No. 2: Saturn Vue Green Line

EPA-estimated mileage: 25/32

Dramatic mileage boosts get all the attention, but Saturn is onto something with this mild hybrid approach. The current Vue Green Line's premium over the lowest-priced gas-only version is modest — only 14 percent. All the same, its city and highway mileage increases are 32 and 23 percent, respectively. What's more, it's priced below the V-6 version, whose mileage it roughly doubles. The only drawback: The Vue is the only hybrid SUV not to offer all-wheel drive. (Note: A second Green Line with 2 Mode technology is coming late in 2008 as a 2009 model.)Visit now
