280zx was a different or heavily modified chassis with different suspension and more weight.

Obviously Z31 300ZX totally different, as was Z32 300ZX.


This brings me to a point I keep thinking I may be correct about: Nissan is unlikely to use "400" to designate the Z. I am not quite sure where "400" comes from, maybe the anticipated 3.0TT HP? However, Datsun/Nissan never did that before.
Also, they didn't require increasing the number either as Z31 and Z32 were both "300" despite having several HP levels and being 2 totally different cars.

For Nissan to use "400" would be a deviation from the heritage, which has been very consistent. I suspect it will either drop the numbers (I am unsure about Fairlady) or Nissan will call it "300Z" This would be different than the Z31 and Z32 as they were called "300ZX".

Also, I keep hearing publications and YT videos say the car will also use the 7AT. I sure hope not! Nissan has a 9AT now and it is regarded as a much better trans than the 7AT. I have a 7AT in my Q60, it's "OK" but I wouldn't buy it again.
I'm definitely getting the 6MT Z.
