In 2000, Toyota released the all-new Tundra full-sized pickup truck, created to compete with other leading brands. It offered two and four-door options with various cab and engine choices available. The TRD Off-Road package was introduced in 2001, with updates to the V6 and V8 engines and two new body colors. SR5 models got new 16 wheels for 2002, while the V8 models got a limited-slip differential.
The StepSide model sport trim was added in 2003, with all models featuring a new front fascia, antilock brakes and updated interiors. For the 2004 Tundra, the new four-door dual-cab model was added to the lineup. The base engine was updated in 2005 to boast a 4.0-liter V6 engine that got 245 hp. Updates to all trim levels were made, including new headlamps, new tail lamps, a JBL audio system, new gauges and new optional GPS system. A redesign Tundra graced showroom floors for 2007, offering a more rugged and sturdier frame, more interior options, three beds, three engines and three cabs to choose from, including a new 381-horsepower 5.7-liter V8 engine.
