Page 1 of 1 At the 2002 New York Motorshow Saturn launched two cars for the small-car segment, the ION Sedan and the ION Quad Coupe. The Quad Coupe is so-called because of its dual rear-access doors (RADs). The dual RADs represent an industry first, resulting in the creation of a new category of vehicle and a new, more functional small car.
Built on GM's Delta architecture, the five-passenger sedan and four-passenger quad coupe continue Saturn's traditional spaceframe construction. The new architecture allows the ION models to be substantially bigger than their predecessors - approximately 2 inches taller and 6 inches longer - providing a more significant command of the road. In addition, a wider track (approximately 2 inches front and rear) and longer wheelbase delivers a more substantial presence. Page 1 of 1
