Interesting bit of tech in the new GM V8s to increase fuel economy.
I'll believe it when I see "it", meaning any improvement in fuel mileage and/or performance. :( My 2012 Silvy has fuel management and honestly I see no advantage at all, in fact the truck gets slightly
less fuel mileage overall than did my previous 2006 Silvy and 2005 Avalanche, neither of which had any sort of cylinder deactivation system but both of which ran the same 5.3L engine and same 3.42 axle even though they also both had the older wide ratio 4-spd transmission that supposedly wasn't as efficient as the narrow ratio 6-spd I have in my current '12. I see this stuff more as fluff for sales brochures, not an actual on road performance improvement for owners.
