Default Toyota FINALLY Embraces Turbocharging

A long-standing rumor indicates that Toyota plans to replace its naturally aspirated V8 with a turbocharged V6. As an example, leaked info about the new Land Cruiser suggests it adopts a 3.5-liter V6 with forced induction that makes 409 hp (305 kW) and 480 lb-ft (650 Nm).

The other powertain is the bigger mystery. "We have our concept and our own technology that I think you'll be impressed," Carter told Motor Trend. "We're in it to win it."

https://www.motor1.com/news/512487/t...upgrade-rumor/

New Toyota Tundra Has Two Awesome Engine Options

Will a V8 be one of them?
The long-overdue next-generation Toyota Tundra is just around the corner. It's highly possible it'll be unveiled later this month, though Toyota has yet to confirm a specific date. Until then, more details are coming out about the third-generation full-size Tundra and it'll be well worth the long wait. Speaking to Motor Trend, Toyota's executive vice president of sales for North America, Bob Carter, confirmed the next Tundra will have two engine options.

The naturally aspirated 5.7-liter V8 will not be one of them, which comes as no surprise. Instead, the base engine is a "core powertrain that's substantially more powerful in terms of horsepower and torque than the current V8," according to Carter.

As a reminder, that V8 tops off at 381 hp and 401 lb-ft of twist. Carter didn't state whether the new base engine is a twin-turbocharged V6 or V8, but we're betting on the former. The optional engine, meanwhile, "will blow you away," the executive bragged. Unfortunately, he didn't go into detail but there's a pretty good chance it'll have some form of electrification or even a hydrogen powertrain.

Toyota previously confirmed plans to launch both battery-electric and hybrid trucks but we don't know if it was referring to the Tundra's optional engine. Full engine details are due in September and sales are due to begin in December.

Production will take place at Toyota's San Antonio, Texas facility that's currently tasked with building the Sequoia SUV. "We have our concept and our own technology that I think you'll be impressed," Carter added. "We're in it to win it."

That's a very confident thing to say in light of new competitors like the Ford F-150 Hybrid and F-150 Lightning. A facelifted Chevy Silverado 1500 and GMC Sierra 1500 are also due for the new model year and, later next year, a fully electric Silverado will arrive. Toyota knows a thing or two about building pickup trucks so we're confident it'll deliver the goods.

This thread could have been started in 2011 and Toyota would still be late to the party.

Forced hydrogen induction?



Quote:
Your Future Hydrogen Fuel-Cell Car Might Just Have a Roots Supercharger
Looks like the ol' roots blower has found new life.


Hydrogen fuel cells require oxygen as a part of their operation—you have to flow air over them to make power. Honda and Hyundai both use electrically operated centrifugal-style blowers to get the air needed; however, Eaton thinks it can do better with the classic Roots blower, albeit driven by an electric motor. Toyota already uses one on its Mirai, and while it may not exactly be supercharging as we know it, it's still Roots-blown forced induction.

The company currently offers two different sizes of electric blowers for transportation applications: a 75-kilowatt unit and a 150-kilowatt unit, the kilowatt designation describing the output of the fuel cell itself. Both of them use four-lobed rotors with a twist of 160 degrees. Instead of a snout with a pulley at the end, the "TVS" blowers modified for fuel cell application have 300- to 450-volt DC electric motors mounted straight to the housing.

Eaton says it currently supplies its fuel cell superchargers to companies making hydrogen buses, although it would like to increase its sales volume and move onto more mass-market vehicles soon. The Drive reached out to Eaton to ask what the advantages of a Roots-style air pump are for fuel cell applications versus the more popular centrifugal type, but we've yet to hear back. If we had to guess, It would likely be cost and low-speed efficiency—Eaton says its units can operate below 14,000 rpm, which is much less than a centrifugal-type air pump.

Remember when a twin turbo V6 was something special?

Kind of a retarded thread as Toyota has been using turbos for 40 plus years now...

Not really in volume applications. The MR2, Celica All-Trac, and Supra sold in minute numbers.

Still rocking the 2008 Tundra I bought new—I continue to love it and it’d be the last to go if I had to liquidate the fleet.

For me, when it comes to pickups/suvs, if it has a turbocharger, it better not have spark plugs... .

But I doubt that is the big surprise engine.

Maybe the Tacoma will get some love and upgrade to disk brakes in the rear. They still use drums, correct?

The nx200t was turbocharged. not sure how well that thing sold though, I don't see many of them around. Briefly looked at buying one, but moved along.

There's a lot more Toyotas that came with turbos than just the ones you listed. It's not Toyota's fault Amerifats don't want 3/4 of Toyota's vehicle lineup.

If at any time you would have visited Japan over the last 25 years, you would have noticed than roughly 25 to 35% of the Toyotas on the road there are either Turbocharged or Supercharged. The road tax over there is based on engine displacement, all the JDM manufacturers "FINALLY embraced turbos" in the early to mid 80's.

It made zero sense for Toyota to start sending turbo people carriers to the US until now, and only now just because of the ever tightening CAFE standards. Turbos add heat, weight complexity, and cost, for a small boost in MPGs over a larger NA engine. Gas is so cheap here that it just made more sense to offer a NA engine over a turbocharged one.

Can you list these high volume vehicles Toyota sold in other markets with turbocharged engines?

You probably right.

Atleast the Supra got a B58.

So not really much in the way of high volume seeing most of those models sold with NA base engines and the little NR engine is really the only one of note that was sold in volume. When I say high volume I mean high volume as in Ford using ecoboost engines in their volume sellers, VAG, BMW, MB, even Honda now primarily using FI engines.

Pretty sure the 1JZ was sold often enough to be volume.

As stupid as this may sound, for my next daily driver my final 3 contestants are an M340, a GLB35, and... a 96 Toyota Chaser Tourer V. Talk about cross shopping.

Those Chasers looked good in blue. Never did like the Aristos, but the Crestas and Chasers looked good and the 1J was nice.

IS200t also uses the same turbo motor. A few years ago the IS200t and NX200t were renamed to the IS300 and NX300 respectively, which both still use the same turbo motor despite dropping the "t" from the name. The IS sells pretty well from what I recall, someone correct me if I'm wrong.

My brother leased an NX200t for a few years. It was okay. Not terrible, not amazing. Just...average.

I believe the GS and RC models also had the same or similar turbo motor for the base model but I bet most people paying that kind of money probably opted for the higher trim V6 models.
