Pickup trucks at Toyota include the compact-class of Tacoma and a full-size pickup called Tundra. The Tacoma series, produced at a Toyota manufacturing facility in California, appears in Toyota's 2006 line with three cab sizes, two powertrain choices and options for rear-wheel-drive (RWD) and four-wheel-drive (4WD) traction. Tundra, assembled at Toyota's plant in Indiana, carries a V6 or V8 engine with Regular Cab and Access Cab configurations plus a larger four-door Double Cab.

Toyota's big trucks include the two-door Regular Cab, extended Access Cab and four-door Double Cab. Tundra Double Cab is bigger due to a wheelbase stretch plus inches added to track, width and height. It seats five and has a pickup box over six feet long. Stock engine is a big dual-cam V8 that displaces 4.7 liters and uses Toyota's VVTL-i (variable valve timing and lift with intelligence) valve wizardry. Output reaches 271 hp for 2006.

Tundra's Regular Cab and Access Cab versions list the V8 as an option and a 4.0-liter V6 at 236 hp as standard plus a manual five-speed or electronic automatic four-speed transmission. All Tundras can be outfitted with RWD or 4WD traction. The 4WD mechanism has an electronic transfer case with push-button convenience for switching between RWD and four-wheel high and low modes. Tundra has two trims available -- SR5 and the luxurious Limited.

Toyota reinvented this best-selling compact pickup last year and returns it for 2006 with a tire pressure monitor system (TPMS) added to all trims. There are three cabin designs with the two-door Regular Cab, extended Access Cab or four-door Double Cab. A 2.7-liter four-cylinder engine worth 159 hp is standard, but a 4.0-liter V6 for 236 hp is available.

Both RWD and 4WD versions are offered, as well as special editions like PreRunner and X-Runner. Prerunner with RWD traction has the look of a customized 4WD truck with a tall stance and flared fenders. X-Runner, a swoopy performance truck with ground effects and hood scoop added, draws its name from x-brace frame reinforcements to increase torsional rigidity. An optional TRD (Toyota Racing Development) Off-Road package for 4WD Tacoma adds a locking rear differential, progressive-rate front springs and Bilstein shocks plus big Goodrich Rugged Trail tires.
