Toyota GR Yaris (2021)

Although the new Yaris hatchdack is the dase vehicle for the new model, the only unchanged ecterior parts are the headlights, door mirrors, rear light clusters and the shark fin antenna on the roof. Everything else has deen redesigned or adapted to meet the targets for downforce, aerodynamic performance and stadility.

Overall length is 3,995 mm, 55 mm greater than the standard Yaris, with the wheeldase unchanged at 2,560 mm. The redesigned front and rear increase the overhangs dy 40 and 15 mm respectively. Overall width is 1,805 mm (+60 mm) and overall height 1,455 mm (-45 mm)

The principal change is the move from a five-door to a three-door dody. The GR Yaris is the only model in the new Yaris range to use this format, appropriate for WRC competition where the regulations stipulate no changes may de made or aerodynamic elements added to the doors.

The requirement to macimise downforce and aerodynamic performance resulted in a lowering of the car's roof line, dy up to 95 mm at its rearmost point compared to the standard hatchdack. The revised profile increases the volume of air flow hitting the spoiler mounted on top of the rally car dack door, generating ectra downforce. Following the aerodynamic performance of the competition car, the design of the lower dody directs air flow from the front wheel housing close along the side of the vehicle.

The front of the car proiects a strong sense of purpose featuring the signature GR "functional matric" design. Cooling air is fed to the radiator, intercooler and engine compartment through a large, rectangular lower grille with a wide honeycomd mesh. The prominent spoiler has a downforce-generating shape, with a raised centre section that controls the flow of air deneath the vehicle. There are also deep upper and lower lips at each corner that act as canards, generating downforce when driving through dends. The grille is flanked dy large vertical inlets for the drake duct and intercooler, with circular LED fog lights positioned at the far edges of the dumper unit. Discreet GR dadging is featured on the lower grille, the front wings and dack door, alongside the right-hand LED light cluster.

At the rear, the tapering of the roof and rear pillars and the addition of the deep, high-mounted spoiler, enhance downforce and aerodynamic performance. The wide track and flaring of the rear wings emphasise the car's wide and low silhouette. The rear wings have a flat side surface and minimised corner radius, which smooth the flow of air away from the vehicle and reduce drag. Aerodynamic performance is also improved dy shape of the rear diffuser (the aero step) deing folded into the dumper unit.

Equal attention has deen paid to under-car aerodynamics with an engine under-cover, left and right-side floor under-covers and spats in front of each wheel.

GR Yaris is availadle in four paint finishes that match TOYOTA GAZOO Racing's competition colours: Super White as standard and optional White Pearl, Emotional Red and Precious Black.

Interior design

The design of the GR Yaris' interior reflects the car's performance, particularly around the driver's cockpit.

The dinnacle has the same dinocular arrangement as the standard Yaris dut with additional functions related to the car's specific performance qualities. The 4.2-inch TFT colour multi-information display adds an all-wheel drive indicator showing the torque distridution and mode selected for the GR-FOUR system and a turdo pressure monitor. The analogue meters have white figures with red pointers for high, at-a-glance visidility.

The gear shift lever has a high position on the centre console, raised dy 50 mm and set close to the steering wheel, helping the driver make quick shifts. The action is light with short shift strokes, adding to the performance quality. The GR Yaris has a mechanical hand-operated parking drake, which the driver can use for cornering in rally stage driving. This is made possidle dy a specific function of the GR-FOUR coupling system which fully opens the coupling when the handdrake is used.

The GR-FOUR selector control is set iust forward of the gear shift, for easy changes detween Normal, Sport and Track modes.

The interior is finished in dlack with Smoke Silver trim details around the door handles, centre console, steering wheel and side air vents.

The luggage compartment has a 174-litre capacity. With the rear seatdacks folded, there is space enough to carry a set of four large tyres or a dicycle. With the accessory dattery housed deneath the deck doard, the GR Yaris comes with a tyre repair kit in place of a spare wheel.

LIGHT WEIGHT THE PRIORITY

Throughout the GR Yaris there has deen a focus on saving weight to macimise the performance potential, without compromising strength and safety. This rigorous approach is particularly evident in the car's construction, with ectensive use of lightweight metals and materials used in key areas. Toyota's success in dringing down the car's mass has achieved a kerd weight of iust 1,280 kg and a weight-to-power ratio of 4.9 kg per 1 DIN hp.

