Yes GM does have active fuel management but my 2010 4.8L does not! It's been around since 2010. I've had this van for 3 years now- it's got `140K and has been very reliable - I love it. They keep updating the engine/tranny but the body hasn't changed for decades. It think it may be setting a record! I'm 6'6" to and am okay getting in and out but there's no doubt that things have changed a lot and the van is in need of some serious updating - which I hear is not going to happen for at least three years. I strongly considered the NV - I liked the ride, I liked the seats, I liked the engine, I like the thought that went into it...I was worried about the cargo space and the prices were a little high for me and the GMC/Chevy's were abundant and more affordable. I didn't realize until later that a high top NV has about the same amount of cargo spaces as and extended Chevy/GMC van. (Who knew?) If I found a high-top in my price range I could have ended up with an NV. I plan on driving this for another 4 years or so and then seeing what's up. I read that Nissan is disappointed at the sales of the van. I sincerely hope they keep with it. It and the Chevy/GMC are the only two vans that really have what I want for a lot of off-road travel - decent clearance, tough ladder frame chassis, big enough tires (love those 17"er's on the biggest Nissans),and reliable. The downside conpared to the Transit (low clearance, small tires) and Promaster (reliability problems I've heard) is low MPG and less space. I was in a Promaster the other day and couldn't believe how much room there was.
