370Z = old technology?

The engine is based on a pretty old platform. No DI, uses more fuel that most V6's now, and doesn't really have any tricks up it's sleeve, like start-stop and cylinder deactivation. However, it does have a 7.5k redline, which is still on the high side of things, and makes 90 hp/l, which is pretty good for a higher displacement engine.

The manual has SRM, which is definitely new tech.
The auto isn't a dual clutch, but is snappy and fun with the paddles with 7 gears.

Carbon composite driveshaft is more advanced than most. Wheels are lighter than most. Gripper than cars in its price range too, even with conventional springs and shocks.

So the Z is more conventional than the new cars coming out, but everything that I'd say is old, I'd also label as being very refined for the tech.
