The Scion iQ concept vehicle was unveiled in April 2009 at the New York Auto Show. The Scion IQ Concept car 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.
