SEMA 2007: Toyota Tundra Dually Diesel

With a strong OEM presence at SEMA, automakers are forced to bring The Badass to the masses. Toyota has apparently been overrun with requests from customers for some form of diesel motivation in its Tundra pickup and the automaker has responded... sort of... with the Tundra Dually Diesel. Toyota utilized two Tundra CrewMax pickups that were joined at the hip to lengthen the frame and add an additional foot to the bed. Although the majority of the Tundra Dually Diesel is bespoke show material, the drivetrain has been pulled straight from a Hino medium duty truck, with the only exception being a custom split driveshaft.
The crown jewel of the Dually is a JO8E 8.0-liter inline six turbodiesel, making around 300 HP and 600 lb.-ft. of torque. Shoehorning that kind of mill into the tight confines of the Tundra proved to be a challenge. The body had to be lifted off the frame by three inches and after some hacking and chopping of the firewall, they were finally able to fit the 1,500 pound engine into the bay. Between fitting the oil burner into the snout and mating it to a five-speed Allison tranny, the interior accoutrements have suffered – the HVAC controls are nonfunctional and the massive stick is there to provide additional leverage when shifting gears.
Mike Levine has a great write up covering all the details of the Tundra Dually Diesel, which is worth a read. And even though this mutha' runs, don't expect a production version to make it to dealers any time soon.
We've added Toyota's press release after the jump.
PRESS RELEASE
Toyota Tundra Diesel Dually Project Truck
"Road Warrior" exterior combined with luxury Interior
10/30/2007
Making a bold and adventurous statement about the contrasts between rugged "Road Warrior" performance and opulent luxury, a Toyota Tundra CrewMax diesel dually project truck made its debut at the 2007 SEMA Show.
At its core, the Tundra light duty pickup's stock engine was replaced with a medium duty diesel powerplant plucked from a 35,000-pound commercial truck. The 8.0-liter inline six-cylinder high-torque engine, made by Toyota affiliate Hino, is mated with an Eaton five-speed manual transmission and a Hino back end. Toyota Motorsports Technical Group heavily modified the Tundra to accommodate the beefed-up driveline.
A host of custom exterior treatments point to the off-the-charts muscle under the hood. Prominent examples include forged aluminum alloy 22.5-inch wheels custom made by Alcoa, a diamond plate-lined bed, a charcoal gray metallic flat paint finish and a fifth-wheel hitch rated at 24,000 pounds.
The muscular theme on the outside shifts dramatically to that of luxury on the inside with hand-sewn ginger leather seats, suede pillars and headliner and dual rear captain's chairs with individual DVD entertainment systems.

It's about time! I own one of the last Toyota turbo Diesel pickups sold here in the USA in '85. Good work! I will be in line to buy one, IF they actually go to production.

I think they got tired of having Chevy lug their trailer around

The front has a ladder built-in. LoL.

Allison != Eaton.
The write-up states that the truck uses an Allison 5 speed (automatic), but the specs indicate that it uses an Eaton five speed manual.
While it might whisper blasphemy to have an Allison in a Toyota, it would have made the truck cooler.

This is a good start. I have to give them a lot of credit for effort and execution. I also really like the idea of the inline 6 turbodiesel.
Once all of the kinks and quirks have been worked out and the final model makes it into production then I will have to seriously consider one.
Maybe it's about time i consider owning a truck. If anything this will lead me closer to getting one.

Yeah, I'm quite happy with my inline-6 Cummins turbo diesel. :)
Gary Blomquist 8:40PM (10/30/2007)
Dodge has been using an inline turbocharged 6 cylinder diesel for many years called the Cummins 5.9 liter, and now this year it's a 6.7 liter diesel, and still an inline turboed 6.
GM and Ford both use turboed V8 diesels.

Man that thing is huge!
Do pepole really need these monster trucks?

Surprisingly, there are still places in this country where the ultimate dream is to drive a big truck.
Michael 12:57PM (10/30/2007)
Yes: farmers, ranchers, and people who need to tow huge trailers with a 5th wheel.
miklm 9:11PM (10/30/2007)
And don't forget guys like club racers who need to pull a big car hauler to the track on weekends. Race cars aren't exactly street legal, and you're not pulling a 36-ft Gooseneck trailer with a Ranger or a Frontier. And contractors that have to pull big equipment trailers around? Lots of people USE their big trucks on a daily basis.

Believe it or not, people actually do NEED trucks. Lets just pretend you go to a near by horse track to watch the weekend horse races. How do you think those horses got there? Did the jockies ride them there? No, they were in a trailer. Was this trailer attached to a civic, corolla, or cobalt? No. How about your house, who built it? Who mows your lawn? Who is going to remodel the inside of your condo? How is Bob going to take his boat, 4-wheelers, or camper up north? How is the farmer going to get the bailed hay back to the barn? And yes John, not only is it a dream in some "places" to own a large truck, but their lively-hood depends on it. I am going to guess you have not left the city in a long time, if ever. Try it, you will be surprised at how many people do NEED large trucks. And even if someone does not really need a truck, but has one just for the hell of it, who cares. I am sure you do not really need such a nice expensive plasma tv, fast car, etc.... But you have one because you want one.

Now if they could only get that damn tailgate to stay closed!!

Did anybody read this "1,500 pound engine"??
What kind of inefficient powerplant is that? 300hp/600tq while weighing 3/4 of a ton?
Please tell me this is a misprint.

Thats how much medium duty engines weigh. The Cummins weighs that much. The 7.3 Powerstroke was almost that much. Its a huge lump of iron that makes crazy amounts of torque.
As for the concept... The Dually flares are a bit close to the bed and would have looked more proportional on an 8ft bed. I do like how they go to the rear at full width, the bumper being widened in the step area. This could get in the way with some trailers, however.
As cool as the medium duty drive train is, I really wish they had decided to show the V8 Diesel from the Landcruiser.
Q: Whats that 4Runner looking thing with the FJ fenders in the background?
Jason 1:24PM (10/30/2007)
@Guenther: the Cummins and Powerstroke also put out more power than just 300hp/600ftlbs. I know that extra power is just a computer tune away, but if Toy wants to play with the Big Boys, they're going to have to bring more than just 300hp/600ftlbs, regardless of what motor they stuff under the hood.
The 6.7L Cummins and 6.4L Powerstroke both put out 350hp/650ftlbs, and the 6.6L Duramax puts out 365hp/660ftlbs. Even the previous motors were all over 300/600 I think.

@ Jason
For diesel heavy-duty applications maximum power output matters less then where in the power curve the torque comes.
Gary Blomquist 8:36PM (10/30/2007)
The diesels in the Ford, GM and Dodge light duty 3/4-1 ton pickups all weigh over 1,000 lbs, with the 6.7 liter inline 6 cylinder Cummins in the Dodge p.u. trucks weighing the most. I understand that it's around 1,200 lbs..

That is definitely a BAD ASS truck !

It sort of reminds me of the truck that Marty McFly has at the end of Back to the Future.
