“It's a beautiful car inside out. It's easy to use the interior controls. It grips the road and maneuvers well. A premium car with all the premium features. It's a little more sluggish / clunky than I was hoping power wise, but the car boogies when you need it to!”
2021 Lexus IS: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for 2021 is a major mid-cycle overhaul, with an extensive redesign and chassis retune on the existing platform. It is a substantial update, but not an all-new generation.
About the 2021 Lexus IS
3rd generation (2014-2025), major 2021 redesign/refresh on the existing platform
Lexus positions the IS as its compact sport sedan for drivers who want sharp styling, a rear-drive feel, and Lexus comfort in a smaller package. The core appeal is not outright track intensity; it is the mix of responsive handling, quiet cabin quality, upscale materials, and everyday usability, with all-wheel drive available for buyers in colder climates. In this class, the IS stands out more for design, build quality, and smooth day-to-day livability than for raw power numbers.
The IS 300 is the core model, balancing the sharper new look with everyday comfort, synthetic leather upholstery, and power front seats. The IS 350 F SPORT is the more aggressive version, pairing a 311-hp V6 with 19-inch wheels, unique exterior details, and heated and ventilated sport seats. Both receive an 8-inch touchscreen and the updated driver-assist suite.
What changed, by category
Styling
The IS receives a wider, more aggressive body with new lighting and a stronger visual stance. F SPORT is limited to the IS 350, so the IS 300 F SPORT and non-F SPORT IS 350 leave the lineup. The IS 350 F SPORT also gets standard 19-inch wheels and a rear spoiler, while the power moonroof changes from standard to optional across the lineup.
Structural
The body structure is stiffer, while the suspension and steering are retuned to improve handling and responsiveness.
Tech
An 8-inch touchscreen becomes standard, along with Apple CarPlay and Android Auto.
Safety
The newer Lexus Safety System+ 2.5 driver-assist suite arrives. Blind-spot monitoring with rear cross-traffic alert also becomes standard.
