I'm not going to speculate on what Nissan does and whether Toyota will put anything like the VR in the Supra. I hope not. The idea Toyota is developing a clean sheet engine which would just be a copy of a competitors decades old design doesn't make much sense to me.
Also, the N55 is built by Steyr in Graz, Austria. Same place as the Supra supposedly. |
The Z06 has gained weight along with a whole new body redesign, a different motor with new technology and upgraded interior options. Also it has to keep up with the current government mandates.
Using the LS7 to compare weights is not the greatest idea either, you'd have to directly compare to the LS9 (supercharged motor to supercharged motor) but it is still a moot point since the C7 is a complete redesign both in vehicle and drivetrain compared to the previous gen. At least when comparing C5 to C6 they shared a lot of the same underpinnings.
I just used the Nissan engine as a basis for a car in a similar category and a direct comparison to an engine that randomly got sidetracked to.
All of this is conjecture, obviously. I just would not and have never considered that the Supra would be anything but a Toyota rival to the corvette, but a bit softer overall. So, similar or higher weight and similar performance, but possibly more enjoyable over a long drive.
