6. Saturn Ion Red Line
From 2004 to 2007, Saturn’s Ion Red Line proved that GM could cultivate performance even in a brand known for economy cars. Its supercharged 2.0-liter Ecotec four-cylinder packed 205 horsepower and 200 lb-ft of torque—similar in output to early Cobalt SS models. The Red Line’s robust five-speed manual transmission and firm sport suspension offered a direct, connected driving feel, allowing 0-60 mph times around 6.5 seconds.
Adding to its credibility, the Ion Red Line came standard with Brembo brakes and an extra-wide front sway bar, which significantly reduced body roll during aggressive cornering. With aggressive side skirts and a rear spoiler, the Ion Red Line announced its performance credentials, proving that inexpensive four-cylinder sedans could still pack a punch.
