A 300mi range BEV has a lot of money and weight tied up in battery capacity that is dead weight in 95% of driving and only helpful on a few road trips each year. Big batteries and PHEV both waste a lot of weight and money solving range anxiety. When we can get 150mi range @ 75mph topped up in 10 minutes time on a charger, battery packs will get smaller because that reduces cost (with bonus of reducing weight and increasing volume).EREV is a quite awkward way of solving range anxiety. It's not cost competitive for a passenger car because of unfavorable component sizing compared to PHV and BEV. You are spending a lot of money on components that are dead weight in 95% of driving and only helpful on a few road trips each year.
On the other hand, it's quite useful for commercial vehicle where cost of operations is much higher than cost of purchase. A zero emissions bus/truck could use battery in city driving and a hydrogen fuel cell extender for highway driving or quick regeneration. It's quite attractive since the bus/truck needs no charging/refueling stop to run a full day shift. The bus line requires fewer buses and the truck driver can cover more distance per day.
That's right. Bigger batteries go through fewer charging cycles in their lifetime so they have better longevity. It is still a big waste of resources and actually a valid argument against BEVs. Well to be fair we can keep going on and say this is an argument against cars in general, because most people in the world move less than 30km a day so they don't really need a car to begin with.@qtb007 , I agree with you that for the future and with better charging infrastructure we won’t need enormous batteries, but it’s also important to note that it’s harder to make a smaller battery charge faster without compromise longevity.
There’s always a trade off.
The crown once reigned at the top of the Japanese car world. This car, which was a symbol of wealth, has also been 65 years since its first appearance, and when the model cycle counted to its 15s, it has become rumored that it will be in danger of survival (it looks like the Edo bakufu ...).^translate would be nice.
Spring 22-23 Crown launch
Details please! Does the ES 500h come with a more powerful ICE -- larger, V6, turbocharged -- or more powerful electric powertrain -- plug-in hybrid?ES 500h is definitely coming, and quite soon. That is why ES got such a mild facelift, and next gen might come sooner than the usual life cycle. Still wondering about next IS and RWD/GA-L platform. What is the LS going to be? Even LS 750h will not be enough given it will weigh almost the same as LX 750h.
ES 500h will "kill" LS 750h sales the same way it "did" to GS. Acceleration will be almost the same till 100 km/h, ES will be lighter, as spacious, and much cheaper. And if they upgrade interior quality/materials/luxury, LS will have little to add for that much money.
Sorry for wrong use of "definitely". I have no insider knowledge. I am just saying what should happen based on info we already have. ES would get the same setup as RX 500h, no V6, but turbo I4 hybrid without plug.Details please! Does the ES 500h come with a more powerful ICE -- larger, V6, turbocharged -- or more powerful electric powertrain -- plug-in hybrid?

A marvel from Toyota. There are actually turbochargers in there!
This new v6 comes out of the gates with 416 horsepower and 442 ft lbs. Impressive. But is that all it can do?
The V35A Engine is one of the most electronically controlled engine we've ever seen. Electronic Coolant temperature control, Electronic Oil control, Electronic valve control. Electronic boost control.
Electronic everything.
Quad intelligent valve timing. High compression, Twin turbochargers, liquid temperature controlled intercoolers. This engine SCREAMS 650 horsepower.
But where is it?
Locked away in one of the most complex engine management calibrations we've ever seen, ever.
No worries though, we have already been dissecting the binary from the ECU since October 2018, and we're inching closer to releasing the worlds first V35A ECU tune.
Here is what we know.
- The Engine Management uses one of the newest Chipset's available, under the highest technology available by Renesas.
- The Chipset floating point precision is simply unbelievable in terms of processing power when it comes to this calibration
- The engine calibration uses the LARGEST (byte size) and (table size) we have ever seen in a modern day ECU. We know that you can find rather large ignition and fuel maps on motorcycles for example (where the dimensions of a table might be as big as 32x32). Yeah, well...That's a baby compared to some of the tables in this ECU.
- It uses a new and revised version of Toyota's complex 4th Dimensional (literally) table structuring, torque model and throttle control calibration logic.
- The Calibration is modeled not for maximum possible power, but smoothest and quickest possible response.
- The Calibration is throttle limiting. What does that mean? Ask the Lexus IS200T. That means there is tons more torque just a throttle angle difference away.
Useful information:
Toyota's newest tech is proving itself once again. These new ECUs are finally on par with what other modern day manufactures have been doing. Although, there are some manufactures that have used floating point precision since 2003, Toyota now uses it to a bigger scale than ANY manufacture has EVER done, EVER!
- The new ECUs Chipset was only recently released by Renesas, it's not some ancient tech like you see in the Toyota's out of the 2000s (all the way to 2017 If you're a Tundra).
But who cares about that stuff? Lets see some of the tables, in depth.
- The basics. Fuel stuff. Not too different from Toyotas Standard protocol for fuel. (Although there are many other components, like Wide Open Thresholds, 2D Fuel targets, Stoic Target, etc).
Boost Targets Controlled by Various sensors. (Temperature control)
And the Grand Finale (Not really) Table Ala. Gargantua.
This (and many more like it) are MASSIVE Floating Point Precision tables. This one table is big enough to fit an ENTIRE early 90s calibration inside. Overcompensating much?
We're actually happy to see this. This means Toyota takes their calibrations very seriously, and they simply don't mind going outside of the norm to ensure the most accurately calibrated table possible. Unlike some manufacturers that may stick to certain table sizes (like 16x16) or Ford..whose ignition tables are laughably small compared to calibrations of this day and age (Although to Fords credit the individual table is small, the actual ignition strategy is NASA level complex).
What does this mean for the future? We're working with our Distributor in Asia and will have some dyno testing done soon. Lets see what the engine that should of been in the new Supra can do!
The FWD 2.0 litre hybrid powertrain generates 146kW/197hp, delivering 0-100km/h acceleration in 8.1 seconds.
The AWD-i variant features an additional, powerful electric motor on the rear axle which develops and impressive 30,6 kW.
Hmm, on face value how would this shape up compared to the other hybrid systems that are also being used? Are we to expect a significant uptick in efficiency, battery range with this new revision, or is it simply a power bump?11kW more power from newer battery. E-Four changed from that lawn mower motor (which isn't that compact actually) to a usable 30kW motor.
I think we shall know more details about 5th gen HSD when they launch the JDM Noah.
