I think this might have some validity if we look at ICE cars that have “forced” hybrid system into them but Toyota, GM (Volt & ELR), and Ford have shown hybrids increase efficiency of the vehicles with none of the issue you mentioned. The starters have not been shown to be common early failure points and rod bearing are failure points on GM ice vehicles…

Not sure I follow on this one as the benefit of a hybrid is you don’t have to adopt another “fueling” infrastructure.

I’m not here to debate hybrids vs ICE vs EVs… I guess I was just initially saying big vehicles could be more efficient with modern hybrid systems while increasing performance and I’m surprised more manufactures haven’t done it.
You have good points and I hope they can work out the physics.
Toyota has the best technology in this market and maybe they can improve the Sequoia to get better fuel economy and improve the payload/cargo space.
I am surprised/not surprised that Lexus is sticking to ICE for now.

The solution to running hybrid has always been like the train locomotives have been doing it. Toyota is deep into a tech of running a highly efficient tiny little engine that is designed to run at the most optimal Volumetric Efficiency, then they just keep it there while you are driving to power the system indirectly.

Most Lexus models are hybrid? 60% of sales are hybrids? Two references one is from Lexus Canada stating 60% of sales are hybrid and the other showing majority of RX sales are hybrid.

I was referring to their bigger SUV, the GX 550 models which are turbo 6 ICE.
They are very nice trucks but smaller than the Toyota Sequoia.
Not sure about the LX 600 which is a very nice luxury big SUV and I think it’s using the same turbo 6.

Ah! I understand now. The GX is the same as the current gen Land Cruiser but running the turbo 6 vs the LC that is only a 4cyl hybrid setup (differentiator in marketing). It is a smaller vehicle than then Sequoia and the LX has both ICE and hybrid versions (same setup as Sequoia/Tundra).

I believe they even were using the rotory for it. Like a little .3 liter wankle or something like that. We went too quickly from engines to electric. There were many things in between that would have done a lot to appease the environment panzies, while still giving us a benefit instead of wasted money just for the sake of the morons.

It blows my mind we still have pistons going up and down after 120 years, there are lots of ways to make things better without going full nonsense like plug in electric only.

There are hybrid options for those who want them but even Toyota who produces arguably the best hybrid vehicles can’t make a big truck/SUV that has the cargo room of a Tahoe or Yukon.

Fuel economy on a Sequoia is pretty piss poor for a hybrid and not any better than my Tahoe 6.2l V8.
Plus if fuel economy is a priority then you are not the target consumer of large body on frame trucks.
But my opinion is that they’re all doing hybrid wrong.

A small diesel motor geared only to an alternator and running all the time with a normal battery supplying power to an electric drive system would provide more than enough power and not even need a regenerative braking system.

The fuel capacity wouldn’t need to be redesigned and even with DEF it wouldn’t need much because it would always be hot. It would have torque for towing and acceleration and the range should be great based on tuning the RPMs for efficiency.

Trains have been running like this for decades with none of railroads investing to find better.

New gen of V8s is great but would really love to see these big V8s with a hybrid system integrated for better MPGs. 25mpg should be possible in today’s world…

I really want to see more plug-in hybrids. Most ppl don’t have commutes >30miles. Doing the whole thing on battery or even half of it would be ideal.
I don't like hybrids at all. Not only do you have the maintenance of an internal combustion engine but you also have a $12,000 battery that will need replacing. Give me all gas, or all electric.

I don't understand why a "big V8" would need a hybrid set-up; or vice versa.

AFAIK, all hybrids use small IC engines.

Most replacement are only $3-5k… $12k+ seems more inline with EV prices.

I think it would be a best of both worlds! Think about the torque curves: motors from 0-2k rpm then a combo from 2k-5k then the V8 power at the top end. The combo would increase power, performance (0-60 and towing) and efficiency.

Most hybrids don’t couple with big engines because most V8s are “old school.” The hybrids are being combined with new V6 and 4cyl options. So new V8s coming out, coupled with hybrid performance AND a V8 rumble… sounds good doesn’t it?

What does this even mean?

Typo and not a complete thought: Most hybrids are not coupled with V8s because the V8 are old designs and when modernizing the drivetrains the manufactures are downsizing in displacement and cylinders. Look at Ford Ecoboost engines. Went from the Triton V8s to the V6s then coupled with hybrids a few yrs back.
Same with Toyota and the Tundra. No more iForce V8 and in with the twin turbo V6 + hybrid. There is design that has to go in to ensure the engine and motors work together in harmony. Maybe there is something that V8s don’t pair well with hybrid setups. I’m not an engineer.

Hope that adds clarity.

Sorry, Man, your whole theory makes no sense to me.

Seems to be a lot of confusion here about the true purpose of trucks and the requirements to meet those needs.

We have a Lexus hybrid and with nearly 200k on it the battery is still fine (2012). I think my scanner says battery life is still 40%.

I also will admit the YouTube ppl make things overly simple but even the Tahoe/Escky hybrid uses Toyota style cells and are rebuildable. I would replace the battery pack in the Lexus with a re-conditioned one for a $3-4K. No different that the 6L80/90, 8L80/90 transmissions in the GM trucks. Similar price to fix/replace and the trucks take a similar hit on value when they fail. The battery packs actually look easier… idk. I think there are enough vehicle to show the technology is solid for 10-15yrs.
Again, NYC cabs are Prius, Escape Hybrids, and Siennas. They replaced the Crown Vic for a reason.
They return to a terminal at the end of every shift and only job is to move people around. Light duty.

Not necessarily. More and more of these vehicles are handed from one driver directly to another. Goal is 3 drivers for every vehicle.
Chief reason why this is still 'light duty' is TLC drivers strive to drive like 'hypermilers', even though hypermiling in NYC is infuriating for the rider(s) and other drivers.
But even though it's light duty, these vehicles seldom accrue under 200 miles a day x 6 days a week = 4800 miles a month, often closer to 6000 miles a month.

At 70,000 miles a year, how long are those battery packs supposed to last again? Because most hybrids with defunct battery packs are torture to drive.

This is where my knowledge hits a brick (pun intended) wall. I was always under the impression batteries last longer when they are consistently run down and recharged (to that magic 80%). I don’t know what the perfect life expectancy is of the batteries.

Has anyone seen Edison Motors out of Canada? They are building some retrofits for big rigs to make them kinda like locomotives. Someone else already mentioned that and on their YouTube it looks like they want to expand into pickup truck retrofits too.

Corvette's E Ray and ZR1X sort of blows your theories out the door.
