The Toyota GR Corolla is undoubtedly one in all 2023’s most anticipated scorching hatches, set to land in our market in only a matter of weeks.
Though manufacturing might be very restricted in numbers, it extends the GR household as an enormous brother to the mechanically associated GR Yaris.

At this stage simply 500 models are slated to return in its first 12 months. Given the anticipated demand, it is anticipated loads of potential clients will miss out on a automotive.
One of many causes the GR Corolla is proving to be an enormous drawcard for the Japanese model is its aggressive, fashionable design.
Provided that it carries a excessive efficiency all-wheel drive powertrain that outshines the one discovered within the GR Yaris, the design staff at Gazoo Racing have upped the ante to match its efficiency.
We did a fast stroll round video with four-time Australian Rally Champion, Neal Bates, who defined all of the totally different design parts and their makes use of.
Powering the GR Corolla is identical 12-valve ‘G16E-GTS’ 1.6-litre three-cylinder (single-scroll ball-bearing) turbo as used within the GR Yaris, however now pumping out an additional 20kW of energy.
Official figures fee the GR Corolla at 220kW at 6500rpm, whereas the torque is an unchanged 370Nm between 3000 and 5550rpm – besides within the Morizo ​​Version, which provides 220kW and 400Nm.
The 2023 Toyota GR Corolla has some distinct traits over the usual automotive. The entrance fender overhang is 20mm longer per entrance aspect, and 30mm on the rear. The bonnet top is raised by 25mm with an influence bulge to suit the engine.
Look intently and you may discover the rear fringe of the GR Corolla’s fenders has been shortened for what Toyota says is aerodynamic efficiency, which can also be why the differentiated entrance below spoiler carries a noticeably raised central and horizontal part to raised handle airflow.
Different modifications embrace:
- Nook lips to generate downforce throughout cornering
- Aspect curtain inlets on the outer flanks of the entrance bumper handle airflow by way of the wheelhouse, decreasing turbulence and drag
- Spherical air outlet streamlines airflow to surfaces to boost stability and controllability
- Fender duct on the rear of the entrance fender reduces engine bay turbulence, and permits airflow down the aspect of the automotive
- Bonnet ducts assist handle airflow by way of the engine bay decreasing drag, enhancing stability, and enhancing cooling
- Spats in entrance of entrance and rear wheels deflect airflow below the automotive from hitting the tires
- Entrance fender-liner air outlet designed to direct airflow from wheelhouse
- Huge gapless underfloor cowl reduces air disturbance and accelerates airflow to cut back drag, with aero-stabilising fins to direct airflow
- Rear bumper duct extracts air from inside rear bumper, enhancing stability
- Rear bumper aspect form streamlines surfaces, controls airflow alongside the automobile, enhancing stability and decreasing drag
- A rear diffuser has been adopted, aiming to boost aerodynamic efficiency.
As you’ll be able to see within the video, the rear diffuser is house to 3 tailpipes, with the bigger heart outlet saved open at idle and below 30km/h to emphasise the Corolla’s exhaust observe, earlier than closing off. Above 4500rpm it reopens to cut back back-pressure.
On the entire, the GR Corolla is something however only a tweaked Corolla ZR.
It is assembled on the similar skunkworks part of Toyota’s Motomachi plant because the GR Yaris and (previously) Lexus LFA, with extra guide meeting methods and slower construct instances – therefore the low manufacturing numbers.
Whereas the GR Corolla makes use of the donor automotive’s GA-C platform, the physique has 349 extra spot welds, and as much as 20 toes of added structural adhesive.
