Next Odyssey to Use Cylinder Mang

Honda's Odyssey to get cylinder shut-off technology
By YUZO YAMAGUCHI | Automotive News
TOKYO - Honda Motor Co.'s new Odyssey will be powered by a 3.5-liter V-6 that runs on all six cylinders when accelerating and three cylinders when cruising.
The fuel-saving technology will be a first for a minivan. Chrysler's new 300C sedan is offered with cylinder deactivation.
The redesigned Odyssey is due this fall. Company sources say the minivan also will use what Honda calls "active noise" technology to lower vibration when the engine is operating with three cylinders.
The Honda sources won't say how much its variable cylinder management technology will improve fuel economy. The current minivan is EPA-rated at 18 mpg in the city and 25 mpg in highway driving. The sources also won't say whether the engine will be standard equipment on the remodeled Odyssey.
On the 3.0-liter, V-6 Japan-market Inspire sedan, the cylinder deactivation system gets 27.3 mpg. That compares with 21.9 mpg for the previous Inspire's 3.2-liter V-6 engine. The figures are based on Japan's so-called 10-15 mode test, which is not directly comparable with mileage tests elsewhere.
Honda won't use the technology in the Acura TL, the U.S. version of the Inspire.
General Motors and DaimlerChrysler AG also are embracing the concept.
The new Chrysler 300C has a V-8 designed with what DaimlerChrysler calls a multidisplacement system. It uses eight cylinders when climbing a hill or accelerating to pass. Once acceleration flattens, the engine switches automatically to a four-cylinder cruise mode.
General Motors says it will offer cylinder deactivation on many vehicles in the next four years, equipping both V-6s and V-8s with the technology
Honda officials say their new engine is quiet and smooth. When operating in three-cylinder mode, engine vibration is reduced by changing the crankshaft rotation speed and using an active control engine mount. In addition, a speaker generates a sound that cancels out noise - active noise control. Honda engineers say the driver is unaware of a change in the number of cylinders being used.
As a price-sensitive family vehicle, the Odyssey is not an immediate candidate for costly hybrid technology to improve fuel efficiency.
The remodeled minivan will retain the same general packaging as the current version. The focus will be on functionality, not styling, say sources. That contrasts with a Japanese version of the Odyssey, launched last October, that has a low roofline to give it a sporty look.
The U.S. Odyssey will not be the only Honda model to use the variable cylinder management technology. At the Detroit auto show in January, Honda said it would use the system in a hybrid version of the Accord due this fall.

In real life suburbia, where the soccer mom uses it to run errands, it will not be cruising much at steady speed to make gains in fuel milage. Except for some salesman who spends countless miles on interstates at steady speed this won't make much of a difference.
Something doesn't sound right - the Inspire is the JDM version of the USDM Accord not TL.

Maybe so biker, but I can tell you that the wife and I would LOVE to have this upgrade for all the highway trips. It is a bit disappoiting to here it won't also get the hybrid treatment like the Accord ... of course if it did them my wife might be getting a new van ... now we can wait a few more years
