Yeah specs are nearly meaningless at this point, as its other factors that are the limiting issue. Transmission seems to be the main one these days when it comes to speed (0-60, 1/4, top speed). Handling the tires and tuning matter far more than curb weight.
Watched some drag race video and sorry but modern auto journalism is just stupid clown antics at this point. They had it race a like 10+ year old Aston Martin like that is some worthwhile comparison. Its like everyone is trying to be Top Gear where they just spout nonsense and then rely on production quality to make it not matter. Its sad how much pontificating BS car guys resort to for no good reason just to try and make their stuff seem interesting when they're not saying anything really meaningful.
Despite them trying to effuse praise on it, all the reviews I'm seeing so far make this Z seem like even more of a dud. Heck, if anything its actually making the Supra seem better (which is ironic considering all the talk was how this was going to destroy Supra sales), since despite the whinging about it being a BMW, its like enthusiasts forgot that BMW makes cars they like (and objectively is likely better new sports car than if it had been all Toyota development because of it, unfortunately it means its almost certainly going to be a worse long term sports car). And since I find it to be a rather ugly mis-mashup of previous Z styling slapped onto the previous gen car, even the looks are a total dud for me. I'd say hopefully it'd drive 370 prices down so maybe it finally would be worth considering, but honestly there's a lot of other sports cars I'd go for over it anyway. This seems to underscore that Nissan feels like the least interesting car company these days.
I feel like Nissan should've given us what the new Supra was. Basically a shrunken, lighter true sports car, more svelte.
Another hot take: Toyota should've made the GR Yaris/Corolla into a Celica. It'd be more interesting than either of those, than the WRX, the Supra, this, or the Subie/Toyota "I'm buying this because I want a Miata but am scared I'll be called gay". But that's also why that doesn't exist, because it'd be something enthusiasts weren't pining for but would've actually lived up to the old GT-Four Celica which was basically a sports car version of the WRX. Plus if they'd have partnered with Subaru, they could've offered it as a WRX coupe, and people could pine over it like a 22B that you could actually buy.
