Acura NSX V10 May Get Cylinder Deactivation, Acura RL May Get V10

According to 7Tune, Honda is concerned about their environmental image with the new 5.5-liter V10 they plan on dropping between the rails of the new 2010 Acura NSX. We're now told Honda plans to employ "Variable Cylinder Management" to deactivate an entire bank of cylinders in the V10 in cruising situations to greatly improve fuel economy. That's all well and good, but what do the prospective power numbers look like on this new engine? And what of other rumors for the big V10?

The speculation on power is unconfirmed at this point, but sources are placing the figures at around 590 HP and 430 lb-ft of torque. Considering the original got up to about 290 HP and 240 lb-ft of twist, this represents one hell of an upgrade. Speaking of upgrades, the other rumor we're hearing points to the possibility of some form of special 2009 Acura RL fitted with the same NSX V10. Obviously such a car would bend our fragile little minds to the breaking point and cause droplets of sweat-like dew to form on every other performance sedan's hood. Although this'll certainly help potential RL buyers interested in performance, unless it comes to market with a less-toothy grille, it won't do much for those looking for something better to look at.
