The GR Supra was Toyota’s first global Gazoo Racing (GR) model. Since launch, GR Supra has been offered with a straight-six 335bhp/250kW 3.0-litre engine matched to an eight-speed automatic transmission. A year later, a new 254bhp/190kW 2.0-litre engine was added to the range, again with auto transmission as standard. The car has received high praise across the world.
Toyota has listened to sports car fans and customers, a new GR Supra with six-speed intelligent manual transmission (iMT) will be introduced in Europe soon, engineered to delight drivers who love the control and rewards offered by precisely timed manual shifts. A new transmission, including a new clutch, has been engineered specifically to suit the power and torque characteristics of the 3.0-litre engine.
NEW SIX-SPEED MANUAL TRANSMISSION
GR Supra’s new manual transmission has been engineered and tuned specifically for use with the coupe’s straight-six engine. At the heart of the transmission is a clutch that has been re-engineered with a larger diameter and reinforced diaphragm spring. With a larger friction area and a stronger spring, this has the high performance capability appropriate for use with GR Supra’s high-torque engine.
To avoid a sluggish take-off and a low in-gear acceleration feel, the final drive ratio has been shortened, from 3.15 (in the GR Supra automatic) to 3.46. The result is response and gearing appropriate for sports car performance.
SUSPENSION AND STEERING TUNING
All GR Supra versions – automatic and manual – benefit from retuned suspension.
GR Supra’s traction and braking have been optimised for operation with manual transmission.
NEW HAIRPIN+ FUNCTION
The ambition to make GR Supra fun to drive in the most demanding scenarios has helped inspire the introduction of a new Hairpin+ function. This is designed to allow more freedom and reward specifically when taking tight bends on an uphill gradient (more than 5 per cent) with a high-friction road surface, like those found on European mountain routes.
More “free” wheel spin can make such routes more enjoyable to drive, so Toyota has optimised engine torque control to allow a greater difference in the degree of left and right-side wheel spin.
REVISED CENTRE CONSOLE AND GEAR SHIFT
The revised layout provides a comfortable 42mm clearance between the shift knob and air conditioning panel. The feel of the gear shift in the hand and the weight of operation are part of the human sensory connection with the car, so attention has been paid to the weight and shape of the gear knob and the quality of shift engagement. As a result, Toyota adjusted the effort level to engage reverse and opted for a heavier gear knob (200g) for a more pleasing inertia effect when used.
BRAKING AGILITY AND STABILITY
The car’s behaviour when accelerating out of a corner is a key element in the “fun to drive” quality Toyota has developed for GR Supra. For the new manual version, the traction control has again been the focus of measures to ensure an ideal balance of agility and stability when exiting a corner on the throttle. TRC intervention has been calibrated to maintain stability – the car keeping faithfully to the driver’s intended line – while allowing the right amount of power for a sporty feeling.
A highly agile vehicle with high peak friction tyres may be sensitive to sudden “snap-off” oversteer – something that is hard to control with the car’s vehicle stability control (VSC) alone. To counter this behaviour, an anti-roll programme (ARP) has been adopted for both the manual and automatic versions of GR Supra. This intervenes at an earlier point with the VSC to cover any sudden loss of grip when the car’s high-response suspension setting is used.
GR SUPRA WEIGHT SAVING
The standard GR Supra 3.0-litre manual model benefits from weight-saving measures that together achieve a total reduction of 38.3kg, compared to the kerb weight of the previous, 2021 3.0-litre automatic model.
Fitting the new manual gearbox and new 19-inch alloy wheels saves 21.8kg; a further reduction of 16.5kg is gained by changing the audio system and deleting the seats’ leather upholstery, power adjustment and lumbar support – features that are part of the standard specification of the 3.0-litre Pro model. This reduction enhances the car’s handling agility.
REVISED MODEL RANGE
In the UK, the GR Supra range retains the 2.0-litre Pro automatic as the entry model, alongside the 3.0-litre Pro automatic. The 3.0-litre manual is expected to be the most popular GR Supra version, with the 3.0-litre Pro manual and automatic models positioned at the top of the line-up.
