About the 2012 Lexus IS

Second-generation IS sedan (2006-2013), first-generation IS C retractable-hardtop convertible (2010-2015), and first-generation IS F performance sedan (2008-2014); 2012 is a late-cycle year just before the all-new 2014 IS sedan redesign.

The 2012 Lexus IS range is Lexus’s compact luxury lineup for buyers who want sharper styling and a more driver-focused feel than the softer ES, but still value Lexus build quality, cabin quietness, and everyday comfort. In sedan, retractable-hardtop convertible, and V8 IS F form, the range covers entry luxury through serious performance. Its main draw is the blend of rear- or all-wheel-drive choices, smooth V6 or V8 power, and a richer-feeling interior than many rivals offered at the time.

The 2012 range spans the comfort-focused IS 250, the stronger IS 350, and two convertibles with retractable hardtops. The IS F is the performance standout, pairing a 5.0-liter V8 with an eight-speed automatic, a limited-slip rear differential, Brembo brakes, and a sport-tuned suspension.
