Found a nice piece on Autoblog with an article from 7tune, I am at work now and have 'Fortiguard' which is blocking the site (7tune) stating that it contains explicit material, so I will provide the link to the site. www.7tune.com/2010-acura-nsx/ is the link to some more renderings."is news that the 5.5L V10 engine expected under the hood of the supercar will include relatively aggressive cylinder deactivation technology. The V10 will reportedly be able to cut its cylinder count in half by running as a 2.75L inline five-cylinder when its full capacity isn't needed. We would imagine that would be quite often, as the car's expected power output of six-hundred horses attests."
