If toyota removes the reinforcement add on the Z4 to replace the lack of rigidity due to the roof supression.
Between 50 and 100 kg less than the Z4.
Or same weight if toyotas want incresed the rigidity

$90,000 US for a first edition z4.....

Cant directly compare US vs European pricing, it doesn't always just line up like that. But either way, expensive as hell!

I know that's why I always wonder if I bought a MK4 or the new supra.
This is also why I am so attentive to what is driving.
If the supra has the engine X5 M40i we can draw 420Ch with slight modifications after I do not see how to get more with:
A manifold molded into the cylinder head
Cylinders surely made by electrical wire -> Cylinders oversize impossible.
Air Water system probably also what will not be very easy to modify.
The only simple thing to do well is like tada lighten the car to be faster and take a PC to optimize the ecu
The only other option would be to change the compression ratio if this is possible ..

1. The manifold is molded but the turbo is not so you can unbolt the turbo off the Y pipe and modify it. Just like the VR30DDTT engine which AMS could bolt turbos flowing up to 800hp.
2. You can bore and sleeve the block to increase the bore but i'm not sure if the bore spacing would allow much.
3. BMW A2W systems are actually quite good while their A2A were terrible. On F80 M3 people rarely upgrade them even at 30psi and 700whp levels. But there are upgrades available from like CSF radiators. I'm sure B58 will follow the same path.
4. The flashing tool is out there for the Bosch MG1 (which probably Supra will get).

Add a little more for additional options

TBH its nothing new these days, especially the thermal mangement side of this, common from most manufacturers.
for a modern design modular engine, it is actually a very robust design though.

All Spec Z4 engine

And price

All in french sorry

So i may be wrong but if what Toyota said at Madrid about Supra being 50kg lighter than Z4 , then the 2liter Supra must be around 1365kg and the 6cylinder around 1485kg which sounds reasonable i think!

*edit
i saw the other weights from official bmw germany(1480kg - 1490kg -1610kg) site so i don't think these French are correct unless they are with a 75kg driver

The Table above is DIN curb weights.
The German site is quoting EEC curb weight, which is DIN + 68kg driver + 7 kg luggage to be exact, albeit with a 90% fuel tank (remainder 10% is like 2 gallons or ~12.5lbs)

here are the details:
https://f80.bimmerpost.com/forums/s...a02e11d4c7e696e199b4f9&p=15052027&postcount=1

there are all sorts of weight standards, DIN is closest for comparisons until Car&Driver's Instrumented Test is published; as they weigh the US-spec car with 100% fuel and no driver.

But the S55 will no longer be produced after next year, not to mention that the b58 is overall a better platform

That’s the question S55 or S58 new engine
