The Toyota Corolla GR hasn’t even arrived yet and the automaker is now announcing a new special edition model with even more torque and other performance upgrades. The GR Corolla Morizo Edition is named for the pseudonym used by Toyota president Akio Toyoda when he goes racing.
While the Morizo Edition is street legal, it’s really tuned to be even more hard core on the track than the already speedy Circuit edition. The Morizo retains the forged carbon fiber roof and vented bulge hood found on the Circuit. But the sure-fire ways to make a car quicker around the track are to add engine output, reduce weight and improve rigidity, all of which you’ll find on the Morizo.
The turbocharged 1.6-liter, three-cylinder engine still has the same 300-hp, but the torque curve has been sharpened, moving the peak from 273 to 295 lb-ft with a slightly narrower peak band from 3250-4600 rpm. To make the most use of this extra torque, the gear ratios in the six-speed transmission have been tightened up as well and the final drive ratio has been lowered for quicker launches.
As the late, great Colin Chapman said many years ago, “simplicate and add lightness.” Drivers taking their toys out to track days don’t usually carry rear seat passengers. In that case, who needs a rear seat, so the Morizo dispenses with that as well other items like rear speakers. All of this helps to remove just over 100-lbs from this edition.
Maximizing the handling of any car requires a rigid structure to attach the suspension to. That structure enables more consistent control of the suspension geometry. Two more floor braces, a brace between the rear struts and 349 more spot welds all around the body and six meters of structural adhesive help to achieve the desired structural integrity.
The all-wheel-drive system has a switch that enables the drive to control the front to rear torque balance between 30-70, 50-50 or 60-40 and limited slip differentials are standard at both axles.
The two remaining seats are finished in an exclusive red and black combination of ultra suede and leather. The Morizo rides on Michelin Pilot Sport Cup 2 tires on 18-inch forged alloy wheels.
Only 200 Morizo editions will be built in the launch year in a choice of windchill pearl or matte gray. No pricing is available yet, but the Morizo edition will get to customers sometime in 2023.
