Toyota Announces Diesel Engines For Tundra And Sequoia

[dascrow]

During an international media reception last night at the Detroit Auto Show, Toyota Motor Corporation President, Katsuaki Watanabe, announced the release of a diesel motor for the Tundra pickup and Sequoia SUV. "First, I am happy to confirm that a new clean-diesel V8 engine will be offered in both the Tundra and Sequoia in the near future." Below is a press release from the event last night.

Detroit - Toyota Motor Sales (TMS), USA, Inc., held a media reception tonight at the 2008 North American International Auto Show at which Katsuaki Watanabe, president of Toyota Motor Corporation (TMC), announced a wide-ranging environmental agenda in response to the company's sustainable mobility vision.

Watanabe confirmed that a new clean diesel V8 engine will be offered in both the Tundra and Sequoia in the near future. By 2010, Toyota will accelerate its global plug-in hybrid R&D program. As part of this plan, Toyota will deliver a significant fleet of plug-in hybrid electric vehicles (PHEVs), powered by lithium-ion batteries, to a wide variety of global commercial customers, with many coming to the U.S.

To make that happen, Toyota has already started the planning phase to expand its Panasonic joint-venture battery factory. The expansion will add an assembly line to build lithium batteries for automotive applications.

Finally, Watanabe invited the media to attend next year's NAIAS, where Toyota will stage the world premieres of two all-new, dedicated hybrids, one for Toyota and one for Lexus.

"These two introductions will move us closer to our goal of selling a million hybrids per year in the next decade," said Watanabe.

Dascrow,
Is the diesels for more pulling power? Being that diesel cost more than gas why buy diesel? Does it have better mpg? I have a 07 Crewmax Limited. I was looking forward until recently the Tundra Hybrid. Now that has been scrubbed. I'm lost in that.

Diesels get better gas mileage- a company I worked for during one summer in high school (2 years ago) had 2 new Silverado HD 6.0 (gas) engines that got about 12mpg at best, and one 6.6L Duramax (diesel) that would get 20ish mpg on the highway, stock. The trucks were all base model other than that, 4x4 autos.

Oh, and the diesels pulled WAAAYYYY better than the gas engine. And if you do some research on diesels, you'll find that a tuner can produce anywhere from a 150hp increase (handheld/plug-in) to a 250hp increase (custom tunes) over stock, which makes for an extremely badass truck lol. IMO, Diesel>Gas (if price is equal)

aaron,
I don't know anything about a tuner for a vehicle. Really never heard of it. I'm just a shade tree mechanic minus the mechanic.

Diesels are gretat for pulling power and torque, also they engine last way longer. MPG are also improved, for example my buddy has a 6" lifted Duramax Turbo Diesel, intake, exhaust and a Banks Programmer, he is making over 600 lb feet of torque and is always out Bass fishing competitively, pulls his boat with it and averages about 22 mpg with his boat on the back.

[THEGOLDPRO]

main reason the diesels are better for towing are that for one they usualy make more tq, and 2 the tq curve is alot lower then a gas, while a gas engine will make say 400ft pounds at 3500 rpms, a diesel would make it at 1500rpms, so you have power down low for pulling.

[THEGOLDPRO]

for instance here are the specs on the two dodges i own, i have both are 1998's one is a cummins turbo diesel, one is an 8.0 litre v10 gas engine.

while the v10 makes more power then the diesel the diesels power comes on alot earlier.

ISB With Automatic Transmission CUMMINS TURBO DIESEL)
Peak Torque: 420 lb-ft (from 1600 to 2700 rpm)
Advertised Power: 215 hp @ 2700 rpm
Governed Speed: 3200 rpm
No Load High Idle: 3500 RPM


and the specs for my v10.
Horsepower 310 hp @ 4100 rpm
Torque 450 ft. lbs. (617 N.m) @ 2800 rpm


so while the v10 makes more power, te diesel makes the power down low, therefore it tows better then the v10.

Plus, you treat a diesel engine right and it will out-live you.

this is also true, my last dodge was a 92 cummins, and the truck rottod out around it but the engine and trans were like brand new, i ended up selling it to some young kid with 350k and a cracked frame, thing ran like it was a new truck, not to mention it was a primary work truck, for towing lanscape trailers and plowing snow, since it was new and never gave me any problems.

And diesels are incredibly easy to add power to. Just give it some more air and fuel and maybe a programmer and your pushing a good deal of power.

This is the announcement that I have been waiting to hear! While I have a 2003 Ford Excursion with the 6.0 liter diesel (Gale Banks 6 pack, Banks 5" exh, different intercooler, etc - puts out around 520 hp with close to 800 ft. lbs of torque) and a 2007 Tundra Double Cab 5.7. I want a Excursion replacement..... Sequoia would be GREAT in a diesel! My Excursion gets around 23-24 mpg as long as I don't run over 78 mph, then it drops to around 20...., but at the end of the day it's a Ford.....

I hope to hear more about the diesels in the future!

Please keep me posted,

Milton

Here's some interesting facts from test results reported in the Sept '07 Consumer Reports.

Overall MPG (no load)

Tundra 5.7 15
Chevy 6.6 TD 13
Ford 6.4 TD 10
Dodge 6.7 TD 13

Highway Towing MPG (7400 lb load)

Tundra 5.7 8.5
Chevy 6.6 TD 10.5
Ford 6.4 TD 9.0
Dodge 6.7 TD 10.0

Acceleration Towing 0-60 (7400 lb load)

Tundra 5.7 16
Chevy 6.6 TD 17
Ford 6.4 TD 19
Dodge 6.7 TD 19

IMO, Tundra 5.7 holds it's own very well with diesel p/u's, at least with the 3/4 ton diesels. It costs an extra +/- $8K to say Turbo Diesel on the fender, fuel is +/- $0.40/gal more than gasoline and oil&filter changes are +/- $100 vs $30.

Stock for stock, the Tundra will definitely hold it's own against diesels- tune a diesel (and the tundra, for consistency) and the diesel will probably do literally everything mentioned much better. The only major downside to diesels is the very high weight (if you off-road or anything) and usually a 3/4 ton or 1 ton will have a worse turning radius than a 1/2 ton.

With regard to the downside of a diesel, you forgot one thing........klak, klak, klak, klak, klak, klak, klak, klak.

My last 3 trucks have been turbo diesels. Both Ford and Chevy. I now own a gas powered Tundra.. The fuel economy for my last diesel has droped over the 3 years, ( 9 city 15 hwy )dealer said it was due to the additives they use for cleaner air. Additives are also the reason diesel is 4 bucks a gallon in So. Cal. So I said good bye to those 350 dollar oil \ gas filter changes and the 100 + fillups and HELLO GAS TUNDRA !!!!!!!!
