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.

Toyota Tundra Diesel Dually Project Truck
"Road Warrior" exterior combined with luxury Interior

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.
