The GR Corolla’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Mazda 3 does not have an oil pressure gauge.
The power windows standard on both the GR Corolla and the Mazda 3 have locks to prevent small children from operating them. When the lock on the GR Corolla is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Mazda 3 prevents the driver from operating the other windows just as it does the other passengers.
If the windows are left open on the GR Corolla the driver can close all of them 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 Toyota service department.) The driver of the Mazda 3 can only close the windows from inside the vehicle, with the ignition on.
The GR Corolla’s standard Smart Key System allows you to unlock the doors from either front door handle, open the trunk, and start the engine, all without removing the key from pocket or purse. Push Button Start standard on the Mazda 3 only offers hands-free access for the ignition, none to unlock the car.
The GR Corolla’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mazda only offers heated mirrors on the Mazda 3 Select Sport/Preferred/Carbon/Premium.
The GR Corolla has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the Mazda 3 Select Sport/Preferred/Carbon/Premium.
Compared to traditional radio, the Toyota GR Corolla’s standard SiriusXM satellite radio provides an unmatched listening experience. Its extensive coverage guarantees consistent, crystal-clear reception across the continental U.S., and access to over 100 channels dedicated to a multitude of genres, including music, news, sports, talk shows, and comedy, many with only limited commercial breaks. Satellite radio is only offered on the Mazda 3 Premium.
To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Toyota GR Corolla has a standard wireless phone charging system (Qi) in the center console. Only the Mazda 3 Carbon/Premium offers wireless charging.
