Toyota is certainly constructing its delight and pleasure, the GR Corolla, in England. Of all of the locations on the planet, it looks like an odd alternative, particularly for a Japanese megacorporation that’s had extra factories than most individuals could have footwear… of their lifetime.
Theoretically, Toyota might select to provide the GR Corolla wherever it likes. So why did it select England? Properly, Toyota flew me out to the manufacturing unit so I might discover out for myself.
The selection was removed from an accident. Toyota says that the GRC is a sufferer of its personal success, and that manufacturing capability on the automaker’s historic Motomachi plant is maxed out. A couple of 12 months in the past, Toyota realized it couldn’t sustain, so it began trying to find the best plant to choose up the slack.
Toyota GR Corolla UK Plant
Picture by: Toyota
Of Toyota’s 57 or so crops and joint ventures worldwide, about 12 construct Corollas in some capability. Of these 12, solely 4 construct the Corolla because it’s identified to western markets: Two in Japan, one in the US, and one in the UK.
Solely a kind of crops might construct the GR Corolla: Motomachi in Japan. The identical plant that when constructed the Lexus LS400, Lexus LC500, Lexus LFA, Toyota Supra, and presently builds the Toyota Century. Motomachi is the place Toyota’s halo merchandise are born, and as I used to be assured, it’s the crown jewel of Toyota’s manufacturing community. The easiest construct the perfect at Motomachi.
And as I realized, it’s no easy feat to construct a GRC. It’s a wholly separate manufacturing course of from a daily Corolla, with specialised personnel, completely different tooling, and utterly completely different strategies. For anybody plant to construct the GR Corolla, it could take a wholly new manufacturing line and a devoted employees. And Toyota would accept nothing lower than the Motomachi normal for Toyota Motor Manufacturing UK (TMMUK).
Inside TMMUK
“The goal is Motomachi,” one in all TMMUK’s manufacturing leads assures me. And that wouldn’t be the final time I’d hear that actual phrase.
Equipment clanks and bangs round me as I battle to hearken to our tour information. However the machinations of TMMUK’s major manufacturing unit ground, the place regular Corollas are constructed, fascinate me. Each 89 seconds, a freshly constructed Corolla rolls off the road. Meaning every station within the manufacturing course of has 89 seconds to do its job, so the Corolla’s manufacturing line is sort of lengthy.
There’s a station for the dashboard, windshield, and a wiring harness. One other that marries the entrance and rear subframes, together with the engine, to a Corolla in that period of time. All 4 seats go in directly, and so forth, every station taking 89 seconds or much less. Even underneath a decent timeframe, no one strikes too rapidly—all motions are fluid, cautious, and environment friendly.
‘The goal is Motomachi,’ one in all TMMUK’s manufacturing leads assures me. And that wouldn’t be the final time I’d hear that actual phrase.
The complete manufacturing line’s efficiency is judged on that concentrate on quantity, and extra particularly, across the quantity of stoppages to appropriate errors and overruns. One error stops the whole line, making environment friendly, quick, and excellent operations crucial.
For TMMUK, the road uptime goal is 98.6 p.c, that means that the road is shifting for 98.6 p.c of a whole shift. There are screens in every single place exhibiting that quantity and the way the manufacturing shift is doing relative to it. One other readout reveals the errors that occurred.
What’s extra fascinating is the strategy of correction, one thing referred to as “Kaizen.” It’s a Japanese philosophy that merely means “steady enchancment.” For those who’ve been round Japanese automobiles lengthy sufficient, you’ve in all probability heard the phrase; it’s a core tenet of the Toyota manufacturing course of.

A lot of what you’ll see across the manufacturing unit is distinctly Japanese. The employee security briefing areas are referred to as Dojos. “Hoshin,” the Japanese phrase for route, is utilized in planning paperwork. Employees, who’re referred to as Members, are educated in Japanese working philosophies and strategies, and inspired to talk up about enhancements and weaknesses.
There are even common competitions amongst groups to determine the perfect Kaizen, which might help the plant construct automobiles quicker and extra safely with out compromising high quality. At any given station or relaxation space, Kaizens are celebrated and highlighted—and the plant is positively lined in them.
You’ll see issues like reshaped 3D-printed equipment that forestall heavy instruments from falling from their holster. There’s an overhead conveyor belt that safely transports wiring harnesses from above as a substitute of from a cart. It was discovered that employees have been unintentionally stepping on connectors and breaking them; feeding it from above made it a lot much less prone to trigger harm.
