New architecture
Built on GM's all-new 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.
The new, stiffer Delta architecture leads to significant improvements in noise and vibration, as do hydraulic engine mounts, dual balance shafts on the Ecotec powerplant, and enhanced noise dampening throughout the vehicle.
On the inside, the seating position is significantly higher for both front and rear occupants, improving entry and egress and providing a more commanding view of the road. The quad coupe is equipped with "fold-flat" passenger front and rear seats for enhanced functionality to the small-car market. Both models feature significant interior storage, including three bins in the instrument panel, CD storage in the console, and map pockets in both the front and rear doors. In addition, the ION sedan is expected to have the most trunk room in its class - and the quad coupe's dual RADs and fold-flat seats bring so much versatility that even items such as a stepladder, or even a small kayak, can be toted in its interior compartment.
