two, the Japanese model was proposed at a price (13 500 to 17 500 Euros) probably too high to allow it to compete efficiently with  the Smart (10 000 to 15,000 Euros). The IQ was designed to address the small urban chic car clientele, but the model was probably considered too expensive .

- For a price lower than the IQ, Toyota offers the Aygo (9500 to 12 500 Euros). For a price similar to the IQ, Toyota sells the Yaris (13 200-19 500 euros), with more roominess. The Audi A1 which is also a chic supermini  is not much more expensive (17 000-25 000 Euros) and offers much greater roominess and a more rewarding, image ,  as well as  the Mini (16 000-30 000 Euros ).

- While the carmaker had set a target  of 100,000 sales per year (annual sales level of the Smart Fortwo), the Toyota IQ has never overpassed 60 000 vehicles per year and quickly fell down to less than 20,000 vehicles per year.
