The Saturn Ion was a compact car sold by the Saturn marque of American automaker General Motors between the 2003 and 2007 model years. It used the GM Delta platform. The Ion replaced the Saturn S-Series in 2003, and was replaced by the new Saturn Astra in 2008. As of 2006, the Ion was the longest compact car sold in North America. Production of the Ion ended on March 27, 2007.
The 2003 Saturn Ion Quad Coupe production car first appeared at the 2002 New York International Auto Show. The 2003 Ion came standard with a 2.2 L 140 hp (104 kW) DOHC Ecotec I4 engine. The Ion's instrument panel was mounted on the top center of the dashboard, rather than behind the steering wheel. The Ion is available in sedan and coupe forms; the coupe featured a set of bi-parting doors; the feature marketed as quad coupe.
A Getrag F23 5-speed manual or an Aisin AF33 5-speed automatic transmission were available. The compact 5-speed automatic had several unique characteristics. The transmission lacked an overdrive, allowing for five forward gears to be packaged in the size of a typical four-speed manual gearbox, both providing close gear ratios for better acceleration and fuel efficiency while eliminating the heat and parasitic loss generated by the additional planetary gearset. The unit was also “fill-for-life”, meaning that it was not intended to be serviced for the life of the vehicle. The 2003 and 2004 Ion Coupes were available with the VTi continuously variable transmission or a Getrag F23 5-speed manual.
Aisin's transmission was generally unpopular among Ion reviewers because of a so-called "shift flare" that was not a defect, but, nevertheless, a disorienting feature of the designed shift pattern that resulted in some drivers becoming alarmed when the transmission downshifted on a downward incline (as the driver released the gas pedal).
For 2004, Saturn also re-calibrated the electric power steering, as well as upgraded interior materials, and offered new sound systems.
In 2005, the Aisin 5-speed automatic transmission was discontinued due to a problematic trait known as shift-flare, which also occurred in other manufacturers' cars using Aisin transmissions, such as Toyota. The VTi CVT used in the quad-coupes between 2003 and 2004 was also discontinued, for reliability reasons. GM's 4-speed 4T45-E replaced both transmissions, becoming the only available automatic transmission option. The 2005 models also received a new steering wheel, the same one used in the 2004 Red Line model. In the middle of the 2005 model year, the seats in the base Ion1 model received upgraded fabrics and a height adjustment feature. "Quiet Steel" multilaminate sound-reduction technology was also introduced in 2005. Cosmetic changes included an upgraded fascia with a larger grille opening and redesigned wheel covers and redesigned alloy wheel offerings. Under the hood, an acoustic engine cover was added to the engine bay to reduce noise emissions.
The 2006 model year saw only minor cosmetic changes. The Level 2 and Level 3 models were offered with GM's new standard radio, featuring MP3 playback.
The 2.2-liter Ecotec engine in the 2007 Saturn Ion was improved over the previous year's model: power output increased from 140 hp (104 kW) to 145 hp (108 kW) at 5600 rpm, and torque output increased from 145 lb·ft (197 Nm) to 150 lb·ft (203 Nm) at 4200 rpm. The new engine was fitted with the ECU from the 2.4-liter engine.
The 2.4-liter Ecotec received a similar upgrade: power increased from 170 hp (127 kW) to 175 hp (130 kW) at 6500 rpm, and torque increased from 162 lb·ft (219 Nm) to 164 lb·ft (222 Nm) at 4800 rpm.
An "Appearance Package" was offered for the 2007 Ion 3 Quad Coupe, including redesigned front and rear bumpers, side moldings, elliptical fog lamps, and a chrome exhaust tip. The Recaro seats in the Red Line version were replaced with black leather-appointed seats, which featured a passenger-sensing system.
Red Line Edition
In production from 2004 through the 2007 Model Year, Saturn produced the Red Line Sport Compact This engine/powertrain combination is also shared with the Chevy Cobalt SS Supercharged Edition, which did not start production until the 2005 model year. The Ion Red Line features most interior features from the standard Ion Coupe, including its rear suicide doors, to allow accessibility to the rear seat.
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 10 mm, 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-tipped 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.
On October 17, 2003 at the Bonneville Salt Flats in Utah, the Saturn Ion Red Line, piloted by the GM Performance Division's "Saturn Land Speed Record Project" set a new land-speed record in the "G/Blown Fuel Altered" Class at 212.684 mph. This exceeded the previous record holder of 183.086 mph that was set in 2001.
Below are the Production Numbers for the Ion Red Line from 2004 to 2007.
