2007 Saturn ION Coupe Wallpaper.........Saturn has an innovative coupe in the ION, with its rear-opening doors and mini-Dent resistant plastic body panels. Although the ION is sleek and attractive on the outside, the interior center dash-mounted gauges are difficult to use when driving. If the standard 145-bhp 2.2L I-4 does not have enough muscle, it can be replaced with the optional 175-bhp 2.4L the ION-3. A supercharged 2.0L I-4 engine with 205-bhp provides extra thrust to the performance-oriented ION Redline, which is only available with a 5-speed manua. Buyers looking for sporty styling and reasonable value of the ION may find a good deal, although the odd interior ergonomics may be a deal breaker.
