2021 Honda Insight: What's New, Specs & Features
Last updated August 4, 2026
The most important change for the 2021 Honda Insight is the addition of blind-spot warning and rear cross-traffic alert on EX and Touring trims. Otherwise, this is a quiet carryover year with the same hybrid system, trim lineup, cabin layout, and infotainment hardware.
About the 2021 Honda Insight
3rd generation Insight sedan (2019-2022), third model year with no redesign or major refresh.
Honda presents the Insight as a sleek hybrid sedan that delivers standout fuel economy without looking or feeling like an oddball economy car. The emphasis is on elegant styling, a quieter and more upscale cabin, standard safety tech, and a responsive two-motor hybrid system. For most buyers, the Insight is the choice for getting hybrid efficiency in a conventional compact-sedan shape that feels familiar, comfortable, and easy to live with every day.
The LX is the straightforward efficiency-focused trim, pairing a 151-hp hybrid system with automatic emergency braking, adaptive cruise control, and lane keeping assist. EX adds an 8-inch touchscreen, Apple CarPlay, Android Auto, remote start, and the new side-and-rear traffic alerts. Touring is the upscale version, with heated leather-trimmed seats, a moonroof, built-in navigation, and premium audio.
