Hello, i have been looking at the IQ for the past couple days, there isnt just one site out there that gives you all the information you need, but i was luckey enough to find tid bits and a article in a magazine. The IQ is a so called four seater, the passenger seat sits further forward then the driver to allow more leg room to the back passenger, as for behind the driver seat, there is enough room for a child seat, or a very small friend. You have the choice of filling the car with people, or stuff, not both. the back seats fold down for added space, but with no extra cargo space behind the back seats leaves little room for "crumple" in the case of a rear end collision, I read they just added an extra air bag to make the blow softer for those in the back seat. It has a total of 9 airbags throughout the car, but lacks the Tridion Cell, keep in mind the Tridion is what makes the small Fortwo car able to with stand the impact from larger vehicles. Safety plays a big role in bringing this car to the US, with out a Tridion rip off of some sort i think this will be very difficult. the enguine is also located in the front of the IQ as well as it being front wheel drive, it will come with a 3 or 4 cylinder, depends on the customers preferance.