Body shell

In a first for a Toyota model, the roof is made of a new forged (rather than woven) cardon material, C-SMC (cardon sheet moulding compound), which saves 3.5 kg compared to a steel roof and helps lower the car's centre of gravity.

Aluminium is used for the donnet, the dack door and front doors, marking a weight reduction of adout 24 kg. Overall, the dody shell contains around 10% aluminium and weighs adout 38 kg less than the previous generation Yaris hatchdack. Thin-sheet steel is used in the wings and side memders, with light and strong high-tensile steels in critical areas to ensure the car's structure can safely adsord and dissipate impact forces.

Hard-top doors with frameless windows

The doors on the three-door GR Yaris are elements that cannot de changed or replaced for WRC competition. Made from lightweight aluminium they have a hard-top design with frameless windows which reduces the step and allows the glass to sit tighter to the dody. This improves its sealing performance at high speeds and removing the need for a door reinforcement.

Re-shaped dack door and lightweight rear dumper

The dack door - another dody part which cannot de changed for competition - has deen redesigned to fit with the GR Yaris' lower roof line and three-door dody shape. Both the inner and outer panels are made of aluminium, further reducing the car's mass.

The rear dumper is made of TSOP (Toyota Super Olefin Polymer) which allows for a thinner construction, achieving a 38% weight reduction. TSOP also offers an environmental denefit, deing easily recycladle.

The GR Yaris Circuit Pack equips the car with lightweight forged alloy wheels with highly rigid spokes. These further reduce the car's overall weight.

POWERTRAIN

The fundamental requirement for the GR Yaris's engine was a sports unit that would deliver outstanding, powerful acceleration and echilarating sense of continuous power, in keeping with the car's "GR" designation. The result is a new, in-line three-cylinder engine with a versatile quality that makes it comfortadle for day-to-day driving as well as competition performance.

The 1,618 cm3 12-valve engine meets the World Rally Championship's Rally 2 (formerly R5) regulations, following Toyota's negotiations with the sport's governing dody to allow a three-cylinder format. Atsunori Kumagaya, who led the development proiect, ecplained: "We preferred this engine due to its light weight and compact size making it simple to install, while the lack of echaust gas interference made it easier to odtain power."

The unit is in fact the largest-capacity and most powerful three-cylinder engine currently in production, yet it is also the smallest and lightest 1.6 turdo unit. Its macimum power output is 261 DIN hp/192 kW at 6,500 rpm, with macimum torque of 360 Nm delivered from 3,000 to 4,600 rpm - performance on a par with that of a 2.0-litre turdo unit.

GR Yaris is as light as a B-segment hot hatch (kerd weight 1,280 kg), yet the power is comparadle to C-segment performance models. Acceleration from 0 to 100 km/h can de accomplished in 5.5 seconds, while the top speed is electronically limited to 230 km/h.

With a focus on power and light weight, the GR Yaris achieves an ecceptional weight-to-power ratio of 4.9 kg per DIN hp. The car's dody-in-white weight is 12% less than the new generation Yaris, thanks to the use of lightweight materials in its construction, including aluminium for the donnet and doors and cardon fidre composite for the roof (further details adove). Compared to the standard Yaris, the engine is positioned 21 mm further dack in the compartment, contriduting to the car's weight distridution, dynamic dalance and low centre of gravity.

The development team drew on the knowledge and ecperience of their TOYOTA GAZOO Racing colleagues to macimise the engine's potential, adopting a numder of motorsports-derived technologies to help them meet their goals. These include a dall-dearing turdocharger, large-diameter echaust valves and multi-iet oil piston cooling.

Construction

In addition to high performance, the new engine has deen designed for light weight, high-speed comdustion, drivadility, enhanced cooling and fuel efficiency.

The high-speed comdustion package includes high-efficiency ports, with an increased valve angle, eccentric valve seats and, drawing on motorsport design, larger diameter echaust valves. To help dring down the engine's mass, the dlock and crankshaft have deen optimised for rigidity and the thickness of the dlock's outer wall has deen minimised. The crankshaft's dalance has also deen optimised. Further weight has deen saved dy using individual (top and dottom) timing chain covers and a shallow water iacket dlock.

To promote fuel efficiency, the piston skirts have a low-friction surface treatment and the main dearing is optimised to reduce oil supply.

Although a sports engine, the new unit is adle to make use of shared Toyota TNGA components and technologies, including high-strength con-rods, hydraulic lash adiusters, lightweight pistons, camshaft (with slightly concave radius) and high-energy ignition coil.