The GR Corolla Line
But the star of the present is the GR Corolla line. After spending the morning seeing how regular Corollas have been constructed, Toyota ushered us additional into the sprawling facility. Instantly, the ambiance was completely different.
The place the common Corolla line sprawled additional than I might even course of, the GR line was extra… compact. It took up a few third of the dimensions of the traditional line and had far much less specialised equipment. The employees moved with the same grace, however every station did many extra duties. As a substitute of 89 seconds, every GR station will get about 22 minutes.
After spending the morning seeing how regular Corollas have been constructed, Toyota ushered us additional into the sprawling facility. Instantly, the ambiance was completely different.
As a substitute of easy, small duties being divided up, the GR line had a extra technician-focused manufacturing line, with a number of main assemblies occurring at one station. One station was devoted to the whole entrance finish of the automotive, with a couple of employees dealing with the engine bay wiring harness, consumption ducting, plastics, headlights, and some different objects. One other did the inside, dashboard, seats, wiring, headliner, and windshield in a single go.
The method was shockingly handbook. One might say a whole lot of the GR Corolla’s manufacturing was left as much as the ability of the individuals assembling it, such was the reliance on human palms. I’d nearly argue that it’s functionally hand-built.
Talking to the employees on the road revealed a course of by which GR manufacturing line members have been educated for months on the common line, after which hand-chosen for the job. Virtually everybody I spoke to—and I spoke to a dozen individuals in varied stations—was a automotive or motorsport fanatic who knew precisely what they have been constructing. The fervour and delight, and the sense of being “trusted” to construct the GR Corolla, have been palpable.
Round 13 truckloads of elements are available per day to produce the GR Corolla line. Virtually each a part of the GR Corolla remains to be Japan-made, with the engines, subframes, brakes, suspension, and main working gear all being imported.
TMMUK stamps out the our bodies and physique panels, whereas close by suppliers make the seats. Dashboards and inside plastics are largely shared with the Corolla, in order that doesn’t change. The our bodies that get stamped out are additionally subjected to further stringent checks—they’re mounted to a rig with finding pins and a particularly high-resolution scanning arm to confirm physique accuracy all the way down to a hundredths of a millimeter.
The complete line is explicitly modeled after Motomachi, although in Motomachi, they’ve Kaizened their solution to 13-minute intervals. Nonetheless, a number of Toyota chiefs have spent months serving to TMMUK develop the road, together with GR Corolla chief engineer Naohiko Saito and Grasp Take a look at Driver Hiroaki Ishiura, offering enter and high quality assurance.
On the finish of manufacturing, every automotive is measured towards what Motomachi can do, and in keeping with Saito-san, it’s pretty much as good or higher. I even heard a whisper (in Japanese) from Ishiura-san that the UK Corolla felt barely higher than the Motomachi automobiles.

The Outcome
Although we didn’t need to take their phrase for it. Toyota organized a while with the UK-built automobiles at Manufacturers Hatch circuit for us to check. Bravely, Toyota gave me virtually limitless and unsupervised observe time with my alternative of computerized or handbook GR Corolla, and I put the issues via 25 minutes of hell.
In comparison with my many experiences with the GRC again residence, monitoring them at Buttonwillow Raceway and Laguna Seca, the UK automobiles felt equivalent. England’s brisker climate positively did the automobiles a favor when it comes to cooling, however they took abuse in addition to any GR Corolla might have. Sizzling lap after scorching lap, the brakes and engine temperatures remained constant and settled in for good lengthy stints.
The expertise proves simply how stringent fashionable manufacturing procedures are. Two automobiles might be made identically a world over, and even with how handbook the GR manufacturing course of is, the standard appears fairly assured. It’s stated that Akio Toyoda himself has visited the plant a number of instances and spoken to the Members of the significance positioned on GR automobiles. That it isn’t about outright manufacturing velocity or effectivity, however about precision, care, and excessive prime quality.
“We selected the UK as a result of it’s the non secular residence of motorsport,” stated Saito-san. “Morizo is aware of the significance of the UK and wished to entry it to enhance the GR Corolla much more.”
Not all GR Corollas will likely be constructed within the UK, nevertheless. The UK is primarily offering further items for the demanding North American market. Motomachi, in the meantime, will proceed to stamp out GR Corollas as rapidly as it will probably.
“Our goal is Motomachi,” one other Member repeated to me. He continued with a problem. “I hope that sooner or later we are able to even beat them.”
