The redesigned for 2021 IS brings a mild update that doesn't stray much from the previous model. It is offered in rear- or all-wheel-drive with a turbocharged four-cylinder engine for rear-wheel-drive. AWD brings a V6 engine. Handling is said to be improved. The interior remains very snug and still suffers from a protrusion into the driver's legroom in AWD versions. The infotainment system still relies on a distracting touchpad but now the screen is touch enabled. There is a complete roster of advanced safety and driver assistance features that come standard, including automatic emergency braking with pedestrian and daytime bicycle detection, blind spot warning, rear cross traffic warning, lane departure warning, and lane keeping assistance. An all-new IS 500 F Sport debuts for 2022, powered by a 472-hp 5.0-liter V8 engine. The ultra-sporty IS also gets a retuned suspension and upgraded brakes, as well as several interior and exterior styling changes. And there's big news for rear-seat passengers: a rear armrest with built-in cupholders is now optional.
