The Lexus IS Series may be more efficient, handle and accelerate better because it weighs about 600 to 1000 pounds less than the Genesis G80.

The IS Series is 1 foot shorter than the G80, making the IS Series easier to handle, maneuver and park in tight spaces.

The IS Series 300 RWD offers available computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The G80 doesn’t offer active noise cancellation.

As tested by Car and Driver while cruising at 70 MPH, the interior of the IS 350 F Sport is quieter than the G80 5.0 (65 vs. 70 dB).

Unlike the driver-only memory system in the G80, 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 G80 can only operate the windows from inside the vehicle, with the ignition on.

Consumer Reports rated the IS Series’ headlight performance “Fair,” a higher rating than the G80’s headlights, which were rated “Poor.”

Optional air-conditioned seats in the IS Series keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The G80 only offers an air-conditioned driver’s seat.

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 G80 only retains 36.48% to 41.02%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Lexus IS Series will be $1411 to $15373 less than for the Genesis G80.
