Tundras came with a choice of two engines, depending on model. Base and SR5 trucks had a dual-overhead-cam, 3.4-liter V6 that produced 190 horsepower. A 4.7-liter dual-cam V8, standard in the SR5 V8 and Limited, developed 245 horsepower. Either a five-speed manual or four-speed automatic transmission could work with the V6, but V8 trucks were automatic only. For '05, the V6 is a 245-hp 4.0-liter, replacing a 190-hp 3.4. It comes with a 6-speed manual transmission, which replaces a 5-speed; or a 5-speed automatic, which replaces a 4-speed. The V8 is again a 4.7-liter, but it gains 42 hp for 282.
