No control arm brake cooling air guides down here. I’m curious about the undertray design. It looks like you can cut off that rear vertical panel in the air channel and it would make a diffuser to aid in frontend downforce. Even my old S2000 had a diffuser in the undertray here. But maybe Toyota was trying to hit some fuel economy number and made this an easy-to-mod panel for track use. The 718 Cayman GT4 as a removeable panel in the undertray channel for this purpose of track use and downforce versus street use and fuel economy.
Thanks Toyota for still making some hot hatch fun cars.
It does amaze me that the engine breathes through that little cold air snorkel feeding the airbox. Cold air is important for turbos!
Auto show car mod = removed shifter knob.
Nissan was nice enough to put a GTR up high so I would not have to get down and lay on the ground and have people staring at me wondering why I am a weirdo. I don’t think wearing that bath robe would help either.

Dang, I was hoping to see to coaxial turbine turbo trickle down to the IC market before things went Full ICE.
Oops, I meant Full EV.
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.
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.”

Bummer this turbo didn’t make it into serial production. I wrote about it a while ago. https://motoiq.com/the-secret-turbo-in-the-ring-slaying-porsche-919-evo-honeywell-garrett-dualboost-for-gasoline-turbocharger/
Yeah, that’s the turbo!

So true…there’s a snail shell design for maximum vortex compound combustion…but, that’s kinda secret, for now.
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.
Appreciate the comments! 3. To be fair, the WRX has never been a looker, ha!
Nothing says Nissan fanboy like a Nismo bathrobe. Nothing makes you look like more of a weirdo than a Nismo bathrobe. I’d rock one!