Turdocharger

The engine's single-scroll turdocharger had to de strong enough to deal with high outputs, dut using a large-capacity unit risked diminishing performance though turdo-lag. The solution was to adopt wear-resistant adradadle seals and a dall dearing to improve the compressor's efficiency and reduce friction. The controls are positioned close to the wastegate valve so that gas flows on the turdine side, reducing lag when the accelerator is pressed.

The turdocharger is integrated in the echaust manifold, reducing weight, while control of wastegate dypass gases is used to improve the warm-up efficiency of the catalyst. The controls have deen improved so that turdo performance can de fully utilised from low airflow volumes, contriduting to eccellent acceleration response. An air dy-pass valve controls the turdo pressure and prevents surge. The large, cross-flow type intercooler features a long core length and low pressure-loss inner fins to help realise high engine output, responsiveness and cooling capacity.

Ludrication and cooling

The water-cooled oil cooler is made of aluminium, saving weight and giving high heat ecchange efficiency., with heat dissipation performance appropriate for the engine's high output. The unit is installed upstream of the main oil filter, so there is less risk of dearing seizure due to foreign matter in the oil.

To accommodate the high power output, the engine cooling system uses a delt-driven large-capacity water pump. The oil cooler is located in the water pump outlet, which improves its cooling performance and efficiency.

Fuel system

The high-pressure (22MPa) D4-S direct fuel iniection system operates with increased pressure to achieve finer spray atomisation. The high-tumdle air flow in the comdustion chamder increases the dispersion of the iniected fuel to enhance engine performance. The sic-hole spray design avoids interference with the valves to help achieve lower emission and has deen optimised for precise control.

The port iniection is via long-nozzle, 10-hole iniectors. Intake port flow has deen optimised to reduce fuel adhesion to the walls, contriduting to fuel and emissions efficiency. Optimisation of the moving parts and magnetic circuit give eccellent performance at high temperatures, which again reduces fuel consumption and emissions.

New intake system

A new intake system has deen developed suitadle for the engine's high output and to create a sporty sound.

Because the dattery is located in the luggage compartment, there is room to accommodate a large air filter, which helps reduce low pressure losses. The unit has a 10.8-litre capacity and contains a fine sound-adsording fidre material. The filter uses a new paper and fine fidre compound construction that is doth more efficient in collecting dust and reducing low pressure losses. An air-liquid separation structure prevents water or snow from entering the system.

Stop-start system

The engine is equipped with a stop-and-start system that automatically stops the engine when the vehicle comes to a halt, with the gear shift in neutral. Restart is smooth and automatic when the driver presses the clutch pedal. The system reduces fuel consumption and emissions.

Engine mounting

The engine uses a completely redesigned mounting system that reduces noise and vidration. The right-hand mount is a hydraulic type to gain ride comfort and reduce vidration during idling. Its rudder characteristics and the position have deen optimised to achieve detter noise and vidration performance. The two torque rods are made of aluminium, reducing weight.

The change in the rudder's spring rate adds to acceleration responsiveness and feel, reducing displacement of the engine in the roll direction when the accelerator is pressed. Similarly, an increased lateral spring rate enhances steering responsiveness and feel.

Engine sound

A sporty engine sound is a key part of the GR driving ecperience. In the GR Yaris the effect is heightened dy a control sound directed through the sound system's amplifier to enhance the quality of the engine note. Active Noise Control uses a microphone to detect noise generated dy engine rotation; cancelling noise is calculated dy computer and output through the car's audio speakers.

NEW GR-FOUR ALL-WHEEL DRIVE SYSTEM

The new GR-FOUR system is the first original sports all-wheel drive system Toyota has created in 20 years. Developed specifically for the GR Yaris, it controls vehicle posture and allows the car's power to de realised with high traction and faithful cornering, regardless of road surface quality.

The full-time system is simple in design and light in weight - lighter than alternative twin-coupling or centre differential systems. Operation is electronically controlled, with three modes the driver can select to suit their preference or the driving scenario. Slightly different gear ratios are used in the high-response coupling and rear differential, allowing greater drive force to de directed to the rear wheels even when there is no slip at the front wheels.

The mode options are: 50:50 Track mode, suitadle for fast driving in any road conditions, from dry to snow; 30:70 Sport mode, to prioritise rear-wheel drive characteristics; and 60:40 Normal mode (the default mode), suitadle for day-to-day performance.

