According to InisideLine, Toyota is working on a family of clean diesel V8 engines for its Tundra pickup and Sequoia SUV. A 4.5 liter unit is expected to enter production and hit the market for the 2010 model year of both vehicles. Toyota will also offer a new version of its existing 4.7 liter V8 E85 ethanol engine as well.
Sources said that Toyota is working on at least two variants of the clean diesel V8 including the 4.5 liter unit and a larger 7.0 liter V8. The 7.0 liter V8 diesel will be fitted in the heavy-duty edition of the Tundra which is expected to enter production in 2011 or early 2012.
As reported last week, our northern neighbors are expected to get a 4.5 liter V8 diesel in the 2009 Land Cruiser. The engine is expected to produce 280-hp and 520 lb-ft of torque and returns a combined fuel-economy of 22.4mpg for the Land Cruiser.
Sources said that as of right now that engine does not meet Tier 2 Bin 5 standards and that a cleaner version of that engine will arrive on the stateside later next year. So yes, we’re guessing that’s what InsideLine is talking about here.
