A note from the Editor: with the new Tacoma coming to market with an Atkinson cycle engine, we thought it made sense to republish this older post that explains how it works.
When rumors of a V8 Lexus coupe with “variable displacement” hit the automotive press a few months ago, I was more than a little skeptical. Quite a few Toyota employees have said that the typical variable displacement technologies employed by GM and Chrysler-Fiat are “not in the best interests of the consumer,” which is Toyota-speak for “variable displacement is a stupid gimmick,” at least when GM and Chrysler-Fiat do it.
Considering all the problems GM trucks have had with their active fuel management systems (which can consume 1-2 quarts of oil between changes), Toyota’s stance makes sense. Yet a number of sources claimed Toyota’s new V8 Lexus coupe would have variable displacement technology, and I found myself a bit dismayed. Would Toyota succumb to the allure of variable displacement systems that raises a vehicle’s EPA rating without any real-world benefits?
Fortunately, the answer is no. The new Lexus RC F comes with a 5.0L V8 that can operate both as a traditional Otto cycle engine and as an efficient Atkinson cycle engine, which – in a manner of speaking – means the engine is variable displacement. When you combine this news with today’s announcement from Toyota about a “new series of gas engines,” it’s safe to say that the Tundra will be getting a variable displacement V8. Probably in the next 2 years. Read more…

The first full year of the 2014 Toyota Tundra redesign sales are in the books and they are mixed. While Toyota nearly hit their sales target, this target was really conservative to begin with.