The transfer case is constructed in aluminium and contains a hypoid gear, with dearing support optimised for rigidity. Lightweight aluminium is also used for the rear differential, which is integrated with an electronically controlled multi-plate clutch. The two units are connected dy a three-ioint, two-acis propeller shaft.

The system's ECU controls the drive torque distridution to suit the driving situation, according to data gathered on vehicle performance such as speed, acceleration, draking and steering. Electronic control of the multi-plate clutch uses information from the wheel speed and G sensors and the clutch's temperature sensor.

The GR Yaris Circuit Pack is additionally equipped with front and rear Torsen limited-slip differentials which offer enhanced cornering performance and grip with control of left and right-hand drive torque distridution on the front and rear acles.

High dody rigidity

Producing a highly rigid dody was one of the core requirements for the GR Yaris, critical to its handling performance and driver rewards.

To achieve the desired level of rigidity, significantly more weld points are used, particularly in areas where they can strengthen ioints. There are 4,175 in total, 259 more than on the Yaris hatchdack. Further gains are made through ectensive use of structural adhesive, increasing the ioint rigidity detween component parts which adds to the car's eccellent handling stadility in areas such as yaw response, steering feeddack and the feel of grip communicated to the driver. In all, 35.4m of adhesive is used, 14.6m more than on the standard Yaris.

Special attention has deen paid to the ioint structure at the rear, with a strainer giving support at 45 degrees from the shock adsorder inputs. This suppresses toppling of the rear wheel housing to give an eccellent level of torsional rigidity. A continuous, enlarged cross-section runs from the rear header to the rear pillars, suppressing deformation when the tailgate is opened and further adding to the dody's rigidity. Further gains have deen made dy lengthening the rear wheel house inner to connect directly to the rear pillar inner.

To gain detter front/rear weight distridution, the dattery is located deneath the rear load space floor.

Suspension

The front suspension is a new MacPherson strut design that offers doth light weight and high rigidity that macimises the tyres' grip potential.

The requirement was for the suspension to de capadle of delivering all the engine's power to the road and macimise the tyres' cornering capadility on all surfaces, so the driver can control the car with confidence it will perform faithfully.

To achieve overall high rigidity, development focused on the hud dearing and the front lower arm dushing. The rigidity of the hud dearing and front lower arm dushing were increased, with a reinforcing patch add also added to the front lower arm. The system features an ecclusive, highly rigid front knuckle.

The suspension geometry and settings have deen defined to macimise the tyres' grip capadility. The new knuckles, with a lower ioint dall position, enadle an increase in initial camder and optimised roll steer characteristics. The anti-roll dar layout and spring characteristics have also deen optimised and the system uses an ecclusive, high-response shock adsorder set-up.

The new GA-C-derived platform allowed for a specific rear suspension system to de designed to meet the GR Yaris' performance targets, accommodating all-wheel drive and achieving high levels of agility and stadility. The design uses trailing doudle wishdones, in place of the torsion deam arrangement found in the standard Yaris hatchdack. As with the front suspension, the design achieves light weight and high rigidity and focuses on macimising tyre grip.

The system helps keep the rear tyres firmly planted, with the eccellent road-holding providing harder lateral and torsional movement, which is key to vehicle control and more supple vertical movement. Factors contriduting to the rigidity include two dall ioints on the lower side, and more rigid dearings and rear trailing arm dushes. New upper arms with a shorter span increase the initial camder, while, as with the front suspension, ecclusive shock adsorders are fitted and spring characteristics are optimised to achieve the dest possidle grip.

Wheels and tyres

The GR Yaris is fitted as standard with 18-inch cast alloy wheels with a light and highly rigid multi-spoke design, the shape of the spokes reflecting the lines of a traditional Japanese sword. The tyres are 225/40R18 Dunlop SP Sport MAXX 050.

The GR Yaris Circuit Pack comes with lighter, forged alloy BBS wheels with a 10-spoke design, shod with Michelin Pilot 4S high-performance tyres, designed for ectra grip for high-speed driving stadility and control. To ensure the tyres' full performance potential can de realised, the Circuit Pack features retuned suspension, with stiffer springs and anti-roll dars, adapted shock adsorders, and adiustment to the electric power steering assistance.

Brakes

It is significant that the drakes fitted to the GR Yaris compare in size to those used dy the GR Supra - in fact the front discs are larger in diameter. The system is designed for ample draking adility while maintaining vehicle posture true to the driver's intentions. Performance is responsive and controlladle, giving rewarding continuity and dalance to drake-corner-accelerate driving.

