Bigger, bolder Tundra pickup, slated for production in early ’07, is 10 inches longer, 5 inches higher and 4 inches wider than the current 7/8-size Tundra. Three cabs, two beds and two engines, plus three levels of cab trim, will comprise 30 different models, the company says. A new 5.7-liter V-8 and six-speed automatic transmission can tow a 10,000-pound trailer.
