shame that we do not have 8GR-FXS in any car lighter than LS/LC. With GS gone, there is a need for IS 500h/RC 500h. But it is mostly interesting for European market with high petrol prices. In North American market most will pay for the better performing V8 for same price, even if less fuel efficient.

I want to see acceleration comparison to 250 km/h or at least 200km/h between GS 450h and new NX 450h+.
Premium fuel is expensive here in Canada too but is a smaller market bordering the US.

I balk having to pay premium but someone did point out all Lexus hybrids so far run on regular. :)

I believe this powertrain (RAV4 Prime/450h+) is limited to around 190km/h.

I have not looked in detail, I might be mistaken, but European Commission pushes for cars to be limited at 180 km/h. Don't know from which years. Makes the low top speed of BEVs look good compared to ICEVs. With BEVs accelerating so fast, it will make sense to add 0-180 km/h times.

Just want to mention: If all things "future Toyota and Lexus" are of interest to you, please take a moment to check out the latest LXE Podcast as it reviews the trip to Plano, TX, for the Product Showcase Event!


If you’re a Toyota or Lexus enthusiast, this is the podcast you simply cannot miss. After attending the recent Product Showcase Event in Plano, TX, we take you under the hood and behind the curtain with sneak peeks and special insights including:
  • We finally got the answer: When and where is the Lexus LF-1 Limitless?
  • Confirmed: The first dedicated all-electric Lexus will be here in 14 months.
  • Will electrification come to future Lexus’ F products?
  • Hands on with the 2022 ES, IS 500 F SPORT Performance and NX.
  • F SPORT Performance vs. F: The differences are immediately clear on the track
  • Seat time in the 2021 LS 500 F SPORT: Did the refresh do enough?
  • Driving the Toyota Mirai – did it really start life as the fifth generation GS?
  • Seeing the 2022 Tundra in person, and Lexus discussing whether or not they would build a luxury truck.
  • First hints on the next-generation Sequoia, GX and 4Runner.
  • Is Lexus considering building off road trims – similar to TRD PRO – for their next-generation SUVs?
  • Driving the LC 500 and Supra back to back on Eagles Canyon Raceway: Which is really the better sports coupe?
This and so much more, on the latest episode of the Lexus Enthusiast podcast. You can subscribe to the podcast in iTunes, listen on Spotify, or download the MP3 file directly. Hope you enjoy listening, and please let us know what you think on our new Podcast forum!

Does anyone know if the 1.2l turbo 8NR-FTS' replacement still happening? Last time we were discussing about a 3 cylinder 1.5l turbo.

If you look at what is going on in the industry, V8 is really dying, it is the new V12. Maserati is going with the 90° TTV6 in all its new cars, Ferrari has just unveiled its new 296 GTB with 120° TTV6 Hybrid making "combined" 830 PS using a 7.4 KW/h battery, the same configuration with 120° TTV6 Hybrid with 7.4 KW/h battery in the McLaren Artura. The TTV6 Hybrid replace the TTV8, they have about 25km of electric only range, probably less.

Lexus F and F Sport Performance models just cannot afford to not have any form of hybridization. Remember that latest unheard rumors of LC F was it was redeveloped again to use V6 Hybrid. Mercedes AMG goes Hybrid too, while Audi gets out and goes electric only.

This new bipolar NiMH battery on Aqua is actually quite a big innovation. I'm happy to see instead of a boring larger Yaris hybrid Toyota actually has something new to offer.

>> In a bipolar battery module, individual cells are stacked directly on each other thanks to the bipolar electrode. This way the modules can be much smaller and require fewer components.
>> Because current flows directly across the entire surface area of the current collector (instead of through wire connections), current density can be a lot higher. Losses will be lower because resistance is lower.

>> Each battery module is a large plate of stacked cells instead of cylindrical/prismatic/blade shape. This way the packaging efficiency can be very high and there's more surface area for cooling.
>> I don't know the exact specifications but from the image it looks like there are 7 modules each with 24 stacked layers (168s1p, 201.6V). Gen 1 uses 20 modules each with 6 internal serial connections (120s1p, 144V).
A.jpg

The end result is 2.1x power output from the same volume (1.4x cells, 1.5x current/cell). Gen 1 Aqua has 144V 6.5Ah@25C so total output is only 23kW. On Gen 2 this number is 49kW, even higher than the 311V Li-ion pack used on LS/LC500h (44kW)!
This is why this new form factor is such a game changer. Without changing the battery chemistry they are able to outmatch the power density of Li-ion batteries. Now consider this form factor on BEVs, the charging speed will be much higher. The only drawback I see is a single point of failure will mean more voltage loss and each module will be more expensive to replace. But that is always the price you pay when going for more efficient form factors.
I think Toyota uses NiMH chemistry to test the feasibility of this new technology to use later on SSBs. I think this is how they will solve the low current density problem with SSBs. Bipolar electrodes are relatively new with only lead acid chemistry available. Li-ion bipolar batteries only started development very recently.

Corolla Sport GR expected specifications
・ Overall length x width x height: 4375 x 1810 x
1450mm
・Wheelbase: 2640mm・ Vehicle weight: 1340kg
・ Engine: direct 3, 1.6L direct injection turbo
・ Maximum output / maximum torque: 300ps / 37.7kgm
・ Drive system: 4WD
・ Transmission: 6iMT
・ Suspension (F / R): Strut / Double wishbone
・ Expected price: 5 million yen

How accurate do you think these stats are? IMO the kerb weight seems unusually light for a modern C-segment AWD hot hatchback.

The regular Corolla Hatch is 3,060lbs, so assuming it lost ~100lbs while adding AWD seems unlikely to me, but then again, I guess it's possible that the 3cyl and its components weigh less than the 4cyl. Maybe it checks out after all?
