Saturn Ion Red Line
The Ion Red Line is an overlooked GM performance car, as the Saturn brand was not marketed as selling high performance vehicles. The Red Line claims a 0-60 mph time of 6.0 seconds, and a 1/4 mile time of 14.6 seconds. GM Performance re-tuned the Spring and bushing rates, and reduced the ride height by about 10mm, and added larger 4-wheel disc brakes. The car was also equipped with 17-inch forged alloy wheels and Dunlop Sport SP9000 215/45 tires, thicker performance sway bars, re-valved shock absorbers, and Recaro racing seats. The larger disc brakes made the Red Line capable of decelerating from 70 mph in 164 ft., what John Phillips of Car and Driver Magazine described as "Porsche territory". Also included was a 2.25 inch exhaust system with a Chrome-tip pipe that allowed for a more aggressive exhaust note from the tailpipe and GM's OnStar System. The Ion Red Line was introduced with a base price of $20,950.
Introduced for the 2005 model year was the optional Competition Package. Included in the Competition Package were 17" Gunmetal Painted Alloy Rims, Ladder Tachometer w/ shift lights, a Limited Slip Differential, and Optional Projector-beam Fog Lamps. In mid-2006, GM released two Engine Kit upgrades for both the Ion Red Line and the Cobalt SS. The Stage 1 Kit retailed for around $500 USD, and included higher-flow fuel injectors and a recalibration to the ECU to increase the Horsepower by 31 hp to 236 hp and 205 lb.-ft. of torque, up from the stock 205 hp and 200 lb.-ft. The Stage 2 Kit retailed for around $750 and opens up the middle of the power curve to more power than the Stage 1 Kit alone. In addition to everything that the Stage 1 Kit comes with, the Stage 2 Kit includes a smaller drive belt and pulley for the supercharger, bringing the engine up to 241 hp and 218 lb.-ft. of torque. GM did release a Stage 1 to Stage 2 Upgrade kit that retailed for $400. This Upgrade Kit is for a Red Line with the Stage 1 kit already installed. This Upgrade Kit adds the Stage 2 elements and increases the horsepower from 236 hp to 241 hp.
