Another thing to note this has no port injection and compression ratio is pretty high for a turbo engine so a supercharger might make sense

It will change so much it might as well be a new engine.


Electric supercharger is kind of cheating though. The power consumed by the motor doesn't count as a parasitic loss to the engine compared to say SkyActiv-X which achieves 45% but has losses in the belt-driven supercharger.

I wonder why they moved from the previous 1.5 S/B (75 x 112.5) 500cc cylinder back to 1.2 S/B 600cc cylinder with this design. Maybe the 500cc design had too small bore (75mm) to package to center injector?

It’s pretty tight on the cylinder head:

Found this while scrolling through Pinterest. Unfortunately extremely low-res tiny photo, and reverse-image search can't produce a source.

Design proposals of next-gen Lexus IS? The top-right especially looks like a next-gen IS.

Upload it on CL and ask Carmaker1 what this is? I'm guessing it's just early design proposal of the heavily refreshed IS.

Thanks, just uploaded it there! And the design language seems too wild and new to be the current "3.5IS" I feel.. ie, the RZ-esque taillights and new-style lower grille valances.. who knows !

He responded.. turns out yeah it is an early design proposal but for the Toyota Mirai, based on the repurposed 5GS program.. explains why some of them look so similar to a Lexus design, and Toyota toned down those details a lot to look more Toyota.

No word on when we'll hear more about the future of Lexus sedans beyond the ES yet huh? :/

IS should have been released in 2024 but looks to be in 2025.

LS? Now that's a mystery.

You think we getting an EV IS for next generation? I mean, the current gen likely has another 2 years MAX and then it's out. Haven't had any trademark filings yet to imply anything new or EV like "IS450e" or whatnot :/

There are three confirmed electric sports cars, the Porsche and Alpine and Lotus twins. Makes sense for Toyota to have one.

2023 Toyota Yaris Cross debuts in Indonesia - DNGA B-SUV; 1.5 litre NA, hybrid; previews Perodua D66B? - paultan.org

The Toyota Yaris Cross has made its official ASEAN debut in Indonesia as a new B-segment SUV positioned above the Raize, which is the sister car to the Perodua Ativa we have here as well …
paultan.org paultan.org

The first time there's an engine of the NR engine family that's modified for hybrid applications, called the 2NR-VEX, produces 90 hp/67 KW and 121 nm/89 lb-ft of torque, hooked up to an electric motor that makes 79 hp/59 KW and 141 nm/104 lb-ft of torque, it uses the power split device/E-CVT just like the other series-parallel hybrids. No idea how its performance is like, most likely slow as sh!t as Toyota and Daihatsu know people from these parts of the world think needing to slam on the throttle just to get up to speed in regular street driving is a normal thing, when it isn't supposed to be.

Also just ignore the car's name, it has nothing to do with the Yaris Cross that has been developed by Toyota, this one is developed by Daihatsu but is being sold as a Toyota only model. Many car journalists in my country are now daydreaming about a Perodua version to get around my country's unfair taxes towards vehicles from foreign brands, seems like they have completely ignored the fact that to have a Perodua version, it must first have a Daihatsu version, but since it's only sold under the Toyota brand, the other 2 won't exist at all.
