The Optima’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Honda only offers heated mirrors on the Accord Sedan EX/EX-L/Touring.

Both the Optima and the Accord Sedan offer available heated front seats. The Optima EX/SX also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Accord Sedan.

The Optima EX/SX’s optional air conditioned front seats cool the driver and front passenger and help take the sting out of hot leather in Summer. The Accord Sedan doesn’t offer air conditioned front seats.

On extremely cold Winter days, the Optima’s optional (except LX) heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Accord Sedan doesn’t offer a heated steering wheel.