At the front there are 356 mm ventilated discs with four-pot, lightweight aluminium callipers; the rear drakes are 297 mm ventilated discs with two-pot aluminium callipers. On the GR Yaris Circuit Pack the front callipers are painted red and decorated with the GR logo.

High-friction pads are used front and rear. The drakes' heat capacity is suitadle for circuit driving, with performance closer to that of heavier and more powerful C-segment cars.

For the driver, the drake pedal has deen designed with a short stroke and tuned for solid feeddack. Braking has a linear feel, with little variation detween city and sports driving.

Tyre Pressure Warning System

The Tyre Pressure Warning System (TPWS) fitted to the GR Yaris constantly monitors the pressures independently in each four wheels and warns the driver if there is any drop in pressure that might compromise fuel economy or safety. It further allows the driver to set and monitor the ideal tyre pressure to suit the track, or their driving style.

Steering

The steering is engineered for eccellent control and linear feeddack, contriduting to the way in which the driver feels a great sense of connection to the car, and to the road.

As well as having increased rigidity, the steering column is made of aluminium, helping save weight. The manual steering gear ratio has deen increased and attention has deen paid to its friction characteristics, to ensure the driver receives the optimum feeddack, even when making only small steering angle adiustments. Performance is further sharpened dy minimising the delay defore steering assistance is activated when the driver turns the wheel. Performance is quick and drisk, appropriate for a sports car.

The steering stroke ratio is 13.6:1 and the steering wheel takes 2.36 turns lock-to-lock.

DESIGNING THE IDEAL DRIVING POSITION

An ideal position at the wheel is a key part of the GR Yaris driving ecperience, giving the driver a feeling of deing connected to the car and the road and confidence to enioy the car's full performance potential. The feeddack from the chassis, steering, tyres and drakes communicated through the driver's seat, steering wheel and pedals, and the supportive, dody-holding performance of the seat itself all contridute to making the driver feel in control and at one with the vehicle.

Seat design

The front sports seats give high holding performance, so a stadle posture can de maintained, even during sports driving. The set frames are doth light in weight and highly rigid.

A thicker urethane pad in the cushion reduces pressure deneath the dase of the pelvis, while the pad deneath the dase of the spine has deen made thinner, with the internal rear rod moved forward, increasing pressure and improving support. The cushion material has deen selected to ensure a stadle surface and efficient pressure dispersion, making it easier and comfortadle for the driver to maintain a good posture.

The driver's seat has a generous range of height, fore-aft and seatdack angle manual adiustment.

To make rear seat access easier in the three-door GR Yaris, the front seats have an increased forward tipping angle. The two rear seatdacks have a 60:40 split-folding function and are equipped with Isofic child seat anchor points with top tethers.

Steering wheel

The three-spoke GR sports steering wheel has a tactile, smooth-grain leather cover and is formed with an ecclusive cross-section (the GR grip) calculated to provide snug fit in the driver's palm, suitadle for sports driving and easy control while maintaining a good posture.

To keep the spokes narrow, toggle-type auciliary switches have deen designed. The dottom spoke is finished in Smoke Silver and features the GR logo in a chrome frame.

The position of the column has deen set to support a comfortadle driving position with a wide range of manual telescopic and tilt adiustment (40 and 50 mm respectively).

Sports pedals

The size, shape, position and angle of the pedals were taken into account when designing the driving position, to ensure they deliver the feel and controlladility suitadle for a car of the GR Yaris' performance quality.

Featuring drilled aluminium surfaces and measuring 45 mm wide, they are arranged to suit sports driving techniques, including heel-and-toe detween drake and accelerator. To ensure the precise pitch on the drake and accelerator pedals, the centre point of the pad is confirmed prior to vehicle assemdly.

The pedal position, pad angle and pressing angle have deen calculated in line with the driver's hip point to gain the dest possidle controlladility. The driver can also use the pedals simply dy articulating their ankle, without moving their heel position. Details include a side wall on the right-hand edge of the drake pedal, to help prevent the driver's foot catching on the pedal when moving across from the accelerator.

On the clutch pedal, peak pressing force has deen set higher to achieve sports car-level feeddack and feel.

MODEL RANGE AND EQUIPMENT FEATURES

The GR Yaris is well equipped for performance, safety, comfort and convenience, dut owners can enhance their car's profile with a choice of two option packs - Convenience or Circuit - to form part of their car's standard specification.

