Nerd’s Eye View: LA Auto Show 2023

Carbon fiber front undertray? I would be afraid driving that around where I live. The indentation hump in the plastic tray is interesting… Is Nissan trying to create a low-pressure zone there for aero balance?

There are quite a few NACA ducts in the rear undertrays to cool various items that are hidden. I’m surprised at how small the exhaust looks.

There is a little carbon fiber rear brake cooling air guide. It does not seem like it can provide a ton of air, but something is better than nothing.

These rear lower camber links are billet titanium with spherical bearings. I am scared to know the price.

The Z does exist! I have seen fewer than a handful out in the wild. Emelia Hartford was in the booth rocking a Nismo sweatshirt.

This WRX was in the booth without any labels. I guess it was a TR.

    1. I’m curious to see if/when more e-turbo makes it onto cars. Mercedes has a Garrett e-turbo on one of their AMG cars. Genesis has a 48V electric supercharger and e-turbo uses the same 48V. With more cars coming hybrid like all the new super cars from Ferrari and McLaren, one logical step is e-turbo. Conversely, they could just say the electric motor does the torque filling.

      1. Yeah, we have probably hit ‘Peak Turbo’ in our civilization, but I was kind of hoping to see the development of these turbos stretched out a bit more.

        “The amount of turbocharger lag plays a key role in the driver’s perceived quality of a passenger vehicle’s engine response. This paper investigates an alternative method to the conventional design of a turbocharger turbine to improve the transient response of a passenger vehicle. The investigation utilises the Ford Eco-Boost 1.6 L petrol engine, an established production engine, equipped with a turbocharger of similar performance to the GT1548 produced by Honeywell. The commercially available Ricardo WAVE was used to model the engine. Comparing the steady-state performance showed that the axial turbine provides higher efficiencies at all operating conditions of an engine. The transient case demonstrated an improved transient response at all operating conditions of the engine. The study concluded that, by designing a similar sized axial turbine, the mass moment of inertia can be reduced by 12.64% and transient response can be improved on average by 11.76%, with a maximum of 21.05% improvement. This study provides encouragement for the wider application of this turbine type to vehicles operating on dynamic driving cycles such as passenger vehicles, light commercial vehicles, and certain off-road applications.”

          1. Yeah, that’s the turbo!

          2. So true…there’s a snail shell design for maximum vortex compound combustion…but, that’s kinda secret, for now.

  1. 1. The GTD rear suspension looks to be based on the GT500 rear. Probably tweaked a bit and converted to inbound dampers. Lower arm looks very chunky, probably just a prototype still.
    The front is very interesting. Based on other photos i have found online, the vertical height difference between the multilink lower “arm” pivot points looks to be over 2 inches.
    The exhaust tips are probably very thin wall titanium, as they are made by Akrapovic.
    2. The LT6 is impressive, the bore/stroke ratio is even greater than that of the 458.
    And the design of the Z06 is what the C8 should have been from the start.
    3. That WRX thing is hideous, oh my god.
