I have seen a few threads speculating about when the next redesign of the Tacoma will be. I recently found this article at the following website: http://www.toyoland.com/future.html I should warn you that I don't know how accurate it is, and the writers may be speculating themselves. Also, please note that the years listed in the article are the model years, and not the actual physical years. So, the 2013 Tacoma should be released sometime in 2012. The article was updated on September 8, 2008, and here is the portion that concerns Toyota trucks, the Tacoma information is about halfway through the article:
Toyota Truck Updates
The Toyota Tundra has an optional 381 horsepower V8, beating every domestic truck engine in horsepower (the Dodge by 1 hp), and is a true American-style full-sized pickup. Built in the United States, it may get a heavy duty model (three-quarter or full ton), necessary for that “macho” image so important to American commuters, in three or four years. In the meantime, a new 4.6 liter V8 will become the base engine in 2010, adding around 30 hp and 2 mpg.
The big 5.7 liter V8 is also be used in the Lexus LX570 and probably the next generation Land Cruiser.
The Tundra may benefit from Toyota’s acquisition of chunks of Isuzu; the Isuzu diesel engineers are far more advanced than those at Toyota, and were the main brains behind the successful GM Duramax engines. A diesel engine using Isuzu technology should end up in the Tundra sooner rather than later - possibly at about the same time GM and Dodge bring out their diesel-powered 1500 models. For serious American fleet buyers, the diesel is a very popular option, because it requires less maintenance, provides more grunt, and consumes far less fuel, cutting fuel bills nearly in half in some cases (and farmers can make their own biodiesel). Again, diesels also boost the “rough and tough” image.
The Tacoma is due for redesign in 2013.
Despite a bigger Sequoia taking over the Land Cruiser's market position, the Land Cruiser itself will hold on, supported by international sales, with a redesign scheduled for 2009. At that time, the 5.7 liter engine is likely to appear with 380 horsepower; the fancy Land Cruiser, or Lexus LX570, already uses that engine.
The FJ Cruiser was scheduled for a 2012 redesign, but it may simply be dropped due to falling sales.
The new Sequoia will take advantage of all Tacoma upgrades, and will also reportedly feature a new independent rear suspension. Interior space should increase as well. It is to be made larger and more powerful - following the Tundra it’s based on. Like the Tundra, it will get a new 4.6 liter V8 in 2010.
The 4Runner, just redesigned for 2006, will be re-engineered again for 2010.
