Again within the Seventies and early Eighties after I was going to the drag races with my dad, the occasional flat-4-powered Volkswagen would seem amongst a sea of V-8 Fords and Chevys. The little rear-engined, air-cooled Beetles would buzz down the quarter mile slower than many of the muscle automobiles that populated the monitor, however each as soon as in awhile one would put up a decent ET.
“Willpower!,” my dad would shout, in reference to the flat-4 motivation that made them so fast. In the meantime, the muscle automobiles would rely totally on big-displacement V-8s.
The 2023 Toyota Corolla GR is chock filled with willpower, and it’s simply as spectacular as these fast drag Beetles from many years in the past. Powered by a tiny 1.6-liter turbocharged 3-cylinder, it could’t depend on displacement to make it fast. As an alternative, it makes use of a heaping serving to of turbo increase and the willpower of the fanatic Toyota engineers who turned an automotive equipment right into a enjoyable sizzling hatch with analog attraction.

The 12-valve, dual-overhead-cam engine, identified internally as G16E-GTS, can also be used within the well-reviewed GR Yaris, which we don’t get within the U.S. That engine has 20.3 psi of increase and most turbo engines get about 15 psi. However within the GR Corolla, Toyota engineers shove 25.2 psi of turbo increase down the throat of the engine. Within the limited-run (just 200) Morizo Edition, that will increase to 26.2 psi of increase. Each variations make 300 hp, however the additional increase within the Morizo will increase torque from 273 lb-ft to 295 lb-ft.
The engine makes use of some motorsport expertise to wring 300 horses out of three cylinders, together with a machined consumption port, giant diameter exhaust valves, and multi-oil jet piston cooling. It additionally employs each port and direct gasoline injection, a system Toyota calls D-4S, to maximise energy and gasoline financial system, although it’s not very environment friendly given its measurement, incomes the GR Corolla estimated gasoline financial system scores of 21 mpg metropolis, 28 freeway, 24 mixed.
The G16E-GTS asks drivers to beat on it. With a single-scroll ball-bearing turbo and a lot increase, peak torque takes its candy time to reach, hitting its plateau from 3,000-5,000 rpm. It spools up even later within the Morizo, arriving at 3,250 rpm and dropping off at 4,600 rpm. For those who simply drove it conservatively on the road, you may not understand it’s highly effective in any respect—in spite of everything, we seldom exceed 3,000 rpm on our day by day commutes.
On a two-plus-mile monitor on the Utah Motorsports Campus at Toyota’s media drive program, meaning I’ve to rail on it to entry the ability. Fortunately, the engine revs freely, and low gearing helps me get into the ability band shortly. The facility doesn’t hit onerous. As an alternative it takes a beat or two to construct, then pushes the automobile ahead to hit 60 mph from a cease in a contact beneath 5 seconds (Toyota quotes 4.99 seconds for the Core and Circuit Version and 4.93 seconds for the Morizo). Willpower!
The little three offers its all on the monitor. It’s each enjoyable to shift and vital to take action repeatedly to maintain the engine on boil between 3,000 and seven,000 revs. A graphic tachometer flashes grey, orange, and eventually crimson because the engine approaches, then hits, its 7,000-rpm redline. With a shorter remaining gear ratio, that rev band feels meatier and simpler to entry within the Morizo, regardless that the max torque band is smaller. On this 16-turn monitor, for example, the Morizo requires 5 upshifts into fourth gear in comparison with a median of three within the different fashions as a result of the shorter gearing makes it rev increased extra typically.
A 6-speed handbook transmission performs these shifts. The gearbox has quick, constructive shifts and a clutch with reasonable weight and a barely grabby takeup level that may result in stalls when shifting to first gear throughout the first few drives. Toyota calls it the iMT transmission in reference to its commonplace downshift rev matching that may be turned off (on is the default) by way of a button on the decrease sprint.

