2010 Lexus IS: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2010 Lexus IS is the arrival of the IS C, a power-folding hardtop convertible offered as the IS 250C and IS 350C. The sedans largely carry over, but they gain useful standard audio upgrades.
About the 2010 Lexus IS
2nd-generation IS sedan (2006-2013), late-cycle tech-update year; 2010 also launches the first-year IS C power-folding hardtop convertible on the same basic platform.
Lexus positioned the 2010 IS as its compact luxury sport-car family: a smaller Lexus with rear-drive proportions, strong V6 power, an upscale cabin, and more comfort and quietness than many harder-edged rivals. It was aimed at shoppers who liked sport-sedan style but still wanted everyday ease and polished road manners. For 2010 that identity broadened, because the new IS C brought the same premium feel to a hardtop convertible.
The IS 250 is the style-focused entry, with a 204-hp V6, leather-trimmed cabin, power front seats, and dual-zone climate control. The quicker IS 350 uses a 306-hp V6 and adds paddle shifters and larger brakes. Both versions appear in the new IS C convertible body style for 2010.
