Changes for 2010 include the addition of E85 compatibility and variable valve timing to the 4.8-liter, 5.3-liter and 6.0-liter V8 engines. Savana 2500 and 3500 models now feature a new six-speed automatic transmission, a revised rear axle ratio and a remote start option on the LT trim.
Changes for 2009 include the addition of an engine oil cooler on the 4.3.-liter V6 and a transmission oil cooler on applications with a 14,000 pound or greater GCWR. A fast idle option is available on 6.0-liter V8 models, making it easier to run accessories while the van is idling.
The reality is that the aging GMC Savana has been surpassed when it comes to people- and cargo-carrying duties. Newer vans from Mercedes-Benz, Nissan and even Ford offer new architecture with more interior space and better fuel economy. However, the 2015 GMC Savana offers up some big advantages of its own. First, it's considerably less expensive than those newer vans, especially the Mercedes-Benz. Second, that it has been around forever means there's a ton of aftermarket parts for customization, or "up-fitting." You can get passenger, cargo or "cutaway" versions, and all-wheel drive (AWD) is available with some of the many engine combinations. It's also one of the few vans that can carry up to 15 people right from the factory.
