For enhanced safety, the front and rear seat shoulder belts of the Lexus IS Series have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Genesis G70 doesn’t offer pretensioners for the rear seat belts.

The IS Series’ optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The G70 doesn’t offer pre-crash pretensioners.

Both the IS Series and the G70 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive, blind spot warning systems, rear parking sensors and rear cross-path warning.

From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that Lexus vehicles are more reliable than Genesis vehicles. Consumer Reports ranks Lexus first in reliability. Genesis is ranked fifth.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The IS Series has a standard brake assist system to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The G70 doesn’t offer a brake assist feature.

The IS Series stops shorter than the G70:

Unlike the driver-only memory system in the G70 3.3T/Elite/2.0T Manual/Prestige/Sport, the IS Series offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

If the windows are left open on the IS Series the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Lexus service department.) The driver of the G70 can only operate the windows from inside the vehicle, with the ignition on.

A power rear sunshade is optional in the IS Series to help block heat and glare for the rear passengers. The G70 doesn’t offer a rear sunshade.

The IS Series will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the IS Series will retain 44.01% to 47.7% of its original price after five years, while the G70 only retains 41.05% to 41.79%.
