Washington DC November 5, 2007; The AIADA newsletter reported that at the Specialty Equipment Market Association show last week, Toyota Motor Corp. quietly parked in its display of wild tuner cars the Tundra Diesel Dually, a concept truck that could be a template for Toyota's entry into heavy-duty pickups.

According to Automotive News, the Tundra Diesel Dually is Toyota's challenge to the Ford Super Duty pickups, GM's heavy-duty versions of the Chevrolet Silverado, and Chrysler's heavy-duty Dodge Ram.

The Tundra Diesel Dually boasts an 8.0-liter inline-six turbocharged diesel engine, a lengthened Tundra frame, and an Eaton five-speed manual transmission.

Toyota has long been expected to build a big diesel-powered version of the Tundra, but the automaker had said only that it was studying the idea. The Diesel Dually, which features four rear wheels with 22.5-inch tires, shows Toyota could jump into the market quickly.

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.
