Toyota Tundra

The Toyota Tundra is a full-size pickup truck manufactured in the United States by the Japanese manufacturer Toyota since May 1999. The Tundra was the second full-size pickup to be built by a Japanese manufacturer (the first was the Toyota T100), but the Tundra was the first full-size pickup from a Japanese manufacturer to be built in North America. The Tundra was nominated for the North American Truck of the Year award and was Motor Trend magazine's Truck of the Year in 2000 and 2008. Initially built in a new Toyota plant in Princeton, Indiana, production was consolidated in 2008 to Toyota's San Antonio, Texas, factory.

The first generation Tundra had many similarities with the older Toyota T100 and the compact Toyota Tacoma. These included the shared use of a 3.4L V6 engine which was the top-of-the-line engine in both the Tacoma and T100. The V6 engine would serve as the base engine for the Tundra, while a second engine was added, a 4.7L V8, the first V8 for a Toyota pickup. Model code XK30 denotes rear-wheel drive models, while XK40 is for four-wheel drives.

Publicly introduced in May 1999 as a 2000 model, the Tundra prototypes and "show trucks" were initially known as the T150. However, Ford and automotive journalists criticized the name as being too similar to the market-leader Ford F-150, and following a lawsuit by Ford, the production truck was renamed the Tundra.

The Tundra was slightly larger than the T100. With a production capacity of 120,000, sales were double the rate of the T100. At its introduction, the Tundra had the highest initial vehicle sales for Toyota in its history. It was selected as Motor Trend's Truck of the Year award for 2000 and Best Full-Size Truck from Consumer Reports. It was assembled in a new Toyota plant in Princeton, Indiana.

Engine choices available in the Tundra were a 24-valve 3.4L V6 engine 5VZ-FE that produced 190 hp (142 kW) and 220 lb⋅ft (300 N⋅m) of torque and an LEV certified 32-valve 4.7L "i-Force" V8 engine 2UZ-FE that produced 245 hp (183 kW) and 315 lb⋅ft (427 N⋅m) of torque. The 3.4L V6 was only available until 2004 and the V8 was upgraded for the 2005–2006 model years alongside a new V6 shared with the Toyota FJ Cruiser.

A Toyota Racing Development (TRD) supercharger was already available for the 3.4L V6 (2000–2003 models) that bumped power to the 260 hp (194 kW) range and 260 lb⋅ft (353 N⋅m) of torque. TRD introduced a second supercharger option for the V8 (2000–2003 models) engine late into its second year of production that increased power to the mid 300 hp (224 kW) range and torque to the 400 lb⋅ft (542 N⋅m) range. The supercharged V8 was dropped when Toyota released the updated VVT-i-equipped 4.7L engine in 2005.

The grille was updated in 2002 (for the 2003 model year), along with a new Stepside bed available on Access Cab models. The Tundra Double Cab, also added to the lineup in late 2003 for the 2004 model year, was a crew cab with four rear-opening doors, with many interior and exterior details brought over from the Toyota Sequoia. Its bed was nearly 5 in (127 mm) longer than the competing Nissan Titan or Ford F-150. It is also 13 in (330 mm) longer, 3 in (76 mm) taller, and 4 in (102 mm) wider than the Regular and Access Cab versions, with a 12 in (305 mm) longer wheelbase. The Double Cab was only available with the V8 engine, and carried chassis codes UCK31/41, depending on whether it was equipped with four-wheel drive.

The new V6 engine was introduced in 2005, an aluminum-block 4.0L 1GR-FE rated at 236 hp (176 kW; 239 PS) and 266 lb⋅ft (361 N⋅m) of torque. Also in 2005, the existing 4.7L V8 was updated with Toyota's VVT-i variable valve timing technology and was rated at 282 hp (210 kW; 286 PS) and 325 lb⋅ft (441 N⋅m) of torque while the 2006 versions were rerated at 271 hp (202 kW; 275 PS) and 313 lb⋅ft (424 N⋅m) of torque. The engine however was the exact same for both these years and the rerating was only due to a change in industry standards for how data was determined. Therefore the down-rated changes for 2006 were not actually mechanical in nature.