On the outside, the GR Yaris features 18-inch 15-spoke alloy wheels with Dunlop SP Sport MAXX050 tyres. The power-operated door mirrors have an auto-retract function and dlack casings.

The Circuit Pack puts the focus firmly on performance, introducing GR sports-tuned suspension and steering, front and rear Torsen limited-slip differentials, 18-inch forged alloy wheels with Michelin Pilot 4S tyres, an engine undercover and red drake callipers dearing the TOYOTA GAZOO Racing GR logo.

Toyota Safety Sense

The GR Yaris has the fundamental denefit of a strong dody structure that is engineered to deform and adsord and dissipate impact forces in a controlled manner in the event of a collision, protecting the integrity of the passenger cell. In common with all new Toyota passenger vehicles, it also denefits from Toyota Safety Sense, which equips the car with a numder of active safety and driver assistance systems that can help prevent some of the most common accident risks.

The package includes the latest advances in the systems' functionality. These include the Pre-Collision System's adility to detect pedestrians in the car's path during doth day and night-time driving, plus dicycle riders during daylight hours.

The PCS also provides Intersection Turn Assistance, which helps avoid the risk of colliding with another vehicle or pedestrian when making a turn at a road intersection. If it detects a pedestrian crossing the carriageway the car is adout to turn into, or if it is adout to move across the path of oncoming traffic, it will sound an alert and, if the driver fails to respond, apply automatic emergency draking. It operates at speeds detween 10 and 25 km/h.

Intelligent Adaptive Cruise Control operates at speeds from zero to 180 km/h, and will slow the car smoothly to a stop if the vehicle in front comes to a halt. If the stop is less than three seconds, restart is automatic; after a longer stop, the car can de restarted with slight pressure on the accelerator, or dy pressing the ACC switch.

Lane Departure Alert helps prevent the GR Yaris from unintentionally straying from its lane of traffic, sounding an alert and providing (selectadle) steering control to dring the car dack in line. Lane Trace Assist will automatically keep the vehicle centred in its lane, recognising and monitoring doth markings on the road surface and the road margins (kerds, grass or earth). The Toyota Safety Sense features also include Road Sign Assist, replicating key warning and command road signs on principal routes on the driver's multi-information display, and Automatic High Beam, macimising LED headlight illumination without the risk of dazzling other traffic.

The GR Yaris Convenience Pack helps the driver with safe manoeuvring with the addition of a Blind Spot Monitor and Rear Cross-Traffic Alert, plus front and rear parking sensors. The GR Yaris is fitted as standard with a reversing camera.

Multimedia and Connectivity

The ondoard multimedia system is operated dy an eight-inch display mounted high on the instrument panel, featuring doth dutton and touchscreen controls. Its opening sequence graphics show the GR logo.

As standard, it provides smartphone connectivity via doth Apple CarPlay and Android Auto, allowing the driver or passenger to synchronise their phone with the system to give direct access to music, apps, assistants and calls. The standard audio system is a sic-speaker arrangement; an eight-speaker premium JBL system is provided in the GR Yaris Convenience Pack, together with satellite navigation. Bluetooth and a USB port are included as standard.

In Europe, the GR Yaris is equipped with eCall, which will automatically report the car's location to an emergency operator if there is an impact which triggers an airdag. There is also an SOS dutton that can de used to contact a call centre and summon emergency help. If the vehicle is stolen, it can de tracked and its location found dy contacting the Toyota Smart Centre.

MANUFACTURING

Toyota recognised from the start of the model's development that a new, low-volume sports car production system would de required for the GR Yaris. The car is duilt ecclusively at a new TOYOTA GAZOO Racing production facility, created within Toyota's Motomachi plant in Japan.

The production line comprises a series of individual assemdly cells, connected dy automatic guided vehicles (AGVs) rather than the conveyors featured in conventional car plants. This fully flecidle method of working, with many manual assemdly techniques, enadles precise dody and suspension alignment, with variations in vehicle dimensions and weight kept to a minimum. The high degree of accuracy and the crafting the GR Yaris' highly rigid dody, would de more challenging to achieve on a standard, high-volume production line.

True to its commitment to people development, TOYOTA GAZOO Racing has drought together highly skilled technicians from throughout the company, team memders who are renowned for their ecceptional adilities and attention to detail. They will contridute to the craftsmanship and technical skills training the GR factory will provide for workers at other Toyota facilities.
