The GR Corolla has standard Whiplash Injury Lessening Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Injury Lessening Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Civic Si doesn’t offer a whiplash protection system.

The GR Corolla has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Civic Si doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The GR Corolla has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Civic Si doesn’t offer all-wheel drive.

Both the GR Corolla and the Civic Si have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available rear parking sensors.

Warranty

Toyota pays for scheduled maintenance on the GR Corolla for 1 year and 13000 miles longer than Honda pays for maintenance for the Civic Si (2/25000 vs. 1/12000).

There are over 15 percent more Toyota dealers than there are Honda dealers, which makes it easier should you ever need service under the GR Corolla’s warranty.

Reliability

The battery on the GR Corolla is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the GR Corolla’s battery 20 to 30 degrees cooler, its life is increased by years. The Civic Si’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the statistics that show that Toyota vehicles are more reliable than Honda vehicles. J.D. Power ranks Toyota second in reliability, above the industry average. With 59 more problems per 100 vehicles, Honda is ranked 18th.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Toyota vehicles are more reliable than Honda vehicles. Consumer Reports ranks Toyota second in overall reliability. Honda is ranked fifth.

Engine

The GR Corolla’s 1.6 turbo 3-cylinder produces 100 more horsepower (300 vs. 200) and 103 lbs.-ft. more torque (295 vs. 192) than the Civic Si’s 1.5 turbo 4-cylinder.

As tested in Car and Driver the Toyota GR Corolla is faster than the Honda Civic Si (manual transmissions tested):

	GR Corolla	Civic Si
Zero to 60 MPH	4.4 sec	6.8 sec
Zero to 100 MPH	11.3 sec	16.9 sec
Quarter Mile	13 sec	15.1 sec
Speed in 1/4 Mile	106 MPH	94 MPH
Top Speed	144 MPH	130 MPH

Transmission

The GR Corolla offers an optional automatic transmission, for driver comfort, especially in the city. The Civic Si doesn’t offer an automatic transmission.

The GR Corolla Premium Plus’ launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Civic Si doesn’t offer launch control.

Brakes and Stopping

For better stopping power the GR Corolla’s brake rotors are larger than those on the Civic Si:

	GR Corolla	Civic Si
Front Rotors	14 inches	12.3 inches
Rear Rotors	11.7 inches	11.1 inches

The GR Corolla’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Civic Si are solid, not vented.

The GR Corolla stops shorter than the Civic Si:

	GR Corolla	Civic Si
100 to 0 MPH	301 feet	312 feet	Car and Driver
70 to 0 MPH	151 feet	160 feet	Car and Driver
60 to 0 MPH	108 feet	110 feet	Motor Trend

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the GR Corolla is 2.1 inches wider in the front and .9 inches wider in the rear than on the Civic Si.

The GR Corolla’s front to rear weight distribution is more even (58.4% to 41.6%) than the Civic Si’s (60% to 40%). This gives the GR Corolla more stable handling and braking.

The GR Corolla handles at 1.02 G’s, while the Civic Si pulls only .94 G’s of cornering force in a Car and Driver skidpad test.

The GR Corolla executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the Civic Si (24.9 seconds @ .74 average G’s vs. 26.3 seconds @ .67 average G’s).

For better maneuverability, the GR Corolla’s turning circle is 2 feet tighter than the Civic Si’s (36.1 feet vs. 38.1 feet).

Chassis

The GR Corolla is 10.4 inches shorter than the Civic Si, making the GR Corolla easier to handle, maneuver and park in tight spaces.

Passenger Space

The GR Corolla has .8 inches more front headroom and .5 inches more rear headroom than the Civic Si.

Cargo Capacity

To allow full utilization of available cargo room, the GR Corolla’s hatch uses gas strut supported hinges that don’t intrude into the cargo area. Its intrusive beam hinge reduces the Civic Si’s useful trunk space.

Ergonomics

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 Civic Si does not have an oil pressure gauge.

The GR Corolla Premium Plus has a standard heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Civic Si doesn’t offer a heads-up display.

The power windows standard on both the GR Corolla and the Civic Si 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 Civic Si prevents the driver from operating the other windows just as it does the other passengers.

The GR Corolla’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Civic Si’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the GR Corolla 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 Toyota service department.) The driver of the Civic Si can only close the windows from inside the vehicle, with the ignition on.

To improve rear visibility by keeping the rear window clear, the GR Corolla has a standard rear wiper. The Civic Si doesn’t offer a rear wiper.

The GR Corolla’s optional rear view mirror has an automatic dimming feature. This mirror can be set to automatically darken quickly when headlights shine on it, keeping following vehicles from blinding or distracting the driver. The Civic Si doesn’t offer the luxury of an automatic dimming rear view mirror.

On extremely cold winter days, the GR Corolla Premium’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Civic Si doesn’t offer a heated steering wheel.

The GR Corolla Premium’s 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. The Civic Si doesn’t offer dual zone air conditioning.

Compared to the Honda Civic Si, the Toyota GR Corolla eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries with its optional integrated Homelink® universal remote controlled from the rear view mirror.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Toyota GR Corolla Premium/Circuit Edition has a standard wireless phone charging system (Qi) in the front center console. The Civic Si doesn’t offer wireless personal charging.