Making a handbook the one selection is one signal that the GR Corolla was developed by fans for fans. One other clue? The Morizo mannequin is called after the racing identify of Toyota CEO, Akio Toyoda, who has to log out on the driving character of each Toyota sports activities automobile earlier than it makes it to market.
The willpower of Toyota’s fanatic engineers doesn’t finish with the engine. Whereas the Corolla hatchback’s roots are pure financial system automobile, the GR workforce buttoned it up fairly properly. To agency up the physique construction, they added underfloor tunnel and rear wheelhouse braces, plus 349 spot welds and 9 ft of bonding materials. The Morizo will increase the quantity of bonding materials to virtually 20 ft, and likewise will get two rear cabin braces.
Each GR Corolla has a MacPherson-strut entrance suspension with track-tuned dampers, springs, and stabilizer bars. Double wishbones on the rear make room for the model’s GR 4 all-wheel-drive system, which was developed with an help from Toyota’s Gazoo Racing World Rally Crew. The Morizo improves the rear suspension with track-tuned coil springs and monotube shocks out again. The Circuit and Morizo each additionally come commonplace with entrance and rear Torsen limited-slip differentials, that are elective on the Core. A uncooked, cast carbon-fiber roof additionally helps decrease the middle of gravity on the Circuit and Morizo fashions, and the Morizo does away with a rear seat within the identify of weight financial savings.
Each mannequin—Core, Circuit Version, and Morizo Version—is offered for me to check at this monitor drive, and all the Core fashions have the $1,180 Efficiency Package deal, which incorporates the LSDs. For monitor laps, firm reps advocate the setting GR 4 to its Monitor mode, which units a 50/50 torque break up, and that’s the primary mode I attempt in a Core mannequin.
I’m smitten from the beginning. In an more and more digital automotive world, the GR Corolla feels very analog. The GR crew elevated the Corolla’s steering ratio 7% from 13.7:1 to 12.7:1 and it instantly reveals itself as fast and direct, with plenty of really feel for what’s happening on the entrance wheels. Driving with the home windows open, I may also hear what’s occurring on the wheels. As I toss the automobile into corners, the usual 235/40R18 Michelin Pilot Sport 4 tires scrub when there’s an excessive amount of steering angle, and cool down after I unwind the wheel to stability the automobile. If I had been blindfolded, I’d have the ability to inform the distinction between grip and push by merely listening to the tires, however who is aware of what I’d hit.

Not that the automobile tends to push, which might be anticipated for a sizzling hatch based mostly on a front-wheel drive platform. Maybe the 3-cylinder engine has one thing to do with that given it’s about 44 lb lighter than a comparable turbo-4, based on lead engineer Naoyuki Sakamoto.
With the bottom tires, if I drive too onerous right into a nook, the GR Corolla factors in the appropriate path and goes into a brief, managed slide till I can get the pace beneath management. It then does what I inform it to do by way of the steering wheel, with an help from the chosen GR 4 setting. In Monitor mode, I can really feel the entrance tires pulling the automobile by way of the flip. In Sport mode, which has a 30/70 front-to-rear torque ratio, the ability flowing to the rear axle helps the automobile rotate by way of corners. In each instances, the LSDs make sure that the ability will get to the pavement, and in both mode, this rambunctious little beast is unflappable.
These managed slides give approach to exactly carved traces within the Morizo. With its stiffer construction, a 0.2-inch decrease experience top, and particularly its sticker 245/40R18 Michelin Pilot Sport Cup 2 tires, the Morizo grips more durable and tracks more true by way of the turns. It’s a pure delight, however so are the opposite fashions. Which is greatest for you is a matter of style, very like it’s for GR 86 consumers, who can flip their automobiles into drift machines with the usual all-season tires or minimize sooner autocross occasions with the accessible summer season efficiency tires.
The automobile stops properly, too. Customary 14.0-inch entrance rotors with 4-piston calipers and 11.7-inch rear rotors with 2-piston calipers present robust stopping energy on the monitor and refuse to fade throughout a great six hours of on and off motion.
Toyota’s drive program doesn’t embrace a avenue drive, however a pair laps across the monitor’s ring street reveal that the suspension is agency however forgiving. The one doable irritant would be the automobile’s buzzy sound, however fans will discover it extra enjoyable than irritating. The engine has a three-pipe exhaust system that closes the middle pipe at 20 mph for a extra subdued expertise. It opens again up at 4,500 rpm to produce the buzzy racket drivers possible need that prime within the rev vary.

The GR Corolla’s cockpit doesn’t fairly match the automobile’s worth level, which is $36,995 for the base Core model. It’s plasticky and clearly has financial system automobile roots, nevertheless it does come commonplace with supportive cloth sport seats, silver distinction stitching, aluminum pedals, an 8.0-inch infotainment touchscreen, and a 12.3-inch digital instrument cluster with accessible readouts for the GR 4 drive mode, turbo increase stress, and g forces. The $43,995 Circuit Version will get artificial suede and artificial leather-based upholstery with crimson distinction stitching, heated entrance seats, a heated steering wheel, and wi-fi smartphone charging. The $50,995 Morizo Version has artificial suede wrap on the shift knob and steering wheel and the rear seat delete.
No GR Corolla will probably be mistaken for a pedestrian base mannequin, due to widened physique panels to cowl the broader wheels and tires, enticing 18-inch wheels, a hood bulge on all however the Core mannequin, extra entrance finish cooling ducts, a rear spoiler, the carbon-fiber roof, and the hatchback physique model itself. As an alternative of an automotive equipment, they’ll see a rowdy sizzling hatch with an perspective, they usually’ll be proper. Ought to they take it for a check drive, particularly on a monitor, they’ll additionally uncover it has the willpower to match its outward perspective.
Toyota paid for airfare, lodging, and monitor time for Motor Authority to have a ball tossing the GR Corolla by way of corners and produce you this firsthand report.
