While the Supra isn’t a huge commercial success with us, A certain number of enthusiasts, the most passionate since its revival in 2019, is a version equipped with a mechanical transmission. Toyota heard them, and now they’re granting their wish with the arrival of this 3.0 GR variant, equipped with three pedals and 6 gears to shift yourself.
A mechanic for this box 6
A development that turned out to be more complex than we imagined Since there is no manual transmission in the market for this engine, BMW has decided to offer only automatic gearboxes in this Supra’s Z4, with which it shares engine and technical infrastructure, or in the Bavarian manufacturer’s 3-Series equipped with the same 3.0 turbo. So Toyota had to make a mechanic with a manual base available in the ZF, adapt it by shortening the gear ratio, and find a clutch that can withstand 500 Nm of torque, which means it requires a little more effort on the left pedal.
Refurbished center console
We had to do some work on the ship as well. because The center console was not originally designed to receive manual control, engaging the single gears risked writing to the climate controls. Therefore, the position of the lever should be shifted back a little and reduced length to avoid this interference. Since this abbreviation requires a higher effort, Toyota used a trick to be non-prohibitive: weigh the arm up to 200g versus a little more than usually 50g. This extra mass, when actuated during gear changes, creates an inertial force that helps engage gears without too much effort.
Accuracy and relative smoothness for transmission control
And it works because This lever is quite pleasant to use without too much effort, even if the locks remain quite open and sensitive. But it fits very well with the sports philosophy of this Supra GR. And then more improvements, Toyota has planned automatic rev sync – understand an automatic heel-toe – to make gear changes smoother, especially when downshifting. An automatism that can be disabled for those who want to make their own.
Steering and suspensions have also improved…
At the same time, Toyota took the opportunity to review two of the Supra’s weak points. when it was released, we criticize: a lot of steering assistance especially for the rear axle and a bit soft with damper control. So everything for this GR with manual transmission is reinforced and These changes will apply to other Supras from mid-summer. proof that it is really necessary.
… but the rear axle is still very mobile
We were only able to complete a few laps of the circuit behind the wheel, so this will require validating our first sight on the road, but the reduction in the level of steering assistance seems to make the front axle feel better, it has a really nice grip on such an asphalt pool table. On the other hand, on the depreciation side rear axle seems to hold up a little better On the rare bumps encountered at this Monteblanco circuit near Seville, evolution doesn’t seem to be enough to remove all rebounds of the posterior. Which does not fail to provoke still excessive vertical movements of the rear axle, with the onset of loss of adhesion when the lethal 340 hp and 500 Nm torque roll over, immediately followed by anti-slip interventions to avoid causing a severe overswing.
A notification to be confirmed on the way
In short, To improve those first impressions, we’re putting these new Supras on the road throughout the summer. Because very sporty driving enthusiasts will certainly appreciate being able to choose for themselves which gear to exit the corners in. especially with this successful box order.
