The name iQ, an initialism of the term intelligence quotient, recalls a competitor, the Smart Fortwo. According to Toyota, the i stands for “individuality” “innovation” and “intelligence”, while the Q stands for “quality” and points to the iQ’s “cubic” shape. It was Japanese Car of the Year for 2008.
The design emphasizes low fuel consumption, maneuverability, environmental friendliness, and maximized interior space. Six specific design factors contribute to IQ’s minimal overhangs, forward windscreen location, maximized cabin space and overall compactness. These include a newly developed differential and a centre take-off steering gear, a flat fuel tank and rear-angled shock absorbers, a smaller heater/air conditioning unit and asymmetric dashboard, and a slimmer seat design.
